    Before: GARLAND, Chief Judge, TATEL, Circuit Judge, and
    EDWARDS, Senior Circuit Judge.
    Opinion for the Court filed by Senior Circuit Judge
    EDWARDS.
    EDWARDS, Senior Circuit Judge: By regulation issued
    pursuant to the Endangered Species Act (“ESA”), sport-hunted
    African elephant trophies may only be imported into the United
    States if, among other things, the U.S. Fish and Wildlife
    Service (“Service”) makes “[a] determination . . . that the
    killing of the trophy animal will enhance the survival of the
    species.” 
    50 C.F.R. § 17.40
    (e)(6)(i)(B) (“Special Rule”). On
    April 4, 2014, the Service issued a press release stating that the
    agency lacked sufficient information to support a positive
    enhancement determination with respect to elephant trophies
    hunted in Zimbabwe during the 2014 hunting season. The
    finding, which was subsequently published in the Federal
    Register, banned the importation of such trophies going
    forward from the date of the finding. The Service also made
    negative enhancement findings in July of 2014 and March of
    2015, each time concluding that information concerning the
    size of the Zimbabwean elephant population and status of
    conservation efforts in Zimbabwe did not support a conclusion
    3
    that killing the animal “will enhance the survival of the
    species.” 
    Id.
    Safari Club International (“Safari Club”) and the National
    Rifle Association (“NRA”) (collectively, “Appellants”) filed
    suit in District Court to challenge the 2014 and 2015 findings.
    Appellants claimed that the agency’s actions were arbitrary and
    capricious under the Administrative Procedure Act (“APA”)
    and violated the ESA because, inter alia, in its determinations
    to ban the elephant imports, the Service impermissibly relied
    on standards that are more stringent than the statutory
    requirements in the ESA. The District Court denied
    Appellants’ motion for summary judgment on these claims and
    granted judgment for the Service. For the reasons explained
    below, we affirm judgment for the Service on these claims.
    Appellants also contended that the Service erred in
    adopting the 2014 and 2015 enhancement findings without
    adhering to the notice-and-comment rule-making requirements
    of the APA. See 
    5 U.S.C. § 553
    . The District Court rejected this
    claim on the ground that the enhancement findings were the
    product of adjudications and, therefore, not covered by the
    APA’s rule-making requirements. The District Court erred on
    this point. Under the APA, a “rule” is “the whole or a part of
    an agency statement of general or particular applicability and
    future effect designed to implement, interpret, or prescribe law
    or policy.” 
    Id.
     § 551(4). And as the Supreme Court has
    explained, rule-making procedures are “used in the formulation
    of a basically legislative-type judgment, for prospective
    application only, rather than in adjudicating a particular set of
    disputed facts.” United States v. Fl. E. Coast Ry. Co., 
    410 U.S. 224
    , 246 (1973). The enhancement findings in this case fit
    these definitions of “rule” to a tee. Therefore, the Service erred
    in adopting the findings without first following the notice-and-
    comment rule-making requirements of the APA. Accordingly,
    4
    we reverse the District Court’s grant of summary judgment in
    favor of the Service on the § 553 claim. The case will be
    remanded to the District Court with instructions to remand to
    the Service so that it may initiate rule making to address
    enhancement findings for the time periods at issue in this case.
    I.   BACKGROUND
    A.   Statutory and Regulatory Background
    1. The CITES Treaty
    The United States and Zimbabwe are parties to the
    Convention on International Trade in Endangered Species of
    Wild Fauna and Flora, Mar. 3, 1973, 27 U.S.T. 1087 (“CITES”
    or “Convention”). See 
    16 U.S.C. § 1538
    (c)(1) (incorporating
    the Convention into U.S. domestic law through the ESA). The
    Convention regulates the international trade of imperiled
    species that are listed in its appendices, which include African
    elephants, or Loxodonta africana, from Zimbabwe. See, e.g.,
    
    id.
     §§ 1537a–1539; 
    50 C.F.R. § 17.11
    .
    As relevant here, Appendix I lists species that are
    “threatened with extinction which are or may be affected by
    trade,” CITES art. II(1), 27 U.S.T. at 1092, and Appendix II
    lists species that may become threatened with extinction unless
    their trade is regulated, 
    id.
     art. II(2), 27 U.S.T. at 1092. Parties
    to the Convention may not allow trade in species listed in the
    appendices except in accordance with the treaty’s provisions.
    
    Id.
     art. II(4), 27 U.S.T. at 1092.
    Appendix I species may be shipped internationally only if
    both the importing and exporting countries grant permits,
    which are subject to certain conditions. 
    Id.
     art. III, 27 U.S.T. at
    1093–95. Among the requirements for a permit to issue, both
    5
    countries must make a “non-detriment” finding, certifying that
    the trade in threatened species “will not be detrimental to the
    survival of that species.” 
    Id.
     art. III(2)(a), 27 U.S.T. at 1093;
    
    id.
     art. III(3)(a), 27 U.S.T. at 1093. Until 1994, the Convention
    also required an importing country to make an “enhancement
    finding,” a determination that “the killing of the animal . . .
    would enhance the survival of the species.” Retention of
    Threatened Status for the Continental Population of the African
    Elephant, 
    57 Fed. Reg. 35,473
    , 35,485 (Aug. 10, 1992). The
    parties to the Convention removed the enhancement finding
    requirement from the treaty by resolution in 1994.
    For Appendix II species, the Convention requires a permit
    from the exporting country only. CITES art. IV, 27 U.S.T. at
    1095–97. While subject to the non-detriment finding
    requirement, permits for Appendix II species have never been
    conditioned on the exporting country making an enhancement
    finding. In 1997, over opposition from the United States, the
    parties to the Convention transferred African elephants in
    Zimbabwe from Appendix I to Appendix II. Changes in List of
    Species in Appendices to the [CITES], 
    62 Fed. Reg. 44,627
    ,
    44,628–29 (Aug. 22, 1997).
    It is undisputed that the proscriptions in the Convention
    are a floor, not a ceiling, for protection of Appendix II species.
    The treaty “in no way affect[s] the right of Parties to adopt . . .
    stricter domestic measures regarding the conditions for trade,
    taking possession or transport of specimens of species included
    in Appendices I, II, and III, or the complete prohibition
    thereof.” CITES art. XIV(1), 27 U.S.T. at 1108.
    2. The Endangered Species Act
    Congress passed the Endangered Species Act (“ESA”), 
    16 U.S.C. §§ 1531
    –44 (2000), to provide for the conservation of
    6
    “endangered” and “threatened” species, 
    id.
     § 1531(b); see id.
    § 1532(6) (defining “endangered species” as “any species
    which is in danger of extinction throughout all or a significant
    portion of its range”); id. § 1532(20) (defining “threatened
    species” as “any species which is likely to become an
    endangered species within the foreseeable future throughout all
    or a significant portion of its range”). Except in narrow
    circumstances, the Act generally prohibits the importation of
    endangered species into the United States. Id. § 1538(a)(1)(A);
    
    50 C.F.R. § 17.21
    (b).
    For threatened species, section 4(d) requires the Service to
    “issue such regulations as [it] deems necessary and advisable
    to provide for the[ir] conservation.” 
    16 U.S.C. § 1533
    (d).
    Pursuant to this authority, the Service has promulgated a
    regulation extending the general import prohibition on
    endangered species to threatened species. See 
    50 C.F.R. § 17.31
    (a). The Service reserved the right, however, to create
    “special rule[s]” regarding threatened species, which “contain
    all the applicable prohibitions and exceptions” regarding
    import of that species. 
    Id.
     § 17.31(c). In other words, “the
    [Service] has, with this regulation, established a regime in
    which the prohibitions established for endangered species are
    extended automatically to all threatened species by a blanket
    rule and then withdrawn as appropriate, by special rule for
    particular species and by permit in particular situations.” Sweet
    Home Chapter of Cmtys. for a Great Or. v. Babbitt, 
    1 F.3d 1
    , 5
    (D.C. Cir. 1993).
    Since 1978, the Service has listed the African elephant as
    a threatened species under the ESA, see Listing of the African
    Elephant as a Threatened Species, 
    43 Fed. Reg. 20,499
    , 20,503
    (May 12, 1978); 
    50 C.F.R. § 17.11
    (h), and maintained a
    Special Rule governing its importation, see 
    50 C.F.R. § 17.40
    (e) (“Special Rule”). In 1992, the Service added a
    7
    provision to the Special Rule providing that sport-hunted
    African elephant trophies may only be imported into the United
    States under certain conditions, including that the Service must
    make “[a] determination . . . that the killing of the trophy animal
    will enhance the survival of the species.” 
    Id.
    § 17.40(e)(6)(i)(B). This means that, in the United States, the
    enhancement finding requirement continues to apply in
    accordance with the Special Rule under the ESA. The 1994
    removal of the enhancement finding requirement from the
    Convention for the issuance of import permits for Appendix I
    species “d[id] not supersede import or export requirements
    pursuant to [the ESA].” 62 Fed. Reg. at 44,633.
    The Service maintains the right to make nation-wide
    enhancement findings sua sponte, “on a periodic basis upon
    receipt of new information on the species’ population or
    management.” Id. Current findings “remain in effect until the
    Service finds, based on new information, that the conditions of
    the special rule are no longer met and has published a notice of
    any change in the Federal Register.” Id.
    Finally, section 9(c)(2) of the ESA provides that “[a]ny
    importation into the United States” of non-endangered,
    Appendix II species such as Zimbabwean elephants “shall,”
    where certain conditions are satisfied, “be presumed to be an
    importation not in violation of any provision of [the ESA] or
    any regulation issued pursuant to [the ESA].” 
    16 U.S.C. § 1538
    (c)(2).
    3. The Enhancement Findings
    In 1997, the Service made a positive enhancement finding
    for sport hunting of African elephants in Zimbabwe.
    Memorandum, Enhancement Finding for African Elephants
    Taken as Sport-hunted Trophies in Zimbabwe, U.S. Fish and
    8
    Wildlife Service (July 2, 1997), reproduced at Joint Appendix
    (“J.A.”) 373–76. The Service explained that revenues
    generated by sport hunting benefited rural communities and
    elephant conservation programs in Zimbabwe. In addition,
    Zimbabwe’s government had in place conservation and anti-
    poaching programs to protect the elephants. And “one of the
    best sets of elephant population data in Africa” indicated that
    Zimbabwe’s elephant population was growing at “about 5%
    per annum,” from 46,000 elephants in 1980 to 66,000 in 1997.
    J.A. 373–74. Thus, “[b]ased on available information,” the
    Service found that “the import of sport-hunted elephant
    trophies from Zimbabwe enhances the survival of the species.”
    J.A. 373.
    Those findings remained in effect until April 4, 2014, when
    the Service made an interim negative enhancement finding and
    suspended the importation of sport-hunted elephant trophies
    from Zimbabwe. Memorandum, Enhancement Finding for
    African Elephants Taken as Sport-hunted Trophies in
    Zimbabwe during 2014, U.S. Fish and Wildlife Service (Apr.
    17, 2014), reproduced at J.A. 496–501. The Service noted that
    publicly available survey information suggested that “the
    elephant population in Zimbabwe has declined from 84,416
    elephants in 2007 to 47,366 elephants in 2012.” J.A. 500. But
    the Service explained that “[t]he most significant aspect of [its]
    analysis is the lack of recent data on what is occurring in
    Zimbabwe.” J.A. 501. The Service had not received any
    information in writing from the Zimbabwean Government
    since 2007, when it had received three undated and unsigned
    papers that relied on dated information. And the Service had
    gained little new information from the occasional meetings it
    had with Zimbabwean officials since 2007. Lacking current
    data from the Zimbabwean government regarding its
    conservation programs and the status of the elephant
    population, the Service determined that it was not possible “to
    9
    make a positive finding that sport-hunting is enhancing the
    survival of the species.” 
    Id.
     It therefore temporarily banned
    imports of sport-hunted trophies of elephants from Zimbabwe
    until better information could be obtained from the
    Zimbabwean government, and sent a letter to authorities in
    Zimbabwe requesting more information. J.A. 468–69.
    The Service announced the negative enhancement finding
    in a press release on its website on April 4, 2014, but did not
    publish notice of the finding in the Federal Register until May
    12, 2014. Interim Suspension of Imports of Elephant Trophies
    from Zimbabwe, 
    79 Fed. Reg. 26,986
     (May 12, 2014). Without
    expressly inviting public comment, the notice stated that the
    Service was “actively pursuing additional information” from
    Zimbabwe and “other sources” to “make a final [enhancement]
    determination” for 2014. 
    Id. at 26,987
    .
    Over the next several months, the Service received and
    considered information submitted by the Zimbabwean
    government, safari outfitters, including Safari Club, and
    conservation and hunting associations. Based on the submitted
    information, the Service issued a final negative enhancement
    finding on July 17, 2014. Memorandum, Enhancement Finding
    for African Elephants Taken as Sport-hunted Trophies in
    Zimbabwe during 2014, U.S. Fish and Wildlife Service (July
    22, 2014), reproduced at J.A. 520–32; see also Notice of
    Suspension of Imports of Zimbabwe Elephant Trophies Taken
    in 2014 on or After April 4, 2014, 
    79 Fed. Reg. 44,459
     (July
    31, 2014). The Service explained that Zimbabwe’s population
    estimates for its elephants were “clearly based on outdated
    information.” J.A. 525. The few recent surveys provided by
    Zimbabwe exhibited a number of faults that rendered them
    prone to double counting. 
    Id.
     The submissions similarly lacked
    reliable information regarding Zimbabwe’s management plans,
    anti-poaching efforts, and regulation of elephant hunting. 
    Id.
     at
    10
    524–28. Unable to make a positive enhancement finding on the
    basis of the new information, the Service forbid the importation
    of elephants harvested in Zimbabwe from April 4, 2014
    through the end of the year.
    On March 26, 2015, the Service made yet another negative
    enhancement finding, banning the importation of trophies of
    “elephants taken in Zimbabwe during the 2015 hunting season
    and future hunting seasons.” Memorandum, Enhancement
    Finding for African Elephants Taken as Sport-hunted Trophies
    in Zimbabwe On or After January 1, 2015, U.S. Fish and
    Wildlife Service (Mar. 26, 2015), reproduced at J.A. 588–605;
    
    id. at 588
    ; see also Notice of Continued Suspension of Imports
    of Zimbabwe Elephant Trophies Taken On or After April 4,
    2014, 
    80 Fed. Reg. 42,524
     (July 17, 2015). Once again, the
    finding was “due to the Service being unable to make [a
    positive] enhancement finding even after receiving additional
    materials from Zimbabwe’s Parks and Wildlife Management
    Authority and others,” including Safari Club. 80 Fed. Reg. at
    42,525.
    B.    Procedural Background
    On April 21, 2014, Safari Club, later joined by the NRA,
    filed a complaint in the District Court, challenging the
    Service’s April 4, 2014 enhancement finding pertaining to
    importation of African elephant trophies from both Zimbabwe
    and Tanzania. Safari Club Int’l v. Jewell, 
    47 F. Supp. 3d 29
    , 31
    (D.D.C. 2014). The District Court granted the federal
    defendants’ motion to dismiss the Tanzanian claims on the
    grounds that the plaintiffs had not exhausted their
    administrative remedies, since no member of the Safari Club or
    NRA had applied for an import permit for any Tanzanian
    elephant. Safari Club Int’l v. Jewell, 
    76 F. Supp. 3d 198
    , 206–
    09 (D.D.C. 2014). The court also allowed the plaintiffs to
    11
    amend their complaint to add claims challenging the July 2014
    enhancement finding. 
    Id.
     at 205–06. The Court of Appeals
    reversed the dismissal of the Tanzanian claims, holding that
    Safari Club and the NRA had standing, the April and July
    findings were final agency actions, and Safari Club did not
    need to seek a permit in order to exhaust its administrative
    remedies. Safari Club Int’l v. Jewell, 
    842 F.3d 1280
    , 1285–90
    (D.C. Cir. 2016).
    In June 2015, Safari Club and the NRA (“Appellants”) filed
    a separate action alleging that the Service’s March 26, 2015
    enhancement finding violated the ESA, 
    16 U.S.C. § 1531
     et
    seq., and the APA, 
    5 U.S.C. § 706
    . Complaint for Declarative
    and Injunctive Relief, ¶¶ 88–125 (June 30, 2015); see also
    Safari Club Int’l v. Jewell, 
    213 F. Supp. 3d 48
    , 51 (D.D.C.
    2016). Members of both organizations had harvested elephants
    in Zimbabwe in 2014 and 2015. However, as a result of the
    challenged enhancement findings, the members were barred
    from importing the trophies into the United States. Complaint,
    ¶¶ 18, 24; Appellants’ Br. 57–58. The District Court
    consolidated the two Zimbabwe-related cases and granted
    leave to Friends of Animals and the Zimbabwe Conservation
    Task Force to intervene as defendants. That consolidated case
    is the subject of this appeal.
    The plaintiffs made four principal ESA and APA claims
    before the District Court. First, they claimed that the Service’s
    reasoning was arbitrary and capricious, in part because the
    findings imposed a standard greater than “enhancement.”
    Second, they argued that by resting on the absence of evidence
    that sport hunting enhances the survival of the African elephant
    in Zimbabwe, the findings violated the presumption of legality
    established in section 9(c)(2) of the ESA. Third, they claimed
    that the removal of the enhancement-finding requirement from
    the Convention in 1994 required the Service to initiate rule
    12
    making with respect to the Special Rule’s enhancement
    condition. Finally, the plaintiffs contended that the three
    enhancement findings were rules subject to notice-and-
    comment rule-making procedures under § 553 of the APA. See
    Safari Club, 213 F. Supp. 3d at 61.
    Safari Club and the NRA moved for summary judgment on
    February 18, 2016. The Service and intervenors opposed that
    motion and cross-moved for summary judgment in their favor.
    On September 30, 2016, the District Court entered
    summary judgment for the government on every claim but one,
    which the Service has not appealed. Safari Club, 213 F. Supp.
    3d at 51. The court held that (1) none of the three findings were
    arbitrary and capricious, id. at 73–81; (2) it was reasonable for
    the Service “to interpret the Special Rule as rebutting [section
    9(c)(2) of the ESA’s] statutory presumption,” id. at 66; (3) the
    Service was not required to initiate rule-making proceedings
    under the ESA when the enhancement condition was removed
    from CITES in 1994, id. at 66–67; and (4) the enhancement
    findings resulted from adjudications and therefore were not
    subject to the APA’s rule-making requirements, id. at 62–64.
    Safari Club and the NRA have now appealed the denial of
    their motion for summary judgment and the entry of judgment
    for Appellees.
    II. ANALYSIS
    A. Standard of Review
    “We review an order granting summary judgment de novo,
    viewing the evidence and drawing all reasonable inferences in
    favor of the nonmoving party.” Chenari v. George Washington
    Univ., 
    847 F.3d 740
    , 744 (D.C. Cir. 2017). “In a case like the
    13
    instant one, in which the District Court reviewed an agency
    action under the APA, we review the administrative action
    directly, according no particular deference to the judgment of
    the District Court.” Holland v. Nat’l Mining Ass’n, 
    309 F.3d 808
    , 814 (D.C. Cir. 2002).
    The APA requires that we “hold unlawful and set aside
    agency action” that is “arbitrary, capricious, an abuse of
    discretion, or otherwise not in accordance with law.” 
    5 U.S.C. § 706
    (2)(A). A disputed action also may be set aside as
    arbitrary and capricious if the agency has acted “without
    observance of procedure required by law.” 
    Id.
     § 706(2)(D); see
    Meister v. U.S. Dep’t of Agric., 
    623 F.3d 363
    , 371 (6th Cir.
    2010) (noting that “even in cases arising under § 706(2)(D), the
    arbitrary-and-capricious standard frequently governs”). In
    applying the arbitrary and capricious standard, we consider
    whether the agency “has relied on factors which Congress has
    not intended it to consider, entirely failed to consider an
    important aspect of the problem, [or] offered an explanation for
    its decision that runs counter to the evidence before the
    agency.” Motor Vehicle Mfrs. Ass’n v. State Farm Mut. Auto.
    Ins. Co., 
    463 U.S. 29
    , 43 (1983). The court may “not . . .
    substitute its [own] judgment for that of the agency,” 
    id.,
     and
    deference is especially warranted where the decision at issue
    “requires a high level of technical expertise,” Marsh v. Or. Nat.
    Res. Council, 
    490 U.S. 360
    , 377 (1989). Nonetheless, we must
    determine whether the Service “examine[d] the relevant data
    and articulate[d] a . . . rational connection between the facts
    found and the choice made.” State Farm, 
    463 U.S. at 43

    The APA also provides that a reviewing court shall “hold
    unlawful and set aside agency action, findings, and conclusions
    found to be . . . in excess of statutory jurisdiction, authority, or
    limitations, or short of statutory right.”

    In considering whether an agency’s construction of its
    authorizing statute is permissible, we apply “the ordinary tools
    of statutory construction” to “determine ‘whether Congress has
    directly spoken to the precise question at issue.’” City of
    Arlington v. FCC, 
    569 U.S. 290
    , 296 (2013) (quoting Chevron

    467 U.S. 837
    , 842
    (1984)). “If the intent of Congress is clear, that is the end of the
    matter; for the court, as well as the agency, must give effect to
    the unambiguously expressed intent of Congress.” Chevron,
    
    467 U.S. at
    842–43. If the statute is ambiguous and the agency
    has acted pursuant to congressionally delegated authority to
    make law and with the intent to act with the force of law, we
    will defer to the agency construction so long as it is reasonable.

    533 U.S. 218

    statutory text forecloses the agency’s assertion of authority, or
    not.” City of Arlington, 569 U.S. at 301.
    Finally, “[w]e must give substantial deference to an
    agency’s interpretation of its own regulations. Our task is not
    to decide which among several competing interpretations best
    serves the regulatory purpose. Rather, the agency’s
    interpretation must be given controlling weight unless it is
    plainly erroneous or inconsistent with the regulation.”

    , 1082
    (D.C. Cir. 2004) (quoting Thomas Jefferson Univ. v. Shalala,
    
    512 U.S. 504
    , 512 (1994)).
    B. The Meaning of “Enhance” in the Service’s
    Regulation
    Appellants first argue that the disputed enhancement
    findings should be overturned because the Service failed to
    apply the correct standard in determining whether to ban
    15
    elephant imports. As noted above, the Special Rule forbids the
    importation of sport-hunted elephant trophies absent a
    “determination” by the Service “that the killing of the trophy
    animal will enhance the survival of the species.” 
    50 C.F.R. § 17.40
    (e)(6)(i)(B) (emphasis added). Appellants claim that the
    Service banned elephant imports on the ground that there was
    no evidence to support findings that sport hunting would
    “ensure” the survival of the elephants. Appellants’ Br. 32–36.
    Appellants thus contend that the Service erred because it
    applied a standard that is more stringent than the “enhance”
    standard in the Service’s regulation.
    Appellants appear to assume that 
    50 C.F.R. § 17.40
    (e)(6)(i)(B) requires the Service to make a positive
    enhancement determination if it finds any potential benefit to
    the survival of elephants from sport hunting. In Appellants’
    view, it does not matter whether the benefits of sport hunting
    are outweighed by its risks to the threatened species. Thus,
    according to Appellants, the Service was obliged to make a
    positive enhancement finding once it found that there were
    some benefits from hunting.
    In particular, Appellants argue that it was error for the
    Service to consider whether the overall elephant population had
    declined, and to take into account non-sport-hunting related
    threats to the elephants, such as poaching. Appellants consider
    these matters irrelevant with respect to whether sport hunting
    will “mak[e] the situation better” for elephants than the absence
    of hunting. Appellants’ Reply Br. 3; see Appellants’ Br. 34.
    Appellants also point out that in both the July 2014 and March
    2015 findings, the Service acknowledged that “scattered
    around Zimbabwe” are “‘bright spots’ of elephant conservation
    efforts,” but concluded that “there are not enough of these
    ‘bright spots’ to overcome the problems currently facing
    Zimbabwe elephant populations and to support a finding that
    16
    sport hunting is enhancing the survival of the species.” J.A.
    532, 605. Appellants insist that requiring conservation efforts
    to “overcome” threats to the elephants amounts to a
    requirement that sport hunting guarantee, not merely
    “enhance,” elephant survival. Appellants’ position is specious.
    The Service reasonably interpreted the Special Rule to
    require a holistic inquiry into whether hunting enhances the
    species’ survival on net, taking into account the sustainability
    of the existing elephant population in light of the obvious
    detriments hunting poses to elephant survival. As the Service
    explained in its March 2015 finding, the enhancement
    determinations, among other things, “look[] to determine [1] if
    a country has sufficient numbers of elephants to support a
    hunting program, [2] if the country has a management plan and
    adequate laws and regulations to effectively implement a
    hunting program, and [3] if the participation of U.S. hunters in
    the program provides a clear benefit to the species to meet the
    [Special Rule’s] requirements for . . . import.” J.A. 589.
    Appellants would have the Service focus exclusively on the last
    consideration – the benefits of hunting – in isolation from
    information about the viability of the elephant population being
    hunted and Zimbabwe’s ability to regulate the hunting
    program.
    Nothing in the Special Rule supports Appellants’ reading
    of “enhance.” The sustainability of Zimbabwe’s elephant
    population and the status of the government’s elephant
    management plan bear directly on the effects of hunting on
    elephant survival. For example, one of the Service’s concerns
    is that the current level of offtake from sources other than sport
    hunting, such as poaching, culling, or problem animal control,
    might be higher than appropriate to maintain a healthy
    population of elephants. See, e.g., Memorandum, July 22, 2014
    Enhancement Finding, J.A. 524; see also 80 Fed. Reg. at
    17
    42,526; 79 Fed. Reg. at 44,460. In these circumstances, sport
    hunting might on net decrease the number of elephants in the
    wild if the existing population is simply too sparse to support
    reductions by hunting.
    The Service’s interpretation of its regulation is entirely
    consistent with the definition of “enhance” and perfectly
    reasonable. Appellants define “enhance” as to “heighten,
    increase.” Appellants’ Br. 32 (citing Merriam-Webster.com,
    “Enhance” (Dec. 5, 2017), http://www.merriam-webster.com/
    dictionary/enhance). That definition in no way forecloses the
    Service from requiring hunting to “increase” elephant survival
    on the whole, taking into account the full biological and
    institutional context bearing on the health of the species. The
    Service’s interpretation of its Special Rule easily passes muster
    under the applicable standard of review. See Thomas Jefferson
    Univ., 
    512 U.S. at 512
     (holding that “the agency’s
    interpretation must be given controlling weight unless it is
    plainly erroneous or inconsistent with the regulation”).
    C. Appellants’ Claim that the Enhancement Findings
    Are Foreclosed by Section 9(c)(2) of the ESA
    Appellants additionally argue that the Service’s negative
    enhancement findings are improper because they rest on the
    absence of evidence that sport hunting enhances the survival of
    the species, rather than on an affirmative finding that sport
    hunting fails to enhance the survival of the African elephant in
    Zimbabwe. Appellants assert that the Service’s approach is
    based on an impermissible construction of the ESA because
    section 9(c)(2) of the act provides that “[a]ny importation into
    the United States” of non-endangered, Appendix II species
    “shall” (where certain conditions not at issue here are satisfied)
    “be presumed to be an importation not in violation of any
    provision of [the ESA] or any regulation issued pursuant to [the
    18
    ESA].” 
    16 U.S.C. § 1538
    (c)(2). Given that the Special Rule is
    a “regulation issued pursuant to [the ESA],” 
    id.,
     Appellants
    insist that section 9(c)(2) applies to its terms. Accordingly,
    because the Service found the evidentiary record inadequate to
    make an affirmative determination as to whether sport hunting
    was a net positive for Zimbabwe’s African elephant
    population, Appellants contend that the statutory presumption
    required the Service to authorize importation. We find no merit
    in this claim. We also find that the Service’s interpretation of
    the ESA is reasonable and entitled to deference. See City of
    Arlington, 569 U.S. at 296.
    “To establish a ‘presumption’ is to say that a finding of the
    predicate fact . . . produces a required conclusion in the absence
    of explanation.” St. Mary’s Honor Ctr. v. Hicks, 
    509 U.S. 502
    ,
    506 (1993) (internal quotation marks omitted) (emphasis
    added). Thus, a presumption is generally rebuttable by the
    presentation of contrary evidence. See FED. R. EVID. 301; Tex.
    Dep’t of Cmty. Affairs v. Burdine, 
    450 U.S. 248
    , 254 (1981).
    Indeed, Appellants acknowledge that the presumption is not
    conclusive. See Oral Arg. Recording 1:52–2:09 (“We[, the
    Appellants,] are not arguing . . . that section 9(c)(2) . . . creates
    a conclusive presumption of importability.”).
    In this case, there is no serious dispute over the fact that the
    regulatory criteria for import were not satisfied. Therefore, the
    section 9(c)(2) presumption was overcome by the combination
    of the Special Rule, the administrative record underlying the
    Special Rule, and the fact-finding in this case with respect to
    the current status of Zimbabwe’s elephant population and
    management program. The Special Rule says that “sport-
    hunted trophies may be imported into the United States
    provided . . . [a] determination is made that the killing of the
    trophy animal will enhance the survival of the species.” 
    50 C.F.R. § 17.40
    (e)(6)(i). No such determination was made here.
    19
    Any “presumption” that this precondition was satisfied is easily
    rebutted by the self-evident fact that it was not.
    The principal problem with Appellants’ argument is that it
    mischaracterizes the Special Rule and the Service’s application
    of the rule. The Special Rule does not require the Service to
    affirmatively find that killing the species does not enhance
    species survival in order to ban importation of sport-hunted
    elephant trophies. The Special Rule allows such imports only
    if, among other things, the Service can find that hunting
    enhances survival. Given that an affirmative enhancement
    finding is a regulatory precondition to the lawful importation
    of Zimbabwean elephants, so too, by necessary extension, is an
    adequate evidentiary basis for making such a finding.
    Therefore, the Service’s conclusion that it lacked evidence to
    make a positive enhancement finding, together with the Special
    Rule’s affirmative enhancement condition and the underlying
    administrative record that led to the rule’s adoption, rebuts any
    presumption that the importation of African elephants complies
    with the Special Rule.
    Section 9(c)(2) in no way constrains the Service’s section
    4(d) authority to condition the importation of threatened
    Appendix II species on an affirmative enhancement finding.
    Under section 4(d) of the ESA, the Service “shall issue such
    regulations as [it] deems necessary and advisable to provide for
    the conservation of [threatened] species” and may “prohibit
    with respect to any threatened species any act prohibited . . .
    with respect to endangered species.” 
    16 U.S.C. § 1533
    (d).
    Because the Service may generally bar imports of endangered
    species, see 
    id.
     § 1538(a)(1)(A), it may do the same with
    respect to threatened species under section 4(d), see id.
    § 1533(d). Appellants do not dispute that the promulgation of
    a blanket ban would be permissible and rebut the presumptive
    legality of Zimbabwean elephant imports. If the Service has the
    20
    authority to completely ban imports of African elephants by
    regulation under section 4(d), it logically follows that it has
    authority to allow imports subject to reasonable conditions, as
    provided in the Special Rule. Therefore, even assuming that
    section 9(c)(2) applies to the Special Rule, it merely establishes
    a presumption that the regulation’s conditions have been met,
    absent a finding to the contrary. It does not dictate the content
    of the conditions.
    In fact, Appellants have conceded that the Special Rule’s
    enhancement condition is consistent with section 9(c)(2). At
    oral argument, counsel for Appellants repeatedly disavowed
    any argument that the Service lacked the authority to require a
    positive enhancement finding as a condition of importation of
    African elephant trophies. See Oral Arg. Recording 1:30–2:16
    (“We are not arguing that section 9(c)(2) prevents the Service
    from enacting a special rule under Section 4(d). We are not
    arguing that [section] 9(c)(2) overrides any such special rule.
    We are not arguing that section 9(c)(2) conflicts with section
    4(d) of the ESA. And we are not arguing . . . that section 9(c)(2)
    . . . preempts section 4 or creates a conclusive presumption of
    importability.”); see also id. at 12:25–16:06 ([Question:] “Are
    you saying that the regulation with the elephant rule is unlawful
    under the statute?” [Answer:] “No.”).
    In sum, Appellants do not dispute that the Service has
    authority under the ESA to promulgate regulations that restrict
    the importation of African elephant trophies. The Service has
    chosen to exercise this authority by requiring an affirmative
    demonstration that sport hunting enhances the survival of the
    African elephant as a precondition to import. Even if
    Appellants are correct that the statutory presumption applies to
    this precondition, the presumption has been rebutted by an
    affirmative finding of a lack of evidence of enhancement.
    21
    D. The Removal of the Enhancement Requirement
    from the Convention
    Appellants additionally contend that the 2014 and 2015
    enhancement findings should be overturned on the ground that
    they cannot be squared with the 1994 amendment to the
    Convention. We find no merit in Appellants’ arguments resting
    on this claim.
    As noted above, before 1994, both the Convention and the
    Special Rule required the Service to make an enhancement
    determination before issuing a permit to import the trophy of
    an Appendix I species. See 57 Fed. Reg. at 35,485 (adding the
    enhancement requirement to the Special Rule in 1992). The
    Convention was amended to remove this requirement in 1994.
    However, the United States retained the requirement in its
    African elephant Special Rule issued under the ESA. See 
    50 C.F.R. § 17.40
    (e)(6)(i)(B); 62 Fed. Reg. at 44,633 (explaining
    that the enhancement condition “continue[d] to apply” after
    African elephants were transferred to Appendix II of the
    Convention). Appellants argue that the Special Rule cannot
    stand now that the enhancement requirement has been
    eliminated from the Convention. This claim is meritless.
    First, Appellants allege that the Service “violated [§ 553 of]
    the APA by changing a regulation—retaining an enhancement
    finding requirement although the reason for it disappeared—
    without going through a proper rulemaking process.”
    Appellants’ Br. 52. Appellants are mistaken. The fact that the
    Service continued to apply the enhancement condition after the
    1994 amendment of the Convention did not in any way alter
    the Special Rule.
    Second, Appellants argue that the sole reason the Service
    added the enhancement condition to the Special Rule was to
    22
    comply with the Convention. Appellants’ Br. 54. Thus,
    according to Appellants, once the provision was removed from
    the Convention, the only justification for the Special Rule’s
    enhancement condition disappeared and the agency was
    obligated to explain its continued reliance on the provision.
    Appellants’ view of the Special Rule and its purposes is off
    base.
    One purpose of the enhancement condition was to
    implement the Convention. However, another purpose was to
    promote the conservation of African elephants by authorizing
    only those imports of sport-hunted trophies that enhance
    elephants’ survival. In the preamble to the Special Rule, the
    Service stated that sport hunting “provide[s] financial support
    programs for elephant conservation.” 57 Fed. Reg. at 35,485.
    In response to a comment, the Service explained that the
    Special Rule “supports . . . carefully regulated consumptive
    uses of African elephants” like sport hunting “as mechanisms
    for attaining revenues to enhance elephant and wildlife
    management throughout the African continent.” Id. at 35,476.
    And in 1997, the Service reiterated that the enhancement
    condition “ensure[s]” that each country’s management
    program “is promoting the conservation of the species.” 62
    Fed. Reg. at 44,633. The 1994 amendment of the Convention
    did not change the pro-conservation purpose of the Special
    Rule’s enhancement condition. Therefore, the Service had no
    obligation to reconsider the Special Rule or explain its failure
    to do so.
    Third, “if a significant factual predicate of a prior decision
    . . . has been removed,” an agency may be petitioned to pursue
    rule making to “reconsider” its approach. WWHT, Inc. v. FCC,
    
    656 F.2d 807
    , 819 (D.C. Cir. 1981). However, judicial review
    of an agency’s denial of a petition to initiate rule making “is
    extremely limited and highly deferential.” Massachusetts v.
    23
    EPA, 
    549 U.S. 497
    , 527–28 (2007); see also WildEarth
    Guardians v. EPA, 
    751 F.3d 649
    , 653 (D.C. Cir. 2014); New
    York v. U.S. Nuclear Regulatory Comm’n, 
    589 F.3d 551
    , 554
    (2d Cir. 2009) (citing Massachusetts v. EPA and noting that
    review of a denial of rule making has been said to be “akin to
    non-reviewability” and falls “at the high end of the range of
    deference and an agency refusal is overturned only in the rarest
    and most compelling of circumstances,” “typically involv[ing]
    plain errors of law”).
    In this case, Appellants did not petition the Service to
    pursue rule making, so there is no denial of any such petition
    for the court to review. Furthermore, it is clear that, because
    some of the principal justifications for the Special Rule have
    not changed, the Service had no obligation to act sua sponte to
    revisit the conditions contained in the rule. Indeed, the Special
    Rule is perfectly consistent with section 4(d) of the ESA, which
    authorizes the Service to promulgate rules that are “necessary
    and advisable to provide for the conservation of [threatened]
    species.” 
    16 U.S.C. § 1533
    (d).
    Fourth, Appellants’ reliance on FCC v. Fox Television
    Stations, Inc., 
    556 U.S. 502
     (2009), is misplaced. It is true that
    when an agency changes its position regarding a regulatory
    matter, it must “provide reasoned explanation for its action.”
    
    Id. at 515
    . As noted above, however, the Service did not change
    course when it retained the Special Rule after the Convention
    was amended. The Service was fully within its rights to retain
    its regulatory approach because the Convention expressly
    allows signatories to enforce stricter regulations than provided
    in the treaty. See CITES art. XIV(1)(a), 27 U.S.T. at 1108.
    Finally, if Appellants’ complaint in this case was meant to
    raise a facial challenge to the Special Rule, the challenge comes
    too late. The window to challenge the validity of the regulation
    24
    has long passed. See 
    28 U.S.C. § 2401
    (a) (barring civil claims
    against the United States “unless the complaint is filed within
    six years after the right of action first accrues”); Mendoza v.
    Perez, 
    754 F.3d 1002
    , 1018 (D.C. Cir. 2014); see also Sierra
    Club de Puerto Rico v. EPA, 
    815 F.3d 22
    , 26–28 (D.C. Cir.
    2016) (holding that petitioners’ challenge to the application of
    an old regulation to a new situation was untimely under the
    Clean Air Act, 
    42 U.S.C. § 7607
    (b)(1)).
    E. The Service’s Failure to Engage in Notice-and-
    Comment Rule Making Before Adopting the
    Enhancement Findings
    The APA provides that when an agency proposes to
    promulgate a rule, it must follow the procedures set out in
    
    5 U.S.C. § 553
    . Among other things, the agency must publish
    a notice “of proposed rule making” in the Federal Register.
    
    5 U.S.C. § 553
    (b). It must then “give interested persons an
    opportunity to participate in the rule making through
    submission” of comments, which the agency must consider. 
    Id.
    § 553(c). A final rule must contain a statement of its basis and
    purposes, id., and be published in the Federal Register “not less
    than 30 days before its effective date,” id. § 553(d).
    At oral argument before this court, the Service conceded
    that it did not comply with the requirements of § 553 of the
    APA in issuing its enhancement findings. The Service
    maintained that it was under no obligation to do so, because, as
    the District Court found, the findings were the product of
    informal adjudications and, therefore, not subject to notice-
    and-comment requirements. We disagree. The enhancement
    findings reflect a final rule and, therefore, the Service was
    required to adhere to the notice-and-comment procedures
    under 
    5 U.S.C. § 553
    .
    25
    1. “Rule Making” Versus “Adjudication” Under the
    APA
    When agencies have the statutory authority to engage in
    rule making and adjudication, they have broad discretion to
    choose which route to pursue. NLRB v. Bell Aerospace Co., 
    416 U.S. 267
    , 291–94 (1974); SEC v. Chenery Corp., 
    332 U.S. 194
    ,
    203 (1947). But when an agency chooses to issue a rule, and
    “formal” procedures are not required, it must follow the
    procedures indicated in § 553. NLRB v. Wyman-Gordon Co.,
    
    394 U.S. 759
    , 763–66 (1969) (plurality opinion). An agency
    may not escape the requirements of § 553 by labeling its rule
    an “adjudication.” See, e.g., id.; Nat’l Ass’n of Home Builders
    v. U.S. Army Corps of Eng’rs, 
    417 F.3d 1272
    , 1284–85 (D.C.
    Cir. 2005) (finding that the Corps’ issuance of nationwide
    dredge-and-fill permits was rule making and not adjudication,
    and stating that “‘rules is rules,’ no matter their gloss”);
    Appalachian Power Co. v. EPA, 
    208 F.3d 1015
    , 1024 (D.C.
    Cir. 2000) (“It is well-established that an agency may not
    escape the notice and comment requirements . . . by labeling a
    major substantive legal addition to a rule a mere
    interpretation.”); Thomas v. New York, 
    802 F.2d 1443
    , 1447
    (D.C. Cir. 1986) (explaining that if EPA’s endangerment
    finding was binding, then it was a “rule” that “could not be
    promulgated without notice-and-comment procedures”);
    Batterton v. Marshall, 
    648 F.2d 694
    , 710 (D.C. Cir. 1980)
    (“[W]here, as here, the agency action satisfies the APA’s
    definition of a rule and eludes exemptions to § 553, it is
    procedurally defective unless promulgated with the procedures
    required by law.”).
    The APA defines “rule making” as the “agency process for
    formulating, amending, or repealing a rule.” 
    5 U.S.C. § 551
    (5).
    A “rule” is defined “very broadly,” Sugar Cane Growers Coop.
    of Fla. v. Veneman, 
    289 F.3d 89
    , 95 (D.C. Cir. 2002), to mean
    26
    “the whole or a part of an agency statement of general or
    particular applicability and future effect designed to
    implement, interpret, or prescribe law or policy.” 
    5 U.S.C. § 551
    (4). On the other hand, an “adjudication” is the “agency
    process for the formulation of an order,” 
    id.
     § 551(7), and an
    “order” is “the whole or a part of a final disposition . . . of an
    agency in a matter other than rulemaking but including
    licensing,” id. § 551(6).
    The Supreme Court has explained that “[t]he basic
    distinction between rulemaking and adjudication is illustrated
    by [the] Court’s treatment of two related cases under the Due
    Process Clause of the Fourteenth Amendment.” Fl. E. Coast,
    
    410 U.S. at 244
    . In Londoner v. City and County of Denver,
    
    210 U.S. 373
     (1908), the Court held that it violated the Due
    Process Clause for an agency to tax property that fronted
    particular streets without providing a hearing for the property
    owners. But in Bi-Metallic Inv. Co. v. State Bd. of Equalization,
    
    239 U.S. 441
     (1915), the Court upheld a state agency’s decision
    to increase the valuation of all taxable property in Denver
    without providing any type of hearing for those affected.
    Central to the distinction was that the agency’s action in Bi-
    Metallic was generally applicable to an open class of all Denver
    property owners while Londoner involved a particularized
    order affecting particular owners “in each case upon individual
    grounds.” Bi-Metallic, 
    239 U.S. at 446
    ; see also Fl. E. Coast,
    
    410 U.S. at 245
    .
    Judicial constructions of a “rule” under the APA follow
    these precepts. Two principles stand out. First, most legislative
    rules are generally applicable. E.g., Bell Aerospace, 
    416 U.S. at
    293–94 (characterizing rules as framing “generalized
    standard[s]” and orders as “individual” and “case-by-case”);
    Neustar, Inc. v. FCC, 
    857 F.3d 886
    , 893 (D.C. Cir. 2017)
    (“Rulemaking scenarios generally involve broad applications
    27
    of more general principles rather than case-specific individual
    determinations.”).
    Second, rules generally have only “future effect” while
    adjudications immediately bind parties by retroactively
    applying law to their past actions. E.g., Wyman-Gordon Co.,
    
    394 U.S. at
    763–66 (plurality opinion); see also 
    id.
     at 775–81
    (Harlan, J. and Douglas, J., agreeing with the plurality on this
    point); Bowen v. Georgetown Univ. Hosp., 
    488 U.S. 204
    , 216–
    17 (1988) (Scalia, J., concurring) (stating that the “central
    distinction between rulemaking and adjudication” is that “rules
    have legal consequences only for the future”); Neustar, 857
    F.3d at 895 (stating that while “it may be proper to enter an
    adjudicatory order without retroactive effect,” “adjudication is
    by its nature retroactive”); Catholic Health Initiatives Iowa
    Corp. v. Sebelius, 
    718 F.3d 914
    , 922 (D.C. Cir. 2013) (stating
    that “an adjudication must have retroactive effect, or else it
    would be considered a rulemaking”).
    Thus, in United States v. Florida East Coast Railway Co.,
    
    410 U.S. 224
     (1973), the Supreme Court explained that the
    agency’s action resulted in a rule, not an order, because it was
    “generalized [in] nature” in that it “[was] applicable across the
    board to all of [a class of] common carriers,” and it was
    intended “for prospective application only, rather than [used to]
    adjudicate[e] a particular set of disputed facts.” 
    Id. at 246
    . In
    this case, the 2014 and 2015 enhancement findings had all of
    the qualities of a legislative rule, so the Service was obligated
    to follow the APA’s notice-and-comment procedures before
    promulgating the findings.
    28
    2. The 2014 and 2015 Enhancement Findings Reflect a
    Final Rule
    The disputed enhancement findings in this case applied to
    all potential imports of sport-hunted elephant trophies from
    Zimbabwe, not to any individual parties. See, e.g., April 2014
    Finding, J.A. 501 (“[T]he Service . . . will not allow the import
    of sport-hunted elephant trophies taken in Zimbabwe after
    April 4, 2014.”); July 2014 Finding, J.A. 532 (“[N]o elephants
    harvested during 2014,” except for those harvested before the
    announcement of the temporary suspension on April 4, 2014,
    “may be imported into the United States.”); March 2015
    Finding, J.A. 605 (“[N]o elephants harvested in Zimbabwe on
    or after January 1, 2015 may be imported into the United
    States.”). The findings did not adjudicate any dispute between
    specific parties.
    Furthermore, the Service’s ban on imports was only meant
    to bind hunters in future permitting adjudications and
    enforcement actions, regardless of when they actually
    harvested their elephant trophy. The April 4, 2014 interim
    finding, as revised on April 17, 2014, banned importation of
    sport-hunted elephants from Zimbabwe after the date of the
    finding, April 4, 2014. J.A. 501. The District Court revised the
    effective date of that finding to May 12, 2014, the date notice
    was published in the Federal Register, Safari Club, 213 F.
    Supp. 3d at 73, and the Service has not appealed that decision.
    The July finding, which superseded the April finding, likewise
    applied only to future imports of elephants hunted after April
    4, 2014. J.A. 532. And the March 2015 finding applied to
    “elephants harvested in Zimbabwe on or after January 1,
    2015.” J.A. 605. The latter two findings covered harvests that
    took place several months before the date of the findings, but
    they only banned the importation of sport-hunted elephants
    from Zimbabwe going forward, throughout the rest of the
    29
    relevant year. Those findings were not retroactive because their
    issuance resulted in no immediate legal consequences for any
    specific parties.
    This is not a case in which the agency made its findings in
    the course of denying an application for an import permit, as
    was true in Franks v. Salazar, 
    816 F. Supp. 2d 49
    , 54 (D.D.C.
    2011) and Marcum v. Salazar, 
    810 F. Supp. 2d 56
    , 64 (D.D.C.
    2011), vacated and remanded on other grounds by 
    694 F.3d 123
     (D.C. Cir. 2012). And the Service has not argued that the
    enhancement findings were “licensing” actions. Rather, the
    2014 and 2015 enhancement findings simply established a
    standard binding on the agency – a negative enhancement
    finding and ban on imports – to be applied to future requests to
    import certain sport-hunted elephants, until such time as the
    Service decides to issue a new rule based on different
    information.
    National Biodiesel Board v. EPA, relied on by the Service,
    actually illustrates this point. 
    843 F.3d 1010
    , 1018 (D.C. Cir.
    2016). In that case, the EPA certified that the compliance plan
    of a single entity, an Argentinian association of biofuel
    producers (“CARBIO”), satisfied the EPA’s regulations. See
    
    id.
     at 1013–15. Domestic biofuel producers alleged the EPA’s
    approval of CARBIO’s application was a rule making. We held
    that “EPA’s approval of the . . . plan was a straightforward
    instance of adjudication.” 
    Id.
     at 1017–18. Unlike the findings
    in this case, the application’s approval was highly
    particularized, binding one entity. We emphasized that “[t]he
    approval, by its own terms, applies only to the CARBIO
    program; indeed, [the petitioner] never even suggests that an
    entity other than CARBIO or its producer-members could avail
    itself of the program without making a separate application to
    EPA.” 
    Id. at 1018
    . It would have been a different situation
    entirely had the EPA suddenly issued a press release, without
    30
    any application before it, that bound the agency to approving
    all future certification applications submitted from Argentinian
    biofuel producers.
    Furthermore, the fact that the negative enhancement
    findings applied, and did not change, the enhancement standard
    established in the Special Rule did not make them
    adjudications. The APA’s definition of “rule” includes certain
    statements that “implement” and “interpret” law. 
    5 U.S.C. § 551
    (4). Here, the three findings on review “implement[ed]”
    and “interpret[ed]” the Special Rule’s enhancement
    requirement by issuing negative enhancement determinations
    for African elephants. 
    Id.
     And, of course, they also
    “prescribe[d]” law in the form of enacting new, binding import
    bans. 
    Id.
    The District Court read Safe Extensions, Inc. v. FAA, 
    509 F.3d 593
     (D.C. Cir. 2007) as holding that an agency action
    could be an adjudication in the absence of “a pending matter
    before the agency.” Safari Club, 213 F. Supp. 3d at 63. That
    case involved an arbitrary and capricious challenge to the
    FAA’s imposition of testing requirements on certain
    companies but not others, through the publication of “advisory
    circulars.” Safe Extensions, 
    509 F.3d at 595
    . However, Safe
    Extensions did not consider whether the circulars were rules,
    and if so, whether they were subject to notice and comment.
    The decision is therefore inapposite.
    Finally, the Service claims that any challenges to the April
    finding are moot because the July finding superseded it.
    However, the Service admits it did not engage in notice-and-
    comment rule making for any of the disputed enhancement
    findings, including the July finding. Therefore, the dispute over
    the April finding is not moot.
    31
    3. Harmless Error
    Finally, the Service argues that any error resulting from its
    failure to use notice-and-comment rule making was not
    prejudicial to Appellants. We reject this claim.
    The court’s decision in Sugar Cane Growers Cooperative
    of Florida v. Veneman, 
    289 F.3d 89
     (D.C. Cir. 2002), is
    controlling. That case involved a similar failure to follow
    notice-and-comment procedures. The Department of
    Agriculture (“USDA”) implemented a “payment-in-kind
    program” for sugar in 2001 without proceeding by notice and
    comment. 
    Id.
     at 91–92. In January 2001, before implementing
    the program, the government met with interested persons to
    hear their concerns about the program. 
    Id. at 92
    . Before
    announcing the program, “Department employees had
    approximately a dozen contacts with sugar industry
    representatives regarding the possibility of a 2001 program.”
    
    Id.
     The USDA announced the program by press release and
    subsequently published notice in the Federal Register in
    September of 2001. 
    Id.
     Despite these attempts to provide public
    notice in the Federal Register and solicit comments from
    interested persons, the court held that the failure to conduct
    notice-and-comment rule making was not harmless. 
    Id. at 96
    .
    The court explained that “an utter failure to comply with
    notice and comment cannot be considered harmless if there is
    any uncertainty at all as to the effect of that failure.” 
    Id.
     The
    court went on to reject the notion that complainants must
    indicate “additional considerations they would have raised in a
    comment procedure,” had they been given the opportunity. 
    Id. at 97
    . The court explained:
    Here the government would have us virtually repeal
    section 553’s requirements: if the government could
    32
    skip those procedures, engage in informal
    consultation, and then be protected from judicial
    review unless a petitioner could show a new
    argument—not presented informally—section 553
    obviously would be eviscerated. The government
    could avoid the necessity of publishing a notice of a
    proposed rule and perhaps, most important, would
    not be obliged to set forth a statement of the basis and
    purpose of the rule, which needs to take account of
    the major comments—and often is a major focus of
    judicial review.
    
    Id.
     at 96–97.
    So, too, in this case. The Service insists that it effectively
    complied with § 553 because in May 2014 it published notice
    of its interim finding in the Federal Register. However, that
    notice never invited comment from the public. It merely stated
    that the agency was “actively pursuing additional information”
    from Zimbabwe and “other sources” to “make a final
    determination” for 2014. 79 Fed. Reg. at 26,987. This phrasing
    makes it far from clear that the May notice was soliciting
    comments from all interested parties. Indeed, while Safari Club
    submitted comments, the NRA did not. Nor did the July 2014
    or March 2015 findings invite public comment. Quite to the
    contrary, they presented their negative enhancement findings
    as conclusions at which the Service had already arrived—as the
    culmination, in other words, rather than the initiation, of the
    decisionmaking process. See 79 Fed. Reg. at 44,461 (“[T]he
    Service is unable to make a finding that sport hunting in
    Zimbabwe is enhancing the survival of the species.”); 80 Fed.
    Reg. at 42,524 (“[T]he suspension on the import of sport-
    hunted African elephant trophies taken in Zimbabwe on or after
    April 4, 2014, [will] be continued until further notice.”). On the
    record before us, we hold that Sugar Cane Growers controls.
    33
    Accordingly, we reject the Service’s contention that any error
    was harmless.
    III. CONCLUSION
    For the reasons set forth above, we affirm in part and
    reverse in part. The case will be remanded to the District Court
    with instructions to remand the case to the Service so that it
    may initiate rule making to address enhancement findings for
    the time periods at issue in this case.
    So ordered.
