    2
    WILKINS, Circuit Judge: Orton Motor, Inc. d/b/a Orton’s
    Bagley (“Orton”) is a gas station and convenience store in
    Bagley, Minnesota, that sells cigarettes and tobacco products,
    among other sundries. The Food and Drug Administration
    (“FDA”) levied civil money penalties in the amount of $500
    against Orton following two inspections in which Orton sold
    cigarettes to a minor without first checking identification to
    verify age. As a policy, if a retailer fails an inspection for the
    first time, the FDA’s Center for Tobacco Products (the
    “Center”) charges all violations observed during that
    inspection as a single violation. However, the Center charges
    each separate violation of a regulation as a discrete violation
    during subsequent failed inspections. Accordingly, the FDA
    counted both the sale to a minor and the failure to verify age as
    two separate violations on Orton’s second failed inspection and
    assessed the maximum penalty of $500 for three violations
    within a 24-month period under the civil money penalty
    schedule.
    Orton challenges this determination on two principal
    grounds: that the Tobacco Control Act precludes the FDA’s
    methodology of charging multiple violations in a single
    inspection, and that the FDA violates the law by failing to
    provide a process for retailers to challenge first violations
    before the issuance of a warning letter. We find no merit in
    either contention, and accordingly, we deny Orton’s petition.
    I.
    In 2009, Congress passed the Family Smoking Prevention
    and Tobacco Control Act (“TCA”), which “g[ave] the FDA
    broad regulatory authority over tobacco products, including,
    for instance, authority to impose restrictions on their sale, and
    on the advertising and promotion of such products . . . .”
    Sottera, Inc. v. Food & Drug Admin., 
    627 F.3d 891
    , 898 (D.C.
    3
    Cir. 2010) (citations omitted). The FDA previously attempted
    to regulate tobacco products under the Food, Drug, and
    Cosmetic Act (“FDCA”) in 1996, but the Supreme Court
    concluded in Food & Drug Administration v. Brown &
    Williamson Tobacco Corp. that it lacked the authority to do so
    based on “the FDCA’s overall regulatory scheme and [] the
    tobacco-specific legislation that [Congress] ha[d] enacted
    subsequent to the FDCA.” 
    529 U.S. 120
    , 125-26 (2000).
    Congress passed the TCA to fill this gap, finding that “Federal
    and State governments have lacked the legal and regulatory
    authority and resources they need to address comprehensively
    the public health and societal problems caused by the use of
    tobacco products” and determining that “[i]t is in the public
    interest for Congress to enact legislation that provides the Food
    and Drug Administration with the authority to regulate tobacco
    products and the advertising and promotion of such products.”
    21 U.S.C. § 387 Note, Findings (7) & (12); Pub. L. No. 111-
    31, 123 Stat. 1776 (June 22, 2009). The TCA incorporated this
    authority to regulate tobacco into the existing regulatory
    structure of the FDCA. 
    Sottera, 627 F.3d at 894-95
    .
    Relevant to this case, the TCA prohibits the “misbranding
    of any . . . tobacco product . . . in interstate commerce,” 21
    U.S.C. § 331(b), as well as “the doing of any [] act . . . [that]
    results in [a tobacco product] being . . . misbranded.” 
    Id. § 331(k).
    A tobacco product is “deemed to be misbranded” if
    “it is sold or distributed in violation of regulations prescribed
    under section 387f(d),” 
    id. § 387c(a)(7)(B),
    which in turn
    authorizes the Secretary of Health and Human Services to
    “require restrictions on the sale and distribution of a tobacco
    product” by regulation, as “appropriate for the protection of the
    public health.” 
    Id. § 387f(d).
    The regulations promulgated
    pursuant to this section provide that:
    4
    (1) No retailer may sell cigarettes or smokeless
    tobacco to any person younger than 18 years of
    age;
    (2) (i) Except [through mail-order and in locations
    admitting only adults], each retailer must verify by
    means of photographic identification containing
    the bearer’s date of birth that no person purchasing
    the product is younger than 18 years of age;
    (ii) No such verification is required for any
    person over the age of 26;
    (3) Except as otherwise provided in [regulations
    about self service], a retailer may sell cigarettes or
    smokeless tobacco only in a direct, face-to-face
    exchange without the assistance of any electronic
    or mechanical device (such as a vending machine);
    (4) No retailer may break or otherwise open any
    cigarette or smokeless tobacco package to sell or
    distribute individual cigarettes [or a quantity of
    cigarettes or smokeless tobacco smaller than that
    contained in a manufacturer-distributed package];
    (5) Each retailer must [bring into compliance] all
    self-service displays, advertising, labeling, and
    other items, that are located in the retailer’s
    establishment.
    21 C.F.R. § 1140.14(a). Neither the statute nor the regulations
    explicitly states how violations are to be counted.
    The TCA created civil monetary penalties for violations
    related to tobacco. Section 333 provides for civil money
    penalties “in an amount not to exceed $15,000 for each such
    violation, and not to exceed $1,000,000 for all such violations
    adjudicated in a single proceeding,” with enhanced penalties
    available for intentional violations. 21 U.S.C. § 333(f)(9).
    Other provisions specify the penalty schedule applicable to
    5
    violations of the retailer-specific regulations. For a retailer
    with an approved training program, the maximum penalties
    are:
    (I)     in the case of the first violation, $0.00
    together with the issuance of a warning letter
    to the retailer;
    (II)    in the case of a second violation within a 12-
    month period, $250;
    (III)   in the case of a third violation within a 24-
    month period, $500;
    (IV)    in the case of a fourth violation within a 24-
    month period, $2,000;
    (V)     in the case of a fifth violation within a 36-
    month period, $5,000; and
    (VI)    in the case of a sixth or subsequent violation
    within a 48-month period, $10,000 as
    determined by the Secretary on a case-by-
    case basis.
    21 U.S.C. § 333 Note; Pub. L. No. 111-31, 123 Stat. 1776,
    1839 (June 22, 2009).
    The TCA requires the Secretary of Health and Human
    Services to issue guidance regarding a variety of topics and
    procedures for the assessment of violations and civil money
    penalties. Codified at 21 U.S.C. § 333, these provisions direct
    that the Secretary issue guidance:
    (B) providing for timely and effective notice . . . to
    the retailer of each alleged violation at a particular
    retail outlet prior to conducting a followup
    compliance check . . . .;
    (C) providing for a hearing pursuant to the
    procedures established through regulations of the
    6
    Food and Drug Administration for assessing civil
    money penalties, including at a retailer’s request a
    hearing by telephone or at the nearest regional or
    field office of the Food and Drug Administration,
    and providing for an expedited procedure for the
    administrative appeal of an alleged violation;
    (D) providing that a person may not be charged
    with a violation at a particular retail outlet unless
    the Secretary has provided notice to the retailer of
    all previous violations at that outlet;
    (E) establishing that civil money penalties for
    multiple violations shall increase from one
    violation to the next violation pursuant to [the
    penalty schedule] within the time periods provided
    for in such [schedule].
    TCA § 103(q)(1); Pub. Law No. 111-31, 123 Stat. 1776, 1838-
    39 (June 22, 2009).
    The Center published two guidance documents explaining
    its approach to enforcement of the tobacco retail regulations.
    One was entitled “Civil Money Penalties and No-Tobacco-Sale
    Orders for Tobacco Retailers” and the other offered
    “Responses to FAQs” about the same. See Ctr. for Tobacco
    Prods., Food & Drug Admin., U.S. Dep’t of Health & Human
    Servs., Civil Money Penalties and No-Tobacco-Sale Orders for
    Tobacco Retailers: Guidance for Industry (“CMP Guidance”)
    (rev. Dec. 2016), available at www.fda.gov/Tobacco
    Products/Labeling/RulesRegulationsGuidance/ucm447308.ht
    m (last visited Mar. 19, 2018); Civil Money Penalties and No-
    Tobacco-Sale Orders for Tobacco Retailers, Responses to
    Frequently Asked Questions (“FAQs”) (rev. Dec. 2016),
    available      at    www.fda.gov/TobaccoProducts/Labeling/
    RulesRegulationsGuidance/ucm252810.htm (last visited Mar.
    19, 2018). The guidance documents bear a banner announcing
    7
    that they are “not binding on FDA or the public.” See CMP
    Guidance at 1; FAQs at 1. Substantively, the guidance sets
    forth the Center’s approach to actions for civil money penalties.
    The CMP Guidance provides significant detail about the
    Center’s enforcement approach, including follow-up visits to
    inspect retailers after violations. The Center’s “FAQ”
    document explains the Center’s enforcement position of
    counting multiple regulation violations on subsequent visits,
    while “count[ing] only one regulation violation from the first
    inspection.” See FAQs, Question 43 at 13 (“[The Center]
    counts only one regulation violation from the first inspection at
    a retail outlet, regardless of the number of regulation violations
    that were noted and included in a Warning Letter. For any
    subsequent inspections, [the Center] may count any or all
    violations and its general policy is to count all of them
    individually.”).
    II.
    The parties do not disagree about the facts underlying this
    dispute. On July 10, 2013, an FDA inspector visited Orton and
    observed that a minor was permitted to purchase cigarettes, in
    violation of then-current 21 C.F.R. § 1140.14(a) (2010), and
    that no one checked the minor’s identification before the
    tobacco sale, in violation of 21 C.F.R. § 1140.14(b)(1) (2010).
    The FDA issued a “Warning Letter” on August 15, 2013,
    documenting these violations and concluding that they “cause
    [Orton’s] cigarettes to be ‘misbranded’” under 21 U.S.C.
    § 387(c).    See Letter from Ann Simoneau, Office of
    Compliance and Enforcement, Center for Tobacco Products
    (Aug. 15, 2013); Joint Appendix (“J.A.”) 1-3. Orton did not
    challenge the issuance of the Warning Letter at that time.
    On May 16, 2015, the FDA again inspected Orton and
    documented the same violations for a second time: the sale of
    8
    tobacco products to a minor and that the minor’s purchase took
    place without Orton checking the minor’s identification to
    verify age. The Center brought an administrative complaint
    against Orton on October 1, 2015, seeking civil money
    penalties of $500. See Admin. Compl. For Civ. Money
    Penalties, Ctr. for Tobacco Prods. v. Orton Motor, Inc. d/b/a
    Orton’s Bagley, FDA Docket No. FDA-2015-H-3414 (Oct. 1,
    2015); J.A. 4-8. This amount derives from the FDA’s
    regulations at 21 C.F.R. § 17.2 (2014), which provided at the
    time for a $500 maximum civil money penalty for “3
    [Violations] within a 24 month period.” 
    Id. at 2.
    Orton
    answered the Complaint with a defense that the statute and
    regulations “do not authorize [the agency] to impose multiple
    violations as a result of one inspection” or “one transaction.”
    See Answer to Admin. Compl., Ctr. for Tobacco Prods. v.
    Orton Motor, Inc. d/b/a Orton’s Bagley, FDA Docket No.
    FDA-2015-H-3414 at 3 (Oct. 30, 2015); J.A. 11-14. Orton
    accordingly argued that the $500 penalty was impermissible
    “because two violations were cited during one inspection” or
    “one transaction.” 
    Id. Orton sought
    a hearing before an
    administrative law judge (“ALJ”). 
    Id. at 1.
    After a prehearing conference and cross-motions for
    summary decision, ALJ Lewis Booker issued a Decision and
    Order concluding that Orton “misbranded a tobacco product on
    May 16, 2015, and will be sanctioned by a civil monetary
    penalty of $0 and a judicial Warning Letter.” FDA Office of
    Admin. Law Judges, Initial Decision and Order, Ctr. for
    Tobacco Prods. v. Orton Motor, Inc. d/b/a Orton’s Bagley,
    FDA Docket No. FDA-2015-H-3414 (Feb. 8, 2016); J.A. 26-
    35. In short, ALJ Booker concluded that both the sale to a
    minor and the failure to check identification resulted in
    “misbranding” under a single statutory provision, and, as such,
    constituted a single violation supporting civil money penalties.
    ALJ Booker held that the July 10, 2013, and May 16, 2015,
    9
    incidents each constituted misbranding but, because they were
    22 months apart, they triggered a $0 penalty. 
    Id. at 5-6.
    The
    ALJ issued his own Warning Letter based on the later violation.
    
    Id. at 7.
    The Center appealed to the Departmental Appeals Board
    (the “Board”). In a decision on June 30, 2016, the Board
    reversed the ALJ’s decision and reinstated the $500 penalty.
    See Final Decision on Review of Administrative Law Judge
    Decision, Ctr. for Tobacco Prods. v. Orton Motor, Inc. d/b/a
    Orton’s Bagley, Docket No. A-16-56 (June 30, 2016); J.A. 40-
    65. The Board reasoned that the agency was interpreting its
    own regulations, justifying deference unless the agency’s
    interpretation was contrary to the regulations’ unambiguous
    meaning. Other portions of the statute demonstrated that
    Congress “knew how to limit the number of violations for
    multiple acts in the course of one transaction” as well as to limit
    “how penalties may be applied,” including by imposing caps
    where multiple violations are “adjudicated in a single
    proceeding.” 
    Id. at 11-12.
    The FDA’s guidance demonstrated
    its approach to “distinct” violations, including that the FDA
    would not count multiple violations in the first inspection, but
    would do so in subsequent visits. 
    Id. at 13-15,
    20. The Board
    further reasoned that the Center’s enforcement policy gave
    effect to the statute’s notice provisions, including through its
    guidance and the availability of hearings when civil money
    penalties are imposed on the basis of prior enforcement. 
    Id. at 18-19.
    The Board re-imposed the $500 penalty as authorized
    under the schedule. 
    Id. at 26.
    Orton petitioned for review.
    III.
    Orton argues that the $500 penalty imposed by the Board
    should be set aside under the Administrate Procedure Act as
    “not in accordance with law.” 5 U.S.C. § 706(2)(A). In
    10
    particular, Orton contends that the TCA does not permit the
    Center’s practice of charging multiple violations arising from
    a single inspection or transaction or the issuance of a warning
    letter for a first violation, without a hearing. Orton’s petition
    thus implicates the consistency between the FDA’s practices
    and the TCA.
    The deference afforded to an agency interpretation of a
    statute “var[ies] with circumstances.” See United States v.
    Mead Corp., 
    533 U.S. 218
    , 228 (2001). An interpretation
    reached through a formal process, including adjudication, will
    ordinarily be reviewed under Chevron. See 
    id. at 230-31.
    In
    this case, however, the interpretation that we now review did
    not originally arise through an FDA adjudication: instead, the
    Center expressed its position in guidance documents, upon
    which the Board in turn relied during the civil money penalty
    proceedings.     Such “interpretations contained in policy
    statements, agency manuals, and enforcement guidelines, all of
    which lack the force of law [] do not warrant Chevron-style
    deference,” and instead “are ‘entitled to respect’ . . . but only
    to the extent that those interpretations have the ‘power to
    persuade.’” Christensen v. Harris Cty., 
    529 U.S. 576
    , 587
    (2000) (quoting Skidmore v. Swift & Co., 
    323 U.S. 134
    , 140
    (1944)). Orton purports to challenge both the Board decision
    and the guidance documents themselves, but we need not
    determine which form of the agency’s interpretation is Orton’s
    primary target: it makes no difference in the result here, since
    our conclusion does not require the valence of Chevron
    deference.
    Under Skidmore, the weight a court affords to an agency
    interpretation “will depend upon the thoroughness evident in
    its consideration, the validity of its reasoning, its consistency
    with earlier and later pronouncements, and all those factors
    which give it power to persuade, if lacking power to control.”
    11

    . Ultimately, a court will uphold an
    agency determination under Skidmore if it is persuasive.
    
    Christensen, 529 U.S. at 587
    . Evaluating the statute “in this
    old-fashioned way,” Fed. Election Comm’n v. Craig for U.S.
    Senate, 
    816 F.3d 829
    , 839 (D.C. Cir. 2016) (quotation marks
    omitted), assessing its text and structure, we conclude that the
    FDA’s interpretation is persuasive. “[W]e need not reach the
    question of Chevron deference if the [agency] interpretation
    satisfies the requirements for Skidmore deference.” Union
    Neighbors United, Inc. v. Jewell, 
    831 F.3d 564
    , 580 (D.C. Cir.
    2016) (citing Brown v. United States, 
    327 F.3d 1198
    , 1205
    (D.C. Cir. 2003) (quotation marks omitted).
    A.
    Orton posits that the TCA precludes the charging of
    multiple violations at one time based on certain procedural
    aspects of the statute as well as the broader legislative context.
    But the statute and the regulatory scheme support the agency’s
    contrary conclusion, which has consistently informed its
    enforcement practices.
    As an initial matter, the statute provides plainly for the
    imposition of civil penalties for violations of the tobacco
    requirements. See 21 U.S.C. § 333(f)(9). Although the statute
    does not expressly permit the charging of multiple violations
    from a single inspection or transaction, the law provides the
    FDA with the authority to impose civil penalties for any
    violations committed, absent such a restriction. The FDA’s
    position that its enforcement authority permits it to impose
    penalties for each violation of the tobacco sale restrictions
    arising during a single inspection or transaction is a persuasive
    interpretation of the plain terms of the statute.
    12
    Orton argues that three procedural provisions combine to
    curtail the FDA’s enforcement authority: the requirement of
    “timely and effective notice . . . to the retailer of each alleged
    violation at a particular retail outlet prior to conducting a
    followup compliance check,” that the FDA enact regulations
    establishing a hearing process and an “expedited procedure for
    the administrative appeal of an alleged violation,” and that “a
    person may not be charged with a violation at a particular retail
    outlet unless the Secretary has provided notice to the retailer of
    all previous violations at that outlet.” See TCA § 103(q). But
    these provisions hardly demand the interpretation that Orton
    advocates. Notice before a “followup compliance check”
    refers to subsequent inspections – by the plain meaning of the
    words, “compliance check” is an event of inspection, not the
    incident of a violation. And “notice . . . of all previous
    violations” does not mean that the Center may not charge
    multiple violations, where the regulations support overlapping
    as well as discrete-but-concurrent violations and where the
    statute expressly contemplates the adjudication of multiple
    violations in a single proceeding, as discussed below. Instead,
    “all previous violations” must mean all violations previous to
    those charged. This conclusion preserves the integrity of the
    statutory scheme and reconciles the provisions within it. See
    James Madison Ltd. v. Ludwig, 
    82 F.3d 1085
    , 1093 (D.C. Cir.
    1996) (noting the Court’s “obligation to interpret the statute’s
    provisions in harmony with each other”); Nat’l Corn Growers
    Ass’n v. EPA, 
    613 F.3d 266
    , 272 (D.C. Cir. 2010) (citing Brown
    & Williamson Tobacco Corp. for the proposition that a “statute
    must be interpreted as a ‘coherent regulatory scheme’ with ‘all
    parts fit into a harmonious whole’”).
    The structure of the regulations promulgated under Section
    387f(d), as directed by 21 U.S.C. § 387c(a)(7)(B), also cuts
    against Orton’s proposed interpretation. First, Orton’s position
    would render regulations superfluous with respect to retailer
    13
    conduct toward underage tobacco purchasers. Generally
    speaking, a retailer who sells a tobacco product to a minor, in
    violation of 21 C.F.R. § 1140.14(a)(1), likely only would do so
    without checking identification first, in violation of 21 C.F.R.
    § 1140.14(a)(2). Understanding these regulations as restricting
    separate conduct and supporting separate violations gives
    meaning to both age-related regulations in such circumstances.
    The distinction between the groups of tobacco purchasers to
    which the regulations relate further suggests that each of these
    regulations has independent significance: the requirement that
    a retailer verify age applies with respect to prospective tobacco
    purchasers up to 26 years old, while the sales restriction relates
    only to would-be purchasers under the age of 18. Accordingly,
    the regulations punish violations of the age-verification
    requirements for any purchaser under age 26, but the
    punishment becomes more severe when the violation also
    results in a minor being permitted to purchase tobacco – the
    concern at the core of the age-related regulations. Moreover,
    setting aside the overlap at issue here, it requires little
    imagination to envision an inspection revealing multiple
    violations of other sale restrictions. Perhaps a retailer sells a
    loose cigarette to a 25-year-old, without checking
    identification, violating 21 C.F.R. § 1140.14(a)(4) and (2). Or
    maybe a store offers loose cigarettes in a self-service vending
    machine, despite having no age restrictions on entry to that
    location, violating 21 C.F.R. § 1140.14(a)(4) and (3). If the
    statute counted single and multiple violations identically for
    purposes of the civil money penalties that may attach, the
    incentive for retailers to comply with each of the regulations
    would diminish.
    When examining the varied, potentially overlapping
    conduct covered by these regulations, it merits note that the
    regulations themselves have a special history. Ordinarily,
    reliance on regulations to interpret the authorizing statute
    14
    would be misplaced. See Decker v. Nw. Envtl. Def. Ctr., 
    568 U.S. 597
    , 609 (2013) (“[R]egulations, in order to be valid, must
    be consistent with the statute under which they are
    promulgated.” (quoting United States v. Larionoff, 
    431 U.S. 864
    , 873 (1977)). But the regulations at issue here are unique
    because Congress in the TCA directed the agency to
    promulgate “identical” regulations to those promulgated by the
    Secretary of Health and Human Services in 1996, which were
    part of the prior regulatory regime that the Supreme Court
    struck down in Brown & Williamson. See 21 U.S.C.
    § 387a-1(a)(2). Cf. Regulations Restricting the Sale and
    Distribution of Cigarettes and Smokeless Tobacco to Protect
    Children and Adolescents, 61 Fed. Reg. 44,396-01, § 897.14
    (Aug. 28, 1996). Evidently, Congress legislated with these
    restrictions in mind. See Merrill Lynch, Pierce, Fenner &
    Smith, Inc. v. Curran, 
    456 U.S. 353
    , 381-82 & n.66 (1982) (“re-
    enact[ing] a statute without change” or “incorporating sections
    of a prior law” demonstrate congressional intent to “le[ave]
    intact” contemporary interpretations); cf. Pub. Citizen, Inc. v.
    U.S. Dep’t of Health & Human Servs., 
    332 F.3d 654
    , 669 (D.C.
    Cir. 2003) (declining to rely on congressional ratification
    canon of interpretation where “no formal regulation addressed
    the question”). With these regulations in place at the direction
    of Congress, the statute is easily understood to permit multiple
    violations where multiple regulations were breached.
    Structural characteristics of the statute confirm the
    strength of the FDA’s interpretation and provide further reason
    to find it persuasive. The TCA recognizes the adjudication of
    multiple violations within a single proceeding where it caps
    civil money penalty liability for tobacco control “for all such
    violations adjudicated in a single proceeding.” 21 U.S.C.
    § 333(f)(9). The reference to “violations” in the plural form
    demonstrates that a single proceeding may involve the
    simultaneous adjudication of more than one violation.
    15
    Orton asserts that the inclusion of this language in the
    section governing tobacco civil money penalties generally, but
    not within the provisions setting forth the specific procedures
    for retailers, indicates Congress’s intention that multiple
    violations be adjudicated in discrete proceedings in the latter.
    Pet’r’s Br. 31-32. However, as Orton concedes in the Reply,
    § 333(f)(9) by its plain terms applies to retailers as well as to
    any other entity doing business regulated by the TCA. Pet’r’s
    Reply Br. 10. Moreover, there is no conflict between
    § 333(f)(9) and the specific procedures for civil money
    penalties against retailers – as noted above, the statute is
    otherwise silent as to whether multiple violations may be
    charged at once. It makes little sense that Congress would
    provide generally for the adjudication of multiple tobacco
    control violations in a single proceeding, but carve out retailers
    from that provision implicitly through a series of other
    procedures – without ever stating such an intention expressly.
    Nothing in the retailer provisions demands such a reading of
    the statute taken as a whole.
    In contrast to the contorted exception that Orton would
    have us imply with respect to tobacco retailers, Congress
    clearly precluded the agency from finding multiple violations
    in a single transaction in other portions of the FDCA. In
    particular, the FDCA provides that “multiple convictions of
    one or more persons arising out of the same event or
    transaction, or a related series of events or transactions, shall
    be considered as one violation” for the purpose of calculating
    civil money penalties with respect to violations of certain
    prescription drug sampling restrictions. 21 U.S.C. § 333(b)(2).
    The absence of such a limitation in the provisions governing
    tobacco violations suggests that multiple violations can arise
    from a single inspection or transaction, based on the
    presumption that “[w]here Congress includes particular
    16
    language in one section of a statute but omits it in another
    section of the same Act . . . Congress acts intentionally and
    purposely in the disparate inclusion or exclusion.” Russello v.
    United States, 
    464 U.S. 16
    , 23 (1983) (citation omitted).
    This principle holds true despite the enactment of the
    FDCA provisions at different times. Courts presume that
    Congress legislates against the backdrop of existing statutes.
    See, e.g., Goodyear Atomic Corp. v. Miller, 
    486 U.S. 174
    , 185
    (1988) (courts “presume that Congress is knowledgeable about
    existing law pertinent to the legislation it enacts”); Jerman v.
    Carlisle, McNellie, Rini, Kramer & Ulrich LPA, 
    559 U.S. 573
    ,
    590 (2010). While that presumption “may be overcome by
    specific language that is a reliable indicator of congressional
    intent,” Arkansas Dairy Co-op Ass’n, Inc. v. U.S. Dep’t of Agr.,
    
    573 F.3d 815
    , 829 (D.C. Cir. 2009) (citation omitted), the TCA
    included no such clear language distinguishing the new tobacco
    provisions from the rest of the FDCA into which they were
    incorporated. Assuming, as we must, that Congress understood
    the statutory framework into which it legislated the TCA, the
    explicit preclusion of multiple violations based on a single
    event of improper prescription drug sampling provides further
    persuasive force in favor of the FDA’s position that the tobacco
    restrictions contain no such charging limitation.
    We finally note that the Skidmore inquiry “consider[s]
    whether the agency has applied its position with consistency”
    as a factor in persuasion. Fed. Express Corp. v. Holowecki,
    
    552 U.S. 389
    , 399 (2008). While not dispositive, variation in
    an agency’s interpretation will “count against” its
    persuasiveness. See Landmark Legal Found. v. IRS, 
    267 F.3d 1132
    , 1137 (D.C. Cir. 2001). Here, the Center’s position shows
    no irregularity. To the contrary, the FDA guidance documents
    upon which the Board relied have been operative since 2013,
    without change to the Center’s violation-counting
    17
    methodology. That the FDA has interpreted the statute
    consistently buttresses our determination that its reading merits
    our respect.
    Accordingly, we deny Orton’s petition with respect to its
    first argument that the FDA’s methodology of counting
    violations is improper.
    B.
    We now turn to Orton’s argument that the FDA violated
    the TCA by not providing a process to challenge an alleged first
    violation prior to issuance of a warning letter. As described
    above, the TCA directed the Secretary to issue guidance
    “providing for a hearing pursuant to the procedures established
    through regulations of the Food and Drug Administration for
    assessing civil money penalties.” TCA § 103(q)(1)(C). The
    FDA’s regulations detail extensive procedures governing such
    hearings. However, the FDA treats first violations as falling
    outside of these civil money penalty procedures, as the penalty
    is $0.00 and a warning letter. Orton argues that this omission
    violates the TCA and Orton’s procedural due process rights.
    We disagree. The consequences from a first violation
    alone do not trigger notice and hearing requirements, either
    under the TCA or principles of procedural due process. The
    TCA requires such procedures only for the assessment of civil
    money penalties, and no such penalty attaches to a first
    violation. TCA § 103(q)(1)(C). While the notice requirement
    attaches to any alleged violation, see 
    id. § 103(q)(1)(B),
    it is
    undisputed that Orton received a warning letter providing
    notice of the violations found during the first inspection. Orton
    does not explain why the warning letter itself is not sufficient
    notice.
    18
    Moreover, this Court has rejected the idea that an FDA
    warning letter itself is a consequence subject to judicial review.
    In Holistic Candlers & Consumers Association v. Food & Drug
    Administration, we explained that FDA warning letters, while
    potentially significant as bases for later enforcement, are not
    subject to review where “no legal consequences flow from the
    agency’s conduct to [that point].” 
    664 F.3d 940
    , 944-45 (D.C.
    Cir. 2012) (citation omitted). The lack of legal consequences
    distinguishes an FDA warning letter in this context from an
    agency letter representing final agency action. Cf. Rhea Lana,
    Inc. v. Dep’t of Labor, 
    824 F.3d 1023
    , 1030 (D.C. Cir. 2016)
    (warning letter carries legal consequences where its issuance is
    “dispositive” of notice and establishes “willfulness” in a later
    proceeding); Ciba-Geigy Corp. v. EPA, 
    801 F.2d 430
    , 436-37
    (D.C. Cir. 1986) (concluding that an EPA letter constituted
    reviewable agency action where it stated agency policy that
    certain products would be considered misbranded and the
    company would face cancellation of its registration). Because
    the warning letter issued to Orton does not determine Orton’s
    rights or obligations or carry other legal consequences, the
    FDA’s lack of a hearing procedure by which Orton could
    challenge the first violation is not unlawful.
    As for Orton’s constitutional claims, due process is
    required only where government action threatens a deprivation
    of life, liberty, or property. But Orton has failed to show that
    the mere issuance of a warning letter, absent further
    enforcement action, effects any such deprivation.
    “[R]eputation alone, apart from some more tangible interests
    such as employment, is [n]either ‘liberty’ [n]or ‘property’ by
    itself sufficient to invoke the procedural protection of the Due
    Process Clause.” Paul v. Davis, 
    424 U.S. 693
    , 701 (1976); see
    Trifax Corp. v. Dist. of Columbia 
    314 F.3d 641
    , 643-44 (D.C.
    Cir. 2003). Orton has not alleged any such tangible effect here.
    See 
    Trifax, 314 F.3d at 644
    .
    19
    Critically, a retailer has an opportunity to challenge the
    issuance of a first violation upon the later assessment of civil
    money penalties. During oral argument, counsel for the FDA
    clarified that a retailer can challenge the facts underlying a first
    violation during the adjudication of a subsequent violation: if
    a first violation is disproved, it will not be counted against a
    retailer. Oral Arg. at 24:17-28; 31:51-32:07. This is important
    because a first violation becomes legally significant when civil
    money penalties are assessed for violations identified during a
    subsequent failed inspection. At that point, the amount of
    penalty assessed moves up the civil money penalty schedule,
    based on the foundation of the first violation. As the first
    violation affects the amount of penalty assessed later, the
    concrete consequence of the first violation arises at that point.
    The FDA adjudication of the subsequent violation thus
    provides a meaningful opportunity for a retailer to be heard
    regarding the underlying first violation, at the time that the first
    violation carries legally significant effects. Due process
    requires nothing more, and for this reason, we reject Orton’s
    second basis for its petition.

    For the foregoing reasons, we deny Orton’s petition.
