    ______________________
    Before NEWMAN, CLEVENGER, and TARANTO, Circuit
    Judges.
    CLEVENGER, Circuit Judge.
    Plaintiffs appeal the decision of the Court of Interna-
    tional Trade (“CIT”) affirming the U.S. Department of
    Commerce’s (“Commerce”) final results in the eighth
    administrative review of the antidumping duty order on
    certain frozen warmwater shrimp from India. Apex
    Frozen Foods Private Ltd. v. United States, 
    144 F. Supp. 3d 1308
     (Ct. Int’l Trade 2016); see also Certain Frozen
    Warmwater Shrimp from India, 
    79 Fed. Reg. 51,309
    (Dep’t Commerce Aug. 28, 2014) (final administrative
    review). Using the “average-to-transaction” methodology
    with zeroing, Commerce assessed mandatory respondent
    Devi Fisheries Limited (“Devi”) with a 1.97 percent duty
    for entries between February 1, 2012, and January 31,
    2012. Using a “mixed alternative” methodology, which
    blends both the average-to-transaction and average-to-
    average methodologies, Commerce assessed the second
    mandatory respondent Falcon Marine Exports Lim-
    ited/K.R. Enterprises (“Falcon”) with a 3.01 percent duty
    for the same time period. Non-mandatory respondents
    (including Apex Frozen Foods Private Limited (“Apex”))
    were assessed with a simple-averaged antidumping duty
    of 2.49 percent.
    Plaintiffs include Apex, Devi, Falcon, and other ex-
    porters subject to Commerce’s antidumping duties on
    frozen warmwater shrimp from India (collectively,
    “Apex”). Apex challenges the methodology used by Com-
    merce to calculate the antidumping duties on a number of
    grounds related to Commerce’s decision to use the aver-
    age-to-transaction methodology and zeroing. For the
    reasons that follow, we affirm the CIT’s decision and
    sustain Commerce’s results.
    4          APEX FROZEN FOODS PRIVATE LTD.   v. UNITED STATES
    BACKGROUND
    I
    “Dumping,” in international trade parlance, is a prac-
    tice where international exporters sell goods to the United
    States at prices lower than they are sold in their home
    markets, in order to undercut U.S. domestic sellers and
    carve out market share. To protect domestic industries
    from goods sold at less than “fair value,” Congress enacted
    a statute allowing Commerce to assess remedial “anti-
    dumping duties” on foreign exports. 
    19 U.S.C. § 1673
    ; see
    also Viet I-Mei Frozen Foods Co. v. United States, 
    839 F.3d 1099
    , 1101 (Fed. Cir. 2016) (“The antidumping
    statute provides for the assessment of remedial duties on
    foreign merchandise sold in the United States at less than
    fair market value that materially injures or threatens to
    injure a domestic industry.”).
    “Sales at less than fair value are those sales for which
    the ‘normal value’ (the price a producer charges in its
    home market) exceeds the ‘export price’ (the price of the
    product in the United States) . . . .” Union Steel v. United
    States, 
    713 F.3d 1101
    , 1103 (Fed. Cir. 2013). Commerce
    performs this pricing comparison, and the concomitant
    antidumping duty calculation, using one of three method-
    ologies:
    (1) Average-to-transaction [“A-T”], in which Com-
    merce compares the weighted average of the nor-
    mal values to the export prices (or constructed
    export prices) of individual transactions.
    (2) Average-to-average [“A-A”], in which Com-
    merce compares the weighted average of the nor-
    mal values to the weighted average of the export
    prices (or constructed export prices).
    (3) Transaction-to-transaction [“T-T”], in which
    Commerce compares the normal value of an indi-
    APEX FROZEN FOODS PRIVATE LTD.   v. UNITED STATES          5
    vidual transaction to the export price (or con-
    structed export price) of an individual transaction.
    
    Id.
     (citation omitted).
    Previously, Commerce’s general practice was to use
    the A-T methodology for both investigations and adminis-
    trative reviews. Id. at 1104. With the adoption of the
    Uruguay Rounds Agreement Act in 1995, Congress re-
    quired that the A-A or T-T methods be the presumed
    defaults for investigations, with the A-T method only to be
    used in certain circumstances. Id.; see also 19 U.S.C.
    § 1677f-1(d)(1). Yet “Commerce continued to use average-
    to-transaction comparisons as its general practice in
    administrative reviews,” in the absence of any governing
    statutory authority. Union Steel, 713 F.3d at 1104. Over
    time, Commerce unified its procedures through regula-
    tion, stating, “[i]n an investigation or review, the Secre-
    tary will use the average-to-average method unless the
    Secretary determines another method is appropriate in a
    particular case,” 
    19 C.F.R. § 351.414
    (c)(1) (2012), and
    began applying the investigations statutory framework to
    guide its administrative reviews as well.
    The investigations statute provides that, in general,
    antidumping duties are to be calculated using the A-A
    method—“comparing the weighted average of the normal
    values to the weighted average of the export prices (and
    constructed export prices) for comparable merchandise.” 1
    19 U.S.C. § 1677f-1(d)(1)(A)(i). The statute, however,
    contemplates an exception to this general rule:
    The administering authority may determine
    whether the subject merchandise is being sold in
    the United States at less than fair value by com-
    1    The statute also supports using the T-T method,
    but the parties are in agreement that the T-T method is
    not at issue here. 19 U.S.C. § 1677f-1(d)(1)(A)(ii).
    6          APEX FROZEN FOODS PRIVATE LTD.    v. UNITED STATES
    paring the weighted average of the normal values
    to the export prices (or constructed export prices)
    of individual transactions for comparable mer-
    chandise, if—
    (i) there is a pattern of export prices (or
    constructed export prices) for comparable
    merchandise that differ significantly
    among purchasers, regions, or periods of
    time, and
    (ii) the administering authority explains
    why such differences cannot be taken into
    account using a method described in para-
    graph (1)(A)(i) or (ii).
    19 U.S.C. § 1677f-1(d)(1)(B). In other words, the A-T
    method can be used, provided two preconditions are met:
    (1) a pattern of significant price differences, and (2) an
    inability of the A-A method to “account” for these differ-
    ences.
    The statutory exception exists to address “targeted” or
    “masked” dumping. Union Steel, 713 F.3d at 1104 n.3.
    Under the A-A methodology, sales of low-priced “dumped”
    merchandise would be averaged with (and offset by) sales
    of higher-priced “masking” merchandise, giving the im-
    pression that no dumping was taking place and frustrat-
    ing the antidumping statute’s purpose. See Koyo Seiko
    Co. v. United States, 
    20 F.3d 1156
    , 1159 (Fed. Cir. 1994).
    The A-T method addresses this concern because, “[b]y
    using individual U.S. prices in calculating dumping
    margins, Commerce is able to identify a merchant who
    dumps the product intermittently—sometimes selling
    below the foreign market value and sometimes selling
    above it.” 
    Id.
     The driving rationale behind the statutory
    exception is that targeted dumping is more likely to be
    occurring where there is a “pattern of export prices . . . for
    comparable merchandise that differ significantly among
    purchasers, regions, or periods of time.” See 19 U.S.C.
    APEX FROZEN FOODS PRIVATE LTD.    v. UNITED STATES        7
    § 1677f-1(d)(1)(B); Union Steel, 713 F.3d at 1104 n.3; see
    also H.R. Rep. No. 103-826, pt. 1, at 99 (1994) (“[The
    exception] provides for a comparison of average normal
    values to individual export prices . . . in situations where
    an average-to-average . . . methodology cannot account for
    a pattern of prices that differ significantly among pur-
    chasers, regions, or time periods, i.e., where targeted
    dumping may be occurring.”).
    Commerce also devised the practice of “zeroing” when
    compiling a weighted average dumping margin—“where
    negative dumping margins (i.e., margins of sales of mer-
    chandise sold at nondumped prices) are given a value of
    zero and only positive dumping margins (i.e., margins for
    sales of merchandise sold at dumped prices) are aggregat-
    ed.” Union Steel, 713 F.3d at 1104. Commerce has dis-
    continued its use of zeroing when applying the A-A
    methodology, but zeroing remains part of Commerce’s
    calculus when compiling a weighted average dumping
    margin under the A-T methodology. Id. at 1104–05, 1109
    (“Commerce’s decision to use or not use the zeroing meth-
    odology reasonably reflects unique goals in differing
    comparison methodologies. . . . When examining individu-
    al export transactions, using the average-to-transaction
    comparison methodology, prices are not averaged and
    zeroing reveals masked dumping.”); see also U.S. Steel
    Corp. v. United States, 
    621 F.3d 1351
    , 1363 (Fed. Cir.
    2010).
    II
    Commerce initiated the eighth administrative review
    of its antidumping duty covering frozen warmwater
    shrimp from India (“AR8”) in April 2013—the review
    period covered entries of merchandise that occurred
    between February 1, 2012, and January 31, 2013. Com-
    merce selected Devi and Falcon as mandatory respond-
    ents.
    8          APEX FROZEN FOODS PRIVATE LTD.   v. UNITED STATES
    Commerce published the final results of AR8 in Au-
    gust 2014, along with an Issues and Decision Memoran-
    dum explaining its methodology and results.               By
    regulation, Commerce typically “use[s] the A-A method
    unless the Secretary determines another method appro-
    priate in a particular case.” 
    19 C.F.R. § 351.414
    (c)(1).
    Commerce noted that, despite the statutory silence re-
    garding administrative reviews, the “analysis that has
    been used in [less-than-fair-value] investigations [is]
    instructive for purposes of examining whether to apply an
    alternative comparison in this administrative review.”
    Joint Appendix at 1395. As such, following 19 U.S.C.
    § 1677f-1(d)(1)(B), Commerce considered (1) whether
    Devi’s and Falcon’s sales exhibited a pattern of significant
    price differences among purchasers, regions, or periods of
    time; and (2) whether “such differences can be taken into
    account using” the A-A method.
    Commerce applied a “differential pricing” analysis 2 to
    determine if there was a pattern of significant price
    2    A high-level summary of the differential pricing
    analysis is sufficient for our purposes, as the parties do
    not dispute the use and results on appeal. First, Com-
    merce uses a statistical test referred to as the “Cohen’s d”
    test, “a generally recognized statistical measure of the
    extent of the difference between the mean of a test group
    and the mean of a comparison group.” Joint Appendix at
    1438. The Cohen’s d test yields a coefficient that may be
    situated within fixed thresholds: small, medium, or large.
    “The large threshold provides the strongest indications
    that there is a significant difference between the means of
    the test and comparison groups . . . .” Id. As such, target-
    ed test groups “pass” the Cohen’s d test if they yield
    coefficients equal to or exceeding the “large” threshold.
    Second, Commerce considers the ratio of the sales in
    the targeted groups found to have passed the Cohen’s d
    APEX FROZEN FOODS PRIVATE LTD.   v. UNITED STATES          9
    differences between Devi’s and Falcon’s purchasers,
    regions, or periods of time. 3 Commerce found that 73.3
    percent of Devi’s sales passed the Cohen’s d test (more
    than 66 percent), therefore theoretically warranting the
    use of the A-T methodology on all of Devi’s sales. In
    contrast, Commerce found 65.31 percent of Falcon’s sales
    passed the Cohen’s d test (between 33 and 66 percent),
    therefore theoretically warranting the use of the mixed
    alternative: the A-T methodology for only those sales
    test to the exporter’s total sales. If the “passing” sales
    make up 33 percent or less of the exporter’s total sales,
    the results suggest that an alternative methodology is not
    justified and the traditional A-A methodology for all sales
    is adequate. If the passing sales make up 66 percent or
    greater, the results support the application of the alterna-
    tive A-T methodology to the entirety of the exporter’s
    sales. Finally, if the passing sales make up between 33
    and 66 percent, the results support a “mixed” alternative
    methodology, wherein the A-T methodology is applied
    only to those sales found to have passed the Cohen’s d
    test, but the A-A methodology is still used for sales not
    passing the test.
    3    In previous administrative reviews, Commerce
    applied what was known as the Nails test to assess ex-
    porters’ pricing differences. See Mid Continent Nail Corp.
    v. United States, 
    712 F. Supp. 2d 1370
    , 1376–79 (Ct. Int’l
    Trade 2010); see also Apex Frozen Foods Private Ltd. v.
    United States, No. 15-2085, slip op. at 8 & n.2 (Fed. Cir.
    July 12, 2017) (discussing the Nails test used in Com-
    merce’s seventh administrative review (“AR7”) of certain
    frozen warmwater shrimp from India). Commerce ex-
    plained its reasoning for the change in methodology in
    Differential Pricing Analysis; Request for Comments, 
    79 Fed. Reg. 26,720
     (May 9, 2014). The propriety of Com-
    merce’s change to its differential pricing analysis is not at
    issue on appeal.
    10         APEX FROZEN FOODS PRIVATE LTD.   v. UNITED STATES
    passing the Cohen’s d test, with the A-A methodology
    being applied to the non-passing sales.
    Following the statute, Commerce also determined
    that the A-A methodology could not “account” for the
    patterns of price differences in either Falcon’s or Devi’s
    sales because “the difference[s] in the weighted-average
    dumping margins computed using the A-to-A method and
    the appropriate alternative method [were] meaningful.”
    Joint Appendix at 1389 (footnote omitted); see also 
    id. at 1439
     (“In considering this question, the Department tests
    whether using an alternative method . . . yields a mean-
    ingful difference in the weighted-average dumping margin
    as compared to that resulting from the use of the [A-A]
    method only.”). Specifically, Commerce determined that
    the ultimate margins for Devi and Falcon were zero using
    the A-A methodology, whereas the margins were 1.97
    percent and 3.01 percent, respectively, using the alterna-
    tive methodologies. Commerce therefore adopted its
    preliminary findings that, because the calculated margins
    for both Devi and Falcon “move[d] across the de minimis
    threshold when calculated using the [A-A] method and an
    alternative method,” use of the respective alternative
    methods for each was justified. 
    Id. at 1439
    .
    Consequently, Commerce assessed Devi with a 1.97
    percent antidumping duty, calculated using the A-T
    methodology for all sales; Commerce assessed Falcon with
    a 3.01 percent antidumping duty, calculated using the
    mixed methodology, with the A-T method applied to sales
    passing the Cohen’s d test, and the A-A method applied to
    the remainder. Exporters not selected for individual
    review were assigned the simple average of the two rates:
    2.49 percent.
    Apex filed suit at the CIT, challenging Commerce’s fi-
    nal results. On February 2, 2016, the CIT rejected Apex’s
    claims and sustained the results of AR8 in full. Apex
    Frozen Foods, 
    144 F. Supp. 3d 1308
    . Apex appeals the
    APEX FROZEN FOODS PRIVATE LTD.   v. UNITED STATES        11
    CIT’s decision to this court. Apex contends that Com-
    merce failed to justify sufficiently its conclusion that the
    A-A methodology could not “account” for the observed
    patterns of price differences. Apex also objects to Com-
    merce’s antidumping margin calculation for the “mixed”
    alternative methodology, which was applied to Falcon’s
    sales.
    We have jurisdiction under 28 U.S.C § 1295(a)(5).
    STANDARD OF REVIEW
    We review Commerce’s actions using the same stand-
    ard applied by the CIT. Dongtai Peak Honey Indus. Co. v.
    United States, 
    777 F.3d 1343
    , 1349 (Fed. Cir. 2015). As
    such, we will sustain the agency’s decisions unless they
    are “unsupported by substantial evidence on the record, or
    otherwise not in accordance with law.”          19 U.S.C.
    § 1516a(b)(1)(B)(i). Notwithstanding the CIT’s “unique
    and specialized expertise in trade law,” we review its
    decision de novo. Union Steel, 713 F.3d at 1106; see also
    Novosteel SA v. United States, 
    284 F.3d 1261
    , 1269 (Fed.
    Cir. 2002) (“[W]e also give due respect to the informed
    opinion of the [CIT].” (internal quotation marks omitted)).
    Our review of an agency’s interpretation and imple-
    mentation of a statutory scheme is governed by the Su-
    preme Court’s holding in Chevron, U.S.A., Inc. v. Natural
    Resources Defense Council, Inc., 
    467 U.S. 837
     (1984).
    Under Chevron’s two-part framework, we first ask
    “whether Congress has directly spoken to the precise
    question at issue.” 
    Id. at 842
    . If yes, “that is the end of
    the matter,” and we “must give effect to the unambiguous-
    ly expressed intent of Congress.” 
    Id.
     at 842–43. But, “if
    the statute is silent or ambiguous with respect to the
    specific issue, the question for the court is whether the
    agency’s answer is based on a permissible construction of
    the statute.” 
    Id. at 843
    ; see also Koyo Seiko, 36 F.3d at
    1573 (“In a situation where Congress has not provided
    clear guidance on an issue, Chevron requires us to defer to
    12         APEX FROZEN FOODS PRIVATE LTD.   v. UNITED STATES
    the agency’s interpretation of its own statute as long as
    that interpretation is reasonable.”).
    DISCUSSION
    Apex contends that Commerce unlawfully applied the
    A-T methodology because it failed to explain adequately
    why the price differences identified by the Cohen’s d test
    could not be “taken into account” using the A-A methodol-
    ogy, as required by statute. See 19 U.S.C. § 1677f-
    1(d)(1)(B)(ii). Additionally, assuming it was proper to use
    the mixed alternative methodology for Falcon’s sales,
    Apex objects to Commerce’s ultimate antidumping duty
    calculation under this approach. We address Apex’s
    arguments in turn.
    I
    Apex does not challenge the results of Commerce’s
    application of the Cohen’s d test—sales that illustrate a
    pattern of significant price differences and that therefore
    may be evidence of targeting or masked dumping. Ra-
    ther, Apex contends that Commerce failed to adhere to
    the statute’s requirement that “the administering author-
    ity explains why such differences cannot be taken into
    account using” the A-A methodology. 19 U.S.C. § 1677f-
    1(d)(1)(B)(ii).
    As noted above, Commerce’s justification for why the
    A-A methodology was unable to account for the price
    differences was based on its “meaningful difference” test,
    which simply compared the ultimate antidumping duties
    that would be applied under the A-A methodology versus
    the alternative methodologies—the pure A-T methodology
    for Devi’s sales, and the mixed methodology for Falcon’s
    sales. Because the margins for both Devi and Falcon
    “move[d] across the de minimis threshold”—going from
    below 0.5 percent with the A-A methodology to above 0.5
    percent with the alternative methodologies—Commerce
    concluded that there was a meaningful difference between
    APEX FROZEN FOODS PRIVATE LTD.   v. UNITED STATES        13
    the rates and that using an alternative methodology was
    warranted. 4 Joint Appendix at 1439.
    Apex takes issue with several aspects of Commerce’s
    meaningful difference test as a mechanism for satisfying
    the statute.
    A
    First, Apex challenges Commerce’s use of all sales
    when conducting its meaningful difference analysis for
    Devi and Falcon, instead of only those sales found to have
    passed the Cohen’s d test. Apex argues that including all
    sales is in direct contravention of the statute, which says
    Commerce must explain “why such differences cannot be
    taken into account using” the A-A methodology. See 19
    U.S.C. § 1677f-1(d)(1)(B)(ii) (emphasis added). According
    to Apex, “such differences” refers to the prior subsection’s
    reference to a “pattern of export prices . . . that differ
    significantly among purchasers, regions, or periods of
    time,” i.e., targeted sales. § 1677d-1(d)(1)(B)(i). Apex
    argues that applying the Cohen’s d test yields “two pools
    of sales, one pool of all targeted sales and another pool of
    all non-targeted sales. The [meaningful difference] test
    which follows must then be conducted on ‘such differ-
    ences,’ which in this case are differences related to the
    targeted sales.” Apex Opening Brief at 35. Apex reasons
    that, by using the entirety of Devi’s and Falcon’s sales in
    the meaningful difference analyses, Commerce ran afoul
    of Congress’s statutory directive and that we are obligat-
    ed, under Chevron step one, to reverse. See Chevron, 467
    4    “[Commerce] will treat as de minimis any
    weighted-average dumping margin . . . that is less than
    0.5 percent ad valorem, or the equivalent specific rate.”
    
    19 C.F.R. § 351.106
    (c). In other words, Commerce disre-
    gards antidumping margins that are less than 0.5 per-
    cent.
    14         APEX FROZEN FOODS PRIVATE LTD.   v. UNITED STATES
    U.S. at 842–43 (“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.”).
    We disagree that the statutory language that Apex re-
    lies on decides the “precise question at issue.” See id. at
    842 (emphasis added). Under a plain reading of the
    statute, the use of “such differences” does not, in itself,
    manifest Congress’s intent to dictate how Commerce is to
    make the determination whether the A-A methodology
    can account for potential targeted or masked dumping.
    See id. at 843 n.9 (explaining that courts are to use “tradi-
    tional tools of statutory construction” to determine
    whether “Congress had an intention on the precise ques-
    tion at issue”). Chevron step one asks if Congress has
    already spoken unambiguously on the course of conduct
    the agency is to follow—we are not convinced Congress
    has expressed any intent whatsoever as to the matter at
    hand. Therefore, we reject Apex’s argument that this
    issue may be resolved as a matter of Chevron step one. 5
    “[I]f the statute is silent or ambiguous with respect to
    the specific issue, the question for the court is whether
    the agency’s answer is based on a permissible construc-
    tion of the statute.” Id. at 843. An agency’s reasonable

    of 19 U.S.C. § 1677f-1(d)(1), by its terms, only applies to
    Commerce’s investigations, and not administrative re-
    views. Indeed, § 1677f-1(d)(2) specifically contemplates
    the continued use of the A-T methodology in reviews,
    without elaborating on the appropriate circumstances for
    doing so. As such, although Commerce has elected to
    follow the investigations framework for its reviews as
    well, we will defer to a reasonable agency interpretation,
    given that Congress did not enact the statute to deal with
    the issue we face.

    interpretation “is ‘given controlling weight unless [it is]
    arbitrary, capricious, or manifestly contrary to statute.’ ”
    PSC VSMPO-Avisma Corp. v. United States, 
    688 F.3d 751
    , 763–64 (Fed. Cir. 2012) (alteration in original) (quot-
    ing Chevron, 
    467 U.S. at
    843–44). Apex maintains that,
    even if Congress has not expressly spoken to the question
    before us, Commerce’s implementation of the statutory
    scheme is arbitrary, capricious, and clearly unreasonable
    and should be set aside. See Changzhou Wujin Fine
    Chem. Factory Co. v. United States, 
    701 F.3d 1367
    , 1374
    (Fed. Cir. 2012). We disagree.
    By statute, Commerce must explain why an observed
    pattern of price differences “cannot be taken into account
    using” the A-A methodology.           19 U.S.C. § 1677f-
    1(d)(1)(B)(ii). As already established, the statute is silent
    on how Commerce is to perform this analysis or even
    what it means for the A-A methodology to take “account”
    of price differences. Faced with a broad delegation of
    authority, Commerce devised its meaningful difference
    test, in which antidumping rates—as they would ulti-
    mately be applied for the A-A methodology versus an
    alternative—are compared, across all sales.
    We find Commerce’s provided rationales in support of
    its meaningful difference analysis to be reasonable. First,
    we agree that the difference in the actual antidumping
    rates that would be assessed—below de minimis when
    calculated with the A-A methodology; above de minimis
    when calculated with an alternative methodology—indeed
    informs the question of whether the A-A methodology can
    adequately account for a pattern of significant price
    differences “because A-A masked the dumping that was
    occurring as revealed by the A-T calculated margin.” See
    Apex Frozen Foods, 144 F. Supp. 3d at 1333 n.24; see also
    id. at 1334 (“It is reasonable for Commerce to judge
    whether A-A is able to account for the price differences by
    assessing its ability to do so against all sales, as it would
    16          APEX FROZEN FOODS PRIVATE LTD.   v. UNITED STATES
    ultimately need to be able to do so when calculating the
    dumping margin.”).
    Second, Commerce explained its view that considering
    all sales is actually necessary to achieve the overall aim of
    § 1677f-1(d)(1)(B), which is to address masked dumping.
    Specifically, Commerce stated in its final Issues and
    Decision Memorandum:
    Higher-priced sales and lower-priced sales do not
    operate independently; all sales are relevant to
    the analysis. Higher- or lower-priced sales could
    be dumped or could be masking other dumped
    sales—this is immaterial in the Cohen’s d test and
    the question of whether there is a pattern of pric-
    es that differ significantly, because this analysis
    includes no comparisons with [normal values]. By
    considering all sales, both higher-priced and low-
    er-priced, the Department is able to analyze an
    exporter’s pricing behavior and to identify wheth-
    er there is a pattern of prices that differ signifi-
    cantly. . . . Where the evidence indicates that the
    exporter is engaged in a pricing behavior which
    creates a pattern, there is cause to continue with
    the analysis to determine whether masked dump-
    ing is occurring.
    Joint Appendix at 1412. We understand Apex to be
    challenging Commerce’s position on this point, but we
    cannot say that the methodology Commerce has chosen to
    implement Congress’s statutory scheme is unreasonable,
    even where its justification may be, as the CIT found,
    “less than ideal.” See Apex Frozen Foods, 144 F. Supp. 3d
    at 1333 n.24; see also PSC VSMPO-Avisma, 688 F.3d at
    764 (“This court has recognized that the antidumping
    statute reveals tremendous deference to the expertise of
    the Secretary of Commerce in administering the anti-
    dumping law. Antidumping and countervailing duty
    determinations involve complex economic and accounting
    APEX FROZEN FOODS PRIVATE LTD.   v. UNITED STATES         17
    decisions of a technical nature, for which agencies possess
    far greater expertise than courts.” (quoting Fujitsu Gen.
    Ltd. v. United States, 
    88 F.3d 1034
    , 1039 (Fed. Cir.
    1996))); cf. FCC v. Fox Television Stations, Inc., 
    556 U.S. 502
    , 513–14 (2009) (“[A] court is not to substitute its
    judgment for that of the agency, and should uphold a
    decision of less than ideal clarity if the agency’s path may
    reasonably be discerned.” (internal quotation marks and
    citations omitted)).
    Apex, however, raises two specific counterarguments,
    as to why Commerce’s implementation of the statute is
    unreasonable. According to Apex, the statute contem-
    plates a “two-stage process”: Commerce only needs to
    consider the entirety of an exporter’s sales when ascer-
    taining a pattern of price differences; but when perform-
    ing the meaningful difference analysis, Commerce “need
    not consider all sales again.” Apex Opening Brief at 38.
    Moreover, Apex draws a distinction between the meaning-
    ful difference analysis, which goes to the threshold ques-
    tion of whether an alternative methodology other than
    A-A is appropriate, and the ultimate remedy—i.e., the
    weighted-average antidumping margin calculation.
    Whereas it may be reasonable to consider all sales when
    calculating a final antidumping duty with the A-T meth-
    odology, Apex argues it is not reasonable to do so at the
    threshold “account” stage.
    We see no merit to Apex’s first argument that Com-
    merce, after considering all sales in conducting its “pat-
    tern” analysis, should not consider all sales in its
    meaningful difference analysis. See Apex Opening Brief
    at 38 (“Logically, there is no need to consider ‘all
    sales’ . . . during the second stage . . . .”). To the extent
    Apex is arguing that Commerce’s meaningful difference
    test is unreasonable because it is inconsistent with the
    statute’s text, Apex’s argument rests on an artificially
    rigid reading of the statute that we find unsupported. At
    a minimum, even if Apex presented a plausible interpre-
    18         APEX FROZEN FOODS PRIVATE LTD.   v. UNITED STATES
    tation of the statute, it does not necessarily follow that
    Commerce’s differing interpretation would be unreasona-
    ble or impermissible. See Chevron, 
    467 U.S. at
    843 n.11
    (“The court need not conclude that the agency construc-
    tion was the only one it permissibly could have adopted to
    uphold the construction, or even the reading the court
    would have reached if the question initially had arisen in
    a judicial proceeding.”). And as to whether Commerce
    acted arbitrarily or capriciously, Apex’s own argument
    seems to suggest that, while it did not need to consider all
    sales, Commerce nonetheless could consider them. Thus,
    Apex’s argument fails.
    In addition, despite Apex’s urging to the contrary,
    there is no basis (statutory or otherwise) for demanding a
    distinction between the meaningful difference analysis
    and the ultimate margin calculation. Nowhere is Com-
    merce instructed how to perform a threshold “account”
    determination or that it must be different from the reme-
    dial margin calculation. A meaningful difference test is
    not even required under the statute. And, as we have
    already determined, Commerce has explained why a
    comparison of the ultimate antidumping rates sheds light
    on whether the A-A methodology can account for price
    differences—an explanation the CIT found adequate and
    reasonable, as do we. See Apex Frozen Foods, 144 F.
    Supp. 3d at 1333 n.24 (“The court can discern from Com-
    merce’s explanation that A-A cannot account for the
    pattern of significant price differences because A-A
    masked the dumping that was occurring as revealed by
    the A-T calculated margin. Thus, the meaningful differ-
    ence between the margins demonstrated that A-A is not
    equipped to uncover the mandatory respondents’ dump-
    ing.”).
    We affirm Commerce’s decision to analyze all of Devi’s
    and Falcon’s sales in conducting its meaningful difference
    analysis as a reasonable exercise of its delegated authori-
    ty.
    APEX FROZEN FOODS PRIVATE LTD.   v. UNITED STATES       19
    B
    Second, Apex objects to Commerce’s uneven use of ze-
    roing in its meaningful difference analysis. As already
    noted, when looking at whether there was a meaningful
    difference between the A-A methodology and the A-T
    alternatives, Commerce compared the antidumping
    margins as they would be ultimately calculated in prac-
    tice. Commerce does not use zeroing when applying the
    A-A methodology, but does use zeroing with the A-T
    methodology. See generally Union Steel, 713 F.3d at
    1104–09. Apex contends that, contrary to the goal of the
    statute, “Commerce is simply measuring differences in
    [antidumping] margins caused by zeroing, rather than
    measuring whether A-A can account for masked dumping
    attributed to targeted sales.” Apex Opening Brief at 40.
    Apex repeats many arguments discussed already in the
    context of Commerce’s use of all sales. Apex argues that
    the disparate use of zeroing is contrary to language of the
    statute, which requires Commerce to determine whether
    A-A can account for significant price differences, “not
    differences in calculation methodologies attributable to
    zeroing.” Id. Apex also argues that, regardless of how
    zeroing is applied at the ultimate remedy stage, it should
    be applied evenly at the threshold meaningful difference
    analysis. Finally, Apex contends that, when zeroing is
    used consistently, the differences between the A-A meth-
    odology and the A-T alternatives are “miniscule,” demon-
    strating that there is no meaningful difference between
    the methodologies, except due to the distortive effects of
    zeroing. Apex Opening Brief at 43.
    Much of our analysis from the previous discussion ap-
    plies with equal force to the question now presented. As
    we held before, the statutory text of 19 U.S.C. § 1677f-
    1(d)(1)(B)(ii) does not illustrate a clear Congressional
    directive to Commerce. Certainly it does not demand
    whether Commerce is to use zeroing in any particular
    fashion. Therefore, we merely assess whether Com-
    20         APEX FROZEN FOODS PRIVATE LTD.   v. UNITED STATES
    merce’s reading of the statute was permissible and
    whether its implementation was otherwise arbitrary,
    capricious, or unreasonable. See Chevron, 
    467 U.S. at
    843–44; Koyo Seiko, 36 F.3d at 1573.
    We hold that Commerce’s meaningful difference anal-
    ysis—comparing the ultimate antidumping rates result-
    ing from the A-A methodology, without zeroing; and the
    A-T methodology, with zeroing—was reasonable. Apex
    argues Commerce can only measure masked dumping by
    zeroing on both sides or not at all (“a true ‘apples-to-
    apples’ comparison”). Apex Opening Brief at 48. But, as
    we stated above, nothing in the statute demands invent-
    ing a two-part analysis as Apex suggests—one calculation
    for the meaningful difference test and a different calcula-
    tion for the ultimate remedy. Commerce’s methodology
    compares the A-A and A-T methodologies, as they are
    applied in practice, and in a manner this court has ex-
    pressly condoned. See Union Steel, 713 F.3d at 1109
    (“Commerce’s decision to use or not use the zeroing meth-
    odology reasonably reflects unique goals in differing
    comparison methodologies.”); Apex Frozen Foods, 144 F.
    Supp. 3d at 1335 (“The zeroing characteristic of A-T is
    inextricably linked to the comparison methodology and its
    effect in the meaningful difference analysis does not
    render the approach unreasonable.”). Apex’s proposal for
    the meaningful difference analysis would require artificial
    comparators—either the A-T methodology without zero-
    ing, or the A-A methodology with zeroing. We think, in
    light of Commerce’s contrary practices and our precedent,
    Apex’s preferred approach would provide a skewed per-
    spective. At the very least, we cannot say that Com-
    merce’s meaningful difference analysis is unreasonable—
    intuitively, an analysis that compares the methodologies
    as they would ultimately be applied “makes sense.” See
    Commerce Brief at 48.
    Moreover, like the CIT, we find it immaterial whether
    the A-A and A-T margins would be nearly identical if
    APEX FROZEN FOODS PRIVATE LTD.   v. UNITED STATES        21
    zeroing were applied evenly or not at all. See Apex Frozen
    Foods, 144 F. Supp. 3d at 1335 (“While [Apex] may be
    correct that the A-T and A-A margins would be nearly
    identical if one were to either eliminate zeroing or zero on
    both sides of the comparison, that fact does not present an
    arguable issue . . . .”). The notion that Commerce’s chosen
    methodology is unreasonable because it only measures
    the effects of zeroing is misplaced. Notwithstanding some
    controversy surrounding the use of zeroing, see Union
    Steel, 713 F.3d at 1104, differences revealed by zeroing
    are not inconsequential or to be ignored, as Apex seems to
    suggest. “In [A-A] comparisons, . . . Commerce examines
    average export prices; zeroing is not necessary because
    high prices offset low prices within each averaging group.
    When examining individual export transactions, using the
    [A-T] comparison methodology, prices are not averaged
    and zeroing reveals masked dumping.” Id. at 1109. In
    other words, the effects of zeroing are precisely what 19
    U.S.C. § 1677f-1(d)(1)(B) seeks to address. Apex argues
    that the justifications for zeroing are only relevant to the
    “remedy phase,” but, for the reasons already given, we
    reject a clear division between the “account” analysis and
    the “remedy” calculation.
    While Commerce’s methodology may indeed be “re-
    sults-oriented,” we cannot say that it preordains the use
    of an A-T alternative methodology or that it is unreasona-
    ble. Apex’s submitted approach may offer another rea-
    sonable alternative, but “[w]hen a statute fails to make
    clear ‘any Congressionally mandated procedure or meth-
    odology for assessment of the statutory tests,’ Commerce
    ‘may perform its duties in the way it believes most suita-
    ble.’ ” See JBF RAK LLC v. United States, 
    790 F.3d 1358
    ,
    1363 (Fed. Cir. 2015) (quoting U.S. Steel Grp. v. United
    States, 
    96 F.3d 1352
    , 1362 (Fed. Cir. 1996)). We agree
    that Commerce’s chosen methodology reasonably achieves
    the overarching statutory aim of addressing targeted or
    masked dumping.
    22         APEX FROZEN FOODS PRIVATE LTD.   v. UNITED STATES
    II
    Apex finally argues that, even if Commerce were justi-
    fied in determining that an alternative methodology
    should be applied, Commerce’s calculation of the “mixed”
    antidumping margin for Falcon was flawed.
    As mentioned briefly already, 65.31 percent of Fal-
    con’s sales passed the Cohen’s d test. Consequently,
    following its differential pricing analysis, Commerce
    applied the A-T methodology (with zeroing) to those sales
    passing the test, and the A-A methodology (without
    zeroing) for sales that did not pass, resulting in two
    antidumping margins: an A-T margin and an A-A margin.
    In this case, the A-A margin for Falcon’s sales was nega-
    tive. In order to arrive at a final, weighted-average
    antidumping margin under this mixed alternative meth-
    odology, Commerce aggregated the two margins, but set
    the negative A-A margin to zero, rather than allowing it
    to offset the positive A-T margin. Apex argues that it was
    arbitrary, capricious, or otherwise unreasonable to use
    zeroing a second time, at the aggregation step, after
    already using zeroing to derive the initial A-T antidump-
    ing margin. According to Apex, this practice of “double
    zeroing” defeats the purpose of the mixed alternative
    methodology by undermining the A-A portion, which does
    not use zeroing. Apex contends the use of double zeroing
    resulted in a much higher (two-fold) ultimate antidump-
    ing duty for Falcon’s sales because “significant negative”
    A-A margins were zeroed, rather than offsetting positive
    margins. Apex Opening Brief at 54.
    Critically, Apex has not challenged the mixed alterna-
    tive methodology itself—just Commerce’s chosen means of
    administering it. At first glance, Apex’s complaint is not
    entirely without merit.      Commerce discontinued the
    practice of zeroing in the A-A methodology context. See
    U.S. Steel Corp., 
    621 F.3d 1351
    . Zeroing the negative A-A
    margins would appear to “defeat the purpose” of using the
    APEX FROZEN FOODS PRIVATE LTD.   v. UNITED STATES       23
    A-A methodology in the mixed calculation at all, as Apex
    suggests. Yet Apex’s solution—that negative margins be
    aggregated with positive margins to offset and dampen
    the final, weighted average antidumping duty—runs into
    a similar paradox, wherein Commerce would effectively
    be performing “double offsetting” and “re-masking”
    masked dumping revealed by the A-T methodology.
    This tension is the result of Commerce’s decision to
    merge the A-A and A-T methodologies into its mixed
    alternative approach. “[T]he [A-A and A-T] comparison
    methodologies compute dumping margins in different
    ways and are used for different reasons.” Union Steel,
    713 F.3d at 1104. It is therefore unsurprising that, in
    seeking to combine the two methodologies to arrive at a
    single antidumping rate, Commerce would be forced to
    subordinate the policy goals of one to the other. As ex-
    plained by the CIT:
    Commerce had the option to aggregate the two
    calculated margins by either providing for or not
    providing for offsets where there was negative
    dumping in the sales subject to A-A. Commerce
    has made the discretionary decision not to provide
    for offsets to calculate the weighted-average
    dumping margin for a respondent whose dumping
    has been assessed using more than one compari-
    son method.
    Apex Frozen Foods, 144 F. Supp. 3d at 1336. It is our role
    merely to assess whether Commerce’s methodological
    choice was reasonable. Like the CIT, we find that it was.
    Having already concluded that the preconditions for
    applying the statutory exceptions were satisfied, 19
    U.S.C. § 1677f-1(d)(1)(B), Commerce chose to maximize
    and preserve the extent of uncovered masked dumping.
    This decision was consistent with the overall statutory
    purpose.
    24          APEX FROZEN FOODS PRIVATE LTD.   v. UNITED STATES
    Apex argues, without citation, that Commerce “was
    arbitrary, capricious, and unreasonable for automatically
    zeroing during the aggregation phase, and without con-
    sideration of the facts and any impact on purported
    ‘masking.’ Commerce must consider the evidence to
    understand the extent of any ‘masking’ on the target-
    ed . . . sales.” Apex Opening Brief at 56. It is not appar-
    ent on what authority Apex rests its challenge to
    Commerce’s methodological choice.           Moreover, Apex
    seems to misunderstand the judiciary’s role when review-
    ing agency action in circumstances such as this. “When a
    challenge to an agency construction of a statutory provi-
    sion, fairly conceptualized, really centers on the wisdom of
    the agency’s policy, rather than whether it is a reasonable
    choice within a gap left open by Congress, the challenge
    must fail. In such a case, federal judges—who have no
    constituency—have a duty to respect legitimate policy
    choices made by those who do.” Chevron, 467 at 866; see
    also PSC VSMPO-Avisma, 688 F.3d at 764 (“In examining
    Commerce’s approach, we must be mindful that as the
    ‘master of antidumping law,’ Commerce is entitled to
    substantial deference in its choice of . . . methodology.”
    (quoting Thai Pineapple Pub. Co. v. United States, 
    187 F.3d 1362
    , 1365 (Fed. Cir. 1999)).
    Commerce’s decision to preserve the maximum
    amount masked dumping by zeroing the negative A-A
    margin was a reasonable exercise of its delegated authori-
    ty, to which we defer.
    CONCLUSION
    For the foregoing reasons, we affirm the decision of
    the CIT, and Commerce’s final results in AR8 are sus-
    tained.
