   OPINION AND ORDER

STANCEU, Judge:

In this consolidated action, three plaintiffs challenge the determination (“Final Results”) the International Trade Administration, U.S. Department of Commerce (“Commerce” or the “Department”) issued to conclude the third periodic administrative review of an antidumping duty order on imports of certain activated carbon (the “subject merchandise”) from the People’s Republic of China (“China” or the “PRC”).

I. Background

A The Parties to the Consolidated Action

For the reasons discussed herein, the court will order a remand for reconsideration of certain aspects of the Final Results.

Plaintiff Albemarle is a U.S. importer of subject merchandise. Compl. ¶ 5 (Nov. 18, 2011), ECF No. 6 (“Albemarle Compl.”); Certain Activated Carbon From the People’s Republic of China: Prelim. Results of the Third Antidumping Duty Administrative Review, and Prelim. Rescission in Part, 76 Fed.Reg. 23,978, 23,979 (Apr. 29, 2011) (“Preliminary Results”). During the POR, Albemarle imported activated carbon from plaintiff-intervenor Huahui, a Chinese exporter. Albemarle Compl. ¶ 16; Consent Mot. to Intervene as a Matter of Right as Pl.-Intervenor 1 (Dec. 2, 2011), ECF No. 13 (“Huahui Mot. to Intervene”). Plaintiff Shanxi DMD is also a Chinese exporter of activated carbon. Compl. ¶ 5 (Dec. 5, 2011), ECF No. 9 (Court No. 11-00475) (“Shanxi DMD Compl.”). Plaintiffs GHC and BPAC are producers and/or exporters of subject merchandise, and plaintiff Cherishmet, Inc. is the U.S. importer affiliate of GHC and BPAC. Compl. ¶3 (Nov. 23, 2011), ECF No. 6 (Court No. 11-00468) (“Cherishmet Compl.”).

Defendant-intervenor CCT is a Chinese producer and exporter of activated carbon, and defendant-intervenor CCC, the parent company of CCT, is a domestic activated carbon producer and the petitioner. Consent Mot. to Intervene as of Right 2 (Dec. 6, 2011), ECF No. 18; Mot. for Leave to Intervene as of Right 2 (Dec. 15, 2011), ECF No. 24; Final Results, 76 Fed.Reg. at 67,143.

B. Procedural History

On April 27, 2007, Commerce issued the antidumping order on certain activated carbon from China. Notice of Antidumping Duty Order: Certain Activated Carbon From the People’s Republic of China, 72 Fed.Reg. 20,988 (Apr. 27, 2007). Commerce initiated the third administrative review of that order on May 28, 2010. Initiation of Antidumping & Countervailing Duty Administrative Reviews, 75 Fed. Reg. 29,976 (May 28, 2010).

Commerce published the preliminary results of the review on April 29, 2011 after selecting Jacobi Carbons AB (“Jacobi”) and CCT as the only mandatory respondents, and after identifying India as the primary surrogate country for the purpose of valuing the factors of production (“FOPs”). Preliminary Results, 76 Fed. Reg. at 23,981. Commerce determined a preliminary margin of $0.05 per kilogram for CCT and a preliminary de minimis margin for Jacobi. Id. Commerce also preliminarily assigned a margin of $0.05 per kilogram (“$/kg”) to the unexamined respondents who had demonstrated entitlement to a rate that was separate of that assigned to the PRC entity (the “separate rate” respondents), which included Huahui, Shanxi DMD, BPAC, and GHC. Id.

In the Final Results, issued October 31, 2011, Commerce determined de minimis margins for both mandatory respondents, Jacobi and CCT. Final Results, 76 Fed. Reg. at 67,145. Huahui was assigned a margin of $0.44/kg, the margin Commerce assigned to it in the previous (second) administrative review of the order, while the other separate rate respondents were assigned a margin of $0.28/kg, the rate Commerce assigned to the separate rate respondents in the previous review. Id.

II. Discussion

A. Jurisdiction and Standard of Review

The court exercises jurisdiction under section 201 of the Customs Courts Act of 1980, 28 U.S.C. § 1581(c), pursuant to which the court reviews actions commenced under section 516A of the Tariff Act of 1930 (“Tariff Act”), 19 U.S.C. § 1516a(a)(2)(B)(iii), including an action contesting the Department’s issuance, under section 751 of the Tariff Act, 19 U.S.C. § 1675(a), of the final results of an administrative review of an antidumping duty order. In reviewing the final results, the court will hold unlawful any finding, conclusion, or determination that is not support by substantial evidence on the record or that is otherwise not in accordance with law. See 19 U.S.C. § 1516a(b)(l)(B)(i).

B. Claims Asserted in this Litigation

There are four claims in this consolidated action. First, both Albemarle and Shanxi DMD challenge the Department’s valuation of CCT’s coal-based carbonized materials using Indian Harmonized Tariff Schedule (“Indian HTS”) subheading 4402.90.10, “Coconut Shell Charcoal.” Mem. of P. & A. in Supp. of Rule 56.2 Mot. for J. on the Agency R. by PI. Albemarle Corp. and Intervenor-Pl. Ningxia Huahui Activated Carbon Co., Ltd. 11, 19-23 (May 21, 2012), ECF No. 45 (“Albemarle Rule 56.2 Mem.”); Pl.’s Rule 56.2 Mem. in Support of Mot. for J. upon the Agency R. 2-3 (May 18, 2012), ECF No. 42-2 (“Shanxi DMD Rule 56.2 Mem.”). Second, Albemarle challenges the Department’s valuation of CCT’s “coal and fines” by-products, claiming this valuation is unlawful because it is based on findings unsupported by substantial evidence and, contrary to Department policy, is significantly higher than the Department’s surrogate value for the coal-based carbonized materials. Albemarle Rule 56.2 Mem. 15-18. Third, Albemarle challenges the $0.44/kg margin that Commerce assigned to Huahui in the Final Results, while Shanxi DMD and Cherishmet challenge the Department’s assignment of a $0.28/kg “separate rate” margin to Shanxi DMD, BPAC and GHC, respectively. Albemarle Rule 56.2 Mem. 24-29; Shanxi DMD Rule 56.2 Mem. 8-17; Brief in Supp. of Consol. Pis.’ Rule 56.2 Mot. for J. upon the Agency R. 14-18 (May 18, 2012), ECF No. 44 (“Cherishmet Rule 56.2 Mem.”). Fourth, Shanxi DMD claims that Commerce erred in assigning it a specific, i.e., U.S. dollar per kilogram, assessment and cash deposit rate rather than an ad valorem rate. Shanxi DMD Rule 56.2 Mem. 17-25.

As discussed herein, the court decides that on remand Commerce must reconsider (1) the surrogate values it determined for carbonized materials and coal and fines by-products; (2) the rate it assigned to certain separate-rate respondents who are parties to this litigation; and (3) its decision to use a per-unit rather than an ad valorem rate for the cash deposit and assessment rates applicable to Shanxi DMD.

C. On Remand, Commerce Must Reconsider the Surrogate Values for CCT’s Carbonized Materials and Coal and Fines By-Products

When determining the normal value of subject merchandise from a nonmarket economy country such as China, Commerce, applying section 773(c)(1) of the Tariff Act, ordinarily determines “surrogate” values for “the factors of production utilized in producing the merchandise” and does so “based on the best available information regarding the values of such factors in a market economy country or countries” that Commerce considers appropriate. 19 U.S.C. § 1677b(c)(l). The surrogate values Commerce determined for CCT’s use of coal-based “carbonized material” in producing subject merchandise, and for CCT’s “coal and fines” byproducts derived from processing the coal-based carbonized material, are at issue in this litigation. Defendant has submitted voluntary remand requests under which Commerce would reconsider both surrogate values, which requests CCT opposes. For the reasons discussed below, the court will order Commerce to reconsider both surrogate values.

1. The Surrogate Value for CCT’s Coah Based Carbonized Material

Carbonized material, the principal material used in producing activated carbon, consists of “most any solid material that has a high carbon content,” including “coal, wood, coconut shells, olive stones, and peat.” Certain Activated Carbon from China, Inv. No. 731-TA-11Q3, USITC Pub. 3913, at 1-5 (Apr. 2007) (Final). Coal is the material most commonly used in producing activated carbon in the United States and China. Id.

In the Preliminary Results, Commerce calculated the surrogate value of CCT’s coal-based carbonized material using Global Trade Atlas (“GTA”) import data for Indian HTS subheading 2704.00.90, “Other Cokes of Coal,” which yielded an average unit value (“AUV”) of 13,865.83 Rupees per metric ton (“Rs/MT”). Decision Mem. 14; Mem. from Int’l Trade Specialist to the File 2 (Apr. 22, 2011) (Admin.R.Doc. No. 2138). In the Final Results, Commerce substantially reduced its surrogate value to 3,796.54 Rs/MT, which reflected an AUV Commerce obtained from GTA import data for Indian HTS subheading 4402.90.10, “Coconut Shell Charcoal,” submitted by Jacobi. Letter from Jacobi to the Sec’y of Commerce Ex. 1 (May 19, 2011) (Admin.R.Doc. No. 2164).

Commerce changed its decision in response to comments that mandatory respondent Jacobi, who is not a party to this action, submitted to Commerce in a ease brief. In that brief, Jacobi argued that “[t]he Department should value Jacobi’s use of carbonized materials using coconut shell charcoal classified under HTS 4402.90.10 because ‘other cokes of coal’ is not used to produce activated carbon.” Letter from Jacobi to the Sec’y of Commerce 1 (June 14, 2011) (Admin.R.Doc. No. 2204) (“Jacobi Case Br.”). Citing the Department’s Draft Remand Determination for the first administrative review of the Order, Jacobi argued, further, that “coconut shell charcoal shares similar properties with carbonized material,” namely, “porosity and adsorption,” and that “those similar properties are essential in the production of activated carbon.” Id. at 3-4 (citation omitted).

Agreeing with Jacobi’s argument, Commerce valued both Jacobi’s and CCT’s carbonized materials using import statistics for Indian HTS subheading 4402.90.10 (“Coconut Shell Charcoal”) and the associated AUV of 3,796.54 Rs/MT. Decision Mem. 14. Citing the Department’s Final Remand Redetermination for the first administrative review of the Order, Commerce found that “Other Cokes of Coal” was not specific to substances that are carbonized, and that the subheading for “Coconut Shell Charcoal” is more product-specific because it pertains to a material with properties of adsorption and porosity similar to those of carbonized material and essential in the production of subject merchandise. Id. at 14-15 (citing Final Remand Redetermination in the First Administrative Review 10-11 (July 26, 2011) (Consol. Court No. 09-00524)). Commerce also noted that the coconut shell charcoal import data were contemporaneous with the POR and exclusive of tax and duty, consistent with the Department’s preferences when selecting surrogate values. Id. at 14.

Albemarle and Shanxi DMD claim that the Department’s revised surrogate value cannot be sustained because there is no record evidence to support a finding that the determination was based on the best available information. Albemarle Rule 56.2 Mem. 19-23; Shanxi DMD Rule 56.2 Mem. 2-3.

At oral argument held on December 13, 2012, the court noted that the record as filed by Commerce appeared to lack the evidence on which Commerce relied in determining its surrogate value for carbonized materials, specifically, the evidence on which the Department relied in the Final Remand Redetermination in the First Review. Oral Tr. 87-88 (Dec. 13, 2012), ECF No. 84. Defendant agreed to submit the missing materials, and the court entered an order with dates for that submission and for submission of additional briefing by the parties on the carbonized material surrogate value issue. Order (Dec. 12, 2012), ECF No. 73. Rather than submit additional record materials in accordance with the order, defendant moved for a voluntary remand, under which Commerce would reconsider its surrogate value for CCT’s carbonized material input and also submit the missing record materials. Def. Mot. for a Voluntary Remand 2-3 (Dec. 19, 2012), ECF No. 74. Defendant stated as its reason for requesting a voluntary remand that, the court having ordered the completion of the administrative record, “the proper course of action at this point is for the Government to seek a voluntary remand to place the evidence on the administrative record and for the agency to accept comments from the parties regarding the evidence and to address those comments in a remand.” Id. at 2. Defendant, accordingly, requested that “the Court vacate its December 13, 2012 order to the extent that it requires the agency to supplement the record with the evidence related to the surrogate value for carbonized material,” and that “[i]n the instant proceeding, Commerce [ ] be allowed to place the evidence on the record and consider comments from the parties in the first instance.” Id.

CCT filed a response in opposition to defendant’s voluntary remand motion. Def.-Intervenor Calgon Carbon (Tianjin) Co., Ltd.’s Resp. in Opp’n to Def.’s Mot. for Voluntary Remand (Dec. 20, 2012), ECF No. 75 (“CCT’s Opp’n to Def.’s Mot.”). CCT argued that a voluntary remand on the Department’s valuation of its carbonized materials is inappropriate because the court, by requesting that Commerce supplement the record submitted, “has already fashioned the appropriate procedure to address the carbonized material claims” and “it is not the proper role of this Court to effectively delegate to Commerce to decide, after the fact, whether its contested final decision was supported by substantial evidence.” Id. at 1, 4. CCT also argued that plaintiffs’ claims regarding the surrogate value of CCT’s carbonized material input “should be dismissed on exhaustion grounds pursuant to 28 U.S.C. § 2637(d)” because no party before Commerce commented in opposition to Jacobi’s advocating a change from Indian HTS subheading 2704.00.90, “Other Cokes of Coal,” to Indian HTS subheading 4402.90.10, “Coconut Shell Charcoal,” for valuation of CCT’s carbonized material input. Id. at 2; CCT’s Resp. 15-16.

An agency generally should be allowed a voluntary remand to reconsider its position provided that “the agency’s concern is substantial and legitimate.” SKF USA Inc. v. United States, 254 F.3d 1022, 1028-30 (Fed.Cir.2001). Here, however, the rationale defendant put forth to explain the basis for the Department’s concern is opaque. Reconsideration of the carbonized material surrogate value does not necessarily follow merely from the fact that the agency erred in failing to include in the administrative record submitted to the court the evidence on which it relied. Defendant offers no reason related to the merits of the decision it wants Commerce to have the opportunity to reconsider, nor does defendant provide a convincing explanation of why the order the court issued upon oral argument is not sufficient. That order directed the completion of the record and allowed the parties to submit briefing that may address the additional evidence. In this respect, CCT’s objection to the voluntary remand request has some merit. However, the court finds reasons to order reconsideration of the carbonized material surrogate value despite the shortcomings in defendant’s motion.

Although sparse in its justification, defendant’s motion indicates at least that Commerce desires to reconsider its decision, thus placing CCT in the unfavorable posture of taking a position on a voluntary remand request that is contrary to the current position of defendant United States, the party on whose behalf CCT has intervened. Furthermore, as discussed later in this Opinion and Order, the court sees a need for a remand on the other surrogate value at issue in this case, which pertains to coal and fines by-products. As the court explains, the two surrogate value issues are related with respect to an assertion that the Department has a policy of disfavoring valuations for downstream byproducts that exceed those of the upstream material input.

Finally, the court does not find merit in CCT’s objection grounded in the requirement to exhaust administrative remedies. As CCT concedes, whether and how the exhaustion requirement is applied is a matter for the court’s discretion. CCT’s Resp. 15; 28 U.S.C. § 2637(d) (“the [court] shall, where appropriate, require the exhaustion of administrative remedies.”); Corus Staal BV v. United States, 502 F.3d 1370, 1379-80 (Fed.Cir.2007) (stating that “applying exhaustion principles in trade cases is subject to the discretion of the judge of the Court of International Trade”). Here, the Department’s change in position on the carbonized material surrogate value was announced in the Final Results, after the submission of case briefs. See Decision Mem. 14; 19 C.F.R. § 351.309(c)(2) (requiring a party to submit a case brief “presenting] all arguments that continue in [its] view to be relevant to [the Department’s] final determination or final results”).

2. The Surrogate Value for CCT’s Coal and Fines By-Products

In the Preliminary Results, Commerce determined that CCT was eligible for byproduct offsets for “non-activated by-products, such as pressroom powder and non-activated fines.” Preliminary Results, 76 Fed.Reg. at 23,989. CCT submitted proposed surrogate value information based on Indian HTS data, which Commerce accepted, resulting in a surrogate value for its “coal by-product” of 4,860.88 Rs/MT and a surrogate value for its “fines byproduct” of 11,319.90 Rs/MT. Mem. from Case Analyst to the File 5, Ex. 1 (Apr. 22, 2011) (Admin.R.Doe. No. 2144). No party-having objected to or commented on these determinations, Commerce left these two by-product surrogate values unchanged in the Final Results. Decision Mem. 1-2. As a result, the Decision Memorandum did not address issues pertaining to these surrogate values. Id.

Albemarle claims that the by-product surrogate value determinations are unsupported by substantial evidence and run counter to agency policy “because they result in an unreasonable and inappropriate inversion” in which the downstream by-products are valued considerably higher than the upstream carbonized material. Albemarle Rule 56.2 Mem. 3-4, 15. Pointing to the Department’s revised surrogate value of 3,796.54 Rs/MT for carbonized materials, Albemarle argues that Commerce should correct the value inversion by reverting to Indian HTS subheading 2704.00.90, “Other Cokes of Coal,” with a value of 13,865.83 Rs/MT, to value CCT’s carbonized material input, as was done in the Preliminary Results. Id. at 18. Defendant, while not confessing error, seeks a voluntary remand so that Commerce may reconsider the surrogate values it assigned to CCT’s coal and fines by-products. Def.’s Resp. 19-20.

CCT seeks to raise various arguments against defendant’s request for a voluntary remand and moves for the filing of its brief in opposition. Def.-Intervenor Calgon Carbon (Tianjin) Co., Ltd.’s Mot. for Leave to File Resp. in Opp’n to Def.’s Req. for Voluntary Partial Remand 3 (Sept. 25, 2012), ECF No. 67 (“CCT’s Opp’n to Def.’s Remand Request”). No party having objected to CCT’s motion to file its brief, the court grants CCT’s motion and deems the accompanying brief filed as of September 25, 2012. The court, however, does not agree with the arguments CCT puts forth.

CCT opposes defendant’s remand request on the grounds that (1) Albemarle did not exhaust its administrative remedies on the issue of surrogate values for coal and fines by-products; (2) defendant has offered no reason for requesting a remand; (3) a remand is not warranted unless error is shown; and (4) a voluntary remand would further delay and complicate the court’s proceedings, causing a delay of at least the 60 days for the requested remand and complicating the court’s appellate review “such that the Court likely would have to deal with two different determinations by the Department (the original final results and the remand results).” CCT’s Opp’n to Def.’s Remand Request 2-5. The court is not persuaded by these arguments and will order a remand in response to defendant’s request.

As discussed supra, decisions pertaining to exhaustion of administrative remedies are matters for the court’s discretion. Here, the court does not consider it appropriate to dismiss Albemarle’s challenge to the by-product surrogate values for failure to exhaust. The ground on which Albemarle brings that challenge — a value inversion relative to the value of carbonized material — did not become apparent until issuance of the Final Results, when Commerce announced that it had changed its surrogate value for the carbonized material based on the argument made by Jacobi.

The court also disagrees with CCT’s assertion that defendant offered no reason for seeking a remand. In requesting the remand, defendant stated as follows:

Albemarle and Huahui contend that the surrogate values currently assigned to the coal and fine by-products do not constitute the best information available for these factors of production and that Commerce’s determination runs counter to agency practice. Upon reviewing plaintiffs’ motion and without confessing error, we respectfully request a partial remand for Commerce to reexamine the values assigned to the by-products.

Def.’s Resp. 19-20 (citations omitted). The court reasonably may infer from the quoted language that Commerce wishes to reconsider its surrogate values in light of the arguments put forth by Albemarle, including the argument that the “value inversion” is contrary to the Department’s practice.

CCT’s third argument, that a remand is not appropriate unless error is shown, is not a correct statement of the law. An agency need not confess error to obtain a voluntary remand. SKF, 254 F.3d at 1029.

CCT’s final objection is also without merit. Although a voluntary remand takes some time, it carries the potential of saving time in that it might avoid a remand later in the proceeding. The objection that the voluntary remand would complicate the proceeding by requiring the court to deal with two decisions is not a valid one, as the agency either will reach the same decision on remand that it reached before or it will reach a different one. In either event, only one decision will be before the court.

D. On Remand, Commerce Must Reconsider Its Separate Rate Methodology as Applied to Unexamined Respondents Shanxi DMD and BPAC and GHC

Albemarle challenges the $0.44/kg margin that Commerce assigned to Huahui in the Final Results, which was based on Huahui’s individual rate in the previous (second) administrative review. Albemarle Rule 56.2 Mem. 4. Albemarle argues that “[i]t makes no sense for Commerce to consider older rates to reasonably reflect margins for the current period while at the same time rejecting current rates as not representative of the dumping margins of the separate rate companies.” Albemarle Rule 56.2 Mem. 29.

Both Shanxi DMD and Cherishmet contest the Department’s assignment of a $0.28/kg margin, which was based on the “separate rate” calculated in the second review, to unexamined respondents Shanxi DMD and BPAC and GHC, respectively. Shanxi DMD Rule 56.2 Mem. 2; Cherish-met Rule 56.2 Mem. 2. Shanxi DMD contends that the rate is unreasonable because Commerce “failed to establish why past data is [sic ] more relevant than current data of mandatory respondents.” Shanxi DMD Rule 56.2 Mem. 15. Similarly, Cherishmet challenges the $0.28/kg margin assigned to BPAC and GHC on the ground that “the Department has presented no evidence or reason for diverting from the well-established premise that the Final Results of a proceeding should be based solely on the facts on the record in that proceeding.” Cherishmet Rule 56.2 Mem. 14, 16. Albemarle, Shanxi DMD, and Cherishmet request that the issue be remanded to Commerce so that Commerce may reconsider the margins applied to unexamined respondents Huahui, Shanxi DMD, and BPAC and GHC, respectively.

When Commerce limits the number of individually examined respondents in an administrative review, as it did here, it must establish a rate for the remaining cooperative, but unexamined, respondents who have demonstrated eligibility for a separate rate. The Tariff Act does not address how Commerce must calculate this separate rate. However, in an investigation, section 735(c)(5) of the Tariff Act directs Commerce, initially, to determine the separate rate by weight-averaging the individual rates calculated for the investigated respondents, excluding de minimis or zero rates and rates based on facts available. 19 U.S.C. § 1673d(c)(5)(A). If, pursuant to section 735(c)(5)(A), all individually investigated respondents’ dumping margins are zero, de minimis, or based on facts available, section 735(c)(5)(B) directs Commerce to “use any reasonable method to establish the estimated all others rate for exporters and producers not individually investigated, including averaging the estimated weighted average dumping margins determined for the exporters and producers individually investigated.” Id. § 1673d(c)(5)(B). Because Congress has not given explicit instructions for calculating the separate rate in periodic administrative reviews, Commerce has a measure of discretion in determining what methodology to employ. This discretion is not unlimited, however, and Commerce must “articulate a satisfactory explanation” for its choice of methodology. Yangzhou Bestpak Gifts & Crafts Co., Ltd. v. United States, 716 F.3d 1370, 1378 (Fed.Cir.2013) (“Bestpak”).

In the Preliminary Results, Commerce noted that Huahui, Shanxi DMD, BPAC, and GHC were among eight firms who met the criteria for separate rate status. Preliminary Results, 76 Fed.Reg. at 23,979. Commerce assigned the qualifying separate rate respondents a rate of $0.05/kg based on the rate calculated for CCT. Id. at 23,990. Commerce did not include in the separate rate calculation the de minimis margin assigned to Jacobi. Id. In the Final Results, Commerce assigned a de minimis margin to both Jacobi and CCT. Final Results, 76 Fed.Reg. at 67,145. Commerce assigned Huahui the same margin it determined in the second review, i.e., $0.44/kg, because Huahui was individually examined in that review. Decision Mem. 4, 7. Commerce assigned the separate rate respondents other than Huahui a $0.28/kg margin that also was based on the previous (second) administrative review. Id. at 4-7. This margin was the margin Commerce calculated for the unexamined respondents in the second review, which

Commerce had calculated as a simple average. Id.

Noting that the statute is silent on the method to be employed, the Decision Memorandum submits that the Department’s method of determining a rate for the separate rate respondents (other than Huahui) is “reasonable” because it represents a “contemporaneous examination of individually-reviewed respondents exclusive of zero, de minimis and facts available margins, and reasonably reflects potential dumping margins for the non-selected companies.” Id. at 5. Further, the Decision Memorandum reasons that the Department’s methodology is appropriate because there is no record evidence to determine whether Jacobi and CCT’s pricing behavior in the POR for the third review was representative of that of the separate rate companies. Id.

The court concludes that Commerce must reconsider the margin it assigned to Shanxi DMD, BPAC, and GHC. The $0.28/kg margin was not based on data pertaining to any pricing behavior that occurred in the third POR. Nor was it based on any data pertaining to these respondents; instead, Commerce reverted to a margin it determined in another review for other respondents. This margin does not reflect commercial reality with respect to Shanxi DMD, BPAC, and GHC and is, in that sense, arbitrary. The Department’s statement that this margin is based on a “contemporaneous examination of individually-reviewed respondents exclusive of zero, de minimis and facts available margins, and reasonably reflects potential dumping margins for the non-selected companies,” Decision Mem. 5, is factually incorrect when viewed in the context of the record evidence of the third review. There is nothing “contemporaneous” about the margin, and, having no factual relationship to the pricing behavior of the respondents who received it, the $0.28/kg margin cannot be said to “reasonably reflect potential dumping margins” in the third POR. Moreover, the Department’s decision is not justified by its rationale, as stated in the Decision Memorandum, that that there was no record evidence with which to determine whether Jacobi and CCT’s pricing behavior in the third POR was representative of that of the separate rate companies. There is no record evidence to support a finding or a reasonable inference that the $0.28/kg margin was representative of the separate rate companies’ pricing behavior in the third POR. While the de minimis margins assigned to Jacobi and CCT at least reflect commercial realities prevailing in the pertinent POR, the same cannot be said for the margin Commerce assigned to Shanxi DMD, BPAC, and GHC.

The Department’s overriding purpose in administrating the antidumping laws must be “to calculate dumping margins as accurately as possible.” Bestpak, 716 F.3d at 1379; see also SNR Roulements v. United States, 402 F.3d 1358, 1363 (Fed.Cir.2005) (“Antidumping laws intend to calculate antidumping duties on a fair and equitable basis.”). Commerce selected Jacobi and CCT as the mandatory respondents because it found that these two respondents were the largest producer/exporters of subject merchandise during the POR. In this respect, the de minimis margins must be considered more representative of industry-wide pricing behavior during the POR than the $0.28/kg calculation from the previous review, which bears no rational relationship to the POR. Commerce ordinarily gives considerable weight to the contemporaneity of data when conducting periodic administrative reviews. See Decision Mem. 13. As shown by a comparison with the Preliminary Results, the apparently controlling reason Commerce did not do so here was that the margins Commerce assigned to the mandatory respondents in the Final Results were de minimis.

Defendant argues that the margin Commerce assigned to the separate rate respondents was permissible because Commerce has “broad discretion to select any reasonable methodology.” Def.’s Resp. 21. Defendant is correct that Commerce may exercise considerable discretion in assigning a margin to the separate rate respondents in a review; however, the court disagrees that the margin Commerce chose was permissible. Where, as here, Commerce actually examined the sales of what it considered to be the two most representative respondents in the POR, and no others, that discretion does not permit the arbitrary assignment of a margin that has no rational relationship to any pricing behavior during the POR or to the likely pricing behavior of the recipients of the margin.

Defendant also points to the Department’s finding that there were no data on the record to determine whether the separate rate respondents’ pricing behavior was comparable to that of the examined respondents during the third administrative review, arguing that this finding supports the conclusion that the rates calculated during the second review are the most reliable on the record. Id. at 29 (citing Decision Mem. 6). Defendant further argues that the separate rate respondents who are plaintiffs in this case have never been assigned a de minimis margin and therefore are not entitled to one here. Id. at 29. These arguments impliedly acknowledge that the only reason Commerce changed its methodology from the Preliminary Results was the fact that both mandatory respondents received a de minimis margin. These arguments are unpersuasive because there are no record data about the pricing behavior of the separate rate respondents in the third review from which it could be reasonably inferred that the margin would, or would not, be a de minimis margin. Moreover, the state of the record is not the fault of the separate rate respondents. The available data pertaining to the POR for the third review were limited by the Department’s decision to individually examine only two mandatory respondents. See Mem. to the File (Selection of Resp’ts for Individual Review ) 6 (July 21, 2010) (Admin.R.Doc. No. 1873) (selecting Jacobi as a mandatory respondent); Mem. to the File (Selection of Additional Mandatory Resp’t) 5 (Sept. 29, 2010) (Admin.R.Doc. No. 1928) (selecting CCT as a mandatory respondent). Commerce made this decision despite its general statutory obligation to examine all respondents for which a review was requested. See 19 U.S.C. §§ 1675(a); 1677f-l(c)(2) (providing only a narrow exception where Commerce is authorized to limit the number of individually examined respondents “[i]f it is not practicable to make individual weighted average dumping margin determinations ... because of the large number of exporters or producers involved in the ... review.”). Here, there were eight respondents, including Shanxi DMD, BPAC, and GHC, who qualified for a separate rate.

The margin Commerce assigned to Huahui, like the margin assigned to the other plaintiffs, was not based on sales during the POR. However, unlike those margins, it is grounded in actual sales by Huahui, albeit sales during the previous (second) POR. The court reserves any decision on whether the margin assigned to Huahui was permissible. Commerce may or may not decide to assign Huahui a different margin based on other decisions it makes upon remand, and this Opinion and Order does not preclude Commerce from reconsidering the $0.44/kg margin assigned to Huahui in the Final Results. The court will consider this question anew upon reviewing the remand redetermination required by this Opinion and Order.

Defendant-intervenor CCC argues that the Department’s methodology is permissible because “[p]laintiffs have not demonstrated with substantial evidence that assigning them a zero average margin would be reasonable, when none of the Plaintiffs has ever had a zero margin before” and that plaintiffs have not met their burden of “establish[ing] that assigning margins from previous periods — especially for Huahui which received a margin based upon its own data from the immediately prior review — is inherently unreasonable.” CCC’s Resp. 17-18. CCC also contends that “each of the Plaintiffs affirmatively sought to participate in the third administrative review as a separate rate respondent and, therefore, had no expectation of receiving a precisely calculated, company-specific margin.” Id. at 15.

The court is not persuaded by CCC’s arguments as they apply to the $0.28/kg separate rate margin assigned to Shanxi DMD, BPAC, and GHC. The court must review the Department’s decision according to the substantial evidence standard of review; it would be unsound to attempt to shift the evidentiary burden to plaintiffs in the way that CCC suggests. The implied premise underlying CCC’s argument is that Commerce may not assign a de minimis margin to an unexamined respondent unless that respondent demonstrates with record evidence a reasonable likelihood that it would have received a de minimis margin had it actually been examined. In determining a margin for unexamined respondents, Commerce is subject to no such restriction but instead must employ a reasonable method for which it provides a rational explanation. See Bestpak, 716 F.3d at 1378.

E. Commerce Must Reconsider its Decision to Apply a Per-Unit Cash Deposit and Assessment Rate To Shanxi DMD Under the applicable regulation, Commerce “normally will calculate an assessment rate for each importer of subject merchandise covered by the review.” 19 C.F.R. § 351.212(b)(1). The regulation states, further, that Commerce “normally will calculate the assessment rate by dividing the dumping margin found on the subject merchandise examined by the entered value of such merchandise for normal customs duty purposes.” Id. Thus, the normal method as prescribed by the regulation results in an ad valorem assessment rate.

In the Final Results of the previous (second) review, Commerce deviated from the normal method by changing “the cash deposit and assessment methodology from an ad valorem to a per-unit basis,” thereby stating margins in dollars per kilogram. Certain Activated Carbon From the People’s Republic of China: Final Results and Partial Rescission of Second Anti-dumping Duty Administrative Review, 75 Fed.Reg. 70,208, 70,209 (Nov. 17, 2010) {“Final Results AR2 ”); Issues & Decision Mem., A-570-904, ARP 3-09, at 11-12 (Nov. 9, 2010) (“Decision Mem. AR2 ”). The Department made this decision upon a finding that Jacobi, a mandatory respondent and the largest Chinese exporter of subject merchandise in the second POR, was absorbing antidumping duties. Id. Specifically, Commerce had found that the domestic net unit price for Jacobi’s entries of certain activated carbon was significantly higher than the entered value reported to U.S. Customs and Border Protection (“CBP”). Final Results AR2, 75 Fed.Reg. at 70,209; Decision Mem. AR2 10-11. Commerce concluded that “while [Jacobi’s presumed duty absorption] does not prevent the Department from calculating appropriate assessment rates,” a per-unit rate is preferable because duty absorption “can result in the undercollection of duties by CBP if the Department were to issue cash deposit instructions on an ad valorem basis.” Decision Mem. AR2 11-12. Commerce further determined that this decision would be applied “to the order in its entirety” such that per-unit rates will “be applied to all respondents in this particular administrative review and all future reviews of the order.” Id. at 12.

During the third review, Shanxi DMD filed an administrative case brief challenging the Department’s continued use of a per-unit methodology. Shanxi DMD argued, inter alia, that “the per-unit rate benefits] companies who sell premium goods at higher costs while low cost goods are penalized.” Letter from Shanxi DMD to the Sec’y of Commerce 9 (June 13, 2011) (Admin.R.Doc. No. 2201) (“Shanxi DMD Case Br."). Shanxi DMD also submitted that “the Department does not actually resolve the issue at assessment because the Separate Rate Companies are not assessed antidumping duty margins based on their own data,” and that, therefore, there is “no rationale” for deviating from the normal practice of establishing the assessment rate as an ad valorem rate. Id.

In the Final Results, Commerce continued to apply per-unit assessment and cash deposit rates to all respondents, whether or not individually examined. Final Results, 76 Fed.Reg. at 67,145. As support for this decision, the Department, referencing its Decision Memorandum from the second administrative review, stated that “it would be extremely burdensome to determine whether to apply an ad valorem or a per-unit rate on a company-specific basis,” and that “[t]he change in methodology to per-unit assessment rates will not negatively impact these companies because the total duties due will not change; they will only be allocated over quantity instead of over entered value.” Decision Mem. 7 (quoting Decision Mem. AR2 12) (internal quotations omitted). In response to Shanxi DMD’s objections, Commerce stated in the Decision Memorandum that Shanxi DMD failed to provide any record evidence to rebut the presumption of continued underselling by Jacobi or to support its claim that the per-unit methodology unfairly penalizes companies that sell more low-cost subject merchandise. Id. at 8.

Shanxi DMD claims that it was unlawful for Commerce to assign it a per-unit assessment and cash deposit rate in the third administrative review, invoking the same grounds stated in its case brief. Shanxi DMD Rule 56.2 Mem. 17-25. The court agrees, concluding that the decision to assign a per-unit margin is unlawful in three respects and must be remanded to the Department.

First, Commerce impermissibly grounded its decision in a finding of duty absorption that not only pertained solely to Jacobi but also pertained to data from a previous review. Decision Mem. 7-8 (stating that Jacobi’s “behavior was the basis for the Department to use per-unit assessment rates” in the Final Results of the previous (second) administrative review). Commerce did not find that Shanxi DMD had engaged in the practice of duty absorption, and it failed to base its decision to assign Shanxi DMD a per-unit rate based on findings of fact grounded in the record of the third review. Second, Commerce attempted to justify its decision upon a finding that Shanxi DMD would not be prejudiced in any way by a per-unit rate. Id. at 7 (citations omitted) (stating that the “change in methodology to per-unit assessment rates will not negatively impact [separate rate] companies because the total duties due will not change; they will only be allocated over quantity instead of over entered value”). The court is aware of no evidence on the record of the third review to support a finding that importers of Shanxi DMD’s subject merchandise will not, under any circumstances, pay higher deposits and not be assessed higher duties than would occur under an ad valorem assessment rate.

Third, Commerce found, without an adequate evidentiary foundation, that “it would be extremely burdensome to determine whether to apply an ad valorem or a per-unit rate on a company-specific basis.” Decision Mem. 1 (citations omitted). The court fails to see why determining Shanxi DMD’s rate as an ad valorem rate would impose a significant burden. Even if some burden resulted, that burden would not justify a decision that is unsupported by findings of fact grounded in the record of the third review.

Defendant supports the Department’s determination, arguing that the plain language of the statute, 19 U.S.C. § 1673e(a)(l), and the accompanying regulation, 19 C.F.R. § 351.212(b)(1), do not require Commerce to calculate assessment and cash deposit rates in a particular manner or limit per-unit rates to particular factual circumstances. Def.’s Resp. 36-37. According to Defendant, Commerce acted within its discretion in the second administrative review when it made the global change to per-unit assessment and cash deposit rates and continued to “properly follow[ ] its practice” in doing the same in the third review. Id. at 36-37, 40 (citing Decision Mem. 7-8). Defendant also points to several Court of Appeals decisions upholding Commerce’s departure from the ad valorem methodology under certain circumstances. Id. at 36-37 (citing Koyo Seiko Co. v. United States, 258 F.3d 1340 (Fed.Cir.2001); Thai Pineapple Canning Indus. v. United States, 273 F.3d 1077 (Fed.Cir.2001)).

Defendant’s arguments are unconvincing. The cases upon which defendant relies do not establish the principle that Commerce has unfettered discretion to apply per-unit cash deposit and assessment rates. To the contrary, the Department’s discretion is not so broad as to sustain an arbitrary decision to apply a per-unit rate to Shanxi DMD, one that was not grounded in any findings pertinent to Shanxi DMD or any findings supported by evidence in the third review. Finally, defendant’s argument that Commerce properly followed its “practice” is unavailing. The “normal” method established by the regulation, 19 C.F.R. § 351.212(b)(1), is to determine ad valorem assessment rates. Here, Commerce departed from the normal practice and did so in a way that was arbitrary with respect to Shanxi DMD.

      . Activated carbon is a powdered, granular, or pelletized carbon product obtained by heat "activating” various carbon-containing materials, such as wood or coal, with steam or carbon dioxide gas. See Notice of Antidumping Duty Order: Certain Activated Carbon From the People’s Republic of China, 72 Fed. Reg. 20,988 (Apr. 27, 2007) ("Order”). The activating process removes organic materials and creates a porous inner surface in the material. See Certain Activated Carbon from China, Inv. No. 731-TA-1103, USITC Pub. 3913, at 3 (Apr. 2007) (Final) ("ITC Report"). Excluded from the scope of the antidumping duty order is "chemically-activated” carbon. Order, 72 Fed.Reg. at 20,988. Chemically-activated carbon is produced by treating the raw materials with chemicals to achieve a similar result through chemical rather than physical means. ITC Report at 3. Activated carbon is commonly used in water filtration, food and chemical purification, and emissions filtration. Id.

      If it is not practicable to make individual weighted average dumping margin determinations under paragraph (1) because of the large number of exporters or producers involved in the investigation or review, the administering authority may determine the weighted average dumping margins for a reasonable number of exporters or producers by limiting its examination to—
      (A) a sample of exporters, producers, or types of products that is statistically valid based on the information available to the administering authority at the time of selection, or
      (B) exporters and producers accounting for the largest volume of the subject merchandise from the exporting country that can be reasonably examined.

      If the Secretary has conducted a review of an antidumping order ... the Secretary normally will calculate an assessment rate for each importer of subject merchandise covered by the review. The Secretary normally will calculate the assessment rate by dividing the dumping margin found on the subject merchandise examined by the entered value of such merchandise for normal customs duty purposes. The Secretary then will instruct the Customs Service to assess antidumping duties by applying the assessment rate to the entered value of the merchandise.
      19 C.F.R. § 351.212(b)(1).
