OPINION AND ORDER
BARZILAY, Judge.

I. INTRODUCTION
The United States Department of Commerce ("Commerce" or "government") timely filed the Final Results of Redetermination Pursuant to Court Remand ("Remand Results"), pursuant to the remand order of the court in Slater Steels Corporation v. United States, 27 CIT ___, 279 F.Supp.2d 1370 (2003) ("Slater I"), the familiarity with which is presumed. The sole issue in this consolidated action (as it was in Slater I) is Commerce's "collapsing" of three companies of the Viraj Group, an Indian competitor, pursuant to 19 C.F.R. § 351.401(f) (2000) ("collapsing regulation").
The Viraj Group companies implicated in collapsing are Viraj Alloys, Ltd. ("VAL"), Viraj Impoexpo, Ltd. ("VIL"), and Viraj Forgings, Ltd. ("VFL"). "Collapsing" involves treating a group of affiliated producers as a single entity for the calculation of dumping margins.[1]
Plaintiffs and Defendants-Intervenor Slater Steels Corporation, Carpenter Technology Corporation, Electralloy Corporation, and Crucible Specialty Metals Division of Crucible Materials Corporation (collectively "domestic industry" or "Plaintiffs") submitted comments opposing the Remand Results. The Viraj Group submitted comments in support. The original determination under review is Stainless Steel Bar from India; Final Results of Antidumping Duty Administrative Review, 67 Fed.Reg. 45,956 (July 11, 2002) ("Final Results"), amended by 67 Fed.Reg. 53,336 (Aug. 15, 2002). The court has jurisdiction pursuant to 28 U.S.C. § 1581(c) (2000).

II. STANDARD OF REVIEW
The court "must sustain `any determination, finding or conclusion found' by Commerce unless it is `unsupported by substantial evidence on the record, or otherwise not in accordance with the law.'" Fujitsu General Ltd. v. United States, 88 F.3d 1034, 1038 (Fed.Cir.1996) (quoting 19 *1371 U.S.C. § 1516a(b)(1)(B)). Substantial evidence is "[m]ore than a mere scintilla;" it is "such relevant evidence as a reasonable mind might accept as adequate to support a conclusion." Consol. Edison Co. of New York v. NLRB, 305 U.S. 197, 229, 59 S.Ct. 206, 83 L.Ed. 126 (1938); Matsushita Elec. Indus. Co. v. United States, 750 F.2d 927, 933 (Fed.Cir.1984). "In applying this standard, the court affirms [the agency's] factual determinations so long as they are reasonable and supported by the record as a whole, even if there is some evidence that detracts from the agency's conclusions." Olympia Indus., Inc. v. United States, 22 CIT 387, 389, 7 F.Supp.2d 997, 1000 (1998) (citing Atlantic Sugar, Ltd. v. United States, 744 F.2d 1556, 1563 (Fed.Cir.1984)). This court may not reweigh the evidence or substitute its own judgment for that of the agency. See Granges Metallverken AB v. United States, 13 CIT 471, 474, 716 F.Supp. 17, 21 (1989). Additionally, "absent a showing to the contrary, [the agency] is presumed to have considered all of the evidence in the record." Nat'l Ass'n of Mirror Mfrs. v. United States, 12 CIT 771, 779, 696 F.Supp. 642, 648 (1988). The court's inquiry is essentially into the reasonableness of the agency's determinations.

III. DISCUSSION
In order to collapse companies for the purpose of calculating dumping margins, Commerce must first determine that the companies are "affiliated" under 19 U.S.C. § 1677(33) (2000). Commerce must next determine that the companies "have production facilities for similar or identical products that would not require substantial retooling of either facility in order to restructure manufacturing priorities," and that "there is a significant potential for the manipulation of price or production." 19 C.F.R. § 351.401(f)(1).[2] This appeal pertains only to the "substantial retooling" prong of the regulation.
In Slater I, the court found Commerce's decision to collapse the Viraj Group companies unsupported by substantial evidence and ordered Commerce "to reconsider its analysis of the collapsing issue and, if necessary, to revise its dumping margin calculations in accordance with this opinion." Slater I at 1372. In addition, the court found Commerce's articulated reasons in support of its decision "inadequate." Id. at 1378. Focusing on Commerce's evaluation of the companies' production facilities, the court questioned whether the record indicates that the production facilities of the Viraj Group companies were complementary, rather than overlapping, and whether, therefore, "substantial retooling" would be required to bring the companies' production facilities on par with one another. See id. at 1376-79.
The record indicates the following production capabilities for the Viraj Group companies. VAL has the capability to produce steel billets and black bar (hot-rolled). See Remand Results at 8. VIL has the capability to further process the black bar into bright bar (cold-finished bar). See id. at 9. VIL cannot produce black bar on its own. Further, "VFL's primary production operation relates to producing stainless steel flanges." Id. at 10. VFL "has production facilities similar to those of VIL," but unlike VAL. Id. After remand, the question remains whether "substantial retooling" of their production facilities would not be required for these companies to divert production of subject *1372 merchandise from one another to take advantage of dumping margin differentials.
This case highlights the degree of confusion pertaining to the interpretation of the collapsing regulation, and the incongruity manifested in applying the regulation to the facts at hand. After due deliberation, the court finds that the Remand Results fall short of satisfying its order in Slater I because the Remand Results do not follow the collapsing regulation, and because Commerce did not provide the court with adequate factual support and justification in support of its decision to collapse the Viraj Group companies. The court once again remands the case to Commerce to reevaluate its collapsing decision, and specifically address and answer the questions that are raised in this opinion under separate subheadings.

A. Commerce must explain why it did not analyze the "substantial retooling" prong of the collapsing regulation separately from the "manipulation" prong in this case.
As urged by the domestic industry, see Pls.' Comments at 11-12, section 351.401(f)(1) has two distinct and separate parts, the "substantial retooling" and "manipulation" prongs, which are joined by the word "and." Because the regulation is conjunctive, each element has to be met. While the Remand Results contain sufficient evidence in support of the government's affirmative determination on the "manipulation" issue, the Remand Results do not provide sufficient evidence and analysis of "substantial retooling." The evidence Commerce cites in support of its decision to collapse all bear on the question of "manipulation." That evidence, however, is irrelevant in the analysis of "substantial retooling." The issue in this appeal (as it was in Slater I) is "substantial retooling." The Remand Results do not sufficiently address (and in fact distract from) the examination of the companies' production facilities, which is the proper analysis of the "substantial retooling" question.
The government attempts to bring into its "substantial retooling" analysis the "manipulation" prong of the collapsing regulation by emphasizing that "the policy rationale of the collapsing regulation is to prevent affiliated companies with the same or similar production capabilities from manipulating price or production activities of subject merchandise to the affiliated company with the lowest margin, and thereby circumventing the antidumping law." Remand Results at 5 (citing and paraphrasing Slater I at 1376 in a misleading manner)[3] (emphasis added). The government justifies its approach by arguing that "the central question of the collapsing regulation" is the price or production "manipulation" issue. Remand Results at 6 (citing Queen's Flowers de Colombia v. United States, 21 CIT 968, 979, 981 F.Supp. 617, 628 (1997)) & at 11 (citing Antidumping Duties; Countervailing Duties, 62 Fed.Reg. 27, 296, 27,346 (May 19, 1997) ("Preamble")).
In making the "manipulation" issue the "central question" in this appeal, Commerce lists a number of factors that need to be examined with respect to the "manipulation" issue pursuant to 19 C.F.R. § 351.401(f)(2). For example, Commerce points out that the Viraj Group companies *1373 "are sufficiently intertwined and have similar production capabilities." Id. at 6. Commerce reiterates that "the Viraj Group is a large, integrated, multinational entity in which two individuals hold the majority of shares, either directly or, along with friends and relatives and their promoted companies." Id. at 11 (quoting Viraj Group's June 29 and November 26, 2001 questionnaire responses) (internal quotation marks omitted). Further, "[t]hese same two individuals are also the managing directors of all three affiliates;" "[t]he selling and production activities for bar during the period of review at VIL and VAL are controlled by these directors;" "[t]hrough personal guarantees, these same two individuals also enabled VIL and VFL to secure loans that they may not otherwise have received;" "[i]n fact, VIL received a loan for working capital which was not only guaranteed by the directors but also by VAL;" "[i]n addition, the directors made direct loans to VAL and VFL;" "VAL, VIL, and VFL's production facilities are all located in the same city" and "positioned hardly 20 meters away from each other." Id. at 12 (quotation marks omitted). To the extent all this information relates to 19 C.F.R. § 351.401(f)(2), which contain the "manipulation" factors to be examined, the court finds the information unhelpful for the purposes of reviewing Commerce's decision that "substantial retooling" would not be necessary.
Moreover, Commerce's recent practice in collapsing is "to refrain from collapsing firms when there are differences in production facilities that would require substantial retooling." Certain Porcelain-on-Steel Cookware From Mexico: Final Results of Antidumping Duty Administrative Review, 62 Fed.Reg. 42,496, 42,497 (Aug. 7, 1997) ("Porcelain-on-Steel"). Commerce does not reach the "manipulation" issue when the "substantial retooling" prong of the regulation is not met. See Certain Welded Carbon Steel Pipes and Tubes from Thailand: Preliminary Results of Antidumping Duty Administrative Review, 63 Fed.Reg. 16, 974, 16,976 (April 7, 1998) ("Steel Pipes") ("Because we determine that the second[, `substantial retooling,'] criterion is not satisfied, it is not necessary to consider the third criterion in the collapsing analysis  identifying the potential for manipulation of price or production."). Commerce specifically rejected a "totality of circumstances" approach in favor of its current practice. See Porcelain-on-Steel at 42,497. Under the "totality of circumstances" approach, examining production facilities was a factor considered in collapsing, and no one factor was dispositive. See Final Determinations of Sales at Less Than Fair Value: Certain Hot-Rolled Carbon Steel Flat Products, Certain Cold-Rolled Carbon Steel Flat Products, and Certain Corrosion-Resistant Carbon Steel Flat Products from Japan, 58 Fed.Reg. 37,154, 37,159 (July 9, 1993) (considering factors, such as "degree of voting control," "financial relationship," "intertwined" operations, companies'"transactions with each other," and capability "of manipulating prices or affecting production decisions, through their sales and production efforts," as well as production facilities). The current form of section 351.401(f) that solidified Commerce's new collapsing practice was adopted in 1997 and is explained in the Preamble, which seeks to clarify the "degree of confusion concerning [Commerce's] practice of collapsing." Preamble at 27,345. That confusion seems to have survived into Commerce's handling of the Viraj companies' case.
The Preamble is clear in its insistence on a separate analysis of "substantial retooling":
In addition to finding a significant potential for manipulation, [Commerce] also must find the requisite type of production facilities. To clarify this point, *1374 we have revised paragraph (f) so that paragraph (f)(1) refers to the two basic elements, while paragraph (f)(2) contains the non-exhaustive list of factors that [Commerce] will consider in determining whether there is a significant potential for manipulation.
Preamble at 27,346 (emphasis added). Furthermore, to the extent that Queen's Flowers, which the government cites in support of its assertion, examined an agency determination that had predated the new regulation, the view of the Queen's Flowers Court on collapsing is not directly on point here. The regulation and, accordingly, the agency's practice on collapsing have changed since the Queen's Flowers decision.[4]
It is imperative that an agency follow its own regulations. See Slater I at 1378 (citation omitted). Commerce asserts that it has "discretion" to collapse the Viraj Group companies. Remand Results at 5 (citation omitted). However, the agency does not have discretion to violate a rule it adopted after notice and comment, fulfilling a legislative function. See United States v. Nixon, 418 U.S. 683, 694-96, 94 S.Ct. 3090, 41 L.Ed.2d 1039 (1974). The government reiterates that "the collapsing analysis must be made with a keen understanding of all of the facts of the case, taken as a whole, rather than any individual piece of the analysis being the ultimate determinative factor." Remand Results at 20 (citing its Draft Remand at 13). While this may be true, the new collapsing regulation on its face (and as explained in the Preamble) demands a separate analysis and a separate finding on the issue of "substantial retooling."
In tandem, while the agency "may depart from its earlier determinations and its own prior precedent, whatever the ground for departure from prior norms, however, it must be clearly set forth so that the reviewing court may understand the basis of the agency's actions and so may judge the consistency of that action with the agency's mandate." Marine Harvest (Chile) S.A. v. United States, 26 CIT ___, 244 F.Supp.2d 1364, 1380 (2002) (citations and internal quotation marks omitted). In its Remand Results Commerce should have clearly articulated to the court its reasons for the deviation from its current practice of analyzing the "substantial retooling" prong separately, see, e.g., Steel Pipe at 16,976, and why it chose to engage in a type of "totality of circumstances" approach in this case, which it has otherwise abandoned.
In subsequent remand, Commerce must focus on the companies' production facilities and on whether or not "substantial retooling" of facilities would be required "in order to restructure manufacturing priorities." 19 C.F.R. § 351.401(f)(1). And it must do so without reference to the factors that bear on the "manipulation" issue in support. This is what is required under the regulation, Commerce's own practice, and the Preamble.[5]


*1375 B. In applying its collapsing regulation, Commerce must explain why it need not analyze the production facilities of each company and why in this case its analysis centered on the products the companies manufacture.

1. Commerce must explain why it need not examine the production facilities of each company involved in collapsing and why it need not address the possibility of shifting production among companies in either direction.
Another question that relates to the proper interpretation of the "substantial retooling" prong of the collapsing regulation is whether Commerce must examine the production facilities of each company involved or whether it is sufficient for Commerce to examine the production facilities of only one company. The regulation reads "production facilities for similar or identical products that would not require substantial retooling of either facility in order to restructure manufacturing priorities." § 351.401(f)(1) (emphasis added). Plaintiffs interpret the regulation to mean that each company's production facilities need to be examined. See Pls.' Comments at 10 ("VAL, VIL, and VFL each lack similar production capabilities."). The court finds Plaintiffs' argument on this point persuasive.
The regulation appears to require that Commerce examine the production facilities of both (or all) companies and evaluate the possibility that production may be shifted from one company to another and vice versa. The first dictionary meaning of the word "either" is "each of the two." 5 OXFORD ENGLISH DICTIONARY 102 (2d ed.1989). Moreover, when used with a plural noun, the proper word to replace "either" is "both." Id. These definitions seem to support Plaintiffs' position. On the other hand, a secondary definition of the word "either" is "one or other of the two." Id. This definition seems to support the government's position. This court will give substantial deference to the agency's reasonable interpretation of its own regulation unless it is plainly erroneous and inconsistent with the regulation. See Mullins Coal Co. v. Director, 484 U.S. 135, 159, 108 S.Ct. 427, 98 L.Ed.2d 450 (1987) (citation and internal quotation marks omitted). However, given two competing interpretations of the regulation and the record evidence in this case of very sparse of overlap of production facilities combined with the concern that collapsing the Viraj Group may lead to circumventing the United States antidumping duty law, the court requires more explanation from Commerce *1376 why its interpretation of the regulation is reasonable in this case. Specifically, Commerce must look further into the possibility that the Viraj Group affiliates may not be able to shift production from VAL to VIL (or VFL) without "substantial retooling."
Here, Commerce focused solely on the production facilities of VAL in finding that "VAL could add bright bar finishing operations [which VIL already has] for less than 10 percent of its current fixed asset value" and in finding that this percentage does not constitute "substantial retooling." Remand Results at 9. With respect to VIL, Commerce simply observed that "VIL has the ability to purchase black bar on the open market, rather than from VAL, and process it into bright bar using the production facilities it already has."[6]Id. Accordingly, Commerce concluded that "VAL and VIL have production facilities to make similar or identical products without substantial retooling of VAL's production facility in order to restructure manufacturing priorities." Id.
While not sufficiently addressing whether VIL's facilities would need "substantial retooling," Commerce's determination does not address the possibility that VIL might receive a lower margin than VAL.[7]See Pls.' Comments at 20. As it stands now, the record shows that VIL does not have the production facilities required to produce the black bar or billet VAL produces and that a substantial addition to VIL's facilities may be needed for VIL to produce black bar or billet.[8] In the event that VIL receives a lower dumping margin than VAL, the Viraj Group may not be able to divert the production of black bar to VIL without "substantial retooling" of VIL's facilities. VIL on its own cannot produce black bar or billet. To produce bright bar, VIL must purchase the input or the intermediate product, black bar, either from VAL or from a third party. In the event VIL purchases black bar or billet from VAL, that purchase may have to be examined with scrutiny because of the affiliated nature of the companies. Such examination would not be possible if the companies were collapsed. See Slater I at 1377 (questioning whether the use of the "major input rule" under 19 U.S.C. § 1677b(f)(3) and 19 C.F.R. § 351.407(b), rather than collapsing, may be more appropriate in this case).[9]
*1377 While lacking the analysis of VIL's production facilities, the Remand Results are also perfunctory with respect to VFL's production facilities. As recognized by Commerce, "VFL's primary production operation relates to producing stainless steel flanges, and therefore, some of its production machinery is used exclusively for producing flanges," and not bar. Remand Results at 10. While, as admitted by Commerce itself, see id., the focus should be on the company's production facilities, rather than the question of whether or not VFL produces subject merchandise, the court's concerns relating to the insufficient analysis of VIL's capabilities are equally implicated with respect to VFL's capabilities. As Commerce says, "VFL ... has production facilities similar to those of VIL." Id. In particular, "VFL also has heating and annealing capabilities" without the capability to make black bar. Id. Notwithstanding the new information that VFL installed facilities for and produced and sold "forged rounds/bars /rods," id. (internal quotation marks omitted), Commerce does not point to any evidence in the record that VFL has the capability to produce black or bright bar.[10]

2. Commerce must explain why in this case it focused on the products the companies' manufacture, rather than their production facilities.
Intertwined with the question as to whether each company's production facilities need to be evaluated is the related issue of whether the collapsing regulation refers to production facilities or product lines. Commerce states that the court "has specifically allowed for differences between production lines and products." Id. at 11 (citing Marine Harvest, 244 F.Supp.2d at 1367-68 n. 8).[11] In fact, Commerce centers a significant portion of its discussion in the Remand Results on the fact that black bar and bright bar are both subject merchandise defined by the scope of the administrative review, see Final Results at 45,957, and concludes that, therefore, VAL and VIL have production facilities that would not require "substantial retooling." See Remand Results at 6-7.
As Plaintiffs rightly observe, see Pls.' Comments at 5-6, Commerce's interpretation of section 351.401(f)(1) in this manner would render a part of the "substantial retooling" prong hollow. Again, the regulation reads "production facilities for similar or identical products that would not require substantial retooling ... in order to restructure manufacturing priorities." § 351.401(f)(1). It is insufficient for Commerce to declare that, because black and bright bar are similar products under the definition of subject merchandise, their production facilities do not require "substantial retooling."[12] In order to be able to collapse the Viraj Group, Commerce must specifically address the question that the companies' production facilities for *1378 similar products would not require "substantial retooling." Cf. Issues and Decision Mem. accompanying German Bar cmt. 15 ("section 351.401(f)(1) concentrates not on a firm's product line, but rather on its production facilities.").
Despite the fact they may both be subject merchandise, the record indicates that the production facilities needed for the production of black bar and bright bar may not be similar. The record shows that the black bar produced by VAL is an input in the production of bright bar (produced by VIL). VIL's function in the production of bright bar is "finishing" the product at the last stage of production. "VIL picks up where VAL leaves off." Pls.' Comments at 9. Further, VAL supplies VFL with billet which VFL on its own cannot produce. So far Commerce has not demonstrated that VAL, VIL, and VFL can shift production of black or bright bar (or, for that matter, any other product) from one another without "substantial retooling" of their facilities, thereby avoiding high dumping margins and circumventing the United States antidumping law. See Slater I at 1376.[13]

C. Commerce must explain why an investment even if worth less than 10 percent of a company's fixed asset value does not constitute "substantial retooling" and why this figure by itself is sufficient to make Commerce's "substantial retooling" determination reasonable.
Commerce determined that "VAL could add bright bar finishing operations (e.g., pickling and annealing operations) for less than 10 percent of its current fixed asset value" to be able to produce the bright bar.[14]Remand Results at 9. Commerce *1379 further determined that this potential investment does not constitute "substantial retooling." However, it is hardly possible to evaluate whether this number is significant when it is not presented in context and in relation to a reference point. At first glance, an investment that costs less than 10 percent of fixed value of a company's assets, to the extent that cost approaches 10 percent, seems to be a significant outlay. Commerce must explain to the court why it determines that an investment that may approach 10 percent of VAL's fixed asset value is not "substantial." Moreover, Commerce must tell the court whether any other consideration, beside the monetary value of the investment, may implicate the "substantial retooling" question, such as time that may have to be spent or other constraints on the company's finances.[15]
It is well-known that a decision to collapse is "very much fact-specific in nature, requiring case-by-case analysis." Preamble at 27,346. However, presenting a raw number without more does not give the court the opportunity to review Commerce's decision in a meaningful way. This court may not accept Commerce's assertions on faith, but is required to evaluate whether they are reasonable inferences based on facts. See Atlantic Sugar, Ltd. v. United States, 744 F.2d 1556, 1562 (Fed.Cir.1984) ("substantial evidence on the record means more than a mere scintilla and such relevant evidence as a reasonable mind might accept as adequate to support a conclusion, taking into account the entire record, including whatever fairly detracts from the substantiality of the evidence") (citation and internal quotation marks omitted).
To illustrate how the citation of one value out of context does not lend itself to a meaningful review, it is instructive to look at Plaintiffs' counter-argument. Plaintiffs would like the court to hold that "substantial retooling" would be required of VAL's facility to produce bright bar. See Pls.' Comments at 21. To advance this position, Plaintiffs argue that Commerce must not ignore "the magnitude of the absolute value of the expense of retooling for VAL," in favor of the percentage value cited by Commerce. Id. at 22. To that end, Plaintiffs give the court yet another number: retooling VAL's facility would "equal to over half a million dollars in assets." Id. More persuasively, Plaintiffs add that "VFL would have to increase its investments in plant and machinery assets by almost Rs. [(Rupees)] 175 million in order to create a production facility similar to that of VAL." Id. at 19. And "[t]his is prohibitive for a company that only posted a net profit in [Fiscal Year] 2000 of less than Rs. 14 million  and would qualify by any measure as a `substantial retooling' investment." Id.
The question is whether any numbers cited would reasonably support the conclusion that the required investment would *1380 not be "substantial." Therefore, Commerce needs to justify its position more fully and more responsively. Instead, Commerce merely replies to Plaintiffs' comments that "[o]bviously, Commerce looks at the relative proportion of the fixed assets when conducting such an analysis because the absolute values are meaningless when considering whether adding such facilities would be substantial for a particular company." Def.'s Response at 11-12. This is an inadequate explanation. Commerce must explain to this court why the number it cites as the value of new potential investment (either in percentages or in absolute terms) in the Remand Results would not reasonably constitute "substantial retooling" within the meaning of the regulation.

D. Commerce must explain why it finds unnecessary to address the relative merits of collapsing and the major input rule as they relate to the facts of this case.
In Slater I, the court suggested that the application of the "major input rule" pursuant to 19 C.F.R. § 351.407(b)[16] may have been more appropriate in this case, as opposed to collapsing the companies. See Slater I at 1377. Plaintiffs have repeatedly raised the same issue in their comments to the agency and the court. Instead of addressing the issue, the government merely observes that "[b]ecause [the major input] provision only applies to transactions between affiliated persons, once [Commerce] decided to collapse and treat the companies as one `person' for the purposes of the antidumping analysis, it is not statutorily required to apply the provision." Remand Results at 15 (citation omitted). The government continues, "[i]n this case, [Commerce] determined that the Viraj Group companies is one entity and, therefore, the major input rule does not apply in this situation."[17]Id.
There is no question that, when Commerce determines to collapse the companies, the major input rule does not apply because the rule relates to the examination of transactions between affiliates and, once the affiliates are treated as one entity, there is no reason or opportunity to examine such transactions. However, the position that the major input rule does not apply here because Commerce had already determined to collapse the Viraj Group companies is a non sequitur. Given the court's concerns in Slater I regarding affiliate transactions among the Viraj Group companies, the government needs to examine the relative merits of collapsing vis a vis the major input rule as applied or applicable to the facts of this case. See Slater I at 1377. That is to say that Commerce must directly refer to the Viraj Group companies' production relationships which the record shows to be more like a supplier and a buyer, and complementary. *1381 Two of the companies (VIL and VFL) reportedly buy a major input used in their production facilities from an affiliate (VAL).[18] If the production facilities of the companies are indeed complementary, collapsing the Viraj Group may lead to potential misstatements in the disclosure of the companies' cost structures and manipulation of dumping margin calculations that should (and could) not be permitted under the statute.

IV. CONCLUSION AND ORDER
For all the foregoing reasons, the court finds that the Remand Results fall short of satisfying the court's instructions in Slater I. Commerce must address and answer the points that are raised under separate subheadings in this opinion. Therefore, it is hereby
ORDERED that the case is remanded to Commerce to reevaluate its collapsing decision; it is further
ORDERED that Commerce shall have sixty (60) days, until May 7, 2004, to complete and file its review. Plaintiffs and Defendants-Intervenor shall have thirty (30) days from that filing to file comment(s), and any reply by Commerce shall be due twenty (20) days after Plaintiffs' comment(s) are filed.
NOTES
[1]  This case does not involve partial collapsing.
[2]  For ease of exposition, the court will refer to the first part of the collapsing regulation as the "substantial retooling" prong; and the second part, as the "manipulation" prong. The court notes that there is no statutory provision governing collapsing.
[3]  Despite the government's attempt to paraphrase the court's language to include the "manipulation" issue, the exact quote from Slater I is: "The policy rationale behind collapsing is to prevent affiliated exporters with same or similar production capabilities to channel production of subject merchandise through the affiliate with the lowest potential dumping margin and thereby circumvent the United States antidumping law." Slater I at 1376 (emphasis added). Slater I did not reach the "manipulation" issue. Id. at 1375 n. 8.
[4]  Defendant's credibility is not enhanced by its failure to bring this fact to the court's attention.
[5]  The Remand Results' confusion relating to the application of the separate prongs is further exposed by Commerce's discussion of the German Bar case. See Remand Results at 13-14 (discussing Notice of Final Determination of Sales at Less Than Fair Value: Stainless Steel Bar From Germany, 67 Fed.Reg. 3159 (Jan. 23, 2002) ("German Bar")). Plaintiffs argue that the German Bar case does not support Commerce's decision to collapse the Viraj Group. In German Bar, Commerce determined that, even though the German Bar companies had production facilities that could produce similar and identical merchandise in a limited range of bar diameters, they "would need to add entire production lines, not merely retool the existing operations" in order "to meaningfully expand the range of sizes produced at either plant." Issues and Decision Mem. accompanying German Bar cmt. 15. In other words, the production lines had "limited" overlap. Id. In the Remand Results, Commerce answers Plaintiffs' argument by observing that the German Bar companies were not "collapsed because of the combination of a `limited overlap' in production capabilities and significant corporate structural impediments of the [companies'] ability to manipulate pricing and production." Remand Results at 13 (emphasis in the original). In German Bar, however, Commerce engaged in an analysis of the "manipulation" issue, only because it found some overlap in the facilities, while cautioning that it was "[k]eeping in mind that the potential for manipulation is constrained by this limited overlap." The record here is equivocal about whether the Viraj Group companies' facilities have any overlap (let alone the "broad overlap" asserted by Commerce). The German Bar notice was very specific that the factors outlined in section 351.401(f)(2) implicated the "manipulation" issue, not the "substantial retooling" issue  an approach not taken, but should have been taken, by the Remand Results. Further, on the "manipulation" issue, the German Bar companies were owned by the same entity and had two common board members, whereas the Viraj Group does not have a common parent, but has common managing directors. See Viraj Group's Reply to Pls.' Comments at 4-5.
[6]  The court recognizes that VIL has the ability to purchase black bar on the open market. The record indicates that in the period of review either VAL supplied VIL with black bar or VIL leased VAL's facilities. The Remand Results do not sufficiently address the concern that any transaction between VAL and VIL (or VFL) may not be at arm's-length.
[7]  Commerce only gives the example of VAL receiving a lower margin.
[8]  VIL may have to add, for instance, induction and refining furnaces and argon oxygen decarburiser converters to produce black bar. See Slater I at 1376-77. Whether or not this constitutes "substantial retooling" is a question Commerce must decide.
[9]  Furthermore, there is still the question of whether or not there was a leasing arrangement between VIL and VAL during the period of review, which would have allowed VIL to use VAL's facilities for the production of hot-rolled round bar and billet. Commerce now announces that "the leasing agreements were not a determinant factor in [Commerce's] collapsing determination in this case." Remand Results at 16; see also Def.'s Response at 15 ("The alleged leasing agreement [is] not part of Commerce collapsing analysis."). Contrary to the government's surprising assertion here, in the Final Results Commerce specifically based its determination to collapse on its finding that "VAL and VIL can produce subject merchandise (i.e., similar or identical products) and can continue to do so, independently or under existing leasing agreements, without substantial retooling of their production facilities." Issues and Decision Mem. accompanying Final Results cmt. 1. Again because a leasing arrangement, if any, would constitute a transaction between affiliated entities, it may have to be examined with special scrutiny  which examination Commerce's decision to collapse the Viraj Group companies does not allow.
[10]  Plaintiffs state: "VFL does not make any bar products but may have annealing capabilities to make one intermediate product, HRAP [(hot-rolled, annealed, pickled)] bar; its heavy forge equipment may be able to make large forged bar unlike either VAL's black bar or VIL's bright bar." Pls.' Comments at 26. That is, in the event Commerce finds after reconsideration that VIL and VAL should be collapsed, it has to further explain how production facilities used to make forged bar and production facilities used to make black or bright bar are overlapping.
[11]  The issue implicated in Marine Harvest was the successor-in-interest test, not a decision to collapse. Moreover, the Marine Harvest companies' production relationships were different than the Viraj Group companies: they did not produce the intermediate and the finished product respectively, as do the Viraj Group companies.
[12]  The subject merchandise is defined in the Final Results as follows:

Imports covered by this review are shipments of stainless steel bar ("SSB"). SSB means articles of stainless steel in straight lengths that have been either hot-rolled, forged, turned, cold-drawn, cold-rolled or otherwise cold-finished, or ground, having a uniform solid cross section along their whole length in the shape of circles, segments of circles, ovals, rectangles (including squares), triangles, hexagons, octagons, or other convex polygons. SSB includes cold-finished SSBs that are turned or ground in straight lengths, whether produced from hot-rolled bar or from straightened and cut rod or wire, and reinforcing bars that have indentations, ribs, grooves, or other deformations produced during the rolling process. Except as specified above, the term does not include stainless steel semi-finished products, cut length flat-rolled products (i.e., cut length rolled products which, if less than 4.75 mm in thickness, have a width measuring at least 10 times the thickness, or, if 4.75 mm or more in thickness, have a width which exceeds 150 mm and measures at least twice the thickness), wire (i.e., cold-formed products in coils, of any uniform solid cross section along their whole length, which do not conform to the definition of flat-rolled products), and angles, shapes and sections.
[13]  In Slater I, the court also ordered Commerce to explain its turnabout relating to the nature of the companies production facilities. See Slater I at 1379. In particular, in its preliminary results Commerce determined that the Viraj Group companies' production facilities are "complementary," while in the Final Results it determined that they are "overlapping." The corollary to the "substantial retooling" question is whether the companies' production facilities have a "broad overlap." In the Remand Results Commerce answered the court's concerns by maintaining that "both descriptions are true." Remand Results at 12. As explained above, Commerce based this assertion on the detail that black and bright bar are both subject merchandise. This assertion does not, however, resolve the question whether the production facilities of the black and bright bar are "overlapping" to a sufficient degree. So far, it appears that their production facilities are complementary, with little or no overlap.
[14]  Commerce must also explain to the court whether VAL, by merely adding annealing and pickling operations, could produce the cold-rolled bright bar that VIL produces. See Pl.'s Comments at 18 (asserting that the addition of annealing and pickling equipment would merely enable VAL to make hot-rolled, annealed, pickled bar [HRAP] and that to produced cold-finished bar, VAL has to also add cold-turning, -polishing, -rolling, -grinding, and -drawing equipment). The government answers that the 10 percent figure encompasses these finishing equipment, and only points to the Viraj Group's June 29 questionnaire response at 90 and 73. See Def.'s Response at 11.
[15]  The need to provide sufficient context and a reference point can be illustrated with the following examples. (These examples are for illustration only.) To wit, expending close to 10 percent of fixed asset value may be a relatively insignificant investment for a large and diversified company, while such an investment may not be feasible for a smaller company. Or a less than 10 percent investment may be insubstantial under industry norms. Moreover, if an investment would take longer to implement than the period the companies are under review, that investment may constitute "substantial retooling."
[16]  Section 351.407 (Calculation of constructed value and cost of production) reads:

(a) Introduction. This section sets forth certain rules that are common to the calculation of constructed value and the cost of production. (See section 773(f) of the Act.)
(b) Determination of value under the major input rule. For purposes of section 773(f)(3) of the Act[, 19 U.S.C. § 1677b(f)(3)], the Secretary normally will determine the value of a major input purchased from an affiliated person based on the higher of:
(1) The price paid by the exporter or producer to the affiliated person for the major input;
(2) The amount usually reflected in sales of the major input in the market under consideration; or
(3) The cost to the affiliated person of producing the major input.
[17]  Elsewhere (in reply to Plaintiffs' comments), the government also states that "[b]ecause we have determined to continue to collapse the Viraj Group companies, we did not address the plaintiffs' suggestions with respect to `the major input rule' in the remand redetermination." Remand Results at 16.
[18]  Or (if this matter were ever to be resolved) VIL uses VAL's facilities under an exclusive leasing arrangement. In addition to asserting that Commerce's decision was not based on the existence of a leasing arrangement in the period of review, see note 9, the Remand Results also observe that Commerce first heard of the existence of a leasing agreement when it received the Viraj Group's Rebuttal Brief. See Remand Results at 15. With these remarks Commerce implies that it is now not basing its decision to collapse on the leasing agreements, even though it seemed to do so in the Final Results. Not only does this court find the less than ideal clarity of the record in this case disheartening, but also agrees with Plaintiffs that the record at a number of places contains an indication of this leasing arrangement. The court here will not pass judgment on Plaintiffs' assertion, which incidentally elicited no response from the government, that "the very fact of an affiliate [(VIL)] resorting to operational leasing of another affiliate's [(VAL's)] production/equipment facility is per se evidence that it does not, on its own, have that production capability." Pls.' Comments at 14. Commerce, however, must address the issue of these leasing arrangements and explain to the court why it changed its position regarding such arrangements in its decision to collapse the Viraj Group companies and in its continuing defense of that decision.
