Court No. 24-00070 Page 2
Gordon, Judge: This action involves the U.S. Department of Commerce’s
(“Commerce”) final results in the administrative review of utility scale wind towers from
the Republic of Korea. See Utility Scale Wind Towers from the Republic of Korea, 89 Fed.
Reg. 16,544 (Dep’t of Commerce Mar. 7, 2024), as corrected in Utility Scale Wind Towers
from the Republic of Korea: Final Results of Antidumping Duty Administrative Review;
2021-2022; Correction, 89 Fed. Reg. 22,372 (Dep’t of Commerce Apr. 1, 2024), and
accompanying Issues and Decision Memorandum.
Before the court is Commerce’s Final Results of Redetermination Pursuant
to Court Remand, ECF No. 52-1 (“Remand Results”), filed pursuant to Wind Tower Trade
Coal. v. United States, 49 CIT ___, 810 F. Supp. 3d 1351 (2025) (“Wind Tower I”).
Plaintiff Wind Tower Trade Coalition challenges Commerce’s decision not to adjust
Defendant-Intervenor Dongkuk S&C Co., Ltd.’s (“Dongkuk” or “DKSC”) direct variable
overhead costs (“direct VOH” or “direct conversion costs”), while Defendant-Intervenor
challenges Commerce’s determination to adjust Dongkuk’s indirect conversion costs.

Court No. 24-00070 Page 3
and 28 U.S.C. § 1581(c). The court presumes familiarity with prior proceedings in this
action. For the reasons set forth below, the court sustains Commerce’s Remand Results.
I. Standard of Review
The court sustains Commerce’s “determinations, findings, or conclusions” 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). More specifically, when reviewing
agency determinations, findings, or conclusions for substantial evidence, the court
assesses whether the agency action is reasonable given the record as a whole.
Nippon Steel Corp. v. United States, 458 F.3d 1345, 1350–51 (Fed. Cir. 2006);
see also Universal Camera Corp. v. NLRB, 340 U.S. 474, 488 (1951) (“The substantiality
of evidence must take into account whatever in the record fairly detracts from its weight.”).
Substantial evidence has been described as “such relevant evidence as a reasonable
mind might accept as adequate to support a conclusion.” DuPont Teijin Films USA v.
United States, 407 F.3d 1211, 1215 (Fed. Cir. 2005) (quoting Consol. Edison Co. v.
NLRB, 305 U.S. 197, 229 (1938)). Substantial evidence has also been described
as “something less than the weight of the evidence, and the possibility of drawing
two inconsistent conclusions from the evidence does not prevent an administrative
agency’s finding from being supported by substantial evidence.” Consolo v. Fed. Mar.
Comm’n, 383 U.S. 607, 620 (1966).
Fundamentally, though, “substantial evidence” is best understood as a word
formula connoting reasonableness review. 3 Charles H. Koch, Jr. & Richard Murphy,
Administrative L. and Prac. § 9.24[1] (3d ed. 2026). Therefore, when addressing
Court No. 24-00070 Page 4
a substantial evidence issue raised by a party, the court analyzes whether the challenged
agency action “was reasonable given the circumstances presented by the whole record.”
8A West’s Fed. Forms, Nat’l Courts § 3.6 (5th ed. 2026).
II. Background
The court remanded this matter to Commerce for further explanation, and
if appropriate, reconsideration of its cost analysis under 19 U.S.C. § 1677b(f)(1)(A)
because: (1) “Commerce failed to explain why Dongkuk’s reported conversion costs were
appropriate”; (2) “Commerce did not address the first three enumerated CONNUM
characteristics”; and (3) “Defendant’s explanation as to the significance in differences
between direct and indirect variable conversion costs is not reflected within Commerce’s
[decision].” Wind Tower I, 810 F. Supp. 3d at 1358–59. On remand, “after reviewing
the record evidence, [Commerce] reconsidered [its] treatment of Dongkuk’s indirect
conversion costs.” Remand Results at 3. As a result of this reconsideration,
it recalculated and adjusted Dongkuk’s weight-average dumping margin to 1.90 percent.
Id. at 19.
III. Discussion
A. Commerce’s Reconsideration of Dongkuk’s Indirect Conversion Costs
Under 19 U.S.C. § 1677b(f)(1)(A), Commerce relies on a respondent’s records:
(1) “if such records are kept in accordance with the generally accepted accounting
principles of the exporting country” and (2) “reasonably reflect the costs associated with
the production and sale of the merchandise.” On remand, Commerce first looked
at Dongkuk’s reported indirect conversion costs. In so doing, Commerce explained
Court No. 24-00070 Page 5
that Dongkuk “allocated its indirect conversion costs, which are generally ‘fixed’,
by production quantity (in metric tons (MT)) in its normal books and records” and that
“‘in the normal course of accounting, the same unit price per ton is applied to all projects
regardless of the circumstances.’” Remand Results at 3. However, in its review,
Commerce found that despite Dongkuk’s assertion that “the same unit price per ton
is applied to all projects,” Dongkuk’s reported indirect conversion costs actually “vary
greatly in spite of its claim that the ‘same unit price per ton’ is applied to all projects.” Id.
Commerce similarly found that “[t]he differences in the reported indirect conversion costs
also appear to be unrelated to the product characteristics, as there is no discernable
increase in these costs when the reported CONNUMs increase in complexity.” Id.
Consequently, Commerce found that while “Dongkuk reported its costs based on its
normal books and records, in which Dongkuk allocates indirect conversion costs on
a monthly basis,” its indirect conversion costs methodology “is distortive and not reflective
of the actual cost of producing the merchandise,” and “appropriate to deviate from.” Id.
(emphasis added).
Because it found that Dongkuk’s indirect conversion costs methodology is not
reflective of producing the wind towers, Commerce decided to utilize its normal practice
of relying on annual average costs during the period of review (“POR”) to calculate
a respondent’s cost of production. Id. According to Commerce, POR annual average
costs “‘minimize fluctuations in the production cost experienced by the respondent over
short periods of time, where these fluctuations do not reflect differences in the physical
characteristics of the products’” and “‘reduce the effect of fluctuating raw material costs,
Court No. 24-00070 Page 6
erratic production levels, major repairs and maintenance, inefficient production runs, and
seasonality.’” Id. at 4–5 (quoting Stainless Steel Bar from the United Kingdom, 72 Fed.
Reg. 43,598 (Dep’t of Commerce Aug. 6, 2007) (“Stainless Steel Bar from the UK”), and
accompanying Issues and Decision Memorandum). Commerce’s POR average
calculation was then applied to “the reported CONNUM-specific indirect conversion costs
on a per-piece basis . . . to calculate the revised indirect conversion costs on a per-piece
basis.” Id. at 6. Ultimately, Commerce found that this revised indirect conversion cost
methodology “more closely reflect[ed] the increasing complexity of th[e] product
characteristics” laid out by the court: weight, height, and tower sections, “such that there
are no longer unexplained variations.” Id. at 7.
In its opposition comments, Dongkuk argued that, as previously explained to the
agency and the court, its “conversion costs reasonably reflected costs associated with the
production of wind towers.” Def.-Intervenor’s Opp’n Comments at 4. Therefore,
in response to the court in Wind Tower I, Dongkuk maintains that Commerce “should
provide further explanation that no smoothing adjustment to DKSC’s reported indirect
conversion costs was warranted” and that its “cost reporting methodology was
reasonable[, as] substantial record evidence demonstrated.” Id.
Despite Dongkuk’s position, Commerce continued to recalculate Dongkuk’s
indirect conversion costs in accordance with its draft remand redetermination, finding that
“Dongkuk essentially reiterates its explanation from its supplemental questionnaire” and
“did not address in its comments the issue of annual average costs, the basis
for [Commerce’s] decision to recalculate its indirect conversion costs.” Remand Results
Court No. 24-00070 Page 7
at 9–10. Commerce highlighted that “Dongkuk cites nothing to justify Commerce’s noted
variations and instead asks the agency to continue to rely on its normal books and
records.” Id. at 11. Critically, Commerce also found that Dongkuk’s support of its own
methodology in its questionnaire responses was immaterial because the agency already
determined that Dongkuk’s books and records did not reasonably reflect the cost
of production. Id.
As to this litigation, Dongkuk argues for the same reasons it explained
to Commerce, and this court previously, that “no adjustment at all was warranted” as to
Dongkuk’s indirect conversion costs. Def.-Intervenor’s Opp’n Comments at 2. Further,
Dongkuk maintains that “[b]ecause [its] conversion costs reasonably reflected costs
associated with the production of wind towers, Commerce simply should have provided
further explanation, in response to the Court’s remand order, that no smoothing
adjustment to [Dongkuk’s] reported indirect conversion costs was warranted.” Id. at 4.
Dongkuk’s arguments relate solely to its view that “[Dongkuk’s] cost reporting
methodology was reasonable, and substantial evidence demonstrated that all direct and
indirect conversion costs inherently related to the production of merchandise and were
attributable to the finished towers’ physical attributes.” Id. It now asks the court to “reject
Commerce’s Remand Results and issue specific instructions that Commerce must
calculate a weighted-average dumping margin for DKSC using its indirect conversion
costs as reported.” Id. at 5.
Commerce explained that despite Dongkuk’s statement about indirect conversion
costs being the “same unit price per ton [ ] applied to all projects’ . . . [Commerce’s] review
Court No. 24-00070 Page 8
of Dongkuk’s recorded cost data demonstrates [that] this is not so.” Remand Results
at 4. Because Dongkuk’s records were found not to reasonably reflect the cost
of production, Commerce then turned to its “normal practice” of “rely[ing] on POR-annual
average costs to calculate a respondent’s cost of production.” Id. at 4–5 (citing Stainless
Steel Bar from the UK). In Commerce’s view, applying its “normal practice” of “rely[ing]
on POR-annual average costs to calculate a respondent’s cost of production” is the better
methodology to determine indirect conversion costs because it “would reduce the impact
of month-to-month fluctuations that are not reflective of either the actual costs to produce
the merchandise under consideration or the product characteristics.” Id. Regarding
Defendant-Intervenor’s comments, Defendant explains that “Dongkuk did not address
in its comments the issue of annual average costs, the basis for [Commerce’s] decision
to recalculate [Dongkuk’s] indirect conversion costs” and therefore “provided no basis
to deviate from [Commerce’s] approach in the Draft Remand.” Id. at 8.
Further, Defendant-Intervenor’s draft remand opposition comments and
its Remand Results opposition comments before this Court are limited to the sole
argument that its own preferred conversion cost methodology is supported by substantial
evidence. Defendant-Intervenor fails, however, to show that Commerce’s finding that
Dongkuk’s costs required adjustment is unreasonable. The court’s role, therefore, is to
determine whether Defendant-Intervenor can “demonstrate that Commerce acted
unreasonably.” Dongkuk S&C Co. v. United States, 134 F.4th 1320, 1331 (Fed. Cir.
2025). “Where we are faced with two opposing views of the record, it is the function of the
court to uphold Commerce’s determination if it is supported by substantial evidence.” Id.
Court No. 24-00070 Page 9
Presented with such circumstances here, the court shall sustain Commerce’s
determination on remand.
B. Commerce’s Decision Not to Adjust Dongkuk’s Direct Conversion Costs
When Commerce examined Dongkuk’s reported direct variable costs, it found that
“unlike its indirect conversion costs, [Dongkuk’s] direct VOH is ‘directly traceable and
assigned to the specific projects.’” Remand Results at 7. Commerce explained that
Dongkuk’s direct VOH costs traceability to specific projects eliminates the unexplained
variations found in Dongkuk’s monthly indirect conversion cost. Id. at 7–8. Accordingly,
Commerce did not adjust Dongkuk’s direct VOH conversion cost methodology, as it
reasonably reflects the cost of producing the merchandise. See 19 U.S.C.
§ 1677b(f)(1)(A).
Given the court’s holding that Commerce did not adequately address how three
product characteristics (weight, height, and tower sections) were reflected in Dongkuk’s
conversion costs, Commerce explains that “Dongkuk’s direct material costs, specifically
its steel plate costs, correspond to most of the physical differences in these product
characteristics.” Remand Results at 6. Commerce points out that because “weight and
height product characteristics are based on the wind tower’s dimensions; by extension,
most of the costs related to the differences in those product characteristics correspond
to the amount of steel plate used to produce a given wind tower.” Id. In Commerce’s
view, given the direct material costs’ (including steel plates) proportion of the overall cost
of manufacturing compared to conversion costs, direct material costs “most closely
Court No. 24-00070 Page 10
correspond to the differences in these physical characteristics, not the conversion costs.”
Id.
In its opposition comments, Plaintiff argued that Commerce’s Remand Results are
not supported by substantial evidence because Dongkuk’s direct VOH conversion costs
do not reasonably reflect the physical characteristics of its merchandise, and instead
should be adjusted to mirror Commerce’s indirect conversion cost analysis. Pl.’s Opp’n
Comments at 2. Specifically, Plaintiff argued that it is unreasonable for Commerce
to conclude that steel plate costs and project-specific costs are related to the physical
characteristics of the subject merchandise. In support, Plaintiff provided examples
of VOH costs that contradict Commerce’s conclusions that direct VOH costs correspond
to physical characteristics of its merchandise. Id. at 5. Plaintiff concludes that Commerce
should “make the same adjustment to direct VOH that it made to direct labor, indirect
VOH, and indirect fixed overhead.” Id. at 5.
Commerce disagreed that Dongkuk’s reported direct VOH costs should be
adjusted because the agency evaluated and determined that Dongkuk’s direct VOH costs
did not “suffe[r] from the same distortive allocation methodology as its indirect conversion
costs” and was “reasonably reflective of the product characteristics.” Remand Results
at 12. Commerce responded that despite Plaintiff’s contention “that Dongkuk’s reported
direct VOH is not reflective of the physical characteristics, . . . [Plaintiff] provides no basis
for this alleged mismatch” and that Commerce will not make “adjustments to a
respondent’s reported costs under section 773(f)(1)(A) of the Act,” where the
respondent’s reported costs reflect the physical characteristics and cost of production.
Court No. 24-00070 Page 11
Id. at 13. Regarding Plaintiff’s examples, Commerce argued that these comparisons
of specific CONNUMs are “granular,” unreasonable, “prone to cherry picking,” and do not
invalidate Commerce’s “wider set of cost data where the differences in complexity are
reflected in the aggregate.” Id. at 14. Commerce defended its selected direct VOH cost
methodology as “correspond[ing] to the complexity of the physical characteristics of
the different CONNUMs, despite the existence of CONNUMs that do not reflect that
relationship.” Id. at 15. Commerce looked at Plaintiff’s proposed examples and
disagreed, finding that “the differences in those product characteristics are accounted
for by the amount of steel plate consumed and the corresponding steel plate costs
reported.” Id. Commerce concluded by focusing on Plaintiff’s examples and explained
that those examples actually are: “consistent with [Commerce’s] findings,” display
reasonable variations, or do not consider Commerce’s finding that “weight and height of
the tower should be reflected in the steel plate and direct materials costs as opposed to
the conversion costs, including direct VOH.” Id. at 18. As a result, Commerce made no
changes from its Draft Results and filed its Remand Results.
Plaintiff now argues in this litigation that “Commerce has not explained why project-
specific cost reporting means that Dongkuk’s direct VOH costs reflect physical differences
in the merchandised produced” and that “Commerce did not account for unexplained
differences in direct variable overhead when it smoothed plate costs.” Pl.’s Opp’n
Comments at 3, 12. Plaintiff additionally argues that Commerce did not consider
the relationship between direct VOH costs and physical characteristics (such as height
and weight), and that Plaintiff’s CONNUM comparison examples show that Commerce’s
Court No. 24-00070 Page 12
analysis of weight, height, and internal complexity is unsupported by substantial evidence.
Id. at 5, 7.
The court disagrees. As an initial matter, Commerce noted that Dongkuk’s direct
VOH reported costs “are distinguishable from its reporting of indirect conversion costs.”
Remand Results at 13. Commerce explained that unlike Dongkuk’s reported indirect
conversion costs, Dongkuk’s direct VOH costs were directly traceable to projects,
recorded on a project-specific basis, and did not suffer from unexplained variations. Id.
at 12–13. Therefore, while Dongkuk’s indirect conversion costs did not reasonably reflect
the cost of producing wind towers, Dongkuk’s direct VOH costs were both recorded in
its normal books and records and reasonably reflected the cost of producing the wind
towers. See id. (citing 19 U.S.C. § 1677b(f)(1)(A)). Therefore, Commerce explained that
it had no reason to adjust Dongkuk’s direct VOH costs or smooth steel plate costs.
Plaintiff’s argument that Commerce failed to consider the relationship between
direct VOH, and weight and height product characteristics is similarly unpersuasive.
Commerce explained that height and weight characteristic differences are accounted
for in the steel plate costs and direct costs reported. Remand Results at 15. Commerce
therefore considered this argument and instead found that direct costs, not conversion
costs, more closely correspond to and account for the differences in weight and height.
Id. at 6.
Finally, the court rejects Plaintiff’s argument that Commerce’s analysis of weight,
height, and internal complexity is unsupported by substantial evidence. Pl.’s Opp’n
Comments at 7–9. Commerce explained on remand that Dongkuk’s direct VOH costs
Court No. 24-00070 Page 13
reasonably reflect the costs to produce wind towers because of patterns observed
between various characteristics of wind towers and the costs of producing the wind
towers. Remand Results at 7–8. Commerce acknowledged and provided explanations
for each of Plaintiff’s example outliers, and explained that despite these few outliers,
a “wider set of cost data where the differences in complexity are reflected in the
aggregate” better reflects the cost of producing wind towers. Id. at 14. The court is
mindful that “‘[w]here Commerce is confronted with two alternatives (both of which have
their good and bad qualities), and Commerce has a preferred alternative,’ substantial
evidence review means that [the court] ‘will not second-guess Commerce’s choice.’”
SeAh Steel VINA Corp. v. United States, 950 F.3d 833, 842–43 (Fed. Cir. 2020).
Accordingly, the court rejects Plaintiff’s arguments and will sustain Commerce’s
determination as to direct VOH costs.
IV. Conclusion
For the foregoing reasons, the court sustains Commerce’s Remand Results.
Judgment will be entered accordingly.
