**SUPPLEMENTARY INFORMATION:**
**Background**
On August 31, 2012, Commerce published in the *Federal Register* the antidumping duty order on large power transformers from Korea. [^1] On September 20, 2024, based on timely requests for review, Commerce initiated this administrative review covering four companies. [^2] We selected two mandatory respondents in this review, HD Hyundai Electric Co., Ltd. and Iljin Electric Co., Ltd. [^3]

[^2]*See Initiation of Antidumping and Countervailing Duty Administrative Reviews,* 89 FR 77079, 77081 (September 20, 2024) ( *Initiation Notice* ).
[^3]*See* Memorandum, “Respondent Selection,” dated October 30, 2024.
On December 9, 2024, Commerce tolled certain deadlines in this administrative review by 90 days. [^4] Further, due to the lapse in appropriations and Federal Government shutdown, on November 14, 2025, Commerce tolled all deadlines in administrative proceedings by 47 days. [^5] Additionally, due to a backlog of documents that were electronically filed via Enforcement and Compliance's Antidumping and Countervailing Duty Centralized Electronic Service System (ACCESS) during the Federal Government shutdown, on November 24, 2025, Commerce tolled all deadlines in administrative proceedings by an additional 21 days. [^6] On July 16, 2025, and January 7, 2026, we extended the deadline for issuing the preliminary results of this review. [^7] Accordingly, the deadline for these preliminary results is now February 5, 2026.

**Scope of the Order**
The merchandise subject to the *Order* is large power transformers from Korea. For a complete description of the scope of the *Order, see* the Preliminary Decision Memorandum.
**Methodology**
Commerce is conducting this review in accordance with section 751(a) of the Tariff Act of 1930, as amended (the Act). Constructed export prices have been calculated in accordance with section 772(b) of the Act. Normal value is calculated in accordance with section 773 of the Act. For a full description of the methodology underlying these preliminary results, *see* the Preliminary Decision Memorandum.
**Rate for Non-Selected Respondents**
The Act and Commerce's regulations do not address the rate to be applied to companies not selected for individual examination when Commerce limits its examination in an administrative review pursuant to section 777A(c)(2) of the Act. Generally, Commerce looks to section 735(c)(5) of the Act, which provides instructions for calculating the all-others rate in a less-than-fair-value (LTFV) investigation, for guidance when calculating the rate for companies which were not selected for individual examination in an administrative review. Under section 735(c)(5)(A) of the Act, the all-others rate is normally an amount equal to the weighted average of the estimated weighted average dumping margins established for exporters and producers individually investigated, excluding any zero or *de minimis* margins, and any margins determined entirely on the basis of facts available.
Where the weighted-average dumping margins for individually examined respondents are zero, *de minimis,* or determined based entirely on facts available, section 735(c)(5)(B) of the Act provides that Commerce may use “any reasonable method to establish the estimated all-others rate for exporters and producers not individually investigated . . .” In this review, Commerce preliminarily calculated a weighted-average dumping margin of zero percent for HD Hyundai Electric Co., Ltd. and Iljin Electric Co., Ltd. Therefore, we have preliminarily determined to continue to assign the estimated weighted-average dumping margins currently in effect to the non-selected companies subject to review. For a full discussion of the rates for non-selected companies, *see* the Preliminary Decision Memorandum.
**Preliminary Results of Review**
Commerce preliminarily determines that the following estimated weighted-average dumping margins exist during the period August 1, 2023, through July 31, 2024:
| Producer/exporter | Weighted-average dumping margin |
| --- | --- |
| HD Hyundai Electric Co., Ltd | 0.00 |
| Iljin Electric Co., Ltd | 0.00 |
| LS Electric Co., Ltd | 16.87 |
| Hyosung Heavy Industries Corporation | 4.32 |
**Disclosure**
Commerce intends to disclose its calculations performed to interested parties for these preliminary results within five days of any public announcement or, if there is no public announcement, within five days of the date of publication of this notice in accordance with 19 CFR 351.224(b).
**Public Comment**
Case briefs or other written comments may be submitted to the Assistant Secretary for Enforcement and Compliance. Pursuant to 19 CFR 351.309(c)(1)(ii), we have modified the deadline for interested parties to submit case briefs to Commerce to no later than 21 days after the date of the publication of this notice. [^9] Rebuttal briefs, limited to issues raised in the case briefs, may be filed not later than five days after the date for filing case briefs. [^10] Interested parties who submit case briefs or rebuttal briefs in this proceeding must submit: (1) a table of contents listing each issue; and (2) a table of authorities. [^11]
[^9] Commerce is exercising its discretion under 19 CFR 351.309(c)(1)(ii) to alter the time limit for the filing of case briefs. *See* 19 CFR 351.309(c)(1)(ii).
[^10]*See* 19 CFR 351.309(d); *see also Administrative Protective Order, Service, and Other Procedures in Antidumping and Countervailing Duty Proceedings,* 88 FR 67069, 67077 (September 29, 2023) ( *APO and Service Final Rule* ).
[^11]*See* 19 351.309(c)(2) and (d)(2).
As provided under 19 CFR 351.309(c)(2)(iii) and (d)(2)(iii), we request that interested parties provide at the beginning of their briefs a public, executive summary for each issue raised in their briefs. [^12] Further, we request that interested parties limit their executive summary of each issue to no more than 450 words, not including citations. We intend to use the executive summaries as the basis of the comment summaries included in the issues and decision memorandum that will accompany the final results in this administrative review. We request that interested parties include footnotes for relevant citations in the executive summary of each issue.
[^12] We use the term “issue” here to describe an argument that Commerce would normally address in a comment of the Issues and Decision Memorandum.
Pursuant to 19 CFR 351.310(c), interested parties who wish to request a hearing must submit a written request to the Assistant Secretary for Enforcement and Compliance, filed electronically via ACCESS. by 5:00 p.m. Eastern Time within 30 days after the date of publication of this notice. Requests should contain: (1) the party's name, address, and telephone number; (2) the number of participants, and whether any participant is a foreign national; and (3) a list of issues to be discussed.

[^14]*See* 19 CFR 351.303.
[^15]*See APO and Service Final Rule,* 88 FR at 67069.
**Assessment Rates**
Upon issuing the final results, Commerce shall determine, and CBP shall assess, antidumping duties on all appropriate entries. Pursuant to 19 CFR 351.212(b)(1), for any individually examined respondent whose weighted-average dumping margin is not zero or *de minimis* ( *i.e.,* less than 0.5 percent) in the final results of this review, we intend to calculate importer-specific *ad valorem* assessment rates based on the ratio of the total amount of antidumping duties calculated for the examined sales to the total entered value of those same sales. If any respondent's weighted-average dumping margin in the final results is zero or *de minimis* within the meaning of 19 CFR 351.106(c)(1), or an importer-specific rate is zero or *de minimis* within the meaning of 19 CFR 351.106(c)(2), we will instruct CBP to liquidate the appropriate entries without regard to antidumping duties.
Commerce's “automatic assessment” practice will apply to entries of subject merchandise during the POR produced by each respondent for which it did not know that the merchandise it sold was destined for the United States. In such instances, we will instruct CBP to liquidate those entries at the all-others rate established in the original LTFV investigation ( *i.e.,* 22.00 percent), [^16] if there is no rate for the intermediate company(ies) involved in the transaction. [^17]
[^16]*See Order,* 77 FR 53177.
[^17]*See Large Power Transformers from the Republic of Korea: Final Determination of Sales at Less Than Fair Value,* 77 FR 40857 (July 11, 2012).
For LS Electric Co., Ltd. and Hyosung Heavy Industries Corporation, the companies that were not selected for individual examination, we intend to assign an assessment rate equal to the weighted average dumping margins calculated in the final results of this review for the companies selected for mandatory review, unless that rate is zero or *de minimis,* in which case we intend to instruct CBP to liquidate relevant entries at dumping margins currently in effect.
In accordance with section 751(a)(2)(C) of the Act, the final results of this review shall be the basis for the assessment of antidumping duties on entries of merchandise covered by the final results of this review and for future deposits of estimated duties, where applicable. Commerce intends to issue assessment instructions to CBP no earlier than 35 days after the date of publication of the final results of this review in the *Federal Register* . If a timely summons is filed at the U.S. Court of International Trade, the assessment instructions will direct CBP not to liquidate relevant entries until the time for parties to file a request for a statutory injunction has expired ( *i.e.,* within 90 days of publication).
**Cash Deposit Requirements**
The following cash deposit requirements will be effective for all shipments of the subject merchandise entered, or withdrawn from warehouse, for consumption on or after the publication date of the final results of this administrative review, as provided by section 751(a)(2)(C) of the Act: (1) the cash deposit rate for the companies listed above will be that established in the final results of this review, except if the rate is less than 0.50 percent and, therefore, *de minimis* within the meaning of 19 CFR 351.106(c)(1), in which case the cash deposit rate will be zero; (2) for previously investigated or reviewed companies not covered in this review, the cash deposit rate will continue to be the company-specific cash deposit rate published for the most recently completed segment of this proceeding in which the company participated; (3) if the exporter is not a firm covered in this review, or the LTFV investigation, but the manufacturer is, then the cash deposit rate will be the rate established for the most recent segment for the manufacturer of the merchandise; and (4) the cash deposit rate for all other manufacturers or exporters will continue to be 22.00 percent, the all-others rate established in the LTFV investigation. [^18] These cash deposit requirements, when imposed, shall remain in effect until further notice.
[^18]*See Order,* 77 FR 53177.
**Final Results of the Review**
Unless otherwise extended, Commerce intends to issue the final results of this administrative review, including the results of its analysis of the issues raised in any written briefs, no later than 120 days after the date of publication of this notice in the *Federal Register**,* pursuant to section 751(a)(3)(A) of the Act and 19 CFR 351.213(h)(1).
**Notification to Importers**
This notice serves as a preliminary reminder to importers of their responsibility under 19 CFR 351.402(f)(2) to file a certificate regarding the reimbursement of antidumping and/or countervailing duties prior to liquidation of the relevant entries during this POR. Failure to comply with this requirement could result in Commerce's presumption that reimbursement of antidumping duties occurred and the subsequent assessment of double antidumping duties.
**Notification to Interested Parties**
Commerce is issuing and publishing this notice in accordance with sections 751(a)(1) and 777(i)(1) of the Act, 19 CFR 351.213(h)(2), and 19 CFR 351.221(b)(4).
