Estimated reading time: 5–9 minutes

On February 10, 2026, the U.S. Department of Commerce published preliminary results for the administrative review of the antidumping duty order covering large power transformers from the Republic of Korea. The review covers the period from August 1, 2023, through July 31, 2024.

Commerce preliminarily found that HD Hyundai Electric Co., Ltd. and Iljin Electric Co., Ltd. did not sell large power transformers in the United States at less than normal value. Their preliminary weighted-average dumping margins are 0.00 percent.

Two other companies, LS Electric Co., Ltd. and Hyosung Heavy Industries Corporation, were reviewed but not selected for individual examination. Their estimated weighted-average dumping margins are 16.87 percent and 4.32 percent, respectively.

Background

The original antidumping duty order on large power transformers from Korea was published on August 31, 2012 (77 FR 53177).

Commerce began this current administrative review on September 20, 2024 (89 FR 77079), after receiving timely requests for review. From the four companies covered, two were selected as mandatory respondents: HD Hyundai Electric Co., Ltd. and Iljin Electric Co., Ltd.

Administrative Deadline Adjustments

Commerce tolled deadlines on the following dates:

  • December 9, 2024: 90 days
  • November 14, 2025: 47 days, due to a Federal shutdown
  • November 24, 2025: 21 additional days, due to document backlog

Preliminary results were extended on July 16, 2025, and again on January 7, 2026. The publication date for preliminary results was set for February 5, 2026.

Scope of the Order

The product in question is large power transformers shipped from the Republic of Korea. A detailed scope description is available in the Preliminary Decision Memorandum, accessible at https://access.trade.gov.

Rate for Non-Selected Respondents

For companies not selected for individual review, such as LS Electric and Hyosung Heavy Industries, Commerce will continue assigning the existing estimated weighted-average dumping margins. These are based on previous segments unless changed in the final results.

Methodology

Commerce conducted this review under section 751(a) of the Tariff Act of 1930. Constructed export prices and normal values were calculated following sections 772(b) and 773 of the Act. Full details are in the Preliminary Decision Memorandum available via ACCESS.

Preliminary Dumping Margins

  • 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%

Public Comment

Case briefs from interested parties are due no later than 21 days after publication in the Federal Register. Rebuttal briefs, limited to issues raised in case briefs, must be filed within five days after the case brief deadline.

Briefs must:

  • Contain a table of contents and a table of authorities
  • Include public executive summaries of each issue, limited to 450 words each with citations

Hearing requests must be submitted within 30 days of publication. Requests must include contact information, number of participants, foreign national status, and list of issues.

All filings must be made via ACCESS per 19 CFR 351.303. Electronic submissions are due by 5:00 p.m. Eastern Time.

Assessment Rates

Upon completion of the final results, U.S. Customs and Border Protection (CBP) will be instructed to assess duties accordingly.

  • If dumping margins are zero or de minimis (less than 0.5 percent), CBP will be instructed to liquidate entries without duties.
  • For entries where the manufacturer was unaware of U.S. destination, CBP will assess duties at the all-others rate from the LTFV investigation (22.00 percent), unless another rate applies.

For companies not individually examined, Commerce will assign a rate based on the final margins of mandatory respondents. If the final margins remain zero or de minimis, entries will be liquidated without duties.

Final Results

The final results are due within 120 days of publication of this notice, unless extended. These results will determine future cash deposit rates and duty assessments.

Cash Deposit Requirements

Upon publication of the final results:

  • Companies with non-de minimis final margins will follow the new rates.
  • If the rate is less than 0.5 percent, the rate will be zero.
  • Other companies will continue to use their previously established cash deposit rates.
  • If the exporter is new but the manufacturer has a rate, the manufacturer’s rate applies.
  • All others: 22.00 percent, as set in the original LTFV order.

Notice to Importers

Importers must file a reimbursement certificate for antidumping duties before liquidation, as required in 19 CFR 351.402(f)(2). Noncompliance may result in double duties.

Next Steps

Commerce is accepting public comments and intends to publish the final results after reviewing all submissions. Assessment instructions will be issued no earlier than 35 days after publication of the final results.
