U.S. Preliminarily Finds Wind Towers From South Korea Sold Below Fair Market Value
Estimated reading time: 3–5 minutes
On January 23, 2026, the U.S. Department of Commerce announced preliminary results in the 2023–2024 antidumping duty administrative review of utility scale wind towers imported from the Republic of Korea.
The review covers the period from August 1, 2023, to July 31, 2024.
Commerce found that one company, Dongkuk S&C Co., Ltd., sold utility scale wind towers in the United States at prices below normal value. The preliminary weighted-average dumping margin for Dongkuk is 4.99 percent.
This means Dongkuk may face additional import duties of 4.99 percent when the final results are issued.
Commerce is also rescinding the review for eight South Korean companies. These companies did not have entries of wind towers in the United States during the review period. Because no merchandise was imported from them during the review period, no further review will take place for these firms.
The eight companies removed from the review are:
- CS Wind Corporation
- Enercon Korea Inc.
- Hyosung Heavy Industries
- Nordex SE
- Siemens Gamesa Renewable Energy Limited
- Unison Co., Ltd.
- Vestas Korea Wind Technology Ltd.
- Win&P., Ltd.
Commerce used data reported by Dongkuk to calculate the dumping margin. They used export price methods based on U.S. law – Sections 751(a), 772, and 773 of the Tariff Act of 1930.
All information used to reach these results is available in the Preliminary Decision Memorandum. The document can be found online at https://access.trade.gov.
Parties affected by this decision can submit case briefs no later than 21 days after this notice is published. Rebuttal briefs may be filed five days later. Hearings, if requested, must be asked for within 30 days of publication.
Commerce stated that the final results will be released no later than 120 days after the publication of this preliminary notice.
Commerce intends to assess duties on affected entries after the final results are published. If the final margin remains above 0.50 percent, CBP will collect duties using the calculated margin. If the margin is below 0.50 percent, no duties will be collected.
The cash deposit rate for Dongkuk will also change once final results are entered. For exporters not covered in this review, the previously assigned rates will continue to apply.
The all-others dumping margin from the original investigation remains at 5.41 percent.
Commerce reminds importers to submit certificates about any reimbursements of duties. Failure to do so could result in penalties, including double duties.
This review is part of ongoing enforcement of the Antidumping Duty Order issued in August 2020, originally published in 85 FR 52546. The review is conducted under the authority of the Department of Commerce, International Trade Administration, Enforcement and Compliance office.
