No Duties on Korean Wind Towers: Review Clears Dongkuk
Published Date: 9/30/2026
Notice
Summary
The U.S. Department of Commerce found that Dongkuk S&C from Korea didn’t sell wind towers at unfairly low prices between August 2024 and July 2025. They also stopped reviewing eight other companies in this case. This means no extra duties for Dongkuk right now, and the decision kicks in starting September 30, 2026.
Analyzed Economic Effects
5 provisions identified: 1 benefits, 3 costs, 1 mixed.
Dongkuk preliminarily found no dumping
Commerce preliminarily determined that Dongkuk S&C Co., Ltd. had a weighted-average dumping margin of 0.00 percent for the period August 1, 2024 through July 31, 2025. This preliminary result (published September 30, 2026) means Dongkuk is not subject to antidumping duties for those reviewed sales if the final results remain zero or de minimis.
Importer duty-reimbursement certificate requirement
Importers must file a certificate about reimbursement of antidumping duties under 19 CFR 351.402(f) prior to liquidation of relevant entries during this review period. If you (the importer) do not file this certificate, Commerce may presume reimbursement occurred and assess double antidumping duties.
Review rescinded for eight Korean firms
Commerce rescinded the administrative review for eight named companies (CS Wind Corporation; Enercon Korea Inc.; Hyosung Heavy Industries; Nordex SE; Siemens Gamesa Renewable Energy; Unison Co., Ltd; Vestas Korea Wind Technology Ltd.; Win&P., Ltd.) because there were no reviewable, suspended entries during August 1, 2024 through July 31, 2025. Commerce will instruct U.S. Customs and Border Protection to assess antidumping duties on appropriate entries for these companies at the cash deposit rate required at the time of entry.
How duties will be assessed in final results
If Dongkuk's final weighted-average dumping margin is not zero or de minimis (i.e., not less than 0.50 percent), Commerce will calculate importer-specific assessment rates based on the ratio of dumping to entered value or per-unit basis; if the final margin is zero or de minimis, Commerce will instruct CBP to liquidate appropriate entries without regard to antidumping duties. Commerce intends to issue assessment instructions for Dongkuk no earlier than 35 days after publication of the final results.
Cash deposit rules and the all-others rate
For shipments entered, or withdrawn from warehouse for consumption, on or after the publication date of the final results, cash deposit rates will follow the final results: the company-specific rate for the reviewed firm unless that rate is less than 0.50 percent (in which case the cash deposit rate will be zero). For exporters/manufacturers not covered, the 'all-others' deposit rate remains 5.41 percent from the original investigation.
