Court Decision Amends Antidumping Duty on Korean Wind Towers

Estimated reading time: 1–7 minutes

On September 4, 2026, the U.S. Court of International Trade (CIT) made a crucial decision about wind towers from Korea. This decision was not in agreement with the previous results from the U.S. Department of Commerce. The decision affects the antidumping duty review for the period from August 1, 2021, to July 31, 2022.

The Department of Commerce is now changing the results of that review. Dongkuk S&C Co., Ltd., a company from Korea, had to change how its dumping margin was calculated.

The Court of International Trade agreed with the new calculations for Dongkuk’s costs. This means the final dumping margin for Dongkuk is now slightly lowered. From a former rate of 1.95%, the new dumping margin is now 1.90%.

Even though the dumping margin has changed, Dongkuk won’t see a change in its current cash deposit rate. This is because there have been newer results since the 2021-2022 review.

Currently, the liquidation of Dongkuk’s entries is on hold by order of the court. If this decision is not appealed, or the appeal favors the court’s decision, Commerce will instruct U.S. Customs to assess antidumping duties accordingly.

This decision is an important update in the ongoing monitoring and regulation of international trade duties.
