CIT sustains Commerce remand results in wind towers AD review of Dongkuk S&C

The U.S. Court of International Trade sustained Commerce's remand results in the antidumping duty administrative review of utility scale wind towers from the Republic of Korea, Slip Op. 26-104, Court No. 24-00070, in an opinion by Judge Leo M. Gordon dated September 4, 2026. On remand Commerce reconsidered Dongkuk S&C Co., Ltd.'s indirect conversion costs, found its reported methodology distortive, and recalculated the weight-average dumping margin to 1.90 percent. The court sustained Commerce's use of period-of-review annual average costs over Dongkuk's reported indirect conversion costs.
