DONGKUK S&C CO., LTD. v. US, No. 23-1419 (Fed. Cir. 2025)
Annotate this Case
Dongkuk S&C Co., Ltd., a Korean producer of utility scale wind towers, challenged the United States Department of Commerce's final determination that its wind towers were being sold in the United States at less than fair value, resulting in an antidumping duty order. Commerce's investigation covered sales from July 1, 2018, to June 30, 2019, and found that Dongkuk's sales were below normal value, leading to the imposition of antidumping duties.
The Court of International Trade (CIT) initially remanded Commerce's decision to adjust Dongkuk's steel plate costs, questioning the analytical support for Commerce's determination. Commerce provided additional analysis on remand, demonstrating that the cost variations were due to the timing of steel plate purchases rather than the physical characteristics of the wind towers. The CIT subsequently sustained Commerce's remand redetermination and upheld the choice of surrogate financial data for calculating constructed value profit and selling expenses.
The United States Court of Appeals for the Federal Circuit reviewed the case and affirmed the CIT's decision. The court held that Commerce's determination to adjust Dongkuk's steel plate costs was supported by substantial evidence, as the cost variations were unrelated to the physical characteristics of the wind towers. Additionally, the court upheld Commerce's use of SeAH Steel Holdings Corporation's consolidated financial statement as a reasonable source of surrogate data for calculating constructed value profit and selling expenses, despite Dongkuk's preference for SeAH Steel Corporation's standalone financial data. The court found that Commerce's decision was reasonable and supported by substantial evidence.
