Key quotations

Commerce concluded that “the overwhelming factor that caused the differences in the steel plate costs [for the final CONNUMs] was the timing of the steel plate purchases.” (13)
“Commerce’s choice of SSHC’s twelve‑month financial statement, almost entirely reflective of non‑steel, non‑Korean sales, is the better proxy than SeHC’s four‑month financial statement, reflective of only steel sales in Korea.” (16)

Factual background

Dongkuk S&C Co., Ltd. is a Korean producer of utility‑scale wind towers. Commerce investigated imports of those towers, found them sold at less than fair value, and issued a final antidumping duty order based on constructed value calculations that adjusted steel‑plate costs and used consolidated financial statements of SeAH Steel Holdings Corp. (SSHC) as surrogate data.

Procedural history

The CIT affirmed Commerce’s final determination that Dongkuk S&C Co. (DKSC) sold wind towers at less than fair value and imposed an antidumping duty. DKSC appealed, arguing Commerce erred in adjusting steel‑plate costs and in selecting surrogate financial data. The Federal Circuit reviewed the CIT’s decision for substantial‑evidence compliance.
