CIT remands Commerce redeterminations on freight rail couplers from China

The U.S. Court of International Trade remanded Commerce's antidumping and countervailing redeterminations in the investigations of freight rail couplers from China, Court No. 23-00160 and Court No. 23-00161, in Slip Op. 26-122 dated October 8, 2026.

Commerce had continued to find on remand that attached couplers were properly included in the scope of the orders.

United States, Slip Op. 26-80, Court Nos. 25-00235 and 26-00825.
