The United States International Trade Commission (Commission or USITC) today determined there is a reasonable indication that a U.S. industry is materially injured by reason of imports of l-lysine (lysine) from China that are allegedly sold in the United States at less than fair value and subsidized by the government of China.

Chair Amy A. Karpel and Commissioners David S. Johanson and Jason E. Kearns voted in the affirmative.

As a result of the Commission’s affirmative determinations, the U.S. Department of Commerce will continue its investigations of imports of lysine from China, with its preliminary antidumping duty determination due on or about November 4, 2025, and its preliminary countervailing duty determination due on or about August 21, 2025.

The Commission’s public report, of L-lysine from China (Inv. Nos. 701-TA-767 and 731-TA-1750 (Preliminary), USITC Publication 5650, July 2025), will contain the views of the Commission and information developed during the investigations.

The report will be available by August 18, 2025; when available, it may be accessed on the USITC website.
