The United States International Trade Commission (Commission or USITC) today determined there is a reasonable indication that a U.S. industry is materially injured due to imports of tris(hydroxymethyl)aminomethane and tris(hydroxymethyl)aminomethane hydrochloride (“Tris and Tris HCl") 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 Tris and Tris HCl from China.

The Commission’s public report, Tris(hydroxymethyl)aminomethane and Tris(hydroxymethyl)aminomethane hydrochloride (“Tris and Tris HCl") from China (Inv. Nos. 701-TA-793 and 731-TA-1789 (Preliminary), USITC Publication 5751, June 2026), will contain the views of the Commission and information developed during the investigations.

The report will be available on the USITC website by July 10, 2026.
