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 polytetramethylene ether glycol from China, South Korea, Taiwan, and Vietnam that are allegedly sold in the United States at less than fair value.

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 determination, the U.S. Department of Commerce will continue its investigations of imports of polytetramethylene ether glycol from China, South Korea, Taiwan, and Vietnam.

The Commission’s public report, Polytetramethylene Ether Glycol from China, South Korea, Taiwan, and Vietnam (Inv. Nos. 731-TA-1782-1785 (Preliminary), USITC Publication 5746, 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 June 30, 2026.
