USITC Votes to Continue Investigations on Dioctyl Terephthalate (DOTP) From Malaysia, Poland, Taiwan, and Turkey

The United States International Trade Commission (USITC) today determined that there is a reasonable indication that a U.S. industry is subject to material injury by reason of imports of dioctyl terephthalate (DOTP) from Malaysia, Poland, Taiwan, and Turkey that are allegedly sold in the United States at less than fair value.

Chairman David S. Johanson and Commissioners Rhonda K. Schmidtlein, Jason E. Kearns, and Amy A. Karpel 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 DOTP from Malaysia, Poland, Taiwan, and Turkey, with its preliminary antidumping duty determinations due on or about September 2, 2024.

The Commission’s public report Dioctyl Terephthalate (DOTP) from Malaysia, Poland, Taiwan, and Turkey (Inv. Nos. 731-TA-1675-1678 (Preliminary), USITC Publication 5505, May 2024) will contain the views of the Commission and information developed during the investigations.

The report will be available by June 6, 2024; when available, it may be accessed on the USITC website at:
