USITC Votes to Continue Investigation on Methylene Diphenyl Diisocyanate (MDI) from China

The U.S. International Trade Commission (Commission or USITC) today determined that there is a reasonable indication that a U.S. industry is materially injured by reason of imports of methylene diphenyl diisocyanate (MDI) from China that are allegedly sold in the United States at less than fair value from 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 determination, the U.S. Department of Commerce will continue its investigations of MDI from China, with its preliminary antidumping duty determination for China due on or about July 22, 2025.

The Commission’s public report, Methylene Diphenyl Diisocyanate from China (Inv. No 731-TA-1733 (Preliminary), USITC Publication 5606, April 2025), will contain the views of the Commission and information developed during the investigations.

The report will be available by May 5, 2025; when available, it may be accessed on the USITC website.
