Methylene Diphenyl Diisocyanate (MDI) From China Injures U.S. Industry, Says USITC
The U.S. International Trade Commission (Commission or USITC) today determined that a U.S. industry is materially injured by reason of imports of methylene diphenyl diisocyanate (MDI) from China that the U.S. Department of Commerce (Commerce) has determined are sold in the United States at less than fair value.
Chair Amy A. Karpel and Commissioner Jason E. Kearns made affirmative determinations of present material injury. Commissioner David S. Johanson made an affirmative threat determination.
As a result of the Commission’s affirmative determination, Commerce will issue an antidumping duty order on imports of this product from China.
The Commission’s public report, Methylene Diphenyl Diisocyanate from China (Inv. No. 731-TA-1733 (Final), USITC Publication 5737, May 2026), will contain the views of the Commission and information developed during the investigation.
The report will be available by June 19, 2026; when available, it may be accessed on the USITC website.
