Superabsorbent Polymers from South Korea Injures U.S. Industry, Says USITC

The United States International Trade Commission (USITC) today determined that a U.S. industry is materially injured by reason of imports of superabsorbent polymers from South Korea that the U.S. Department of Commerce (Commerce) has determined are sold in the United States at less than fair value.

Chairman David S. Johanson and Commissioners Rhonda K. Schmidtlein, Jason E. Kearns, Randolph J. Stayin, and Amy A. Karpel voted in the affirmative. 

As a result of the Commission’s affirmative determination, Commerce will issue an antidumping duty order on imports of this product from South Korea.

The Commission’s public report Superabsorbent Polymers from South Korea (Inv. No. 731-TA-1574 (Final), USITC Publication 5388, December 2022) will contain the views of the Commission and information developed during the investigation.

The report will be available by January 2, 2023; when available, it may be accessed on the USITC website at:
