Methionine from Japan and Spain 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 methionine from Japan and Spain that the U.S. Department of Commerce (Commerce) has determined are sold in the United States at less than fair value.

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

As a result of the Commission’s affirmative determinations, Commerce will issue antidumping duty orders on imports of this product from Japan and Spain.

The Commission also made a negative critical circumstances finding with regard to imports of this product from Spain.  As a result, these imports will not be subject to retroactive antidumping duties.

The Commission’s public report Methionine from Japan and Spain (Inv. Nos. 731-TA-1535-1536 (Final), USITC Publication 5230, September 2021) will contain the views of the Commission and information developed during the investigations.

The report will be available by September 28, 2021; when available, it may be accessed on the USITC website at:
