Ammonium Sulfate from China 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 ammonium sulfate from China that the U.S. Department of Commerce (Commerce) has determined are subsidized and sold in the United States at less than fair value.

Chairman Rhonda K. Schmidtlein, Vice Chairman David S. Johanson, and Commissioners Irving A. Williamson, Meredith M. Broadbent, and F. Scott Kieff voted in the affirmative.  Commissioner Dean A. Pinkert did not participate in these investigations.

As a result of the USITC’s affirmative determinations, Commerce will issue antidumping and countervailing duty orders on imports of this product from China.

The Commission’s public report Ammonium Sulfate from China (Investigation Nos. 701-TA-562 and 731-TA-1329 (Final), USITC Publication 4671, March 2017) will contain the views of the Commission and information developed during the investigations.

The report will be available by March 23, 2017; when available, it may be accessed on the USITC website at:
