USITC Votes to Continue Investigation Concerning Sodium Sulfate Anhydrous from Canada

The United States International Trade Commission (USITC) today determined that there is a reasonable indication that a U.S. industry is materially injured by reason of imports of sodium sulfate anhydrous from Canada that are allegedly sold in the United States at less than fair value.

Commissioners Irving A. Williamson, Rhonda K. Schmidtlein, and Jason E. Kearns voted in the affirmative.  Chairman David S. Johanson and Commissioner Meredith M. Broadbent voted in the negative.

As a result of the Commission’s affirmative determination, the U.S. Department of Commerce will continue with its antidumping duty investigation concerning imports of this product from Canada, with its preliminary antidumping duty determination due on or about September 4, 2019.

The Commission’s public report Sodium Sulfate Anhydrous from Canada (Inv. No. 731-TA-1446 (Preliminary), USITC Publication 4895, May 2019) will contain the views of the Commission and information developed during the investigation.

The report will be available after June 10, 2019; when available, it may be accessed on the USITC website at:
