U.S. Department of Commerce Maintains Antidumping Duty on Potassium Phosphate Salts from China

Estimated reading time: 2–4 minutes

The United States Department of Commerce has made a significant decision regarding potassium phosphate salts imported from China. The decision comes as part of an “expedited third sunset review” related to the antidumping duty order on these salts. The Department has determined that removing the antidumping duty on this product could result in continued dumping of the product in the U.S. market. Dumping occurs when a foreign company sells a product in the U.S. at a price lower than fair value. This decision means that the current antidumping duties will remain in place.

The decision was officially recorded in the Federal Register on October 5, 2026. The document notes that there is a risk of Chinese manufacturers continuing to undercut U.S. prices if the duties are removed. The dumping margins, which indicate the extent of underpricing, could reach up to 95.40%. This figure suggests that without duties, potassium phosphate salts from China could be sold for significantly less than their fair value, harming U.S. producers.

The International Trade Administration, a division of the U.S. Department of Commerce, conducted the review. ICL Specialty Products Inc. and Prayon, Inc., both U.S.-based companies that produce similar products, participated in the review. They claimed that removing the antidumping duties would harm the U.S. industry.

The process began earlier in June 2026, with a notice of intent to review the existing order. Following a substantive response from domestic producers and a lack of response from foreign respondents, the department conducted an expedited review process. This quick review helped determine the final outcome, ensuring that the current duties remain to protect the U.S. market.

In conclusion, this decision underscores the Department of Commerce’s commitment to counter unfair trade practices and support domestic industries. The continued enforcement of antidumping duties will help maintain fair competition in the U.S. market for potassium phosphate salts.
