A preliminary investigation by federal agencies has determined that phosphate salts from China have been dumped onto the U.S. market to the detriment of domestic producers.
Phosphate salts are used in fertilizers, pesticides and numerous other products.
The U.S. Department of Commerce and International Trade Commission have reached a preliminary finding that China has subsidized production of the chemicals, which have been sold into the U.S. at about 70 percent to 95 percent below the fair market value.
In March, the federal government began collecting duties on Chinese phosphate salts.
The rate was set at 109 percent of the product's value to countervail the subsidies, in addition to antidumping duties of 70 percent to 95 percent.
Final determinations are expected to be released by July.
