The Mosaic Co., Tampa, said June 26 that it is filing petitions with the U.S. Department of Commerce and the U.S. International Trade Commission that request the initiation of countervailing duty investigations into imports of phosphate fertilizers from Morocco and
Russia. It said the purpose of the petitions is to remedy the distortions that foreign subsidies are causing in the U.S. market for phosphate fertilizers, and thereby restore fair competition.
