WASHINGTON - The United States on Friday imposed duties on certain automobile and light truck tires imported from China after finding they were being dumped at below-market value and unfairly subsidized by Beijing. In a final decision, Commerce Department set duties exceeding 100 percent in some cases. The duties will affect goods from companies including Shandong Yongsheng Rubber Group Co, Cooper Kunshan Tire Co, a subsidiary of Cooper Tire & Rubber Co, and Giti Tire (Fujian) Co, a subsidiary of Giti Tire. In 2014, imports of passenger vehicle and light truck tires from China were worth about $2.3 billion. The duties are still subject to a final decision by the U.S. International Trade Commission, which is due in July.
