Tyre imports from China will be slapped with heavier duties by the U.S Department of Commerce.
In a preliminary decision on Wednesday, Commerce set anti-dumping duties of up to 87.99 percent on car and light truck tires.
Commerce had already set anti-subsidy duties of up to 81.29 percent after a complaint from U.S. trade unions.
The duties will affect goods from 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, although Giti products will have lower duties of 19.17 percent.
In 2013, imports of passenger vehicle and light truck tires from China were worth about $2.1 billion.
A final Commerce Department ruling on duties is due by June 11 and by the International Trade Commission in July.
