The Ministry of Commerce said it is imposing tariffs of up to 36% on nylon 6 or polycaprolactam from the US, because imports have damaged the domestic industry the Wall Street Journal reported. Nylon 6 is used in a number of products including toothbrushes, gun frames and chiffon. The antidumping measure is the latest in a series of trade measures introduced by China after Washington last month said it would impose duties of between 25% and 35% on imports of tires from China for the next three years. Importers of nylon 6 will be required to pay a deposit if they purchase the product from foreign companies judged to be selling the product at an unfair price. Companies effected include the US arm of German chemical giant BASF which was levied with a 30.4% duty, and Honeywell Resins & Chemical, a part of Honeywell International, levied with a 36.2% duty.
