U.S. Customs and Border Protection (CBP) announced a set of reclassification rulings in the January 20, 2016 edition of Customs Bulletin and Decisions that resulted in elimination of the tariff applicable to braking system parts. CBP reclassified various hydraulic braking system parts used in motor vehicles, with two of the changes resulting in the elimination of 2.9% tariffs by treating the items in question under duty-free subheadings. These include brake wheel cylinders that are now classified under HTSUS 8412.21.00 rather than 8708.39.5050, and caliper pistons that are now classified under HTSUS 8412.90.90 rather than 8708.39.5050. Brazil, China, Germany, Korea, Italy, Mexico, and Spain are the principal suppliers of this product. The final revocation and modification became effective for goods entered or withdrawn from warehouse for consumption on or after March 21, 2016.
