Samples were submitted and sent for laboratory analysis. Item 1, “PE Film” is described as a thin microporous sheet of polyethylene film.  The film is used as a lithium-ion battery separator. Its purpose is to physically block direct contact between the anode and cathode in the lithium-ion battery. It is a secondary battery component that prevents fire and explosion. It will be imported on a roll. Item 2, “Coated PE film” is described as a thin microporous sheet of polyethylene film. The film is coated with boehmite, a mixture of aluminum oxide hydroxide and binder. The film is used as a lithium-ion battery separator. Its purpose is to physically block direct contact between the anode and cathode in the lithium-ion battery. It is a secondary battery component that prevents fire and explosion. The presence of the coating is said to improve thermal stability and wettability. It will be imported on a roll. CBP Laboratory Report NY20221340 confirms that both samples are microporous sheets of polyethylene film. It further indicates that the sample labeled as “Coated PE Film” is coated with the boehmite. The applicable subheading for the microporous polyethylene sheets will be 3921.19.0000, Harmonized Tariff Schedule of the United States (HTSUS), which provides for other plates, sheets, film, foil and strip: of plastics: cellular: of other plastics.  The general rate of duty will be 6.5 percent ad valorem. Pursuant to U.S. Note 20 to Subchapter III, Chapter 99, HTSUS, products of China classified under subheading 3921.19.0000, HTSUS, unless specifically excluded, are subject to an additional 25 percent ad valorem rate of duty.
