Standard acrylonitrile-butadiene rubber (NBR) is classified under heading 4002 as a synthetic rubber. Hydrogenated NBR (HNBR), which undergoes additional catalytic hydrogenation to improve heat and chemical resistance, may be classified differently depending on its degree of hydrogenation and whether it meets the HTS definition of synthetic rubber. Importers of HNBR should consult a licensed customs broker or request a binding ruling to confirm the correct tariff line.
HTS 4002590000 covers NBR in primary forms or as plates, sheets, and strip that have not been further worked into finished or semi-finished articles. Once NBR sheet is cut to shape, vulcanized into gaskets, or otherwise processed into a specific article, it typically advances to a different HTS chapter (e.g., Chapter 40 headings covering rubber articles). The degree of further processing and the product's commercial identity at the time of importation are the key classification factors.
