HS Code for Butadiene rubber

Butadiene rubber (BR) is classified under HS code 400220, which specifically designates synthetic butadiene rubber in primary forms or in plates, sheets, or strip. This classification is based on the material's synthetic origin, distinguishing it from natural rubber, and its chemical composition as a polymer derived predominantly from butadiene monomers. The "primary forms" typically refer to unvulcanized rubber in bales, crumbs, or liquids, as it is produced before further processing. The inclusion of "plates, sheets or strip" covers initial semi-finished forms of the synthetic rubber. Butadiene rubber is highly valued for its excellent abrasion resistance, low rolling resistance, and good elasticity, making it a critical component in various industrial applications, particularly in the automotive sector.

Common Misclassification

A common misclassification involves HS code 400219, which covers "Synthetic rubber; styrene-butadiene rubber (SBR), other than latex." While both BR and SBR are synthetic rubbers derived from butadiene, SBR is a copolymer of styrene and butadiene, whereas BR is primarily a homopolymer of butadiene. This compositional difference is critical for classification. Another potential confusion is with HS 4001, which covers "Natural rubber, balata, gutta-percha, guayule, chicle and similar natural gums, in primary forms or in plates, sheets or strip." Butadiene rubber is synthetic, not natural, making this distinction clear. Furthermore, HS 290124 covers "Buta-1,3-diene and isoprene," which are the monomers used to produce butadiene rubber, not the polymer itself. The polymer (rubber) is classified under Chapter 40.

FAQ
