Industrial Isoprene from C5 Raffinate
Industrial isoprene extracted from C5 petroleum cracker streams, with 95-97% purity, is used as a monomer in polyisoprene rubber production. It qualifies as a separate chemically defined organic compound under Chapter 29 note 1(a), despite its raffinate origin. This tariff item covers buta-1,3-diene and isoprene as acyclic unsaturated hydrocarbons.
