Styrene-Butadiene Rubber (SBR) Latex from China
SBR latex is a water-based dispersion of styrene-butadiene copolymer, used in adhesives, paper coatings, and carpet backings. It falls under HTS 4002.19.00 as a synthetic rubber in primary liquid form, meeting the vulcanization and elasticity criteria of chapter note 2 without prohibited compounding agents. This classification applies to prevulcanized or unvulcanized dispersions suitable for further processing.

Import Tips
• Verify latex concentration and styrene-butadiene ratio via lab testing to confirm synthetic rubber status; ensure no vulcanizing agents beyond permitted additives per chapter note 5
• Provide manufacturer specs showing compliance with elasticity tests; watch for misclassification as compounded mixtures
