Products classified under HTS 4002.19.00.20
High-Styrene SBR Latex
A liquid dispersion of styrene-butadiene rubber (SBR) containing over 50 percent styrene by weight in the dry polymer, used in primary form for coatings and adhesives. This falls under HTS 4002.19.00.20 as a synthetic rubber in primary liquid form meeting the styrene content and vulcanization criteria of Chapter 40 notes. It retains its essential character as raw material without prohibited compounding agents.
Styrene-Rich XSBR Paste
Carboxylated styrene-butadiene rubber (XSBR) paste with over 50% styrene by weight, supplied in primary paste form for enhanced adhesion in paper coatings. Classified in HTS 4002.19.00.20 due to its synthetic rubber composition, high styrene level, and primary form without disallowed modifications per chapter notes. Ideal for industrial binding applications.
Polystyrene-Modified SBR Granules
Granular synthetic rubber mixture of SBR with over 50 percent styrene content by dry weight, in bulk primary form for tire compounding. HTS 4002.19.00.20 applies as it meets synthetic rubber vulcanization test, high styrene spec, and excludes textiles/electrical per chapter exclusions. Used as raw input for rubber vulcanization.
High-Styrene SBR Powder
Fine powder form of SBR containing over 50% styrene by dry polymer weight, classified as primary bulk form for sprayable coatings. Fits HTS 4002.19.00.20 under synthetic rubbers in primary forms (note 3(b)), with no prohibited additives affecting raw character. Excluded from textiles or chapter 39 per notes.
XSBR High-Styrene Dispersion
Prevulcanized XSBR dispersion with >50% styrene, in liquid primary form for dipping compounds in glove production. HTS 4002.19.00.20 covers this as carboxylated SBR meeting chapter definitions, primary liquid (note 3(a)), usable as raw rubber input.
Styrene-Heavy SBR Crumbs
