Styrene-Butadiene Rubber (SBR) Latex
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.
Carboxylated Styrene-Butadiene Rubber (XSBR) Dispersion
XSBR is an SBR variant with carboxylic acid groups for improved adhesion, supplied as aqueous paste for tire cord dipping and foam production. Classified in HTS 4002.19.00 as it retains synthetic rubber character in primary paste form without disallowed fillers or extenders. Essential for applications needing bonding enhancement.
SBR Crumb Rubber (Hot Polymerized)
Hot SBR crumbs are granular primary forms from high-temperature emulsion polymerization, ideal for tire treads and conveyor belts. HTS 4002.19.00 covers these bulk forms as they qualify as synthetic rubber per chapter notes, uncompounded except for allowed stabilizers. Provides balanced abrasion resistance.
Cold Polymerized SBR Granules
Cold SBR granules offer higher molecular weight for superior tire performance, supplied in bulk powder/granule form. Under HTS 4002.19.00 as primary synthetic rubber granules meeting elasticity recovery tests, free of vulcanizing agents. Preferred for premium automotive applications.
XSBR Powder for Adhesives
Spray-dried XSBR powder from latex, used in pressure-sensitive adhesives and textile coatings. HTS 4002.19.00 applies to this primary powder form of carboxylated synthetic rubber, preserving raw material character. Enhances tack and cohesion.
SBR Bale Rubber (Oil Extended)
Oil-extended SBR bales contain mineral oil up to 50 phr, in rectangular block form for footwear soles. Permitted under HTS 4002.19.00 per chapter note 5(a)(iii) as primary form retaining rubber character. Improves processing fluidity.
