Subheadings
Products classified under HTS 4002.19.00
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.
High Vinyl SBR Solution
High-vinyl content SBR in organic solvent solution, for specialized sealants and modifiers. HTS 4002.19.00 includes such solutions as primary forms if vulcanizable per note 2(a), without compounding prohibitions. Offers better low-temperature flexibility.
SBR Masterbatch Pellets
SBR pellets pre-mixed with minimal stabilizers in primary pellet form for extrusion. Classifies under HTS 4002.19.00 as uncompounded synthetic rubber granules per chapter definitions. Facilitates uniform processing.
XSBR for Paper Coating Latex
Specialty XSBR latex formulated for paper and board coatings, providing water resistance. HTS 4002.19.00 as primary dispersion without disallowed pigments or fillers. Meets chapter's raw material criteria.
SBR Block Copolymer Sheets
Thin SBR sheets in rectangular form from block copolymerization, for rubber goods calendering. HTS 4002.19.00 per note 8 for simply cut sheets retaining primary character. Thermoplastic-like but vulcanizable.
