SBR Crumb Rubber (Hot Polymerized) from China
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.

Import Tips
• Certify polymerization method (hot vs cold) and Mooney viscosity; ensure crumbs retain vulcanizable character without pigments
• Use ventilated containers to prevent agglomeration; differentiate from reclaimed rubber
