Solution Polymerized Styrene-Butadiene Rubber (S-SBR) in Bales from China

S-SBR produced via solution polymerization with 50% or less styrene content, compressed into bales for handling and storage. This synthetic rubber in primary bale form falls under HTS 4002.19.00.16 as it meets the definition of synthetic rubber in primary forms, not compounded with vulcanizing agents or fillers beyond permitted additives.

Import Tips

Verify styrene content ≤50% by dry weight via lab testing; provide certificates to customs for accurate classification

Confirm production method is solution polymerization (not emulsion) and product is in uncompounded bales without prohibited additives like vulcanizing agents

Include manufacturer specs showing compliance with synthetic rubber vulcanization/elongation tests per Chapter 40 note 2
