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

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If containing more than 50 percent styrene by weight
Higher styrene content shifts classification within the same SBR subheading for different polymer composition.
If emulsion polymerized (E-SBR) rather than solution
Polymerization method determines specific subheading; emulsion SBR falls under butadiene 'other' synthetic rubbers.
If compounded with vulcanizing agents, fillers, or plasticizers
Compounded rubber mixtures lose primary form status and classify as compounded in Chapter 40 heading 4005.

Import Tips & Compliance
• 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
