Solution Styrene Butadiene Rubber (SSBR)
Solution-polymerized styrene-butadiene rubber (SSBR) in crumb form, a synthetic rubber that is predominantly butadiene with a minor styrene content. The crumbs are uncompounded and retain the essential character of raw butadiene rubber for high-performance tires. It meets the vulcanization and recovery tests of Chapter 40 Note 4.

More Specific Codes
This product may fall under a more specific subheading:
Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If the styrene content is significant enough to make SBR the predominant rubber
Styrene-butadiene rubber is classified under heading 4002.19, not 4002.20.
If the crumbs are blended with other polymers or contain prohibited substances
Other synthetic rubber forms fall under residual heading 4002.99.

Import Tips & Compliance
• Confirm the styrene content is minor and the rubber is predominantly butadiene; if styrene is the major component, it may fall under SBR headings
• Provide documentation showing the crumbs are uncompounded and free of prohibited additives
• Verify the rubber meets the elongation/recovery criteria of Note 4
