Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If compounded with vulcanizing agents or fillers
Compounded synthetic rubber mixtures lose primary form status per Chapter note 5(a) and shift to heading 4005.
If not meeting strict BR vulcanization test
Other synthetic rubbers not qualifying as BR under note 1(c) fall into the residual 4002.99 category.
If polymerized without rubber elasticity properties
Non-rubber synthetic polymers like certain styrene copolymers classify in Chapter 39, plastics.

Import Tips & Compliance
• Verify no vulcanizing agents, pigments, or fillers beyond permitted additives to retain primary form classification
• Provide certificate of analysis confirming BR content and compliance with Chapter 40 note 5 on synthetic rubber definition
• Avoid misclassification as compounded rubber (4005) by ensuring essential raw material character
