Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If reclaimed or waste-derived
Reclaimed rubber in 4003; primary synthetic rubber excludes reclaimed per Chapter structure.
If compounded with vulcanizing agents
Note 5(a) shifts compounded rubber from 4002 to 4005 (compounded with carbon black) or similar.
If chemically modified beyond vulcanizable synthetic rubber definition
Plastics chapter if no longer meets Note 2 vulcanization/elongation test for synthetic rubber.

Import Tips & Compliance
• Document coagulation process to prove primary form (crumbs permitted under Note 3(b)); avoid bulk forms mistaken for scrap
• Label with Mooney viscosity and CR grade for classification verification
