Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If compounded with vulcanizing agents
Addition of vulcanizing agents excludes from 4002 per Note 5(a), moving to compounded rubber heading.
If for emulsion-polymerized versions
Solution polymerization specifies this subheading; emulsion SBR falls under different 4002.19 categories.
If supplied as prepared rubber latex
Latex/dispersion forms classify under 4004 or chemical preparations if not primary granules.

Import Tips & Compliance
• Include lab test results showing powder form and no prohibited compounding agents like pigments beyond identification use
• Check for REACH/SVHC compliance if from EU; US CBP requires proof of primary rubber character
• Avoid misdeclaration as finished adhesive (3506) by documenting raw material end-use
