Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If processed into plates, sheets, or profile shapes
Extruded or cut-to-shape BR forms beyond primary bulk move to heading 4008 per note 8 definitions.
If waste parings from BR manufacturing
Scrap or unusable cuttings from rubber working classify as waste under heading 4004 per note 6.
If oil-extended beyond permitted levels
Excessive mineral oil extension may shift to petroleum oils if losing rubber character.

Import Tips & Compliance
• Ensure granules are simply cut from bales without surface working beyond Chapter note 8 allowances
• Include technical data sheet proving unsaturated BR eligible for sulfur vulcanization per Chapter note 1
• Watch for reclassification to 4008 if formed into rods or profiles exceeding thread dimensions
