Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If classified as general synthetic rather than specific BR
Importers sometimes use broader 4002.10 for latex forms, but BR specificity governs.
If tubes or hoses made from it
Finished BR articles like tubes classify in 4009, not raw primary forms.
If conveyor belting material
BR belting or transmission belts fall under 4010 per note 7 inclusion.
