Grade 3 Smoked Rubber Sheets from Canada
These are natural rubber sheets produced from latex coagulated into sheets, then smoked over wood fires to preserve and darken them, specifically meeting Grade 3 quality standards with moderate impurities and discoloration. Classified under HTS 4001.21.00.30 as smoked sheets of natural rubber in primary forms, they serve as a raw material for further processing into tires, seals, and footwear. The smoking process imparts elasticity and durability typical of natural rubber.
