Smoked Rubber Sheets Grade RSS3 from Mexico
Smoked rubber sheets (Ribbed Smoked Sheet Grade 3) are produced from natural latex coagulated into sheets, ribbed, air-dried, and smoked over wood fires to preserve and standardize quality. Classified under HTS 4001.21.0050 as 'other' smoked sheets in primary forms, these retain the essential character of raw natural rubber without vulcanizing agents or fillers beyond permitted additives.

Import Tips
• Verify no vulcanizing agents, pigments, or extenders beyond emulsifiers/antitack agents to maintain primary form classification per chapter note 5
• Obtain certificate of origin and quality specs (e.g
• dirt content <0.20%, ash <0.75%) for customs valuation and compliance
• Avoid misclassification as processed sheets if surface-worked beyond simple rectangular cuts
