Import Tips
• Verify the rubber is natural (not synthetic) via supplier certification or lab testing to confirm HTS 4016.99.35 classification
• Include material composition documentation; natural rubber content must exceed synthetic blends to avoid reclassification
• Check for Chapter 40 exclusions like mechanical parts (Section XVI); seals must not incorporate electrical components
