Import Tips
• Verify supplier certifications confirming TSNR Grade 10 specs (e.g
• <0.20% ash, <0.60% nitrogen) to avoid reclassification as compounded rubber
• Provide mill test reports and bale markings during customs entry to prove primary form status and prevent duty upgrades
• Watch for contamination with vulcanizing agents or fillers, which could shift classification out of heading 4001 per chapter notes
