Import Tips
• Verify vulcanization status and noncellular structure via lab testing to confirm Chapter 40 classification, avoiding textile exclusions
• Provide mill test certificates showing no hard rubber or cellular content; common pitfall is misclassifying as foam under 4008.11
• Ensure rectangular shape without further shaping to stay in 4008; document as 'uncut sheets' for customs
