Import Tips
• Verify material composition via lab testing to confirm it's vulcanized rubber and not hard rubber, as hard rubber excludes from Chapter 40
• Provide detailed technical specs and end-use certification to avoid misclassification as machinery parts under Chapter 84
• Ensure FDA compliance if used in fuel systems contacting food-grade components to prevent regulatory delays
