Import Tips
• Verify material composition via lab testing to confirm silicone polymer content exceeds 95% for proper Chapter 39 classification
• Include detailed technical specs and end-use certification in documentation to avoid misclassification as engine parts under Chapter 84
• Check for REACH compliance if sourced from EU; common pitfall is undervaluation on high-volume automotive shipments
