Import Tips
• Request pre-shipment CBP classification binding ruling with full chemical structure and NMR analysis
• Ensure bill of lading describes as 'primary polymer forms, not articles' explicitly
• Pitfall: heat history documentation needed to prove non-chemically modified status per note (a)(3)
