Import Tips & Compliance
• Bulk shipments require TSCA Pre-manufacture Notice if new use; check PMN status for your application
• Avoid stabilizer declarations that could reclassify under 3824; pure technical grade stays in 2903
• Monitor EU REACH compliance for origin certificates if sourced from Europe
