Import Tips
• Verify purity certificate to confirm it's a separate chemically defined compound, not a mixture exceeding Chapter 29 scope
• Include Safety Data Sheets (SDS) documenting flame retardant use to avoid reclassification as plastic additive (Chapter 38)
• Check for halogenated impurities; if present in significant amounts, may shift to different subheading
