Import Tips
• Verify monomer composition via lab analysis to confirm aromatic content exceeds predominant threshold per subheading note (a)(4)
• Ensure certificate of analysis specifies primary pellet or granular form, avoiding classification as compounded plastics in 3920
• Declare exact petroleum derivation to prevent misclassification under generic polymers
