Import Tips
• Verify monomer composition via certificate of analysis showing styrene-acrylonitrile units comprising ≥95% by weight to qualify under this specific subheading
• Ensure proper SDS (Safety Data Sheets) accompany shipments as these are hazardous materials under DOT regulations
• Avoid misclassification as general polystyrene (3903.11) by confirming copolymer content exceeds simple homopolymer specifications
