Import Tips

• Verify PET monomer content exceeds 95% by weight via lab testing to confirm classification under 3920.62 per subheading note (a)(1)

• Declare metallization as a thin vacuum-deposited layer (not laminated support) to avoid reclassification to 3920.63 or 3921

• Provide supplier specs on thickness (<0.10mm typical) and non-reinforced status; common pitfall is mislabeling as 'foil' triggering aluminum duties
