Metallized PET Window Insulation Film
Thin metallized polyethylene terephthalate (PET) film used for insulating windows to reduce heat loss and block UV rays. It meets HTS 3920.62.0050 as noncellular, unsupported metallized PET film, classified under poly(ethylene terephthalate) per subheading rules where PET monomers exceed 95% by weight. Primarily imported in rolls for residential DIY application.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If acrylic-modified PET exceeds specific thresholds
Chemically modified polymers not covered specifically fall under 'Other' per subheading note (a)(3), shifting from pure PET subheading.
If cut to precise shapes with adhesive backing for retail sale
Processed into flexible noncellular sheets with added features like adhesive becomes 'other forms' under 3921, not basic film of 3920.
If predominant monomer is not PET (e.g., PET/PE copolymer <95% PET)
Subheading note (a)(4) classifies copolymers by predominant monomer; if PET <95% and another prevails, moves to other polyester or plastic subheadings.

Import Tips & Compliance
• 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
