Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If starch- or dextrin-based with polyurethane
Dextrin adhesives classify in Chapter 35 even with polymer additives, prioritizing adhesive preparation over base polymer.
If copolymers with <95% polyurethane monomers
Copolymers not meeting 95% threshold fall to 'Other' under 3909.50 per subheading note (a)(4), based on predominant monomer.
If packaged for retail as finished glue tube
Retail-packed plastic tubes of glue ≤38.1cm x 45.7cm may classify as plastic articles under 3921 per US note.
