Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If prepared as ready-to-use adhesive
Finished adhesives, even polyurethane-based, classify under prepared glues rather than primary polymers.
If non-elastomeric hot-melt polyurethane
Rigid polyurethanes without rubber-like properties go to 'Other' subheading.
If polyester-polyol based with different dominant monomer
Classification follows predominant monomer if polyurethane units don't meet 95% threshold per notes.

Import Tips & Compliance
• Distinguish primary resin from formulated adhesives (3929+); only uncompounded polymers qualify for 3909 classification
• Provide FTIR or NMR spectra confirming polyurethane structure and elastomeric properties during entry
