Polyurethane Resin for Coatings
A primary form polyurethane polymer used as a base resin in industrial coatings and paints. It falls under HTS 3909.50.5000 as 'Other' polyurethanes in primary forms, meeting the criteria where polyurethane monomer units contribute over 95% by weight. This classification applies to unmodified polyurethane resins not specified elsewhere in the series.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If polyurethane content below 95% and epoxy predominates
Copolymers where epoxy monomer units exceed polyurethane by weight classify under epoxy resins per subheading note (a)(4).
If chemically modified polyurethane
Chemically modified polymers without a specific subheading go to 'Other' in the series, but significant mods may fit polyacetals or other headings.
If processed into plates, sheets, or non-primary forms
Once converted beyond primary form (e.g., pellets to sheets), it moves from Chapter 39 polymers to Chapter 39 plates/sheets.

Import Tips & Compliance
• Verify monomer composition via lab analysis to confirm 95%+ polyurethane units for accurate classification under 3909.50.5000
• Provide certificates of analysis (COA) showing primary form and no chemical modification to avoid reclassification
