Elastomeric Polyurethane Resin for Industrial Coatings
This is a primary form elastomeric polyurethane polymer used as a base resin for formulating durable industrial coatings and sealants. It meets the subheading criteria as a polyurethane where the monomer units contribute over 95% by weight, specifically designed for elastomeric properties providing flexibility and abrasion resistance. Classified under 3909.50.10.00 as elastomeric polyurethanes in primary forms.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If non-elastomeric polyurethane
Non-elastomeric polyurethanes fall under the 'Other' subheading in the series, as elastomeric specifically denotes rubber-like properties.
If copolymer with predominant non-polyurethane monomer
Per subheading note (a)(4), if another comonomer predominates by weight over polyurethane units, it classifies under the heading for that monomer's polymers.
If processed into synthetic rubber form
Elastomeric polymers vulcanized or otherwise hardened for rubber use move from Chapter 39 plastics to Chapter 40 rubbers.

Import Tips & Compliance
• Verify polymer composition via lab testing to confirm 95%+ polyurethane monomer content per subheading note (a)(1) to avoid reclassification to 'Other'
• Provide manufacturer's specification sheets documenting elastomeric properties and primary form (non-compounded) for CBP review
