Alternative Classifications

This product could be classified differently depending on its characteristics or intended use.

3909.31.00.00Higher: 41.5% vs 35%

If marketed as a finished thermosetting polyurethane resin for industrial molding

Polyurethanes in primary forms from diisocyanates fall under Chapter 39 polymers, not NES preparations.

3824.99Same rate: 35%

If aromatic content <5% by weight

Fails the specific threshold for 3824.99.26, moving to general 'other' chemical mixtures.

3208.10.00.00Higher: 38.7% vs 35%

If formulated and sold as a paint or varnish base

Polyisocyanate prepolymers used in coatings are classified under paints/varnishes rather than chemical preparations.
