Benzene 2,4-Diisocyanate-1,3,5-Tris(1-Methylethyl) Homopolymer Resin
This is a specialized aromatic homopolymer resin derived from benzene 2,4-diisocyanate-1,3,5-tris(1-methylethyl), used in high-performance coatings and adhesives. It falls under HTS 3824.99.26.00 because it is explicitly listed as a chemical preparation containing 5% or more by weight of this specific aromatic substance, classified as a mixture or preparation not elsewhere specified.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
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.
If aromatic content <5% by weight
Fails the specific threshold for 3824.99.26, moving to general 'other' chemical mixtures.
If formulated and sold as a paint or varnish base
Polyisocyanate prepolymers used in coatings are classified under paints/varnishes rather than chemical preparations.
