Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If primarily polyurethane in composition
If polyurethane monomer units predominate, it shifts to 3909.40 per predominance rule in subheading note (b)(1).
If as chemically modified polystyrene copolymer
Chemically modified copolymers not meeting amino-resin criteria fall to 'Other' in polystyrene series if styrene predominates.
