Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If vinyl chloride-styrene copolymer
Named copolymers like PVC-styrene with >95% units classify under 3904.10 per note (a)(2).
If polymer dissolved in solvent rather than primary solid form
Solvent-dissolved polymers may classify under Chapter 27 if meeting petroleum derivative criteria.
If fabricated into small plastic articles not elsewhere specified
Finished small wares from styrene polymers go to 3926.90, not primary forms.
