Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If semi-flexible
Any flexibility moves to 3917.39 subheading for other plastics.
If household or kitchen use tableware-like pipes
Household plastic articles exclude pipes but fittings may go 3924 per note.
If misidentified as PVC
Only if vinyl chloride 95%+; polysulfone differs chemically.
