Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If flexible SAN tubing
Flexible counterparts in 3917.31 for other plastics.
If reservoirs or doors for conveyance
Plastic reservoirs/tanks shift if storage primary over pipe flow.
If imported as polymer, not pipe
Polystyrene copolymers unworked under 3903; fabrication state matters.
