Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If polyester-polyisobutylene block copolymer
Block copolymers with polyester segments classify under polysiloxanes/polycarbonates per notes.
If extruded into finished profiles
Extruded plastic articles shift from primary polymers to Chapter 39 finished goods.
If for medical instrument components
Finished medical device parts classify under Chapter 90, not raw polymers.
