Code 3901 90 · Heading 3901

Other unprocessed ethylene polymers, excluding polyethylene and ethylene-vinyl acetate copolymers

This code covers ethylene polymers in unprocessed form that are not polyethylene or ethylene-vinyl acetate copolymers. The more specific child codes identify certain ionomer resins and A-B-A block copolymers separately.

For example

An unprocessed ethylene-alpha-olefin copolymer with density < 0.94
An unprocessed ionomer resin consisting of a salt of an ethylene terpolymer with isobutyl acrylate and methacrylic acid
