About heading 3902
Polymers of propylene or of other olefins, in primary forms
Heading 3902 covers polymers of propylene and other olefins in primary forms, such as pellets, granules, powders and blocks of resin. It is split by polymer type: polypropylene, polyisobutylene, propylene copolymers, and a residual other line that includes polybutylene. Primary forms means raw resin, not finished plastic articles.
