Last updated: August 2026 dataPolypropylene (PP) resin in primary forms — pellets, granules, powder, or flake — is one of the most widely traded commodity plastics globally, serving as a feedstock for injection-molded parts, woven bags, nonwoven fabrics, and automotive components. The entire heading resolves to a single 10-digit line (3902100000), so classification disputes typically arise not from line selection but from distinguishing polypropylene homopolymer from propylene copolymers (heading 390230) based on comonomer content. Canada leads US imports, with South Korea and Germany also significant sources. Importers sourcing from South Korea may evaluate KORUS FTA eligibility for qualifying shipments.

The key is comonomer content: a homopolymer contains only propylene repeat units, while a copolymer incorporates a second monomer such as ethylene. Suppliers should provide a certificate of composition or polymer data sheet specifying the monomer ratio. Even small amounts of comonomer can shift classification to heading 390230, so lot-level documentation is advisable.
PP resin is typically shipped in bulk railcar, bulk container (flexi-bag or box), or 25 kg bags. Moisture ingress during transit can affect melt-flow index and surface quality of molded parts, so importers should specify desiccant requirements and verify container integrity. Port dwell time also matters because extended outdoor storage in humid climates can degrade certain additive packages.
