HS Code for Polypropylene

Polypropylene copolymers are classified under HS code 3902.30. This code is part of the broader heading 3902, which encompasses polymers of propylene or other olefins in primary forms. The distinction for 3902.30 lies in the fact that the material is a copolymer rather than a homopolymer. In chemical terms, a copolymer is formed when two or more different types of monomers are polymerized together. For this specific HS code, propylene must be the predominant monomer by weight compared to any other single comonomer. These copolymers are often engineered to have specific physical properties, such as increased impact resistance, improved clarity, or lower melting points, which differ from standard polypropylene homopolymers (classified under 3902.10). The classification requires the product to be in a primary form, such as pellets, granules, or flakes, intended for further processing via injection molding, extrusion, or other plastic fabrication techniques. Accurate classification depends on laboratory analysis or technical data sheets confirming the copolymeric nature of the resin and the percentage of propylene content relative to other monomers like ethylene.

Products Included

• Propylene-ethylene copolymers
• Random copolymer polypropylene (PPR)
• Impact copolymer polypropylene
• Propylene-based plastomers
• Propylene-based elastomers in primary form

Common Misclassification

The most frequent misclassification is using HS code 3902.10, which is exclusively for polypropylene homopolymers. Importers often fail to distinguish between a pure polymer and a copolymer. Another error involves HS code 3901, which is for ethylene polymers; if ethylene is the predominant monomer by weight, the product must be moved to Chapter 3901, even if it contains propylene. Finally, chemically modified polypropylene may sometimes be incorrectly placed here instead of 3902.90.

FAQ

What is the HS code for polypropylene copolymers?

The HS code for propylene copolymers in primary forms is 3902.30.

How do I distinguish between 3902.10 and 3902.30?

Check the technical specifications; if the resin contains only propylene monomers, use 3902.10. If it contains propylene and another monomer (like ethylene) as a copolymer, use 3902.30.
