Polymers of propylene or of other olefins, in primary forms
In plain English
This category includes various polymers made from propylene or other olefins that are in their primary forms. The specific types are separated into groups based on their chemical structure, such as polypropylene, polyisobutylene, and propylene copolymers. Any other polymers of propylene or other olefins that do not fit into these specific categories are placed in a remaining group.

Chapter 39 classification notes
Frequent misclassification in this chapter
Composite articles (e.g., plastic with textile lining) — classify by the material giving essential character. Silicone products are often misclassified here but belong in Chapter 39.
Classification certainty
The 6-digit level shown here is the internationally harmonised layer. Duty rates attach to national 8-10 digit tariff lines, which differ by country — use the duty calculator for lane estimates. For binding certainty, request a ruling from the destination customs authority.
