Polyacetals, other polyethers and epoxide resins, in primary forms; polycarbonates, alkyd resins, polyallyl esters and other polyesters, in primary forms
In plain English
This category covers various plastics in their basic forms, including polyacetals, polyethers, epoxide resins, polycarbonates, alkyd resins, and polyesters. The specific types are distinguished by their chemical structure, such as separating polyethers from polyacetals or identifying epoxide resins and polycarbonates as distinct groups. Polyesters are further divided based on their composition, with poly(ethylene terephthalate) classified by viscosity levels and poly(lactic acid) listed separately. Remaining polyesters are categorized as either unsaturated or saturated.

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.
