HS Code 3920.63 – Plastics; plates, sheets, film, foil and strip (not self-adhesive), of unsaturated polyesters, non-cellular and not reinforced, laminated, supported or similarly combined with other materials

HS code 3920.63 is the 6-digit subheading for plastics, plates, sheets, film, foil and strip (not self-adhesive), of unsaturated polyesters, non-cellular and not reinforced, laminated, supported or similarly combined with other materials. It is used for unsaturated polyester sheets, FRP prepreg films (unreinforced), electrical insulation sheets (UP), GRP base sheets (unreinforced) and chemical resistant UP sheets.

What HS 3920.63 covers

This HS code refers to non-cellular, non-reinforced plates, sheets, film, foil, and strip made from unsaturated polyesters, which are not self-adhesive or combined with other materials. Unlike PET, which is a thermoplastic, unsaturated polyesters are typically thermosetting resins, meaning they cure irreversibly to form rigid, durable materials. In sheet form, they are often used as precursors for fiberglass reinforced plastics (FRP) or in applications requiring high rigidity, chemical resistance, and heat stability, such as electrical insulation, construction panels, or specialized industrial components. Importers are typically manufacturers of composites, electrical equipment, or building materials. Exporters are specialized chemical companies producing these resins and their converted forms. Trade often involves specific resin formulations and curing characteristics.

Codes often confused with 3920.63

Common mistake. This is distinct from other polyesters like PET (392062) or other polyesters (392069) due to its 'unsaturated' nature and thermosetting properties. It could be confused with reinforced plastics (3921) if it contains reinforcing fibers.

How these figures are built

109 countries reported 2025 trade to UN Comtrade in HS 2022, and their own totals are used. Countries that did not report are estimated from what other countries recorded trading with them. Those estimates miss trade with other non-reporting countries, so they can be low, and a non-reporting country can rank higher than shown or be missing from the list. World totals add both and leave out trade between two non-reporting countries. Figures are in current US dollars; reported imports are mostly valued CIF and exports FOB, and exports include re-exports. The UN Comtrade links show the underlying records; they can also list a few reporters left out here (regional groups and older HS editions).

What products fall under HS code 392063?

Unsaturated polyester sheets, FRP prepreg films (unreinforced), Electrical insulation sheets (UP), GRP base sheets (unreinforced), Chemical resistant UP sheets, Thermoset polyester film.

What are common misclassifications for HS code 392063?

This is distinct from other polyesters like PET (392062) or other polyesters (392069) due to its 'unsaturated' nature and thermosetting properties. It could be confused with reinforced plastics (3921) if it contains reinforcing fibers.

Which countries are the top exporters of goods under HS code 392063?

In 2025, the top exporters of HS code 392063 in UN Comtrade data were China ($101M, 35% of world exports), Spain ($56M) and Italy ($28M).
