About HS Code 392063

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.

Products Under This Code

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

Real World Examples

Ashland unsaturated polyester resins, Reichhold UPR, Polynt UPR, AOC Resins UPR.

Common Misclassification

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.
