Product classification
HS code for Unsaturated polyester sheets: 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.
Classification of unsaturated polyester sheets under HS 3920.63
Unsaturated polyester sheets are classified under HS code 3920.63. This classification is governed by the physical form of the plastic and the specific polymer type. Heading 3920 covers plates, sheets, film, foil, and strip of plastics that are non-cellular and have not been reinforced, laminated, supported, or similarly combined with other materials. The subheading 3920.63 specifically identifies these products when they are made from unsaturated polyesters. These sheets are typically produced through casting or extrusion and are considered semi-finished products. To fall under this code, the sheets must not be self-adhesive (which would move them to 3919) and must not have been worked beyond surface treatments like printing, embossing, or simple cutting into rectangular shapes. The classification is strictly for 'simple' sheets; if the unsaturated polyester is reinforced with glass fibers (FRP), it is excluded from 3920 and must be classified under heading 3921, which covers other plates and sheets of plastics.

Codes often confused with 3920.63
Common mistake. A frequent error is classifying reinforced polyester sheets under 3920.63. If the sheet contains fiberglass or other reinforcing agents, it must be classified under 3921.90. Another common misclassification involves self-adhesive polyester films, which belong under HS code 3919.10 (in rolls) or 3919.90 (in sheets). Finally, sheets made of saturated polyesters (like PET) are classified under 3920.62, not 3920.63.
Top exporters and importers of HS 392063 (the code used for unsaturated polyester sheets), 2025
In 2025, the largest exporter of HS 392063 (the code used for unsaturated polyester sheets) in UN Comtrade data was China, with 35% of world exports; the largest importer in UN Comtrade data was Nigeria, with 9.9% of world imports. Countries that did not report 2025 data are estimated from partner records, which can understate them.

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).
