Product classification
HS code for Polystyrene sheets: 3920.30
Plastics, of polymers of styrene, plates, sheets, film, foil and strip (not self-adhesive), non-cellular and not reinforced, laminated, supported or similarly combined with other materials.
Classification of polystyrene sheets under HS 3920.30
Polystyrene sheets that are non-cellular and not reinforced or laminated are classified under HS code 392030. This classification is part of heading 3920, which covers plates, sheets, film, foil, and strip of plastics that are not cellular and not combined with other materials. The sub-heading 392030 is specific to polymers of styrene. These products are typically solid, rigid, or flexible plastic layers produced through extrusion or calendering. To fall under this code, the sheets must not have a foam (cellular) structure and must not be self-adhesive. They are widely used in the manufacturing of food packaging, refrigerator liners, and various consumer goods. The classification is strictly based on the absence of internal air cells and the fact that the sheet is made of a single layer of polystyrene without backing or reinforcement from other materials like textiles or metal.

Codes often confused with 3920.30
Common mistake. The most frequent misclassification for this product is HS code 392111, which is for cellular (foam) polystyrene sheets. If the sheet has any foam-like properties, it cannot stay in 3920. Another common error is HS code 3919, which covers self-adhesive plates and sheets. If the polystyrene sheet has an adhesive backing, it must be classified under 3919. Furthermore, if the sheet is reinforced with glass fibers or laminated with other plastics, it would be classified under 392190. Importers must ensure the product is "non-cellular and not reinforced" to correctly apply code 392030.
Top exporters and importers of HS 392030 (the code used for polystyrene sheets), 2025
In 2025, the largest exporter of HS 392030 (the code used for polystyrene sheets) in UN Comtrade data was Germany, with 16% of world exports; the largest importer in UN Comtrade data was France, with 9.4% 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).

Questions about polystyrene sheets
What is the HS code for Polystyrene sheets?
The HS code for Polystyrene sheets is 392030 (Plastics; of polymers of styrene, plates, sheets, film, foil and strip (not self-adhesive), non-cellular and not reinforced, laminated, supported or similarly combined with other materials). The HS code for non-cellular, non-reinforced polystyrene sheets is 392030.
How do I classify Polystyrene sheets for customs?
Polystyrene sheets is classified under HS code 392030 — Plastics; of polymers of styrene, plates, sheets, film, foil and strip (not self-adhesive), non-cellular and not reinforced, laminated, supported or similarly combined with other materials. This is a 6-digit subheading level code.
How do I distinguish between 392030 and 392111?
HS code 392030 is for solid, non-cellular sheets, while 392111 is for cellular (foam) sheets. If the material is lightweight and contains air bubbles (like foam), use 392111.
Which countries are the top exporters of polystyrene sheets (HS 392030)?
