HS Code 3921.12 – Plastics; plates, sheets, film, foil and strip, of polymers of vinyl chloride, cellular
HS code 3921.12 is the 6-digit subheading for plastics, plates, sheets, film, foil and strip, of polymers of vinyl chloride, cellular. It is used for foamed PVC sheets, cellular PVC panels, PVC foam boards for signage, marine-grade PVC foam and lightweight construction panels.
What HS 3921.12 covers
This code covers cellular plastics made from polymers of vinyl chloride, primarily cellular PVC (foamed PVC), in the form of plates, sheets, film, foil, and strip. These materials are traded for their unique combination of lightweight structure, rigidity, chemical resistance, and inherent flame retardancy. Cellular PVC is widely used in construction, signage, and marine applications where durability and resistance to moisture and chemicals are critical. International trade involves manufacturers seeking alternatives to traditional materials like wood or metal, particularly for outdoor or corrosive environments. Importers are typically fabricators of building materials, advertising displays, and boat components. Exporters are specialized PVC compounders and foam sheet manufacturers. The market is driven by demand for low-maintenance, weather-resistant materials in construction and advertising sectors.

Codes often confused with 3921.12
Common mistake. Can be confused with 392111 (cellular polystyrene) or 392113 (cellular polyurethanes) if the specific polymer is not identified, or 392043 (non-cellular PVC) if the cellular nature is overlooked.
Top exporters and importers of HS code 392112, 2025
In 2025, the largest exporter of HS code 392112 in UN Comtrade data was China, with 37% of world exports; the largest importer in UN Comtrade data was Mexico, with 25% of world imports. Vietnam did not report 2025 data, and its estimate from partner records misses its trade with other countries that did not report: in 2024 that was 2.4% of its imports here ($2.2M, CEPII BACI), so it may also belong among the top importers.

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).
