Rubber, vulcanised (other than hard rubber), in plates, sheets and strip, of non-cellular rubber.

Classification of solid rubber sheets under HS 4008.21

Solid rubber sheets are classified under HS code 4008.21. This code is part of the Harmonized System's Chapter 40, dedicated to rubber products. Heading 4008 is reserved for plates, sheets, strip, rods, and profile shapes made of vulcanised rubber, excluding hard rubber. The subheading 4008.21 specifically identifies non-cellular rubber that has been processed into flat forms such as plates, sheets, or strips. To qualify for this code, the rubber must be vulcanised, meaning it has undergone a chemical process to improve its elasticity and durability. Furthermore, the "non-cellular" designation ensures that the material is solid throughout and does not contain a foam or sponge-like structure. These sheets are typically used as raw materials for gaskets, seals, or industrial flooring. The classification applies to sheets that are either in rolls or cut into rectangular shapes but have not been further worked into a finished article.

Codes often confused with 4008.21

Common mistake. A common misclassification occurs with HS code 4008.11, which is used for cellular (foam or sponge) rubber sheets. If the rubber contains air cells, it must be classified under 4008.11. Additionally, importers often confuse these with plastic sheets under HS code 3921. The distinction depends entirely on whether the material meets the definition of rubber or plastic according to the Chapter 40 notes. Finally, if the sheet is cut to a specific non-rectangular shape, it may be classified as a finished article under 4016.

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).
