Product classification
HS code for Compounded rubber sheets: 4005.91
Rubber, unvulcanised, (compounded other than with carbon black or silica), in plates, sheets and strip.
Classification of compounded rubber sheets under HS 4005.91
Compounded rubber sheets are classified under HS code 4005.91. This code is designated for unvulcanised rubber that has been compounded with additives (such as sulfur, accelerators, or plasticizers) and processed into specific geometric shapes like plates, sheets, or strips. The classification is driven by the physical form of the material and its unvulcanised state. Under the General Rules for the Interpretation of the Harmonized System, the specific shape (sheet) takes precedence over the general primary form (bulk) when the product has been rolled or extruded into a flat profile. These sheets are typically intermediate products used in the manufacture of tires, gaskets, or shoe soles, requiring heat and pressure to achieve their final vulcanized state.

Codes often confused with 4005.91
Common mistake. Compounded rubber sheets are often misclassified under HS code 4008, which covers plates, sheets, and strips of vulcanized rubber. The critical distinction is the state of vulcanization; 4005.91 is only for unvulcanised material. If the rubber has undergone the curing process, it must move to 4008. Additionally, if the sheet is made of pure natural rubber without any compounding ingredients, it would fall under 4001, while pure synthetic rubber sheets without additives fall under 4002.

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).
