Product classification
HS code for Compounded rubber: 4005.99
Rubber, unvulcanised, (compounded other than with carbon black or silica), in primary forms, (other than plates, sheets, strip, solutions or dispersions).
Classification of compounded rubber under HS 4005.99
Compounded rubber in primary forms is classified under HS code 4005.99. This classification is part of Chapter 40, which governs rubber and articles thereof. Heading 4005 specifically covers unvulcanised compounded rubber. To fall under 4005.99, the rubber must be mixed with substances such as fillers, plasticizers, or vulcanizing agents before vulcanization. This specific sub-heading is used for compounded rubber that is not mixed with carbon black or silica (which would fall under 4005.10) and is not in the form of plates, sheets, or strips (which would fall under 4005.91). It represents the material in its bulk primary form, such as blocks, lumps, or granules, ready for further processing into finished rubber goods.

Codes often confused with 4005.99
Common mistake. The most common misclassification is with HS code 4002, which covers synthetic rubber in primary forms. However, 4002 is only for rubber that has not been compounded with any ingredients necessary for vulcanization or other additives. Once fillers or vulcanizing agents are added, the product must move to 4005. Another error involves 4005.10; if the rubber contains any amount of carbon black or silica as a reinforcing agent, it must be classified under 4005.10 rather than 4005.99.

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).
