Product classification
HS code for IR rubber: 4002.60
Rubber, synthetic, isoprene rubber (IR), in primary forms or in plates, sheets or strip.
Classification of IR rubber under HS 4002.60
Isoprene rubber (IR) is classified under HS code 4002.60. This code specifically covers synthetic polyisoprene, which is a polymer produced through the polymerization of isoprene monomers in an industrial setting. Although IR is chemically similar to natural rubber (cis-1,4-polyisoprene), the Harmonized System distinguishes between products derived from biological sources and those produced synthetically. Heading 4002 is the designated category for synthetic rubber. The classification 4002.60 applies to IR in primary forms, such as blocks, lumps, or bales, as well as in unvulcanized plates, sheets, or strips. This classification is critical for trade monitoring, as IR is often used as a high-purity substitute for natural rubber in medical and high-performance industrial applications where consistency and lack of impurities are paramount.

Codes often confused with 4002.60
Common mistake. The most frequent misclassification for IR rubber is HS code 4001.22 (technically specified natural rubber) or 4001.10 (natural rubber latex). Because the chemical structures are nearly identical, laboratory testing may be required to confirm the synthetic origin. Another confusion arises with 4002.19, which covers other synthetic rubbers like SBR. It is vital to specify "Isoprene Rubber" on shipping documentation to ensure the 4002.60 code is applied correctly.
Top exporters and importers of HS 400260 (the code used for IR rubber), 2025
In 2025, the largest exporter of HS 400260 (the code used for IR rubber) in UN Comtrade data was Russia, with about 41% of world exports; the largest importer in UN Comtrade data was China, with 27% 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 marked * did not, so their figures add up what other countries recorded trading with them, and their exports are valued at buyers' CIF prices. 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).
