Product classification
HS code for Blended rubber: 4002.80
Rubber, mixtures of natural and synthetic rubbers of heading no. 4001 and 4002, in primary forms or in plates, sheets or strip.
Classification of blended rubber under HS 4002.80
Blended rubber is classified under HS code 4002.80. This classification falls under Chapter 40, which covers rubber and articles thereof. Heading 4002 is dedicated to synthetic rubber and factice derived from oils, in primary forms or in plates, sheets, or strips. Subheading 4002.80 specifically addresses mixtures of any product of heading 4001 (natural rubber) with any product of heading 4002 (synthetic rubber). The classification is based on the physical state of the material—it must be in a primary form like blocks, crumbs, or powders, or in unworked plates and sheets. This code is used for masterbatches or blends created to combine the high tensile strength of natural rubber with the chemical resistance of synthetic polymers like SBR or EPDM. The classification follows GRI 1 and Note 5 to Chapter 40, which defines the scope of mixtures of natural and synthetic rubbers.
- Covers
- Natural rubber and SBR (Styrene-Butadiene) blends
- Mixtures of natural rubber with Polybutadiene (BR)
- Natural rubber and EPDM masterbatches
- Blended rubber sheets for industrial gaskets (unvulcanized)
- Crumb rubber mixtures of natural and synthetic origin
- Also under 4002.80
- Michelin tire compounds
- Goodyear rubber blends
- Continental AG rubber materials
- Bridgestone raw rubber mixes
Codes often confused with 4002.80
Common mistake. Blended rubber is often misclassified under 4001.29 if the synthetic content is overlooked, or under 4002.19 if the natural rubber content is ignored. However, 4002.80 is the specific mandatory code for these mixtures. Another common error is using 4005.10, which is for compounded rubber (rubber mixed with carbon black or silica). If the blend contains reinforcing fillers, it must be classified under 4005 rather than 4002.
Top exporters and importers of HS 400280 (the code used for blended rubber), 2025
In 2025, the largest exporter of HS 400280 (the code used for blended rubber) in UN Comtrade data was Thailand, with 50% of world exports; the largest importer in UN Comtrade data was China, with 98% of world imports.

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).
