HS code for Mixed 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 mixed rubber under HS 4002.80
Mixed rubber is classified under HS code 4002.80. This code is part of 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 strip. Subheading 4002.80 specifically addresses mixtures of any product of heading 4001 (natural rubber) with any product of heading 4002 (synthetic rubber). This classification is technical and depends on the chemical composition of the rubber blend. According to the Chapter 40 notes, synthetic rubber applies to unsaturated synthetic substances which can be irreversibly transformed by substances into non-thermoplastic substances. The 4002.80 code is used for masterbatches or blends where natural and synthetic elastomers are combined before the addition of fillers, vulcanizing agents, or other compounding ingredients. It is essential for manufacturers who produce intermediate rubber blends for the automotive, construction, or footwear industries.

Codes often confused with 4002.80
Common mistake. Mixed rubber is frequently confused with HS code 4005. Heading 4005 covers compounded rubber, unvulcanized, in primary forms or in plates, sheets, or strip. The distinction is that 4005 includes rubber mixed with carbon black, silica, or other reinforcing agents, as well as vulcanizing agents. If the mixture only contains the rubber polymers themselves (natural and synthetic), it stays in 4002.80. If additives are present, it moves to 4005.

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).
