Rubber, reclaimed rubber, in primary forms or in plates, sheets or strip.
Classification of reclaimed rubber under HS 4003.00
Reclaimed rubber is classified under HS code 400300. This classification applies to rubber that has been recovered from used tires or other waste rubber products through various mechanical or chemical processes, such as devulcanization. The resulting material must be presented in primary forms, such as blocks, or in plates, sheets, or strips. This code is specific to the material's status as a recycled product that has been processed back into a usable raw material state. The classification depends on the rubber being "reclaimed" rather than simply being scrap or waste that has not yet undergone a recovery process.

Codes often confused with 4003.00
Common mistake. A common error is classifying this material under HS code 400400, which is reserved for waste, parings, and scrap of rubber (other than hard rubber) and powders or granules obtained therefrom. The distinction is that 400300 covers rubber that has been processed into a primary form for reuse, whereas 400400 is for raw waste. Additionally, virgin natural rubber (4001) or virgin synthetic rubber (4002) should not be confused with reclaimed rubber, as the latter is derived from previously vulcanized products.

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).
