HS Code 4003.00 – Rubber; reclaimed rubber, in primary forms or in plates, sheets or strip
HS code 4003.00 is the 6-digit subheading for rubber, reclaimed rubber, in primary forms or in plates, sheets or strip. It is used for reclaimed tire rubber, butyl reclaim, EPDM reclaim, natural rubber reclaim and synthetic rubber reclaim sheets.
What HS 4003.00 covers
This HS code covers reclaimed rubber, which is essentially recycled rubber material, processed into primary forms like sheets, strips, or granules. Reclaimed rubber is a crucial component in the circular economy of the rubber industry, offering a sustainable alternative to virgin rubber and often at a lower cost. It's primarily used as a filler or extender in rubber compounds, improving processability and reducing material costs, particularly in applications where extreme performance isn't paramount. Major importers are typically countries with large-scale rubber manufacturing sectors looking to optimize costs and enhance sustainability, such as China, India, and various Southeast Asian nations. Exporters are often countries with significant waste rubber generation and recycling infrastructure, including the USA, European countries, and Japan. Key things to know involve the quality and consistency of the reclaimed material, as its properties can vary depending on the source and reclamation process, impacting its suitability for different applications like tire manufacturing, mats, or general rubber goods.

Codes often confused with 4003.00
Common mistake. This code can be confused with 400400 (rubber waste, parings, and scrap) if the material has not undergone the reclamation process to become a usable primary form, or with virgin rubber if its recycled nature is not declared.

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).
