HS Code 4005.10 – Rubber; unvulcanised, compounded with carbon black or silica, in primary forms or in plates, sheets or strip
HS code 4005.10 is the 6-digit subheading for rubber, unvulcanised, compounded with carbon black or silica, in primary forms or in plates, sheets or strip. It is used for carbon black masterbatch, silica-filled rubber compounds, unvulcanized tire tread compounds, rubber sheeting with carbon black and pre-mixed rubber compounds.
What HS 4005.10 covers
This HS code covers unvulcanized rubber that has been compounded specifically with carbon black or silica, traded in primary forms like bales, sheets, or strips. This pre-compounded rubber is a critical intermediate product, offering manufacturers a ready-to-use material that only requires shaping and vulcanization. Carbon black and silica are essential reinforcing fillers, significantly enhancing the strength, durability, and abrasion resistance of the final rubber product, particularly in tires and industrial goods. Major importers are typically tire manufacturers and other rubber product fabricators in countries like China, the United States, and Germany, seeking consistent, high-quality raw materials. Exporters are often specialized rubber compounders or large chemical companies in nations with advanced processing capabilities, such as Japan, Germany, and the USA. Key things to know include the precise formulation, filler type and loading, and the base rubber polymer, as these dictate the performance characteristics and suitability for specific applications, streamlining the manufacturing process for downstream industries. This code is also subject to EUDR regulations.

Codes often confused with 4005.10
Common mistake. This code can be confused with 400591 or 400599 if the specific compounding agents (carbon black or silica) are not identified, or with vulcanized rubber (Chapter 40, later headings) if its unvulcanized state is overlooked.
Top exporters and importers of HS code 400510, 2025
In 2025, the largest exporter of HS code 400510 in UN Comtrade data was Germany, with 14% of world exports; the largest importer in UN Comtrade data was India, with 13% 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 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).
