Product classification
HS code for Carbon black rubber compound: 4005.10
Rubber, unvulcanised, compounded with carbon black or silica, in primary forms or in plates, sheets or strip.
Classification of carbon black rubber compound under HS 4005.10
Carbon black rubber compound is classified under HS code 4005.10. This classification is based on the product being unvulcanised rubber that has been mixed or 'compounded' with specific reinforcing agents. Chapter 40 covers rubber and articles thereof, and heading 4005 is dedicated to compounded rubber, unvulcanised, in primary forms or in plates, sheets, or strip. Subheading 4005.10 specifically identifies rubber compounded with carbon black or silica. Carbon black is added to raw rubber to improve its mechanical properties, such as tensile strength and abrasion resistance, making it a critical intermediate product for the automotive and industrial sectors. To qualify for this code, the material must remain in an unvulcanised state; once it is vulcanized, it is classified elsewhere in Chapter 40 depending on its final form.

Codes often confused with 4005.10
Common mistake. This product is often misclassified under HS code 2803.00, which is the code for pure carbon black. However, once the carbon black is mixed with rubber, it must be classified in Chapter 40. Another common error is using 4002, which covers synthetic rubber; however, 4002 is for rubber that has not yet been compounded with fillers like carbon black. Finally, if the rubber is already vulcanized, it should be classified under 4008 (plates/sheets) or 4016 (other articles).

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).
