Product classification
HS code for Solid rubber blocks: 4008.29
Rubber, vulcanised (other than hard rubber), non-cellular rubber, in forms other than plates, sheets or strip.
Classification of solid rubber blocks under HS 4008.29
Solid rubber blocks are classified under HS code 4008.29. This classification is governed by the rules of Chapter 40, which covers rubber and articles thereof. Heading 4008 specifically addresses plates, sheets, strip, rods, and profile shapes of vulcanised rubber other than hard rubber. The determination for 4008.29 is based on the physical form and the nature of the rubber. Since these blocks are made of non-cellular (solid) vulcanised rubber and do not meet the geometric definitions of plates, sheets, or strips (which are covered under 4008.21), they are categorized under the "other" subheading 4008.29. This code is intended for semi-manufactured forms that have been vulcanised but not yet converted into finished articles. The material must not be hard rubber (ebonite), which is classified elsewhere in the chapter. The classification relies on the fact that the product is a primary or semi-finished shape intended for further industrial processing or cutting into specific components.

Codes often confused with 4008.29
Common mistake. Solid rubber blocks are frequently confused with HS code 4008.21, which is reserved strictly for plates, sheets, and strips. If the block has a uniform thickness and a rectangular surface area that qualifies it as a sheet, it must move to 4008.21. Another common error is using HS code 4016.99, which covers other articles of vulcanised rubber. Code 4016 is for finished products, whereas 4008 is for semi-finished shapes. If the block has been further worked into a specific part, such as a bumper or a mount, it should be classified under 4016.

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).
