HS Code for Unvulcanized rubber compound
HS code 4005.99 is used for compounded rubber that has not yet undergone the vulcanization process. Chapter 40 of the Harmonized System covers rubber and articles thereof. Heading 4005 specifically addresses compounded rubber, unvulcanized, in primary forms or in plates, sheets, or strip. Subheading 4005.99 is a residual category for compounded rubber in primary forms (such as blocks, lumps, or powders) that do not contain carbon black or silica. If the rubber compound were mixed with these reinforcing agents, it would fall under 4005.10. Furthermore, this specific code excludes forms like plates, sheets, or strips, which are classified under 4005.91. The classification is determined by the chemical composition—specifically the presence of vulcanizing agents, accelerators, or plasticizers—and the physical form of the material. This material is typically an intermediate product intended for further processing into finished rubber goods through heat and pressure.
Products Included
- Unvulcanized rubber blocks without carbon black
- Compounded rubber granules for molding
- Unvulcanized rubber masterbatch (non-silica)

Common Misclassification
This code is often confused with HS code 4005.10, which is specifically for compounded rubber containing carbon black or silica. If either of those reinforcing agents is present, 4005.10 takes precedence. Additionally, it is often confused with 4002, which covers synthetic rubber that has not been compounded with vulcanizing agents or other additives. Once additives are mixed into the rubber, it must move from 4002 to 4005.
