HS Code for Compounded rubber

Compounded rubber in primary forms is classified under HS code 4005.99. This classification is part of Chapter 40, which governs rubber and articles thereof. Heading 4005 specifically covers unvulcanised compounded rubber. To fall under 4005.99, the rubber must be mixed with substances such as fillers, plasticizers, or vulcanizing agents before vulcanization. This specific sub-heading is used for compounded rubber that is not mixed with carbon black or silica (which would fall under 4005.10) and is not in the form of plates, sheets, or strips (which would fall under 4005.91). It represents the material in its bulk primary form, such as blocks, lumps, or granules, ready for further processing into finished rubber goods.

Products Included

• Unvulcanised rubber masterbatches without carbon black or silica
• Compounded natural rubber in bulk blocks
• Compounded synthetic rubber granules
• Rubber mixtures containing plasticizers or antioxidants
• Unvulcanised rubber paste for industrial molding

Common Misclassification

The most common misclassification is with HS code 4002, which covers synthetic rubber in primary forms. However, 4002 is only for rubber that has not been compounded with any ingredients necessary for vulcanization or other additives. Once fillers or vulcanizing agents are added, the product must move to 4005. Another error involves 4005.10; if the rubber contains any amount of carbon black or silica as a reinforcing agent, it must be classified under 4005.10 rather than 4005.99.

FAQ

What is the HS code for compounded rubber?

The HS code for unvulcanised compounded rubber in primary forms (excluding plates/sheets and carbon black mixtures) is 4005.99.

Can vulcanized rubber be classified here?

No, heading 4005 is strictly for unvulcanised rubber. Vulcanized rubber is classified under headings 4007 through 4017 depending on the form and product.
