HS Code for Ebonite

Ebonite, also known as hard rubber, is classified under HS code 4017.00. This code encompasses hard rubber in all its forms, including bulk shapes like blocks, plates, sheets, rods, and tubes, as well as finished articles made of hard rubber and scrap material. Ebonite is distinguished from standard vulcanized rubber by its high sulfur content, typically ranging from 25% to 50%, which renders it rigid, brittle, and highly resistant to chemical corrosion and electrical conductivity. The classification applies regardless of whether the material is in its primary form or has been manufactured into a specific product, provided the material remains hard rubber. Because ebonite has unique physical properties compared to soft vulcanized rubber, the Harmonized System provides this dedicated heading to separate it from the more flexible rubber products found in headings 4001 through 4016.

Products Included

• Ebonite blocks and plates
• Hard rubber rods and tubes
• Ebonite waste and scrap
• Hard rubber battery cases
• Ebonite handles for tools
• Hard rubber combs and hair-slides

Common Misclassification

Ebonite is often misclassified under heading 3926, which covers articles of plastics, due to its rigid nature. However, because it is a vulcanized rubber product, it must remain in Chapter 40. It is also sometimes confused with standard vulcanized rubber under 4016; the distinction is the hardness and sulfur content. If the rubber is flexible, it cannot be classified under 4017.00. Additionally, synthetic rubber in its primary form is classified under 4002.

FAQ

What is the HS code for Ebonite?

The HS code for ebonite (hard rubber) in all forms, including articles and scrap, is 4017.00. This is a comprehensive code for the material and its finished products.

Is hard rubber classified the same as plastic?

No, hard rubber is classified under Chapter 40 (Rubber), specifically 4017.00, while plastics are classified under Chapter 39. The chemical composition, specifically the vulcanization with high sulfur content, dictates its classification as rubber.
