HS Code for Compounded rubber sheets

Compounded rubber sheets are classified under HS code 4005.91. This code is designated for unvulcanised rubber that has been compounded with additives (such as sulfur, accelerators, or plasticizers) and processed into specific geometric shapes like plates, sheets, or strips. The classification is driven by the physical form of the material and its unvulcanised state. Under the General Rules for the Interpretation of the Harmonized System, the specific shape (sheet) takes precedence over the general primary form (bulk) when the product has been rolled or extruded into a flat profile. These sheets are typically intermediate products used in the manufacture of tires, gaskets, or shoe soles, requiring heat and pressure to achieve their final vulcanized state.

Products Included

• Unvulcanised compounded rubber plates
• Compounded rubber strips for tire retreading
• Calendered unvulcanised rubber sheets
• Adhesive-backed unvulcanised rubber strips
• Compounded rubber flooring underlay in unvulcanised sheet form

Common Misclassification

Compounded rubber sheets are often misclassified under HS code 4008, which covers plates, sheets, and strips of vulcanized rubber. The critical distinction is the state of vulcanization; 4005.91 is only for unvulcanised material. If the rubber has undergone the curing process, it must move to 4008. Additionally, if the sheet is made of pure natural rubber without any compounding ingredients, it would fall under 4001, while pure synthetic rubber sheets without additives fall under 4002.

FAQ

What is the HS code for compounded rubber sheets?

The HS code for unvulcanised compounded rubber in plates, sheets, or strips is 4005.91.

Does this code include carbon black mixtures?

No, if the compounded rubber sheet contains carbon black or silica, it is generally classified under 4005.10, although some jurisdictions prioritize the 4005.91 form-based code.
