HS Code for Unvulcanized rubber sheets

HS code 4005.91 applies to unvulcanized compounded rubber presented in the form of plates, sheets, or strips. This classification is part of Chapter 40, which governs rubber products. Heading 4005 is specifically for compounded rubber that has not been vulcanized. The subheading 4005.91 is distinguished from other subheadings by two main factors: the physical shape (plates, sheets, or strips) and the absence of carbon black or silica. If the sheets contained carbon black or silica, they would be classified under 4005.10 regardless of their shape. These sheets are often used as raw materials for die-cutting or further molding into finished rubber parts. The material must be "compounded," meaning it contains additives like sulfur, pigments, or fillers, but it must remain in an unvulcanized state to qualify for this code. The thickness and width of the sheets can vary, but they must maintain a consistent geometric form to be excluded from the "primary forms" category.

Products Included

• Unvulcanized rubber plates (non-carbon black)
• Compounded rubber sheets for industrial gaskets
• Unvulcanized rubber strips in rolls
• Compounded rubber film (unvulcanized)
• Laminated unvulcanized rubber sheets

Common Misclassification

The most frequent error is confusing this code with 4008.11 or 4008.21, which cover vulcanized rubber plates and sheets. If the rubber has undergone the vulcanization process, it is no longer eligible for heading 4005. Additionally, if the unvulcanized sheet contains carbon black or silica, it must be classified under 4005.10, as that subheading takes precedence over 4005.91.

FAQ

What is the HS code for Unvulcanized rubber sheets?

The HS code for unvulcanized rubber sheets, plates, and strips (without carbon black or silica) is 4005.91.

Does this code include adhesive-backed rubber?

If the rubber is unvulcanized and compounded, it may fall here, but if it is primarily an adhesive product, it might be classified under 3506.
