HS Code for Blended rubber

Blended rubber is classified under HS code 4002.80. This classification falls under Chapter 40, which covers rubber and articles thereof. Heading 4002 is dedicated to synthetic rubber and factice derived from oils, in primary forms or in plates, sheets, or strips. Subheading 4002.80 specifically addresses mixtures of any product of heading 4001 (natural rubber) with any product of heading 4002 (synthetic rubber). The classification is based on the physical state of the material—it must be in a primary form like blocks, crumbs, or powders, or in unworked plates and sheets. This code is used for masterbatches or blends created to combine the high tensile strength of natural rubber with the chemical resistance of synthetic polymers like SBR or EPDM. The classification follows GRI 1 and Note 5 to Chapter 40, which defines the scope of mixtures of natural and synthetic rubbers.

Products Included

• Natural rubber and SBR (Styrene-Butadiene) blends
• Mixtures of natural rubber with Polybutadiene (BR)
• Natural rubber and EPDM masterbatches
• Blended rubber sheets for industrial gaskets (unvulcanized)
• Crumb rubber mixtures of natural and synthetic origin

Common Misclassification

Blended rubber is often misclassified under 4001.29 if the synthetic content is overlooked, or under 4002.19 if the natural rubber content is ignored. However, 4002.80 is the specific mandatory code for these mixtures. Another common error is using 4005.10, which is for compounded rubber (rubber mixed with carbon black or silica). If the blend contains reinforcing fillers, it must be classified under 4005 rather than 4002.

FAQ

What is the HS code for blended rubber?

The HS code for mixtures of natural and synthetic rubber in primary forms is 4002.80.

Does the ratio of natural to synthetic rubber matter?

For classification under 4002.80, any mixture of products from 4001 and 4002 qualifies, regardless of the specific ratio, provided it is in a primary form and not compounded with fillers.
