HS Code for SBR rubber

Styrene-butadiene rubber (SBR) is classified under HS code 4002.19 because it is a synthetic rubber derived from the copolymerization of styrene and butadiene. This specific subheading is reserved for SBR and carboxylated styrene-butadiene rubber (XSBR) that is presented in primary forms, such as bales, blocks, or crumbs, or in plates, sheets, and strips. The classification is governed by the notes to Chapter 40, which define synthetic rubber based on its ability to be vulcanized and its elongation properties. HS code 4002.19 specifically excludes latex forms, which are categorized elsewhere. The determination of this code depends on the monomer content; for a product to be classified here, the styrene and butadiene must constitute the predominant weight of the synthetic rubber component. This material is widely used in the tire industry and for technical rubber goods due to its abrasion resistance and aging stability.

Products Included

• Non-latex SBR in blocks or bales
• Oil-extended styrene-butadiene rubber
• Carboxylated SBR (XSBR) in primary forms
• SBR sheets and strips for industrial manufacturing
• Unvulcanized SBR compounds in crumbs

Common Misclassification

SBR is frequently misclassified under HS code 4002.11, which is specifically for SBR in latex (liquid) form. Another common error is using 4001.10 or 4001.21, which are reserved for natural rubber. If the rubber has been reclaimed from used tires or tubes, it must be classified under 4003.00 rather than 4002.19. Furthermore, if the SBR is already vulcanized and cut to specific shapes for consumer use, it may fall under 4008 or 4016.

FAQ

What is the HS code for SBR rubber?

The HS code for SBR rubber in primary forms (excluding latex) is 4002.19.

What is the difference between 4002.11 and 4002.19?

HS code 4002.11 is strictly for styrene-butadiene rubber in the form of latex (aqueous dispersion), while 4002.19 covers solid primary forms like bales and sheets.
