HS Code for Styrene-butadiene rubber latex

Styrene-butadiene rubber latex is classified under HS code 4002.11. This classification is part of the synthetic rubber category in Chapter 40 of the Harmonized System. The term "latex" refers to a stable dispersion of polymer particles in an aqueous medium. Heading 4002 covers synthetic rubber, and subheading 4002.11 is specifically designated for SBR and carboxylated SBR in latex form. This classification is distinct from solid SBR because the physical state of the material—being a liquid dispersion—changes its handling, usage, and tariff treatment. SBR latex is widely used in industrial applications such as textile coatings, carpet backings, and paper saturation, where a liquid application of the elastomer is required. The classification is determined by the chemical composition (styrene and butadiene) and the physical form (aqueous dispersion).

Products Included

• SBR latex liquid
• Carboxylated SBR latex (XSBR latex)
• Cold SBR latex
• High-styrene SBR latex
• Synthetic rubber latex dispersions

Common Misclassification

SBR latex is frequently misclassified under HS code 4002.19, which is the code for solid SBR (bales, sheets, or strips). The distinction is purely based on the physical state of the rubber. It is also sometimes confused with natural rubber latex, which is classified under HS code 4001.10. Furthermore, if the latex has been compounded with vulcanizing agents or accelerators to the point where it is ready for a specific manufacturing process, it might be argued to fall under 4005 (compounded rubber), though 4002.11 generally covers most raw synthetic latex dispersions.

FAQ

What is the HS code for Styrene-butadiene rubber latex?

The HS code for Styrene-butadiene rubber (SBR) latex is 4002.11.

How is SBR latex different from natural latex in the HS system?

SBR latex is synthetic and classified under 4002.11, while natural rubber latex is harvested from trees and classified under 4001.10.
