HS Code for Styrene-butadiene rubber

Styrene-butadiene rubber (SBR) is classified under HS code 4002.19. This classification is found within Chapter 40, which covers rubber and rubber articles. Heading 4002 is specifically for synthetic rubber and factice derived from oils. SBR is a synthetic elastomer produced from a mixture of styrene and butadiene. The classification under 4002.19 is applicable when the SBR is in primary forms (such as bales or blocks) or in plates, sheets, and strip, and specifically when it is not in the form of latex. The distinction between natural rubber (4001) and synthetic rubber (4002) is a primary factor in this classification, followed by the specific chemical composition of the copolymer. SBR is the most widely used synthetic rubber, primarily due to its abrasion resistance and its role as a cost-effective alternative to natural rubber in tire manufacturing and industrial goods.

Products Included

• SBR bales and blocks
• Carboxylated SBR (XSBR) in solid form
• SBR masterbatches
• Unvulcanized SBR sheets
• Oil-extended SBR (OE-SBR)

Common Misclassification

The most common misclassification for SBR is using HS code 4002.11, which is reserved exclusively for SBR in latex form. Importers must distinguish between the liquid dispersion (latex) and the solid form (4002.19). Another error involves natural rubber blends; if the product contains a significant amount of natural rubber, it might be misclassified under 4001. Additionally, finished rubber products like tires or gaskets are classified in their specific headings (e.g., 4011 or 4016) rather than the raw material code 4002.19.

FAQ

What is the HS code for Styrene-butadiene rubber?

The HS code for Styrene-butadiene rubber (SBR) in solid primary forms or sheets is 4002.19.

What is the difference between SBR and XSBR in classification?

Both SBR and carboxylated SBR (XSBR) are classified under the same subheading 4002.19, provided they are not in latex form.
