HS code for Styrene-butadiene rubber: 4002.19

Rubber, synthetic, styrene-butadiene rubber (SBR) and carboxylated styrene-butadiene rubber (XSBR), (other than latex), in primary forms or in plates, sheets or strip.

Classification of styrene-butadiene rubber under HS 4002.19

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.

Covers
  • SBR bales and blocks
  • Carboxylated SBR (XSBR) in solid form
  • SBR masterbatches
  • Unvulcanized SBR sheets
  • Oil-extended SBR (OE-SBR)
Also under 4002.19
  • Trinseo SBR
  • Synthos SBR
  • Lanxess SBR
  • Michelin Green X tires (component)
  • Goodyear Assurance tires (component)

Codes often confused with 4002.19

Common mistake. 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.

Top exporters and importers of HS 400219 (the code used for styrene-butadiene rubber), 2025

In 2025, the largest exporter of HS 400219 (the code used for styrene-butadiene rubber) in UN Comtrade data was South Korea, with 17% of world exports; the largest importer in UN Comtrade data was China, with 17% of world imports. Countries that did not report 2025 data are estimated from partner records, which can understate them.

How these figures are built

109 countries reported 2025 trade to UN Comtrade in HS 2022, and their own totals are used. Countries that did not report are estimated from what other countries recorded trading with them. Those estimates miss trade with other non-reporting countries, so they can be low, and a non-reporting country can rank higher than shown or be missing from the list. World totals add both and leave out trade between two non-reporting countries. Figures are in current US dollars; reported imports are mostly valued CIF and exports FOB, and exports include re-exports. The UN Comtrade links show the underlying records; they can also list a few reporters left out here (regional groups and older HS editions).

Questions about styrene-butadiene rubber

What is the HS code for Styrene-butadiene rubber?

The HS code for Styrene-butadiene rubber is 400219 (Rubber; synthetic, styrene-butadiene rubber (SBR) and carboxylated styrene-butadiene rubber (XSBR), (other than latex), in primary forms or in plates, sheets or strip). The HS code for Styrene-butadiene rubber (SBR) in solid primary forms or sheets is 4002.19.

How do I classify Styrene-butadiene rubber for customs?

Styrene-butadiene rubber is classified under HS code 400219 โ€” Rubber; synthetic, styrene-butadiene rubber (SBR) and carboxylated styrene-butadiene rubber (XSBR), (other than latex), in primary forms or in plates, sheets or strip. This is a 6-digit subheading level code.

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.

Which countries are the top exporters of styrene-butadiene rubber (HS 400219)?

In 2025, the top exporters of HS 400219 (the code used for styrene-butadiene rubber) in UN Comtrade data were South Korea ($1.1B, 17% of world exports), China ($683M) and Germany ($645M). World exports came to about $6.3B, adding countries' reported figures and partner-based estimates for those that did not report (UN Comtrade data). Countries that did not report 2025 data are estimated from partner records, which can understate them.

Which countries are the top importers of styrene-butadiene rubber (HS 400219)?

In 2025, the top importers of HS 400219 (the code used for styrene-butadiene rubber) in UN Comtrade data were China ($1.1B, 17% of world imports), the United States ($573M) and Thailand ($451M). World imports came to about $6.8B, adding countries' reported figures and partner-based estimates for those that did not report (UN Comtrade data). Countries that did not report 2025 data are estimated from partner records, which can understate them.

Is the HS code for Styrene-butadiene rubber the same in all countries?
