Product classification
HS code for SBR 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 SBR rubber under HS 4002.19
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.

Codes often confused with 4002.19
Common mistake. 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.
Top exporters and importers of HS 400219 (the code used for SBR rubber), 2025
In 2025, the largest exporter of HS 400219 (the code used for SBR 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.
Figures cover everything classified under HS 400219, not only SBR rubber.

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 SBR rubber
What is the HS code for SBR rubber?
The HS code for SBR 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 SBR rubber in primary forms (excluding latex) is 4002.19.
How do I classify SBR rubber for customs?
SBR rubber is classified under HS code 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. This is a 6-digit subheading level code.
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.
Which countries are the top exporters of SBR rubber (HS 400219)?
In 2025, the top exporters of HS 400219 (the code used for SBR 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.
