HS Code 4002.20 – Rubber; synthetic, butadiene rubber (BR), in primary forms or in plates, sheets or strip
HS code 4002.20 is the 6-digit subheading for rubber, synthetic, butadiene rubber (BR), in primary forms or in plates, sheets or strip. It is used for BR bales, BR pellets, BR sheets, BR compounds and high-cis BR.
What HS 4002.20 covers
This HS code encompasses synthetic butadiene rubber (BR) in primary forms, such as bales, sheets, or strips. BR is a critical synthetic rubber known for its high elasticity, low heat buildup, and excellent abrasion resistance, making it indispensable for tire treads, sidewalls, and golf ball cores. Global trade involves major chemical manufacturers supplying BR to tire companies and other rubber product fabricators worldwide. The demand for BR is intrinsically linked to the automotive industry's production cycles and the continuous need for fuel-efficient, durable, and high-performance tires. Key considerations in this trade include the availability and pricing of butadiene monomer, and the ongoing innovation in tire technology requiring specific BR grades.

Codes often confused with 4002.20
Common mistake. Often confused with SBR (400219) due to both being primary tire rubbers, but BR offers superior elasticity and abrasion resistance. It can also be mistaken for natural rubber (4001) if not clearly identified as synthetic.
Top exporters and importers of HS code 400220, 2025
In 2025, the largest exporter of HS code 400220 in UN Comtrade data was South Korea, with 17% of world exports; the largest importer in UN Comtrade data was China, with 13% 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 marked * did not, so their figures add up what other countries recorded trading with them, and their exports are valued at buyers' CIF prices. 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).

Key considerations in this trade include the availability and pricing of butadiene monomer, and the ongoing innovation in tire technology requiring specific BR grades.
What products fall under HS code 400220?
BR bales, BR pellets, BR sheets, BR compounds, High-cis BR, Low-cis BR, Neodymium BR
What are common misclassifications for HS code 400220?
Often confused with SBR (400219) due to both being primary tire rubbers, but BR offers superior elasticity and abrasion resistance. It can also be mistaken for natural rubber (4001) if not clearly identified as synthetic.
Which countries are the top exporters of goods under HS code 400220?
In 2025, the top exporters of HS code 400220 in UN Comtrade data were South Korea ($601M, 17% of world exports), China ($506M) and the United States ($450M). World exports came to about $3.6B, adding countries' reported figures and partner-based estimates for those that did not report (UN Comtrade data).
