HS code for Liquefied butadiene: 2711.14
Petroleum gases and other gaseous hydrocarbons, liquefied, ethylene, propylene, butylene and butadiene.
Classification of liquefied butadiene under HS 2711.14
Liquefied butadiene is classified under HS code 2711.14. Chapter 27 covers mineral fuels, mineral oils, and products of their distillation. Heading 2711 specifically addresses petroleum gases and other gaseous hydrocarbons. Within this heading, the code distinguishes between liquefied gases and those in a gaseous state. Sub-heading 2711.14 is reserved for liquefied ethylene, propylene, butylene, and butadiene. Butadiene is a colorless gas that is easily liquefied under pressure and is a crucial industrial chemical, primarily used as a monomer in the production of synthetic rubber. For customs purposes, the purity of the butadiene is a factor; however, if it is presented as a liquefied petroleum gas, 2711.14 is the primary classification. If the butadiene is of a very high purity (usually exceeding 95% or 99% depending on specific regional notes) and is a chemically defined compound, it might be considered for Chapter 29, but 2711 remains the standard for the liquefied fuel and industrial gas trade. The classification follows GIR 1, as the terms of the heading and sub-heading specifically name butadiene in its liquefied form.

Codes often confused with 2711.14
Common mistake. Liquefied butadiene is often confused with HS code 2901.24, which covers butadiene as a chemically defined acyclic hydrocarbon. The choice between Chapter 27 and Chapter 29 often depends on the purity of the product and its intended use. It may also be misclassified under 2711.19, which is the "other" category for liquefied petroleum gases, but 2711.14 is more specific and must be used.
Top exporters and importers of HS 271114 (the code used for liquefied butadiene), 2025
In 2025, the largest exporter of HS 271114 (the code used for liquefied butadiene) in UN Comtrade data was Canada, with 22% of world exports; the largest importer in UN Comtrade data was Belgium, with 24% 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 liquefied butadiene
What is the HS code for Liquefied butadiene?
The HS code for Liquefied butadiene is 271114 (Petroleum gases and other gaseous hydrocarbons; liquefied, ethylene, propylene, butylene and butadiene). The HS code for liquefied butadiene is 2711.14.
How do I classify Liquefied butadiene for customs?
Liquefied butadiene is classified under HS code 271114 — Petroleum gases and other gaseous hydrocarbons; liquefied, ethylene, propylene, butylene and butadiene. This is a 6-digit subheading level code.
How is butadiene classified if it is not liquefied?
If butadiene is in a gaseous state (not liquefied), it is classified under HS code 2711.29, which covers other petroleum gases in gaseous form.
Which countries are the top exporters of liquefied butadiene (HS 271114)?
In 2025, the top exporters of HS 271114 (the code used for liquefied butadiene) in UN Comtrade data were Canada ($249M, 22% of world exports), Germany ($147M) and Belgium ($136M). World exports came to about $1.1B, 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.
