HS Code 2711.29 – Petroleum gases and other gaseous hydrocarbons; in gaseous state, other than natural gas
HS code 2711.29 is the 6-digit subheading for petroleum gases and other gaseous hydrocarbons, in gaseous state, other than natural gas. It is used for refinery gas, gaseous ethane, gaseous propane (not liquefied), gaseous butanes (not liquefied) and gaseous ethylene (not liquefied).
What HS 2711.29 covers
This category covers various petroleum gases and other gaseous hydrocarbons in their gaseous state, excluding natural gas. This can include refinery gases, off-gases from petrochemical processes, and other industrial gaseous streams that are not liquefied. These gases are often used as fuel within industrial facilities, as feedstocks for chemical production, or sometimes for local energy supply. International trade in these specific gaseous forms is less common than for liquefied gases or pipeline natural gas, as transport is more challenging without liquefaction or dedicated pipelines. Trade typically occurs between neighboring countries or within integrated industrial complexes, driven by specific industrial demands and energy recovery efforts, often involving short-distance pipeline transfers or on-site consumption.

Codes often confused with 2711.29
Common mistake. This code is a residual category for gaseous hydrocarbons and is distinct from 271121 (gaseous natural gas). It's also important to differentiate it from the liquefied forms of these same gases (e.g., 271112 for liquefied propane) as the physical state dictates the classification.
Top exporters and importers of HS code 271129, 2025
In 2025, the largest exporter of HS code 271129 in UN Comtrade data was Nigeria, with 78% of world exports; the largest importer in UN Comtrade data was the United Arab Emirates, with about 45% of world imports. Algeria did not report 2025 data, and its estimate from partner records misses its trade with other countries that did not report: in 2024 that was 100% of its exports here ($1.3B, CEPII BACI), so it may also belong among the top exporters. The Netherlands reports $17.6B of its chapter 27 imports without product detail (confidential), so it may also belong among the top importers. Tunisia did not report 2025 data, and its estimate from partner records misses its trade with other countries that did not report: in 2024 that was 100% of its imports here ($1.3B, CEPII BACI), so it may also belong among the top importers.

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).
