Product classification
HS code for Gas liquefier: 8419.60
Machinery, for liquefying air or gas, not used for domestic purposes.
Classification of gas liquefier under HS 8419.60
A gas liquefier is classified under HS code 841960. This code falls under Chapter 84, which covers nuclear reactors, boilers, machinery, and mechanical appliances. Heading 8419 specifically addresses machinery and plant equipment for the treatment of materials by a process involving a change of temperature, such as heating, cooking, roasting, or liquefying. Subheading 841960 is reserved for machinery used for liquefying air or other gases. These are typically industrial-scale machines used in cryogenic applications, the production of liquid nitrogen, or the liquefaction of natural gas (LNG). The classification excludes machinery used for domestic purposes, which would fall under different headings. The primary function of the machine—changing the physical state of a gas to a liquid through thermal management—is the deciding factor for this HS code.

Codes often confused with 8419.60
Common mistake. Gas liquefiers are often misclassified under HS code 8414, which covers air or vacuum pumps and gas compressors. While liquefaction systems often include compressors, the complete system for liquefaction is classified by its thermal process under 8419. Another common error is using 8418, which covers refrigerators and freezers. While both involve cooling, 8418 is for the maintenance of low temperatures in a cabinet, whereas 841960 is for the specific industrial process of changing a gas's state. Additionally, laboratory-scale equipment might sometimes be confused with 841989, but 841960 is the more specific code for liquefaction.
Top exporters and importers of HS 841960 (the code used for gas liquefier), 2025
In 2025, the largest exporter of HS 841960 (the code used for gas liquefier) in UN Comtrade data was China, with 40% 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 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).
