HS Code for Gas liquefier

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.

Products Included

• Industrial air liquefaction plants
• Nitrogen liquefiers
• LNG (Liquefied Natural Gas) liquefaction units
• Cryogenic gas liquefaction machinery
• Apparatus for the liquefaction of rare gases

Common Misclassification

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.

FAQ

What is the HS code for gas liquefier?

The HS code for machinery used for liquefying air or other gases is 841960.

Does this code include domestic refrigerators?

No, domestic refrigerators are classified under HS code 8418. Heading 841960 is strictly for industrial gas liquefaction machinery.
