HS Code for Compressed air
Compressed air is classified under HS code 2853.90. This heading covers other inorganic compounds, including liquid air and compressed air. The classification is based on the chemical nature of air as a mixture of inorganic gases (primarily nitrogen and oxygen). Heading 2853 is a residual heading for inorganic chemicals and compounds that do not fit into more specific categories within Chapter 28. Compressed air is distinct from pure gases because it maintains the atmospheric ratio of gases, though it is pressurized for storage or transport in cylinders. This code also encompasses liquid air from which rare gases may or may not have been removed, provided it has not been separated into its pure component gases.
Products Included
- Compressed atmospheric air in cylinders
- Liquid air for industrial cooling
- Compressed air for breathing apparatus (scuba/firefighting)
- Liquid air with rare gases removed
- Inorganic compounds not elsewhere specified
Common Misclassification
Compressed air is frequently confused with HS code 2804, which covers individual chemical elements and rare gases. For example, pure nitrogen is 2804.30 and pure oxygen is 2804.40. If the air has been processed to the point of being pure oxygen or nitrogen, it cannot stay in 2853.90. Another common error is 2711, which is for petroleum gases and other gaseous hydrocarbons like methane or propane. Compressed air contains no hydrocarbons and therefore does not belong in Chapter 27.
FAQ
What is the HS code for compressed air?
