HS Code 7322.90 – Air heaters and hot air distributors, (not electrically heated), incorporating a motor-driven fan or blower and parts thereof, of iron or steel
HS code 7322.90 is the 6-digit subheading for air heaters and hot air distributors, (not electrically heated), incorporating a motor-driven fan or blower and parts thereof, of iron or steel. It is used for industrial unit heaters, warm air furnaces (non-electric), suspended gas heaters, workshop heaters and air handling units (heating section).
What HS 7322.90 covers
This HS code covers non-electrically heated air heaters and hot air distributors made of iron or steel, which incorporate a motor-driven fan or blower, along with their parts. This category is crucial for industrial, commercial, and large-scale residential heating applications where forced air circulation is required for efficient heat distribution. Think of unit heaters in warehouses, factories, or large workshops. The trade in these goods is primarily business-to-business, involving manufacturers, distributors, and HVAC installers. Importers seek robust, energy-efficient systems that can withstand demanding environments and comply with local safety and environmental regulations. Exporters leverage expertise in fan technology, combustion engineering, and metal fabrication. Key aspects of trade include system integration, energy consumption, and the ability to heat large volumes of space effectively, making them distinct from radiant heating solutions.

Codes often confused with 7322.90
Common mistake. Can be confused with 8415 (air conditioning machines) if cooling functions are present, or 841459 (other fans) if the heating element isn't the primary function. The defining feature is the integrated motor-driven fan for hot air distribution.

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).
