HS code for Forced air heater: 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.

Classification of forced air heater under HS 7322.90

Forced air heaters are classified under HS code 7322.90. This classification is determined by the construction and function of the device as a non-electric heating unit made of iron or steel. Heading 7322 covers radiators for central heating and air heaters or hot air distributors which incorporate a motor-driven fan or blower. The "forced air" aspect is the defining characteristic that necessitates the inclusion of a fan, distinguishing it from simple convection heaters. To fall under 7322.90, the heater must not be electrically heated; instead, it typically utilizes gas, oil, or other fuels to generate heat, which is then distributed by the integrated blower. The classification remains in Chapter 73 because the primary structure is an article of iron or steel, and the heading specifically describes these mechanical heating distributors. This code is vital for industrial and commercial HVAC equipment that relies on combustion rather than electrical resistance for heat generation.

Codes often confused with 7322.90

Common mistake. Forced air heaters are often misclassified under HS code 8516.29, which covers electric space heating apparatus. If the heating element is electric, it must be in Chapter 85, regardless of the presence of a fan. Another common error is classification under 8419.89, which covers general machinery for the treatment of materials by a change of temperature. However, because 7322 specifically describes air heaters with fans, it takes precedence over the more general machinery heading.

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).
