Last updated: July 2026 dataForced-air furnace units and hot-air distribution equipment powered by gas or other non-electric fuel sources — incorporating a motor-driven fan or blower — classify here, with the US schedule subdividing the heading into complete air heaters (7322900015), hot air distributors (7322900030), and their parts (7322900045). Mexico and Canada together dominate supply, a pattern consistent with integrated North American HVAC manufacturing supply chains operating under USMCA. Vietnam and Thailand represent growing alternative sources for both finished units and components.

The key criterion is the heat source: 732290 covers units where the heating element is non-electric (gas burner, oil burner, etc.) but which use a motor-driven fan or blower to distribute the heated air. Electrically heated forced-air units classify under Chapter 85 (typically heading 8516). If a unit uses electric resistance heating with a fan, it does not belong here regardless of the fan motor.
Possibly, but blower motors are also classifiable as electric motors under Chapter 85. Classification depends on whether the motor is imported as a dedicated, identifiable part of the furnace assembly or as a general-purpose motor. CBP has issued rulings on this distinction; consult a licensed customs broker and review relevant binding rulings before filing.
