HS Code 8415.81 – Air conditioning machines; containing a motor driven fan, other than window or wall types, incorporating a refrigerating unit and a valve for reversal of the cooling/heat cycle (reversible heat pumps)
HS code 8415.81 is the 6-digit subheading for air conditioning machines, containing a motor driven fan, other than window or wall types, incorporating a refrigerating unit and a valve for reversal of the cooling/heat cycle (reversible heat pumps). It is used for air-source heat pumps, ground-source heat pumps, variable refrigerant flow (VRF) systems, ductless mini-split heat pumps and central heat pump systems.
What HS 8415.81 covers
This category covers air conditioning machines that incorporate a refrigerating unit and a valve for reversing the cooling/heat cycle, commonly known as reversible heat pumps. These versatile systems can both heat and cool spaces, making them highly energy-efficient and increasingly popular for residential, commercial, and industrial applications. International trade is booming due to global efforts towards decarbonization, government incentives for energy-efficient heating, and advancements in heat pump technology. Exporters are typically leading HVAC manufacturers, while importers are countries actively transitioning away from fossil fuel-based heating. The market is characterized by innovations in efficiency, smart controls, and integration with renewable energy sources, positioning them as a key technology for sustainable building climate control.

Codes often confused with 8415.81
Common mistake. Distinct from non-reversible AC units (841582) as they explicitly include the reversal valve for heating, and from dedicated heating systems (8403).
Top exporters and importers of HS code 841581, 2025
In 2025, the largest exporter of HS code 841581 in UN Comtrade data was Thailand, with 31% of world exports; the largest importer in UN Comtrade data was the United States, with 14% of world imports. Countries that did not report 2025 data are estimated from partner records, which can understate them.

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).
