Product classification
HS code for Heat pump: 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).
Classification of heat pump under HS 8415.81
Heat pumps are classified under HS code 8415.81 when they are part of an air conditioning system that incorporates a reversing valve. This code falls under Chapter 84 (Machinery and Mechanical Appliances) and heading 8415 (Air conditioning machines). The classification is highly technical: 8415.81 is reserved for machines that contain a motor-driven fan and elements for changing the temperature and humidity, including those with a valve for reversal of the cooling/heat cycle (reversible heat pumps). This specific sub-heading is used for units that are not of the window or wall-mounted type (which fall under 8415.10). The presence of the reversing valve is the defining characteristic, as it allows the unit to switch from cooling a space to heating it by reversing the flow of refrigerant. If a heat pump is not designed for air conditioning or lacks a reversing valve, it may fall under different codes within heading 8415 or even heading 8418.

Codes often confused with 8415.81
Common mistake. The most common misclassification is HS code 8418.61, which covers heat pumps other than air conditioning machines of heading 8415. The distinction lies in the application: if the device is designed to control the environment for human comfort (air conditioning), it belongs in 8415.81. If it is used for industrial heating or water heating, it belongs in 8418.61. Another error is using 8415.82, which is for units that do not include a reversing valve.
Top exporters and importers of HS 841581 (the code used for heat pump), 2025
In 2025, the largest exporter of HS 841581 (the code used for heat pump) 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).
