Product classification
HS code for Heat pump water heater: 8418.61
Heat pumps, other than air conditioning machines of heading no. 8415.
Classification of heat pump water heater under HS 8418.61
Heat pump water heaters are classified under HS code 8418.61 because they utilize a refrigeration cycle to transfer thermal energy from the ambient air to water. Unlike traditional electric resistance heaters, these devices function as heat pumps. Heading 8418 specifically covers refrigerators, freezers, and other refrigerating or freezing equipment, including heat pumps. Subheading 8418.61 is designated for heat pumps other than air conditioning machines of heading 8415. The classification is determined by the functional principle of the device—using a compressor and refrigerant circuit—rather than just the end result of heating water. This distinguishes them from instantaneous or storage water heaters found in heading 8419, which typically rely on heat exchange or direct heating elements without a refrigeration cycle. According to the General Rules of Interpretation (GRI) 1 and 6, the specific technology of the heat pump takes precedence over the general function of water heating when a dedicated code for heat pumps exists.

Codes often confused with 8418.61
Common mistake. These products are frequently misclassified under HS code 8419.19, which covers other instantaneous or storage water heaters. The confusion arises because both products serve the same purpose. However, 8419 is reserved for non-refrigeration based heating. Another common error is 8415.81, which applies to air conditioning machines; while they share similar technology, 8415 is for temperature control of air in a space, not water.
Top exporters and importers of HS 841861 (the code used for heat pump water heater), 2025

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).
