U.S. imports of compression-type heat pump units with heat exchanger condensers (nesoi) (HS 841861) totaled $10.9M in July 2026, traded with 29 countries.
Importers of Compression-Type Heat Pump Units with Heat Exchanger Condensers (NESOI) paid $1.2M in duties in July 2026 — an effective duty rate of 14% on $8.7M in dutiable value, based on actual customs collections rather than the published tariff schedule. Compression-Type Heat Pump Units with Heat Exchanger Condensers (NESOI) imports of $10.9M in July 2026 ran 28% above the year-to-date monthly average of $8.6M.
Last updated: July 2026 dataCompression-type heat pumps whose condensers function as heat exchangers — but excluding reversible units capable of simultaneously adjusting both temperature and humidity — are classified here, with all US imports entering under a single tariff line (8418610100) that explicitly excludes heading 8415 air-conditioning equipment. Italy leads US supply under this heading, a reflection of that country's strong industrial refrigeration and HVAC equipment manufacturing sector, with China and South Korea as significant secondary sources. Correct classification hinges on distinguishing these units from reversible heat pumps (which fall elsewhere) and from air conditioners under heading 8415 — a distinction that frequently arises in customs audits of HVAC equipment.

Heading 8415 covers air conditioning machines that include a motor-driven fan and equipment for changing air temperature and humidity. Heat pumps under 841861 are specifically excluded from 8415 and are characterized by their use of a refrigerant cycle to transfer heat rather than condition air for human comfort. Technical documentation showing the unit's primary function — heat transfer to a process or space versus air conditioning — is essential to support the classification.
The heading explicitly excludes reversible heat pumps capable of changing both temperature and humidity. Units with that dual-function capability are classified elsewhere in the HTS schedule. Importers should obtain a detailed technical specification confirming whether the unit can reverse its cycle and whether it includes humidity control, as these features shift the classification.
