U.S. imports of air conditioning machines with refrigerating unit & reversible heat pump valve (not elsewhere specified) (HS 841581) totaled $52.4M in April 2026, traded with 22 countries.
Importers of Air Conditioning Machines with Refrigerating Unit & Reversible Heat Pump Valve (Not Elsewhere Specified) paid $10.9M in duties in April 2026 — an effective duty rate of 23% on $47.6M in dutiable value, based on actual customs collections rather than the published tariff schedule. Air Conditioning Machines with Refrigerating Unit & Reversible Heat Pump Valve (Not Elsewhere Specified) imports of $52.4M in April 2026 ran 24% above the year-to-date monthly average of $42.3M.
Last updated: April 2026 dataReversible heat pump air conditioners — units that incorporate both a refrigerating unit and a four-way valve enabling the cooling/heating cycle to be reversed — are the defining feature of this heading. The US schedule splits coverage by whether the unit is self-contained and by capacity: self-contained units below 17.58 kW/hr (8415810110), self-contained units above that threshold (8415810120), and non-self-contained configurations (8415810130). Mexico and Canada lead US import supply. These products are subject to DOE minimum efficiency standards for heat pumps, and importers should confirm AHRI certification or equivalent test data is available prior to entry.
AI-written summary of the official U.S. Census Bureau trade figures on this page — verify before relying on it.
The unit must incorporate a valve that allows reversal of the cooling and heating cycle — commonly a four-way reversing valve — in addition to a refrigerating unit. Units with a refrigerating unit but no reversing valve capability fall under 841582. Manufacturer technical datasheets or refrigerant circuit diagrams are the most reliable documentation to support this distinction at entry.
The 17.58 kW/hr (approximately 60,000 BTU/hr) breakpoint separates smaller self-contained units (8415810110) from larger ones (8415810120). The rated cooling or heating capacity stated on the manufacturer's nameplate or in the product specification sheet is used to determine which line applies. Importers should ensure that the capacity figure on the commercial invoice matches the technical documentation to avoid classification disputes.
