U.S. imports of air conditioning machines with refrigerating unit (not elsewhere specified) (HS 841582) totaled $152.1M in July 2026, traded with 44 countries.
Importers of Air Conditioning Machines with Refrigerating Unit (Not Elsewhere Specified) paid $20.2M in duties in July 2026 — an effective duty rate of 15% on $132.9M in dutiable value, based on actual customs collections rather than the published tariff schedule. Air Conditioning Machines with Refrigerating Unit (Not Elsewhere Specified) imports of $152.1M in July 2026 ran 22% below the year-to-date monthly average of $195.8M.
Last updated: July 2026 dataAmong the most commercially diverse headings in Chapter 84's HVAC cluster, this subheading covers air conditioners with a refrigerating unit that lack a reversing heat-pump valve — spanning remote-condenser self-contained units, year-round heat/cool units, fan coil units for water-chiller systems, central station air handlers, and dehumidifiers incorporating a refrigerating unit. Dehumidifiers are further split by water-removal rate: below 35 liters per 24 hours (8415820155) and above (8415820160), a distinction that aligns with DOE efficiency rulemaking for portable and whole-home dehumidifiers. Mexico and Canada are the leading import sources. Importers of dehumidifiers should confirm DOE certification compliance before shipment, as enforcement at the border has increased for this product category.

Three lines address refrigerating dehumidifiers: a general line (8415820150), one for units removing less than 35 liters of water per 24 hours (8415820155), and one for units removing more than 35 liters per 24 hours (8415820160). The water-removal rate at rated conditions, as stated in the product specification sheet, determines which line applies. This breakpoint corresponds to DOE efficiency standard tiers, so accurate capacity documentation also supports regulatory compliance.
Yes. Room fan coil units for use with water chillers (8415820130) and central station air handlers used with water chillers (8415820135) are carved out as distinct lines, separate from self-contained or remote-condenser air conditioners. These units do not contain their own refrigerating circuit; they rely on chilled water supplied by a separate chiller plant, which is the key technical distinction supporting their separate classification.
