U.S. imports of evaporative air coolers (HS 847960) totaled $76.7M in July 2026, traded with 23 countries.
Importers of Evaporative Air Coolers paid $338K in duties in July 2026 — an effective duty rate of 13% on $2.6M in dutiable value, based on actual customs collections rather than the published tariff schedule. Evaporative Air Coolers imports of $76.7M in July 2026 ran 11% above the year-to-date monthly average of $69.4M.
Last updated: July 2026 dataEvaporative air coolers — commonly called swamp coolers — use water evaporation rather than refrigerant compression to reduce air temperature, making them energy-efficient alternatives to conventional air conditioning in low-humidity climates. All US imports enter under a single tariff line (8479600000), and goods sourced from China carry Section 301 tariff exposure. Canada and Mexico are the leading supply sources, with China also a notable origin. Importers should confirm that units with integrated refrigeration circuits classify under heading 8415 (air conditioning machines) rather than here.

The critical distinction is the cooling mechanism. Evaporative coolers classified under 8479600000 cool air solely through water evaporation and do not contain a refrigerant circuit or compressor. Units that use a refrigerant-based vapor-compression cycle — even if they also incorporate evaporative pre-cooling — classify under heading 8415 as air conditioning machines. CBP will look to the machine's primary cooling technology and design.
Yes — heading 847960 covers evaporative air coolers regardless of size or portability. Both residential portable units and large industrial or commercial evaporative cooling towers that function on the evaporative principle fall under 8479600000, provided they do not incorporate a refrigerant compression system. Industrial cooling towers that cool process water rather than air may classify differently under heading 8419.
