Last updated: April 2026 dataSplit-system air conditioners, multi-zone mini-splits, chiller-based central systems, and other air conditioning equipment not captured by the window/wall self-contained heading are grouped here, making this a broadly traded category central to commercial construction, industrial process cooling, and residential HVAC markets. Split-system and variable-refrigerant-flow (VRF) equipment from leading Asian manufacturers has been subject to antidumping and Section 301 scrutiny, and importers should verify the current trade-remedy status of specific product configurations. DOE minimum efficiency standards and EPA refrigerant regulations apply at entry.

VRF systems, which use a single outdoor condensing unit connected to multiple indoor air-handling units via refrigerant piping, generally classify under this NES heading rather than the self-contained window/wall heading, because the components are not housed in a single enclosure. Importers should confirm classification at the HTS level with a licensed customs broker, as outdoor and indoor units may enter under different subheadings.
Importers of pre-charged split systems must be prepared to demonstrate that the refrigerant used complies with EPA regulations under the Clean Air Act, including any applicable SNAP (Significant New Alternatives Policy) approvals. Manufacturer declarations specifying the refrigerant type and charge weight, along with evidence of EPA-compliant handling procedures, are standard documentation for customs and EPA review.
