8415.10.30 - Self-contained

This HTS category, 8415.10.30, specifically covers "self-contained" air conditioning machines designed for installation in a window, wall, ceiling, or floor. The term "self-contained" signifies that all essential components of the air conditioning unit – including the compressor, condenser, evaporator, and fan – are integrated within a single housing. These units are engineered for direct installation into structural openings or direct mounting, eliminating the need for external refrigerant line connections between separate indoor and outdoor units, which are characteristic of "split system" air conditioners.

This classification is distinguished from its sibling category, "Other," which would encompass air conditioning machines of the specified type that do not fit the "self-contained" description. Therefore, if an air conditioning unit is designed to be fixed in a window, wall, ceiling, or floor but consists of two or more separately housed components connected by refrigerant lines, it would fall under the "Other" classification at this level.

Within the "self-contained" designation, further subclassification is based on the cooling capacity of the unit, measured in kilowatts (kW) per hour. The subcategories are: 8415.10.30.40 for units less than 2.93 kW per hour, 8415.10.30.60 for units with a capacity of 2.93 kW per hour or greater but less than 4.98 kW per hour, and 8415.10.30.80 for units with a capacity of 4.98 kW per hour or greater. This tiered approach allows for granular classification based on the operational power and intended application of the self-contained air conditioning systems.
