8415.81.01 - Incorporating a refrigerating unit and a valve for reversal of the cooling/heat cycle (reversible heat pumps)

This HTS category encompasses air conditioning machines that are specifically designed as reversible heat pumps. These units incorporate a refrigerating system that allows for both cooling and heating functions. A key defining characteristic is the presence of a valve, often referred to as a reversing valve, which facilitates the reversal of the refrigeration cycle to achieve either cooling or heating. This makes them suitable for year-round climate control in various applications.

Distinguishing this category from its siblings, 8415.81.01 is exclusively for reversible heat pumps. Its sibling 8415.82.01 also incorporates a refrigerating unit but does not necessarily possess the functionality for reversing the cooling/heat cycle, meaning it would likely operate only for cooling. The other sibling, 8415.83.00, covers air conditioning machines that do not include a refrigerating unit at all.

Within this classification, a further subdivision exists for "Self-contained" units, identified by the subheading 8415.81.01.30. This indicates that further classification may be required based on whether the entire air conditioning system, including the refrigerating unit, compressor, and controls, is housed within a single cabinet or casing.
