8414.30 - Compressors of a kind used in refrigerating equipment (including air conditioning):

This HTS category, 8414.30, specifically encompasses compressors designed for use within refrigerating equipment. This includes a broad range of refrigeration systems, from domestic refrigerators and freezers to commercial display units and industrial cooling systems. The defining characteristic of these compressors is their integral role in the refrigeration cycle, where they compress refrigerant gas to facilitate heat transfer.

Distinguishing 8414.30 from its sibling categories at the 8414 level, it is crucial to note that this sub-heading is exclusively for compressors used in *refrigeration*. For instance, while 8414.10 covers vacuum pumps and 8414.20 covers hand- or foot-operated air pumps, these are functionally and applicationally distinct. Similarly, 8414.40 pertains to air compressors mounted on wheeled chassis for towing, which are typically used for general industrial or construction purposes, not for refrigeration. This section specifically excludes general-purpose air compressors and fans.

The subcategories within 8414.30 differentiate based on the power rating of the compressor. The sub-heading 8414.30.40.00 is for compressors not exceeding 1/4 horsepower, generally found in smaller cooling appliances. The sub-heading 8414.30.80 covers all other compressors in this class, typically those with higher horsepower ratings used in larger commercial or industrial refrigeration applications. This distinction in horsepower is a key criterion for accurate classification within this group.
