8414.90.41.45 - Compressor housings

This HTS classification, 8414.90.41.45, specifically designates compressor housings for air or vacuum pumps, air or other gas compressors, and fans. These housings are integral components designed to enclose and protect the internal mechanisms of compressors, such as pistons, rotors, or impellers. They are typically manufactured from durable materials like cast iron, steel, or aluminum and are engineered to withstand the pressures and operating conditions generated by the compression process. The classification focuses on the housing itself as a distinct part, separate from the complete compressor unit or other ancillary parts.

This category is distinguished from its sibling, 8414.90.41.55 "Other," by its specific focus on the outer casing of the compressor. While 8414.90.41.55 would encompass other non-specified parts of compressors not otherwise enumerated, this sub-subheading precisely identifies the structural enclosure. It is crucial to differentiate these housings from complete compressor assemblies, which fall under a different primary heading.

As this is a leaf node, there are no further subcategories. Classification under 8414.90.41.45 is determined by the item's physical form as a housing for a compressor of subheading 8414.40, and its intended function within such machinery. Therefore, any item meeting these criteria, and not fitting into a more specific classification, would be placed here.
