8414.90.41.80 - Impeller covers and hubs

This HTS classification, 8414.90.41.80, specifically identifies impeller covers and hubs that are classified as parts of compressors. These components are integral to the rotating mechanism of compressors, with impeller covers enclosing the impeller to direct airflow or gas, and hubs serving as the central attachment point for the impeller to the rotating shaft. Their function is to facilitate the compression process by guiding the working fluid and ensuring the structural integrity of the impeller assembly.

Distinguishing this category from its sibling, 8414.90.41.65 (Compressor housings), it's important to note that while both are parts of compressors, this classification focuses on internal rotating components rather than the external casing that encloses the entire compressor unit. The sibling category 8414.90.41.90, "Other," would encompass any remaining compressor parts not specifically enumerated in the preceding subheadings.

As this is a leaf node within the HTS structure, there are no further subcategories to introduce. Therefore, classification within 8414.90.41.80 relies on the precise identification of the imported article as an impeller cover or hub intended for use with a compressor. The absence of further subdivisions emphasizes the specific nature of these components within the broader category of compressor parts.
