8414.90.10.40 - Of fans of subheading 8414.51

This HTS category, 8414.90.10.40, specifically covers parts designed for use with fans, including blowers, and ventilating or recycling hoods that are classified under subheading 8414.51. This means that any component or accessory intended to be a constituent part of these types of fans or hoods falls within this designation. Examples include fan blades, motor housings specifically for these fans, impellers, or grilles made for these particular fan units.

This category is distinguished from its sibling, 8414.90.10.80 ("Other"), which would cover parts for other types of machinery within the broader 8414.90 "Parts" classification that are not specifically related to fans as defined in 8414.51. Therefore, the key differentiating factor is the intended application and the specific type of fan or hood the part is designed to be integrated with.

As this is a leaf node, there are no further subcategories. Classification within this code requires a direct determination that the part in question is exclusively or primarily intended for use with the fans and hoods detailed in subheading 8414.51. If a part could be used with a wider range of machinery, it would likely fall under a more general "parts" classification.
