7322.90.00.45 - Parts of air heaters and hot air distributors

This HTS category, 7322.90.00.45, specifically encompasses parts of air heaters and hot air distributors that are not electrically heated. It is crucial to understand that this classification pertains exclusively to components and not complete units. These parts are designed to be incorporated into air heating systems or devices that distribute heated air, often utilizing a motor-driven fan or blower as indicated in the broader heading.

Distinguishing this category from its siblings is essential for accurate classification. HTS code 7322.90.00.15 covers complete air heaters that incorporate a motor-driven fan or blower, while 7322.90.00.30 covers complete hot air distributors with similar fan/blower functionality. This category, 7322.90.00.45, is therefore reserved for the individual components, such as casings, baffles, mounting brackets, or other structural elements that are clearly identifiable as belonging to these larger non-electrically heated air heating or distributing units.

As this is a leaf node within the HTS structure, there are no further subcategories to introduce. Classification within 7322.90.00.45 relies on the determination that an imported article is a component part, rather than a finished air heater or hot air distributor, and that the final product itself falls under the scope of heading 7322 concerning non-electrically heated apparatus of iron or steel incorporating a motor-driven fan or blower.
