7322.90.00 - Other, including parts

This HTS category, 7322.90.00, covers "Other" articles of iron or steel within the broader group of radiators and air heating equipment. This specifically encompasses those not electrically heated, that do not fit into the more defined subcategories of radiators or specific types of air heaters and hot air distributors. Essentially, it acts as a residual category for parts and other articles related to central heating, air heating, and hot air distribution systems made from iron or steel, which are not explicitly classified elsewhere under heading 7322.

Distinguishing this category from its sibling, "Radiators and parts thereof," is crucial. While the sibling focuses solely on radiators designed for central heating, this category 7322.90.00 captures the remaining "other" items. This means it will include components or complete units that are part of the heating system but are not the radiator itself, nor the motor-driven fan and blower units specifically addressed in the subcategories.

Within this "Other" classification, further subdivisions exist to provide greater specificity. Category 7322.90.00.15 covers air heaters that incorporate a motor-driven fan or blower but are not electrically heated. Similarly, 7322.90.00.30 addresses hot air distributors, also without electrical heating and featuring a motor-driven fan or blower. Finally, 7322.90.00.45 is dedicated to parts specifically for these motor-driven air heaters and hot air distributors, ensuring comprehensive classification of all components within this functional group.
