8414.59.65.60 - Centrifugal

This HTS category, 8414.59.65.60, specifically covers centrifugal fans that are not explicitly classified under any other subheading within the "Other" categories at this level of detail. Centrifugal fans operate by drawing air into their center and expelling it radially outward through the use of a rotating impeller. This mechanism is distinct from axial fans, which propel air parallel to the axis of rotation.

The distinction between this subheading and its sibling, 8414.59.65.90 (Axial), lies directly in their operating principle and airflow direction. While both are types of fans, centrifugal fans are characterized by their outward expulsion of air, often resulting in higher pressure capabilities compared to axial designs which primarily move large volumes of air at lower pressures.

As this is a leaf node within the HTS structure, there are no further subcategories. Therefore, the classification of a centrifugal fan under 8414.59.65.60 depends on it not fitting into any more specific centrifugal fan classifications, nor being an axial fan. Importers and exporters should ensure that the fan's design and function align with the centrifugal principle and that no more specific tariff provisions are applicable.
