8708.70.45.46 - Wheels having a diameter of at least 57 cm but not more than 63 cm

This HTS classification, 8708.70.45.46, specifically covers road wheels designed for motor vehicles, which are constructed from aluminum and have a diameter falling within the range of at least 57 cm but not more than 63 cm. These wheels are intended for use as parts and accessories of vehicles classified under headings 8701 through 8705, excluding railway or tramway rolling stock. The emphasis on aluminum construction and precise dimensional parameters is crucial for distinguishing these wheels from other aluminum road wheels and related components.

This category is distinct from its sibling, 8708.70.45.48, which encompasses "Other" aluminum road wheels not meeting the specified diameter criteria. Therefore, the key differentiator for 8708.70.45.46 is the precise measurement of the wheel's diameter. If a road wheel is made of aluminum and falls outside this specific diameter range, it would be classified under the "Other" subcategory.

As this is a leaf node within the HTS structure, there are no further subcategories. Classification decisions at this level rely on a direct assessment of the product's material (aluminum) and its diameter against the defined range. This level of specificity ensures accurate tariff application for aluminum road wheels of this particular size, preventing misclassification with wheels of different diameters or materials.
