8482.20.00.64 - With cups having an outside diameter exceeding 203 mm but not exceeding 305 mm

This HTS classification, 8482.20.00.64, specifically covers tapered roller bearings where the cups exhibit an outside diameter greater than 203 millimeters but not exceeding 305 millimeters. These bearings are designed to accommodate both radial and axial loads, with their conical rollers and raceways enabling efficient load distribution. The precise diameter range of the cup is the defining characteristic for this particular classification.

Distinguishing this category from its siblings, 8482.20.00.40 applies to tapered roller bearings with cups having an outside diameter not exceeding 102 mm, and 8482.20.00.61 covers those with cups measuring between 102 mm and 203 mm. The sibling category 8482.20.00.67 encompasses other tapered roller bearings that do not fit the defined diameter ranges of the preceding subheadings. Therefore, 8482.20.00.64 occupies a specific niche within the broader category of tapered roller bearings based on the external dimension of their cups.

As this is a leaf node, there are no further subcategories to introduce. The classification is finalized at this level based on the diameter criteria of the bearing cup. This ensures accurate tariff application for tapered roller bearings falling within this distinct size range.
