8482.10.50.44 - 9 mm and over but not over 30 mm

This HTS classification, 8482.10.50.44, specifically covers single-row radial ball bearings with an outside diameter measuring 9 mm and over, but not exceeding 30 mm. These bearings are designed to support radial loads and are characterized by their inner ring, outer ring, and rolling elements (balls). Their applications span a wide range of industrial and mechanical equipment where precise rotational movement is required within this specific size constraint.

Distinguishing this category from its siblings is crucial for accurate classification. Codes ending in .36 apply to ball bearings with an outside diameter *under* 9 mm, while codes .48, .52, and .56 encompass bearings with outside diameters *over* 30 mm, in progressively larger increments. Therefore, the defining characteristic for 8482.10.50.44 is the precise dimensional range of the outer diameter, falling between 9 mm and 30 mm inclusive.

As this is a leaf node in the HTS classification system, there are no further subcategories to introduce. Classification at this level relies solely on the defined characteristics of the ball bearing, primarily its type (single-row radial ball bearing) and its outside diameter measurement. Careful measurement and comparison to the specified dimensional ranges of sibling categories are therefore essential for correct import and export declarations.
