8482.10.10.40 - Bearings having an outside diameter not over 30 mm 🖩

This classification covers ball bearings that have an integral shaft and an outside diameter not exceeding 30 millimeters. These are specialized ball bearings where the shaft is a single, unified component with the bearing itself, designed for specific applications requiring integrated rotational support and a shaft for further mechanical connection. Examples include miniature ball bearings used in small electric motors, precision instruments, and certain types of consumer electronics.

This specific subcategory is distinct from its sibling, 8482.10.10.80 ("Other"), which encompasses all other ball bearings with integral shafts regardless of their size. Therefore, the key differentiating factor for this classification is the strict limitation on the outside diameter to 30 mm or less. This size constraint is crucial for precise tariff application, indicating a focus on smaller, often more intricate bearing assemblies.

As this is a leaf node within the HTS classification system, there are no further subcategories to introduce. The classification ends at this granular level, meaning that any ball bearing with an integral shaft and an outside diameter not exceeding 30 mm will fall under this specific HTS code. It is important for importers and exporters to accurately measure and verify the outside diameter of such bearings to ensure correct classification.
