8482.91.00.10 - Of alloy steel

This HTS category, 8482.91.00.10, specifically classifies balls used in the construction of ball bearings when these balls are manufactured from alloy steel. This designation is critical for accurately identifying import and export duties, as the material composition plays a key role in tariff application.

Within the broader classification of "Balls, needles and rollers" for bearings, this subcategory is distinguished from its sibling, 8482.91.00.20 ("Other"). The sibling category would encompass balls for bearings made from materials other than alloy steel, such as carbon steel or ceramics. Therefore, the defining characteristic for 8482.91.00.10 is the explicit use of alloy steel in the fabrication of the bearing balls.

As this is a leaf node, there are no further subcategories. The classification ends here, with the material of alloy steel being the final distinguishing factor for these specific bearing components. When classifying, it is important to verify the material composition of the balls to ensure correct entry under this specific alloy steel designation.
