7226.91.15.30 - Of ball-bearing steel

This HTS subcategory, 7226.91.15.30, specifically classifies flat-rolled products of other alloy steel, less than 600 mm in width, which have not been further worked than hot-rolled, and are made of ball-bearing steel. Ball-bearing steel is a high-carbon chromium alloy steel renowned for its exceptional hardness, wear resistance, and ability to withstand high compressive loads, making it ideal for the manufacture of rolling-element bearings. The "other alloy steel" designation here means it's not high-speed steel or tool steel (other than high-speed steel), but rather an alloy steel where ball-bearing characteristics are the primary distinguishing feature.

The primary distinction for this category lies in its specific material composition: ball-bearing steel. While its sibling category, 7226.91.15.60 ("Other"), encompasses other alloy steels not further specified as ball-bearing steel, this node is exclusively for those products manufactured with the precise metallurgical properties required for bearing applications. Both fall under the broader classification of hot-rolled, flat-rolled products of other alloy steel with a width of 300 mm or more, but the defining characteristic here is the intended and actual use of the steel as ball-bearing steel.

As this is a leaf node in the HTS classification structure, there are no further subcategories under 7226.91.15.30. Therefore, the focus for classification purposes is on the accurate identification of the material as ball-bearing steel, and that the product meets all preceding criteria: flat-rolled, of other alloy steel, less than 600 mm in width, not further worked than hot-rolled, and of a width of 300 mm or more. Importers must ensure that the steel's composition and properties align with established standards for ball-bearing steel.
