7226.91.25 - Of a width of less than 300 mm

This HTS classification covers flat-rolled products of other alloy steel, specifically those not further worked than hot-rolled and of a width less than 300 mm. These products fall under the broader category of "Other alloy steel" and are distinct from high-speed steel. The key defining characteristic for inclusion in this subcategory is the hot-rolled state and the narrow width.

The primary distinction from its sibling category, 7226.91.15, lies solely in the width. While both encompass other alloy steel products not further worked than hot-rolled, this category specifically addresses those with a width *less than* 300 mm, whereas the sibling covers those with a width of *300 mm or more*. This width criterion is a critical factor in ensuring correct classification.

Within this classification, further subdivisions exist to refine the categorization. The subcategories, 7226.91.25.30 and 7226.91.25.60, distinguish between specialized types of other alloy steel. Specifically, 7226.91.25.30 pertains to ball-bearing steel, a type of alloy steel engineered for high performance in rolling element bearings. The "Other" subcategory captures all remaining flat-rolled products of other alloy steel meeting the width and hot-rolled criteria that do not fit the more specific ball-bearing steel designation.
