7226.91.15 - Of a width of 300 mm or more

This HTS category, 7226.91.15, specifically covers flat-rolled products of other alloy steel that have a width of 300 mm or more, and are not further worked than hot-rolled. These materials fall under the broader classification of other alloy steel, distinguishing them from categories dedicated to specific types like stainless steel or high-speed steel. The key defining characteristic for inclusion here is the minimum width of 300 mm, a crucial metric for customs classification.

Within the "Other" sub-heading for hot-rolled products of other alloy steel, this particular code differentiates itself from its sibling, 7226.91.25, solely based on its width. While 7226.91.15 applies to products with a width of 300 mm or more, the sibling category is for those with a width *less than* 300 mm. Therefore, the physical dimension of the rolled product is the primary determinant for choosing between these two classifications.

This category then further breaks down into two subcategories, 7226.91.15.30 and 7226.91.15.60, to provide more granular classification. The "Of ball-bearing steel" subcategory is for specialized alloy steels known for their use in bearing components, requiring specific material properties. The "Other" subcategory is a residual classification for any other alloy steel flat-rolled products meeting the width and hot-rolled criteria that do not qualify as ball-bearing steel.
