7225.40.11.10 - Of high-speed steel

This HTS classification, 7225.40.11.10, specifically designates flat-rolled products of other alloy steel that are not further worked than hot-rolled and are not in coils. Crucially, these products must have a width of 600 mm or more and a thickness of 4.75 mm or more. The defining characteristic of this subcategory is that the steel is of high-speed steel, which is a type of tool steel renowned for its ability to retain hardness at elevated temperatures, making it ideal for cutting tools.

This category distinguishes itself from its sibling, 7225.40.11.80 ("Other"), by the specific composition of the alloy steel. While both fall under "Of tool steel" at the preceding level, this code narrows the focus exclusively to high-speed steel. Products classified under 7225.40.11.80 would encompass other types of tool steel not meeting the specific criteria for high-speed steel. As this is a leaf node, there are no further subcategories. Therefore, classification hinges on the accurate identification of the steel's composition as high-speed steel, alongside the specified dimensions of the flat-rolled product.
