7225.30.51.10 - Of high-speed steel

This HTS subcategory, 7225.30.51.10, specifically classifies flat-rolled products of other alloy steel that are not further worked than hot-rolled, are supplied in coils, have a thickness of less than 4.75 mm, and are characterized by their composition of high-speed steel. High-speed steel is a type of tool steel known for its hardness, wear resistance, and ability to retain its hardness at elevated temperatures, making it suitable for cutting tools and other applications requiring high performance.

This classification is distinct from its sibling category, 7225.30.51.80, which covers "Other" tool steels not meeting the specific criteria for high-speed steel. The defining characteristic here is the explicit identification of the material as high-speed steel, a specialized alloy with specific metallurgical properties that differentiate it from other types of tool steel classified within the broader category.

As this is a leaf node, there are no further subcategories for this HTS code. The classification is finalized at this level based on the material (high-speed steel), form (flat-rolled, in coils), processing (hot-rolled, not further worked), and thickness (less than 4.75 mm). Any product meeting all these criteria will be classified under this specific HTS code.
