7226.20.00.00 - Of high-speed steel

This HTS category, 7226.20.00.00, specifically classifies flat-rolled products of other alloy steel that are less than 600 mm in width and are made from high-speed steel. High-speed steel is a type of tool steel known for its high hardness, wear resistance, and ability to retain hardness at elevated temperatures. Products classified here would typically include items like precision cutting tools, drill bits, milling cutters, and other industrial implements where these superior properties are essential.

It is important to distinguish this category from its siblings. "Of silicon electrical steel" covers flat-rolled alloy steel products specifically designed for use in electrical applications, such as transformers and motors, due to their magnetic properties. The "Other" sibling category would encompass any remaining flat-rolled products of other alloy steel (under 600 mm width) that do not meet the specific criteria for high-speed steel or silicon electrical steel. Therefore, the defining characteristic for classification under 7226.20.00.00 is the material composition and inherent properties of high-speed steel.

As this is a leaf node, there are no further subcategories within this specific HTS code. Classification decisions at this level will rely on verifying that the flat-rolled products are indeed made of high-speed steel, are of other alloy steel, and have a width less than 600 mm. The intended use of the product, while often indicative, is secondary to the material composition and physical dimensions for this particular classification.
