7225.50.11.10 - Of high-speed steel

This HTS category, 7225.50.11.10, specifically classifies flat-rolled products of other alloy steel that meet the following criteria: they are 600 mm or wider, have undergone no further working than cold rolling (cold-reduction), and are composed 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 even at elevated temperatures, making it suitable for cutting tools and high-performance applications.

This classification is distinct from its sibling categories. Specifically, 7225.50.11.30 covers similar flat-rolled products made of ball-bearing steel, which is optimized for load-bearing components in rolling element bearings. The sibling category 7225.50.11.60, "Other," serves as a residual category for flat-rolled products of other alloy steel that do not fit into the specific subcategories of tool steel (including high-speed steel) or ball-bearing steel.

As this is a leaf node in the HTS structure, there are no further subcategories for this specific code. Therefore, classification under 7225.50.11.10 hinges on the definitive presence of high-speed steel as the alloying element, alongside the established criteria of width (600 mm or more) and cold-rolled processing. Accurate material composition analysis is critical for correct classification within this precise subcategory.
