7225.40.51.60 - Other

This classification covers flat-rolled products of other alloy steel, exceeding 600 mm in width, that have been hot-rolled and are not in coils. Specifically, these products have a thickness of less than 4.75 mm and are made from tool steel. Tool steel, in this context, refers to specialized alloy steels designed for use in tools such as dies, drills, cutters, and molds, owing to their hardness, wear resistance, and ability to retain edge.

This category is distinguished from its sibling categories by the specific type of alloy steel. While 7225.40.51.10 pertains to high-speed steel, known for its ability to maintain hardness at elevated temperatures during machining, and 7225.40.51.30 relates to ball-bearing steel, which requires excellent toughness and fatigue resistance, this classification focuses solely on products manufactured from other types of tool steel. The defining characteristic here is the metallurgical composition tailored for tooling applications beyond those covered by high-speed or ball-bearing steel.

As this is a leaf node, there are no further subdivisions within this HTS code. Therefore, the classification hinges entirely on the material being classified as "other" tool steel, meeting the specified dimensions (width of 600 mm or more, thickness less than 4.75 mm), and being in a "not further worked than hot-rolled, not in coils" condition. Importers and exporters must ensure that the steel's composition and intended use align with the definition of tool steel, distinct from high-speed or ball-bearing steels, to correctly apply this classification.
