7225.30.51.80 - Other

This HTS classification, 7225.30.51.80, specifically designates "Other" 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 classified as "Of tool steel." This category encompasses hot-rolled coils of alloy steel that are intended for the manufacturing of tools and possess the specific characteristics defined within the broader headings. The "tool steel" designation implies these steels have been alloyed to impart specific properties such as hardness, wear resistance, and toughness suitable for cutting, shaping, or forming operations.

This specific subcategory is distinguished from its sibling, 7225.30.51.10, which covers "Of high-speed steel." While both are tool steels, high-speed steel is a specialized type of tool steel characterized by its ability to retain hardness at elevated temperatures during high-speed machining operations. Therefore, the current classification covers tool steels that, while intended for tool applications, do not meet the stringent alloying requirements and performance characteristics of high-speed steels.

As this is a leaf node, there are no further subcategories. Classification within this code is therefore determined by the precise material composition and intended use as tool steel, in conjunction with the physical attributes of being hot-rolled, in coils, and under 4.75 mm in thickness. Importers and exporters should ensure that the steel in question is explicitly intended for tool manufacturing and possesses the characteristic properties of tool steel beyond those of high-speed steel to correctly apply this classification.
