7225.50 - Other, not further worked than cold-rolled (cold-reduced):

This category, HTS 7225.50, encompasses flat-rolled products of other alloy steel, with a width of 600 millimeters or more, that have undergone cold-rolling (cold-reduction) but have not been further worked. This process involves deforming the steel at or near room temperature, resulting in a smoother surface finish, tighter dimensional tolerances, and increased strength compared to hot-rolled products. "Other alloy steel" refers to iron-based alloys containing one or more alloying elements (such as chromium, nickel, molybdenum, vanadium, or tungsten) in quantities sufficient to impart specific properties.

Distinguishing 7225.50 from its siblings, it specifically covers cold-rolled products. Categories like 7225.30 and 7225.40 are reserved for hot-rolled products. Furthermore, this subcategory is for products *other than* silicon electrical steel, which is classified separately. The "other" designation signifies that it captures a broad range of cold-rolled alloy steel flat products not fitting into more specific classifications within the broader 7225 heading.

Within HTS 7225.50, further subdivisions exist to refine classification based on the type of alloy steel. The subcategory 7225.50.11 specifically identifies products made from tool steel, which is a specialized alloy steel designed for use in tools, dies, and cutting implements due to its hardness, wear resistance, and toughness. The subsequent "Other" subcategory then captures all remaining cold-rolled alloy steel flat products not classified as tool steel, ensuring comprehensive coverage.
