7224.90.00 - Other

This category, HTS Code 7224.90.00, encompasses "Other" semi-finished products of alloy steel, excluding those in their primary forms. Unlike the sibling category 7224.10.00, which specifically covers ingots and other initial shapes like billets or blooms, this designation applies to alloy steel that has undergone further processing beyond the initial casting stage. This typically includes products such as bars, rods, wire rods, or coils that have been hot-rolled, cold-rolled, or otherwise formed but have not yet reached their final manufactured shape or dimension.

The defining characteristic for classification under 7224.90.00 is that the alloy steel is in a semi-finished state and does not fall into the "ingots or other primary forms" category. The term "other alloy steel" here refers to steels containing significant quantities of alloying elements beyond carbon, such as nickel, chromium, molybdenum, vanadium, or tungsten, which impart specific properties like increased strength, hardness, corrosion resistance, or heat resistance.

This "Other" category serves as a residual classification for semi-finished alloy steel products that do not fit into more specific subcategories. In this instance, the subsequent subdivisions are designed to further refine the classification based on the specific type of alloy steel. For example, a distinction is made for high-nickel alloy steel products, indicating that the remaining subcategories will address other types of alloy steel semi-finished products not specifically identified as high-nickel.
