7224.90.00.05 - Of high-nickel alloy steel

This HTS category specifically classifies semi-finished products of alloy steel, other than stainless steel or high-speed steel, that are of a high-nickel alloy composition. These products are characterized by their significant nickel content, which imparts specific properties such as enhanced corrosion resistance, toughness, and high-temperature strength. Examples include blooms, billets, and slabs made from alloys where nickel is a primary alloying element, intended for further processing into various finished steel articles.

While the broader category encompasses "Other alloy steel in ingots or other primary forms; semi-finished products of other alloy steel," this specific subdivision narrows the focus to those made from "high-nickel alloy steel." This distinction is crucial for accurate classification, as it isolates materials whose properties are specifically attributable to the high nickel content, differentiating them from other types of alloy steels that may have different alloying elements or proportions.

As this is a leaf node within the HTS structure, there are no further subcategories under 7224.90.00.05. Classification at this level is final for goods fitting the description of semi-finished high-nickel alloy steel. Therefore, the determination rests on confirming the material composition meets the criteria for a high-nickel alloy steel and that the product is in a semi-finished form such as ingots, blooms, billets, or slabs, as outlined by the preceding HTS headings.
