7225.40.30.05 - Of high-nickel alloy steel

This HTS category, 7225.40.30.05, specifically classifies flat-rolled products of other alloy steel that have been hot-rolled, are not in coils, and have a thickness of 4.75 mm or more. The defining characteristic of this subcategory is that the material is composed of high-nickel alloy steel. This means the steel contains a significant percentage of nickel, which imparts specific properties such as enhanced corrosion resistance, strength at high temperatures, or non-magnetic characteristics, depending on the exact alloy composition.

This classification is distinct from its sibling, 7225.40.30.50, which also falls under "Other" at this level but does not specify the high-nickel alloy composition. While both are hot-rolled, not in coils, and at least 4.75 mm thick, the crucial differentiator here is the presence of high-nickel alloy in the steel's composition. This specificity is vital for determining applicable duties, trade statistics, and potential regulatory requirements.

As a leaf node within the HTS, 7225.40.30.05 does not have further subcategories. Therefore, classification into this code relies solely on meeting all the preceding criteria: being a flat-rolled product of other alloy steel, over 600 mm wide, hot-rolled, not in coils, at least 4.75 mm thick, and specifically being of the high-nickel alloy steel type. Examples might include certain grades of stainless steel or specialized structural steels where nickel is a primary alloying element beyond the standard alloying elements typically found in "other alloy steel."
