7225.99.00.10 - Of high-nickel alloy steel

This HTS classification, 7225.99.00.10, specifically identifies flat-rolled products of other alloy steel, exceeding 600 mm in width, which are made from high-nickel alloy steel and do not fall under any more specific subheading. The defining characteristic here is the composition of the steel, which must contain a significant proportion of nickel, contributing to specific properties like enhanced corrosion resistance or strength at high temperatures. These products are typically used in demanding applications where standard alloy steels would be insufficient.

This category is distinguished from its sibling, 7225.99.00.90, which covers "Other" flat-rolled products of other alloy steel (of a width of 600 mm or more). While both fall under the broader "Other" subheadings for flat-rolled products of other alloy steel, 7225.99.00.10 is precisely for those identified as being of a "high-nickel alloy steel" composition. If a product is an alloy steel, is flat-rolled, has a width of 600 mm or more, but is not of a high-nickel alloy steel, it would be classified under the sibling category.

As this is a leaf node within the HTS structure, there are no further subcategories. Therefore, the focus for classification within this heading is on accurately identifying the material composition as high-nickel alloy steel and confirming the physical characteristics of being flat-rolled with a width of 600 mm or more, ensuring it does not qualify for a more specific HTS code elsewhere.
