7225.30.30.05 - Of high-nickel alloy steel

This HTS category, 7225.30.30.05, specifically classifies flat-rolled products of other alloy steel, with a width of 600 mm or more, that have been hot-rolled, are in coils, have a thickness of 4.75 mm or more, and are made of high-nickel alloy steel. The defining characteristic here is the specific alloy composition, requiring a significant content of nickel, distinguishing it from general "other alloy steel" categories.

While the preceding classification levels establish broad criteria for hot-rolled alloy steel coils, this subcategory focuses on a particular material composition. Its direct sibling, 7225.30.30.50, also falls under "Other" but lacks the specific "high-nickel alloy steel" designation, implying it covers other alloy steels not meeting the high-nickel content requirement.

As this is a leaf node, there are no further subcategories to introduce. Classification within this specific code hinges entirely on the steel meeting the criteria of being an "other alloy steel" and possessing a high nickel content, in addition to the dimensions and processing methods already established by its parent nodes. This detailed specification ensures accurate tariff application for these specialized alloy steel products.
