7225.50.80.10 - Of high-nickel alloy steel

This HTS category, 7225.50.80.10, specifically classifies flat-rolled products of other alloy steel, exceeding 600 mm in width, that have been cold-rolled (cold-reduced) and are of a thickness less than 4.75 mm. The defining characteristic of goods within this subcategory is their composition as a "high-nickel alloy steel." This designation indicates a significant presence of nickel as an alloying element, which imparts specific properties such as enhanced corrosion resistance, high-temperature strength, or ductility, differentiating them from other types of alloy steels.

At this level of detail, the distinction from the sibling category, 7225.50.80.80 "Other," lies in the explicit identification of the material as a high-nickel alloy steel. While the sibling category would encompass other alloy steels that do not meet the specific criteria for high-nickel content, this code isolates those products with that particular metallurgical characteristic. The classification hinges on the precise chemical composition of the steel.

As this is a leaf node, there are no further subcategories. Therefore, proper classification under 7225.50.80.10 requires confirmation of both the physical attributes (flat-rolled, width >= 600 mm, cold-rolled, thickness < 4.75 mm) and the specified material composition of high-nickel alloy steel. This ensures that only products meeting all these stringent criteria are correctly categorized for customs purposes.
