7228.50.50.05 - Of high-nickel alloy steel

This HTS category, 7228.50.50.05, specifically classifies other bars and rods of alloy steel that are further processed by cold-forming or cold-finishing. These products are characterized by their composition of alloy steel and the fact that they have undergone significant mechanical deformation or surface treatment after initial hot rolling, resulting in enhanced dimensional accuracy, surface finish, or mechanical properties. The "high-nickel alloy steel" designation indicates a specific type of alloy steel with a significant nickel content, imparting unique characteristics such as increased corrosion resistance or high-temperature strength.

As a sub-category under "Other" bars and rods not further worked than cold-formed or cold-finished, this classification is distinct from categories that might cover bars and rods of non-alloy steel or those of alloy steel that have undergone different types of finishing processes. The "high-nickel alloy steel" aspect further refines the classification beyond general "other alloy steel" categories.

Since this is a leaf node, there are no further subcategories. Therefore, classification under 7228.50.50.05 relies on confirming that the bar or rod is indeed made of an alloy steel containing a notable proportion of nickel and has been cold-formed or cold-finished, as opposed to merely being hot-rolled or subjected to other types of working. Common examples would include precision ground or drawn bars for use in specialized machinery, aerospace components, or demanding marine applications where high nickel content is crucial for performance.
