7505.22 - Of nickel alloys:

This category, HTS 7505.22, specifically covers wire made from nickel alloys. It encompasses all forms of nickel alloy wire, regardless of its surface treatment or finish, as long as it is composed of nickel in alloy form.

Distinguishing this category from its sibling, 7505.21, is the material composition. While 7505.21 pertains to wire made of pure nickel (not alloyed), HTS 7505.22 is exclusively for wire where nickel is mixed with one or more other elements to create an alloy with specific properties.

Within HTS 7505.22, a further distinction is made based on the manufacturing process. Subcategory 7505.22.10.00 applies to wire that has undergone a cold-forming process, which typically involves shaping the wire at room temperature to achieve desired dimensions and mechanical properties. In contrast, 7505.22.50.00 covers nickel alloy wire that has not been cold-formed, implying it may have been produced through other methods such as hot rolling or extrusion.
