7217.30.30.00 - With a diameter of 1.5 mm or more and containing by weight less than 0.25 percent of carbon

This HTS category specifically covers wire of iron or nonalloy steel that has been plated or coated with base metals other than zinc or tin. It further refines classification by requiring the wire to have a diameter of 1.5 mm or greater and to contain by weight less than 0.25 percent of carbon. This focus on specific metallurgical and dimensional properties ensures precise identification of these plated or coated steel wires.

Distinguishing this category from its sibling, 7217.30.45, is crucial. While both are plated or coated with other base metals, this specific subcategory narrows the scope to wires with a diameter of 1.5 mm or more and a low carbon content. The sibling category "Other" would encompass plated or coated wire that does not meet these precise diameter and carbon content requirements, or potentially wires plated or coated with materials not falling under specific, more granular classifications.

As this is a leaf node, there are no further subcategories. Classification under 7217.30.30.00 is definitive once the criteria of wire diameter (1.5 mm or more), low carbon content (less than 0.25%), and plating/coating with a base metal (other than zinc or tin) are met. This classification would apply to various industrial and construction wires where specific corrosion resistance or surface properties are imparted by the non-zinc/tin metallic coating.
