7217.20.45.50 - Containing by weight 0.25 percent or more but less than 0.6 percent of carbon

This HTS classification, 7217.20.45.50, specifically covers iron or nonalloy steel wire that has been plated or coated with zinc. The defining characteristic of this subcategory is its carbon content, which must be 0.25 percent or more but less than 0.6 percent by weight. The wire must also have a diameter ranging from 1.0 mm to, but not including, 1.5 mm. This specific carbon content range, combined with the physical dimensions and zinc coating, distinguishes these products for customs purposes.

This category is differentiated from its sibling nodes by its precise carbon content. Category 7217.20.45.40 includes wire with a carbon content of less than 0.25 percent, while 7217.20.45.60 covers wire with 0.6 percent or more of carbon. Therefore, the key differentiator here is the intermediate range of carbon content, defining a specific metallurgical composition for the zinc-coated iron or nonalloy steel wire of the specified diameter.

As this is a leaf node in the HTS structure, there are no further subcategories branching from 7217.20.45.50. This means that any iron or nonalloy steel wire meeting all the preceding criteria – being plated or coated with zinc, having a round cross-section, a diameter between 1.0 mm and 1.5 mm, and containing by weight 0.25 percent or more but less than 0.6 percent of carbon – will be classified directly under this code. Examples would include specific types of galvanized wire used in fencing, general manufacturing, or construction that fall within these precise specifications.
