7217.20.45.80 - Containing by weight 0.6 percent or more of carbon

This HTS category, 7217.20.45.80, classifies wire made from iron or nonalloy steel that has been plated or coated with zinc. Specifically, it covers round wire with a diameter of 1.5 millimeters or more, which contains by weight 0.6 percent or more of carbon. This high carbon content is a critical determinant for classification within this subcategory.

This category is distinguished from its sibling, 7217.20.45.70, by the specific carbon content threshold. While both are zinc-plated, round iron or nonalloy steel wires with a diameter of 1.5 mm or more, this category is for wires with a higher carbon concentration (0.6% or more), whereas the sibling is for those with a lesser concentration (0.25% but less than 0.6%). This differentiation is crucial for accurately applying tariff rates based on the metallurgical properties of the steel wire.

As this is a leaf node within the HTS structure, there are no further subdivisions. Classification under this code is final, requiring careful verification of the wire's diameter, plating, form (round), and, most importantly, its carbon content to ensure accurate customs declaration. Examples of goods that would fall here include certain types of galvanized steel wire used in construction or manufacturing where higher tensile strength due to increased carbon content is required.
