7217.10.80.90 - With a diameter of 1.5 mm or more

This HTS category, 7217.10.80.90, specifically classifies wire of iron or nonalloy steel that is not plated or coated, whether or not polished, and which contains by weight 0.6 percent or more of carbon. The defining characteristic of this subcategory is its physical dimension: it covers round wire with a diameter of 1.5 mm or more.

It is crucial to distinguish this category from its siblings. Category 7217.10.80.60 pertains to similar wire with a diameter of less than 1.0 mm, while 7217.10.80.75 covers wire with a diameter ranging from 1.0 mm up to, but not including, 1.5 mm. Therefore, the determining factor for classification into this specific subcategory is that the wire's diameter must meet or exceed 1.5 mm.

As this is a leaf node within the HTS structure, there are no further subcategories to introduce. Classification within 7217.10.80.90 is final, contingent upon the wire meeting all preceding criteria: being of iron or nonalloy steel, not plated or coated, round, containing 0.6% or more carbon by weight, and having a diameter of 1.5 mm or greater. Examples of goods falling under this classification could include heavier gauge steel wire used in construction, manufacturing of tools, or industrial springs where high tensile strength is required.
