7217.30.45.90 - With a diameter of 1.5 mm or more

This HTS category, 7217.30.45.90, specifically classifies round wire made from iron or nonalloy steel that has been plated or coated with base metals *other than* zinc, tin, or nickel. The defining characteristic of this subcategory is that the wire has a diameter measuring 1.5 mm or more. This indicates a relatively robust gauge of wire, intended for applications where strength and durability are primary considerations.

The distinction between this category and its siblings lies solely in the physical dimension of the wire's diameter. While siblings at the same level might cover wire with diameters less than 1.0 mm, or between 1.0 mm and 1.5 mm, this specific classification is reserved for the thicker gauges, beginning at 1.5 mm and extending upwards. This granular breakdown by diameter is crucial for accurate tariff application, as different sizes of wire may have distinct end-uses and market values.

As this is a leaf node within the HTS classification system, there are no further subcategories. Therefore, the primary focus for classification under 7217.30.45.90 is the precise measurement of the wire's diameter and confirmation that it is indeed round, made of iron or nonalloy steel, and coated with a base metal other than zinc, tin, or nickel. This ensures that goods falling under this heading are correctly identified for customs purposes.
