7217.30.45.20 - Containing by weight 0.25 percent or more but less than 0.6 percent or carbon

This HTS classification, 7217.30.45.20, specifically covers round wire of iron or nonalloy steel that has been plated or coated with other base metals. The defining characteristic of wire in this category is its carbon content, which must be by weight 0.25 percent or more but less than 0.6 percent. The wire's diameter must also be less than 1.0 mm. This combination of properties delineates its precise place within the broader classification of plated or coated iron and steel wire.

Distinguishing this category from its siblings is crucial for accurate classification. HTS code 7217.30.45.11 covers wire with a lower carbon content (less than 0.25 percent), while 7217.30.45.30 includes wire with a higher carbon content (0.6 percent or more). Therefore, wire classified under 7217.30.45.20 falls into the mid-range for carbon content, differentiating it from both lower and higher carbon steel wires under similar plating and diameter specifications.

As a leaf node, this classification does not have further subdivisions. The specific criteria of containing by weight 0.25 percent or more but less than 0.6 percent of carbon, when combined with the other stated attributes (round wire, plated or coated with other base metals, and a diameter of less than 1.0 mm), uniquely identifies the goods for customs purposes. Importers and exporters must ensure all these conditions are met to correctly apply this HTS code.
