7217.20.45.20 - Containing by weight 0.25 percent or more but less than 0.6 percent of carbon

This HTS category, 7217.20.45.20, specifically classifies wire of iron or nonalloy steel that has been plated or coated with zinc, and has a round cross-section with a diameter of less than 1.0 mm. The defining characteristic of this classification is its carbon content, which must range from 0.25 percent to less than 0.6 percent by weight. This precise carbon threshold differentiates it from other classifications of similarly sized and coated round wire.

This classification is distinguished from its sibling categories by its specific carbon percentage range. For example, sibling 7217.20.45.10 covers wire with a lower carbon content (less than 0.25%), while sibling 7217.20.45.30 encompasses wire with a higher carbon content (0.6% or more). Therefore, accurate carbon analysis is critical for correct classification within this group.

As this is a leaf node in the HTS system, there are no further subdivisions under this specific code. All goods meeting the criteria of being round, zinc-plated or coated iron or nonalloy steel wire with a diameter under 1.0 mm and containing by weight 0.25 percent or more but less than 0.6 percent of carbon will be classified here. Examples of such wire might be used in specialized manufacturing processes or as components in certain consumer goods where a moderate carbon steel wire with zinc protection is required.
