7217.20.45.10 - Containing by weight less than 0.25 percent of carbon

This HTS category, 7217.20.45.10, specifically classifies round wire made from iron or nonalloy steel that has been plated or coated with zinc. The defining characteristic of this classification is its low carbon content, containing less than 0.25 percent carbon by weight. This chemical composition is a critical factor in distinguishing it from other categories within the "Other" diameter subcategory.

The distinction between this category and its siblings lies solely in the carbon content of the iron or nonalloy steel. Category 7217.20.45.20 covers wire with a carbon content between 0.25 percent and 0.6 percent, while 7217.20.45.30 encompasses wire with 0.6 percent or more carbon. Therefore, the precise analysis of the steel's carbon composition is paramount for accurate classification under these sibling codes.

As this is a leaf node, there are no further subdivisions within this specific classification. Classification is finalized once the criteria of being round wire, plated or coated with zinc, having a diameter less than 1.0 mm, and containing less than 0.25 percent carbon by weight are met. Examples of goods that would fall here include certain types of low-carbon galvanized steel wire used in general manufacturing, crafts, or as fasteners where high tensile strength due to carbon content is not required.
