7217.90.50.60 - Containing by weight 0.25 percent or more but less than 0.6 percent of carbon

This HTS category, 7217.90.50.60, specifically classifies wire of iron or nonalloy steel that contains by weight 0.25 percent or more but less than 0.6 percent of carbon. This carbon content range is a critical defining characteristic for products falling under this code. These are typically considered "medium carbon" steels.

This classification is distinguished from its siblings by its precise carbon content. Category 7217.90.50.30 covers similar wire but with a lower carbon content (less than 0.25 percent), often referred to as low carbon steel wire. Conversely, 7217.90.50.90 encompasses wire with a higher carbon content (0.6 percent or more), characteristic of high carbon steel wire, which is generally harder and more brittle.

As this is a leaf node within the HTS, there are no further subdivisions. Therefore, the classification hinges entirely on the accurate determination of the carbon content within the specified range. Examples of wire that would fall into this category include certain types of construction wire, some industrial fasteners, and components for agricultural equipment where a balance of strength and ductility is required. Importers and exporters must rely on laboratory analysis of the steel composition to ensure correct classification.
