7217.20.45.60 - Containing by weight 0.6 percent or more of carbon

This HTS category, 7217.20.45.60, specifically classifies iron or nonalloy steel wire that has been plated or coated with zinc, is round in cross-section, and has a diameter ranging from 1.0 mm to less than 1.5 mm. The defining characteristic for this particular subclassification is its carbon content, which must be 0.6 percent or more by weight. This ensures precise segregation of steel wires based on their metallurgical composition and physical attributes.

This classification distinguishes itself from its sibling categories based on precise carbon percentage ranges. While 7217.20.45.40 covers wire with less than 0.25 percent carbon and 7217.20.45.50 applies to wire with 0.25 percent or more but less than 0.6 percent carbon, this category exclusively applies to wires meeting or exceeding the 0.6 percent carbon threshold. All other criteria, such as being zinc-plated, round, and within the specified diameter range, must also be met.

As this is a leaf node, there are no further subcategories. Therefore, the classification is complete at this level, encompassing all qualifying round, zinc-plated iron or nonalloy steel wire with a diameter between 1.0 mm and 1.5 mm that contains 0.6 percent or more carbon by weight. Examples of such wire might include certain types of industrial fencing wire, binding wire used in construction, or components for machinery where higher carbon content is required for strength and durability.
