7217.30.45.30 - Containing by weight 0.6 percent or more of carbon

This HTS category, 7217.30.45.30, classifies wire of iron or nonalloy steel that is plated or coated with other base metals, has a round cross-section, and contains by weight 0.6 percent or more of carbon. The wire's diameter is also a key characteristic, falling under the broader group of wires with a diameter of less than 1.0 mm, within the "Other" subcategory for round wires of this type.

This specific classification is distinguished from its sibling categories by its carbon content. While 7217.30.45.11 covers wire with less than 0.25 percent carbon, and 7217.30.45.20 encompasses wire with 0.25 percent or more but less than 0.6 percent carbon, this category specifically includes wire with a carbon content of 0.6 percent or greater. This distinction is crucial for accurate tariff assessment.

As a leaf node within the HTS database, this category does not have further subcategories. Therefore, the focus for classification under this code is on ensuring all preceding criteria are met: the material being iron or nonalloy steel wire, its plating or coating with other base metals, its round shape, its diameter being less than 1.0 mm, and most critically, its carbon content of 0.6 percent or more by weight.
