7214.99.00.45 - Containing by weight 0.6 percent or more of carbon

This HTS category, 7214.99.00.45, specifically classifies other bars and rods of iron or nonalloy steel that have undergone forging, hot-rolling, hot-drawing, or hot-extrusion, and have been twisted after rolling. The defining characteristic for inclusion in this subcategory is a carbon content by weight of 0.6 percent or more. These are typically solid, elongated shapes with a circular cross-section, intended for various industrial applications where higher carbon content is required for strength, hardness, or other specific material properties.

It is crucial to distinguish this category from its siblings based on precise carbon content. Categories classified as "Containing by weight less than 0.25 percent of carbon" and "Containing by weight 0.25 percent or more but less than 0.6 percent of carbon" represent iron and nonalloy steel bars and rods with lower carbon compositions, which will exhibit different metallurgical characteristics and intended uses compared to those in this 0.6 percent or more carbon group.

As this HTS code represents a leaf node, there are no further subcategories for this specific classification. Therefore, the classification decision rests solely on fulfilling the criteria of being an "other" bar or rod of iron or nonalloy steel, not further worked than forged, hot-rolled, hot-drawn or hot-extruded, including those twisted after rolling, and importantly, containing by weight 0.6 percent or more of carbon. Examples within this category could include certain types of reinforcing bars, structural components, or industrial stock material requiring elevated carbon levels for their performance requirements.
