7214.91.00.60 - Containing by weight 0.25 percent or more but less than 0.6 percent of carbon

This HTS category, 7214.91.00.60, specifically classifies "Other bars and rods of iron or nonalloy steel, not further worked than forged, hot-rolled, hot-drawn or hot-extruded, but including those twisted after rolling," that are of a rectangular (other than square) cross-section, and critically, contain by weight 0.25 percent or more but less than 0.6 percent of carbon. These are typically semi-finished or finished steel products used in various manufacturing applications where the specific carbon content is a key determinant of their physical properties and suitability for further processing.

This classification is distinct from its siblings based on precise carbon content. It differentiates from the category "Containing by weight less than 0.25 percent of carbon" by requiring a higher minimum carbon level. Conversely, it is also distinguished from the category "Containing by weight 0.6 percent or more of carbon" by having an upper limit on the carbon percentage. The "Other" and "Of rectangular (other than square) cross-section" designations within the hierarchy further define these bars and rods as not being of simple square cross-section and not fitting into more specifically defined categories of bars and rods under heading 7213.

As this is a leaf node within the HTS classification system, there are no further subcategories under 7214.91.00.60. Therefore, the classification is fully defined by the criteria of being a hot-worked bar or rod of iron or nonalloy steel, with a rectangular cross-section, and possessing a carbon content within the specified range of 0.25% to less than 0.6% by weight. Examples of products that would fall here include, but are not limited to, certain types of reinforcing bars, structural components, or shafts manufactured to these precise specifications.
