7214.99.00.21 - With a diameter of 76 mm or more but not exceeding 152 mm

This HTS classification covers other bars and rods of iron or nonalloy steel that have undergone primary working processes such as forging, hot-rolling, hot-drawing, or hot-extrusion, and have subsequently been twisted. Specifically, this subcategory pertains to round bars and rods with a carbon content by weight of less than 0.25 percent. The defining characteristic for inclusion here is the diameter of the bar or rod, which must be 76 mm or greater but not exceed 152 mm.

This category is distinguished from its siblings based on precise diameter ranges. Bars and rods with a diameter less than 76 mm are classified under 7214.99.00.16, while those exceeding 152 mm fall under 7214.99.00.26. This level of specificity ensures accurate classification based solely on the physical dimension of the circular cross-section, assuming all other conditions for the parent category are met.

As this is a leaf node within the HTS, there are no further subcategories. Classification within 7214.99.00.21 is complete once the material (iron or nonalloy steel), working processes (forged, hot-rolled, hot-drawn, or hot-extruded, and potentially twisted), the form (round), carbon content (less than 0.25 percent), and diameter (76 mm or more but not exceeding 152 mm) are confirmed. Examples of goods that would fall here include specific sizes of rebar or structural components where the diameter falls within this defined range.
