7214.91.00.16 - With a maximum cross section less than 152 mm

This HTS classification, 7214.91.00.16, specifically covers other bars and rods of iron or nonalloy steel that have undergone processes like forging, hot-rolling, hot-drawing, or hot-extrusion, and have subsequently been twisted. Crucially, these products are distinguished by having a maximum cross-section measuring less than 152 millimeters. They fall under the broader category of bars and rods that are not further worked beyond these initial forming processes.

The defining characteristic of this category is its specific dimensional limitation for the cross-section. It is distinct from its sibling category, 7214.91.00.20, which covers similar bars and rods but with a maximum cross-section of 152 millimeters or more. This distinction is critical for accurate customs declaration, as it relies solely on the physical measurement of the bar or rod's widest dimension.

As this is a leaf node within the HTS structure, there are no further subcategories to introduce. Therefore, the focus remains on the precise definition of the product as outlined: bars and rods of iron or nonalloy steel, other than square, containing less than 0.25 percent carbon by weight, not further worked than forged, hot-rolled, hot-drawn or hot-extruded, including those twisted after rolling, and having a maximum cross-section of less than 152 mm. Examples of such goods might include specialized reinforcing bars or structural components with a specific, relatively small cross-sectional profile.
