7214.99.00.31 - With a diameter less than 76 mm

This HTS category, 7214.99.00.31, specifically classifies bars and rods of iron or non-alloy steel that have undergone basic working processes like forging, hot-rolling, hot-drawing, or hot-extrusion, and have subsequently been twisted. The defining characteristic of goods within this subcategory is their diameter, which must be less than 76 mm. These items are not further worked beyond these initial shaping and twisting processes.

This specific classification is distinguished from its sibling categories by its precise diameter limitation. Unlike 7214.99.00.36, which covers bars and rods with diameters ranging from 76 mm up to and including 152 mm, and 7214.99.00.40, which encompasses those exceeding 152 mm, this category exclusively applies to the smaller diameter range. The material composition is further narrowed by the parent category, requiring a carbon content of 0.25% or more but less than 0.6% by weight.

As this is a leaf node, there are no further subcategories to introduce. Classification at this level is therefore final and relies entirely on the specified diameter being less than 76 mm, alongside the stipulated carbon content and initial working processes detailed in the parent categories. This ensures precise identification for import and export purposes, differentiating it from other similarly processed iron and steel bars and rods with different dimensional attributes.
