7213.99.00.30 - With a diameter of 14 mm or more but less than 19 mm

This HTS category, 7213.99.00.30, specifically classifies hot-rolled bars and rods of iron or non-alloy steel, presented in irregularly wound coils, that have a circular cross-section and a diameter ranging from 14 mm up to, but not including, 19 mm. These are typically semi-finished or unfinished products used as feedstock for further manufacturing processes, such as wire drawing, cold forming, or machining into more complex components.

This specific classification distinguishes itself from its sibling category, 7213.99.00.60, by the precise diameter of the bars and rods. While both fall under the broader "other" classifications for hot-rolled coils of iron or non-alloy steel with circular cross-sections, 7213.99.00.30 is designated for those with diameters of 14 mm or more but less than 19 mm, whereas the sibling covers diameters of 19 mm and above. This diameter-based distinction is crucial for accurate customs declaration and duty assessment.

As this node represents a leaf in the HTS classification tree, there are no further subcategories. Therefore, classification within 7213.99.00.30 is determined solely by the material (iron or non-alloy steel), the form (hot-rolled, irregularly wound coils), the cross-section (circular), and the specified diameter range (14 mm to less than 19 mm). Any deviation in these characteristics would necessitate classification under a different HTS code.
