7214.99.00.36 - 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, not further worked than forged, hot-rolled, hot-drawn or hot-extruded, but including those twisted after rolling," specifically within the "Other" subcategory of "Other" bars and rods, and further refined to "Rounds" containing 0.25 percent or more but less than 0.6 percent carbon by weight. The defining characteristic for this specific sub-classification is the physical dimension of the round bars or rods.

The primary criterion for inclusion in HTS code 7214.99.00.36 is that these round bars and rods must have a diameter that is equal to or greater than 76 mm but does not exceed 152 mm. This distinguishes them from their sibling categories. For instance, sibling 7214.99.00.31 covers similar round bars and rods with a diameter *less than* 76 mm, while sibling 7214.99.00.40 encompasses those with a diameter *exceeding* 152 mm. Therefore, this category acts as an intermediate size range for these specific iron and nonalloy steel products.

As this is a leaf node in the HTS classification system, there are no further subcategories branching from this code. Classification decisions at this level rely solely on the material composition (iron or nonalloy steel with a specific carbon content) and the precise diameter range of the round bars or rods. Importers and exporters must carefully measure and confirm the diameter to ensure correct classification.
