Overview
This HTS category, 7304.31.30.00, specifically classifies hollow bars of iron or steel that are of circular cross-section and have undergone cold-drawing or cold-rolling (cold-reduction) processes. These are seamless tubes and pipes, distinct from welded or formed profiles. The cold-working process imbues these products with enhanced mechanical properties, such as improved surface finish and tighter dimensional tolerances, which are key differentiating factors.
It is crucial to distinguish this classification from its sibling, 7304.31.60, which covers "Other" hollow bars of iron or non-alloy steel with a circular cross-section. While both are seamless and cold-worked, 7304.31.30.00 specifically applies to hollow bars, implying a thicker wall relative to the overall diameter and often a more robust structural or mechanical application, whereas 7304.31.60 would encompass other types of tubes and pipes that may have thinner walls or different intended uses.
As this is a leaf node in the HTS, there are no further subcategories. Therefore, classification within 7304.31.30.00 hinges on confirming that the goods are indeed seamless hollow bars of iron or non-alloy steel, possess a circular cross-section, and have been manufactured through either cold-drawing or cold-rolling. Examples of goods that would fall here include precision steel tubing used in machinery, hydraulic cylinders, or specialized structural components where the aforementioned cold-working benefits are essential.
