7306.50.50.30 - Other, cold-drawn or cold-rolled (cold- reduced) 🖩

This HTS classification covers welded tubes, pipes, and hollow profiles of iron or steel that are not of circular cross-section and are made from other alloy steel. The "other" designation signifies that these products do not fall into the specifically enumerated categories within the broader classification of welded, circular cross-section alloy steel tubes. The key differentiating factor for inclusion here is their construction method (welded), material composition (other alloy steel), and cross-sectional shape (non-circular).

This category is distinguished from its sibling, 7306.50.50.10, which specifically covers welded alloy steel tubes of circular cross-section suitable for use in various heat exchange and boiler applications. Therefore, while both are welded alloy steel tubes, this category is for those with non-circular cross-sections that do not meet the specific functional criteria of the sibling entry. It also differentiates from other potential entries that might cover seamless tubes or tubes made from different base metals or basic carbon steel.

As this is a leaf node in the HTS database, there are no further subcategories. Classification within this specific code depends on the confirmation that the item is indeed welded, made of alloy steel (other than common grades specified elsewhere), has a non-circular cross-section, and meets the preceding criteria of having a wall thickness of 1.65 mm or more. Examples could include welded square, rectangular, or oval tubes used in construction, machinery, or structural applications where a non-circular profile is required.
