Overview
This HTS classification, 7304.39.00.72, specifically identifies seamless tubes, pipes, and hollow profiles made of iron or nonalloy steel that have a circular cross-section. The defining characteristic for this subcategory is a wall thickness of 19 mm or more, in conjunction with an outside diameter that falls within the range of exceeding 285.8 mm but not exceeding 406.4 mm. These are typically robust, heavy-duty steel conduits designed for demanding industrial applications.
This category is distinguished from its siblings by its precise wall thickness and diameter specifications. For instance, HTS code 7304.39.00.62 covers items with a wall thickness less than 12.7 mm, while 7304.39.00.68 includes those with a wall thickness of 12.7 mm or more but less than 19 mm. Therefore, this classification is exclusively for those articles with the thickest walls within this diameter range, indicating a higher structural integrity or capability for handling extreme pressures or loads.
As this node represents a leaf in the HTS classification tree, there are no further subcategories. Classification at this level is determined solely by the combination of material (iron or nonalloy steel), construction (seamless), cross-sectional shape (circular), outside diameter, and the critical wall thickness of 19 mm or more.
