7306.30.50.41 - With an outside diameter not exceeding 50.8 mm

This HTS classification, 7306.30.50.41, specifically covers welded tubes and pipes of iron or non-alloy steel, which have a circular cross-section, a wall thickness of 1.65 mm or more, and are imported with a coupling attached. The defining characteristic of this category is that these coupled tubes and pipes have an outside diameter not exceeding 50.8 mm. These are typically used in fluid conveyance systems where the coupling is an integral part of the product as imported.

This category is distinguished from its sibling, 7306.30.50.43, by the outside diameter. While both are welded, circular, have a wall thickness of 1.65 mm or more, and are imported with a coupling, this classification is exclusively for those with an outside diameter of 50.8 mm or less. The sibling category encompasses those with an outside diameter exceeding 50.8 mm but not exceeding 114.3 mm.

As this is a leaf node within the HTS structure, there are no further subcategories. Classification decisions at this level hinge precisely on the combination of material (iron or non-alloy steel), construction (welded, circular), wall thickness (1.65 mm or more), presence of a coupling upon import, and the specific outside diameter range.
