Overview
This HTS category, 7305.31.40.00, specifically covers longitudinally welded tubes and pipes of iron or nonalloy steel. These are large-diameter pipes (external diameter exceeding 406.4 mm) that are formed by joining metal along their length. The critical distinguishing feature of this subcategory is its material composition; it is exclusively for products made from iron or nonalloy steel.
It is important to distinguish this category from its sibling, 7305.31.60. While both fall under longitudinally welded tubes and pipes with circular cross-sections and diameters exceeding 406.4 mm, the sibling category is reserved for those made of alloy steel. Therefore, the presence of alloying elements beyond those typically found in iron or nonalloy steel would direct a product to the 7305.31.60 classification.
As this is a leaf node, there are no further subdivisions under 7305.31.40.00. Classification at this level is definitive for longitudinally welded pipes of iron or nonalloy steel meeting the specified diameter criteria. Examples of goods classified here would include large diameter pipelines used in infrastructure projects, such as water mains or oil and gas transport lines, where the primary material is confirmed to be iron or nonalloy steel, and the welding seam runs along the length of the pipe.
