Overview
This HTS classification, 7306.19.51.50, specifically covers welded tubes, pipes, and hollow profiles of iron or steel that are of a kind used for oil or gas pipelines, are made of alloy steel, and have an outside diameter exceeding 114.3 mm. These are generally larger diameter pipes intended for the transmission of oil and natural gas, where the specific alloy composition and the substantial diameter are critical functional attributes.
This category is distinguished from its sibling, 7306.19.51.10, solely by the physical dimension of the outside diameter. While both are line pipe of alloy steel used for oil or gas pipelines, the .50 subcategory specifically applies to those with an outside diameter *greater than* 114.3 mm, indicating a distinction in scale and potentially application compared to the smaller diameter pipes classified under .10.
As this is a leaf node within the HTS structure, there are no further subcategories to introduce. Classification at this level is determined by the cumulative criteria established in the parent headings: being a welded tube, pipe, or hollow profile of iron or steel, specifically designed for oil or gas pipelines, constructed from alloy steel, and possessing an outside diameter exceeding 114.3 mm.
