Overview
This HTS category, 7305.11.50.00, specifically classifies longitudinally submerged arc welded tubes and pipes of iron or steel that have a circular cross-section with an external diameter exceeding 406.4 mm, and are intended for use in oil or gas pipelines. The defining characteristic of this subcategory is that the material composition must be of alloy steel.
Distinguishing this category from its sibling, 7305.11.10, is crucial. While both relate to longitudinally submerged arc welded line pipe for oil and gas, 7305.11.10 covers such pipes made of iron or nonalloy steel. Therefore, the key differentiator for 7305.11.50.00 is the presence of alloying elements in the steel, which imparts specific metallurgical properties often required for demanding oil and gas applications.
As this is a leaf node within the HTS, there are no further subcategories. Classification at this level is definitive, based on the specified weld type (longitudinally submerged arc welded), intended use (oil or gas pipelines), diameter (exceeding 406.4 mm), and the material composition (alloy steel). Examples of goods falling under this code would include large-diameter, high-strength alloy steel pipes used for transporting crude oil or natural gas, where specific resistance to corrosion, pressure, or temperature fluctuations is a primary requirement.
