Overview
This category, HTS 7306.30.50.31, specifically classifies welded tubes, pipes, and hollow profiles of iron or non-alloy steel that have a circular cross-section, a wall thickness of 1.65 mm or more, and an outside diameter not exceeding 50.8 mm. These items are finished products, typically used in various industrial applications where structural integrity and specific dimensional tolerances are critical. Examples include certain types of conduit, mechanical tubing, and structural components where the specified diameter is a key defining characteristic.
This specific classification is distinguished from its sibling, 7306.30.50.33, by its strict outer diameter limitation. While both are welded, circular, and galvanized iron or non-alloy steel tubes with a wall thickness of 1.65 mm or more, 7306.30.50.31 covers those with an outside diameter *not exceeding* 50.8 mm. In contrast, 7306.30.50.33 encompasses those with an outside diameter that *exceeds* 50.8 mm but does not go beyond 114.3 mm. This precise dimensional threshold is the primary differentiator for classification purposes.
As this HTS code represents a leaf node, there are no further subcategories. Classification therefore hinges entirely on meeting all the preceding criteria: being a welded tube, pipe, or hollow profile of iron or steel, of circular cross-section, with a wall thickness of 1.65 mm or more, and possessing an outside diameter of 50.8 mm or less. The "Galvanized" designation is also crucial, indicating a protective zinc coating has been applied.
