Overview

This HTS subcategory, 7306.30.50.85, specifically covers welded tubes, pipes, and hollow profiles of iron or non-alloy steel that are of circular cross-section, have a wall thickness of 1.65 mm or more, and are galvanized. The "Galvanized" descriptor is a key characteristic, indicating the application of a protective zinc coating to enhance corrosion resistance. These are generally considered finished or semi-finished articles intended for a variety of industrial and structural applications where durability against rust and the elements is paramount.

The distinction between this subcategory and its sibling, 7306.30.50.90 ("Other"), lies in the explicit mention of galvanization. While the sibling category also falls under welded, circular, iron or non-alloy steel tubes with a wall thickness of 1.65 mm or more and an outside diameter between 114.3 mm and 406.4 mm, it does not specify a protective coating like galvanization. Therefore, 7306.30.50.85 is reserved for those products that have undergone the galvanizing process, differentiating them from similarly dimensioned but uncoated or differently treated products.

As this is a leaf node within the HTS, there are no further subdivisions under 7306.30.50.85. Classification at this level is definitive and based on the precise specifications outlined: welded, circular cross-section, iron or non-alloy steel, wall thickness of 1.65 mm or more, galvanized, and with an outside diameter exceeding 114.3 mm but not exceeding 406.4 mm. Importers and exporters must ensure that their merchandise precisely matches all these criteria to be correctly classified under this specific code.
