7306.69.70.60 - Other

This HTS category, 7306.69.70.60, encompasses welded tubes, pipes, and hollow profiles made from iron or steel that have a noncircular cross-section and a wall thickness of less than 4 mm, and are specifically composed of alloy steel. Alloy steel, for classification purposes, refers to iron-based metal alloys where the addition of alloying elements like manganese, chromium, nickel, or molybdenum significantly enhances its properties beyond those of ordinary carbon steel. The "Other" in the description signifies that these items do not fall into more specific subcategories within this level.

This classification distinguishes itself from its sibling, 7306.69.70.30 (Of stainless steel), by the specific metallurgical composition of the alloy steel. While stainless steel is a type of alloy steel, this category is intended for welded articles of iron or steel with a noncircular cross-section and wall thickness under 4 mm that are made of alloy steels that do not meet the specific chemical composition or performance characteristics defining stainless steel (typically characterized by a minimum chromium content of 10.5%).

As this is a leaf node, there are no further subcategories within this specific HTS code. Therefore, the classification hinges directly on the presence of alloy steel composition, a noncircular cross-section, welded construction, and a wall thickness under 4 mm. Importers should verify that the material composition meets the criteria for alloy steel, as defined by relevant metallurgical standards or customs rulings, to ensure correct classification.
