Overview
This HTS category, 7304.39.00.40, specifically covers seamless tubes and pipes made of iron or non-alloy steel, which are of circular cross-section and fall under the "other" sub-classifications within the broader category of "other" seamless pipes. The defining characteristic for inclusion in this specific code is the wall thickness: it must be 12.7 mm or greater, but strictly less than 19 mm. These are typically robust pipes designed for applications requiring significant structural integrity and pressure resistance, beyond what thinner-walled pipes can provide.
To differentiate this category from its siblings, the primary distinction lies in wall thickness. Category 7304.39.00.36 covers similar seamless steel pipes but with a wall thickness *less than* 12.7 mm. Conversely, category 7304.39.00.44 encompasses pipes with a wall thickness of *19 mm or more*. Therefore, this classification acts as a precise middle ground, capturing seamless steel pipes with a specific, substantial, but not the most extreme, wall thickness.
As this HTS code represents a leaf node, there are no further subcategories within this specific classification. This means that once a seamless iron or steel tube or pipe meets all the preceding criteria (seamless, circular cross-section, of iron or non-alloy steel, and within the specified outside diameter range), its classification is definitively determined by its wall thickness falling between 12.7 mm and 19 mm. Examples of such goods could include heavy-duty industrial piping, structural components, or specialized conduits where precise wall thickness is critical for performance and regulatory compliance.
