7304.59.80.50 - Having a wall thickness of 12.7 mm or more but less than 19 mm

This HTS category, 7304.59.80.50, specifically covers seamless tubes and pipes of iron or steel, made from other alloy steel, with a circular cross-section. The defining characteristic for this classification is the wall thickness, which must be 12.7 mm or more but strictly less than 19 mm. These tubes and pipes also fall within the broader group defined by an outside diameter of 190.5 mm or more, but not exceeding 285.8 mm.

To distinguish this category from its siblings, consider the precise wall thickness. Category 7304.59.80.45 applies to tubes with a wall thickness less than 12.7 mm, while category 7304.59.80.55 is for those with a wall thickness of 19 mm or more. Therefore, this specific classification is the intermediate point for seamless alloy steel tubes and pipes with an outside diameter between 190.5 mm and 285.8 mm, and a wall thickness falling within the specified range of 12.7 mm to just under 19 mm.

As this is a leaf node within the HTS, there are no further subcategories. Classification under 7304.59.80.50 is determined solely by the material (other alloy steel), construction (seamless), cross-section (circular), outside diameter range, and the specific wall thickness defined. This ensures precise identification for customs purposes, differentiating these products from others with similar but not identical physical specifications.
