7304.39.00.62 - Having a wall thickness less than 12.7 mm

This HTS category, 7304.39.00.62, specifically covers seamless tubes, pipes, and hollow profiles made from iron or non-alloy steel that have a circular cross-section. The defining characteristic for this classification is their wall thickness, which must be less than 12.7 mm. Furthermore, these articles must have an outside diameter that exceeds 285.8 mm but does not exceed 406.4 mm. This detailed dimension establishes a precise scope for products that might otherwise be broadly categorized.

To differentiate this category from its siblings, consider the wall thickness. HTS code 7304.39.00.68 is for similar seamless pipes with a wall thickness of 12.7 mm or more, but less than 19 mm. The sibling 7304.39.00.72 pertains to even thicker walls, those measuring 19 mm or more. Therefore, the key distinction lies in the precise measurement of the material's thickness, ensuring accurate tariff application based on the physical construction of the pipe or tube.

As this is a leaf node within the HTS, there are no further subcategories to explore. The classification is definitive based on the combination of material (iron or non-alloy steel), construction (seamless), cross-section (circular), outside diameter range, and critically, the wall thickness being less than 12.7 mm. This precise definition avoids ambiguity for customs purposes, ensuring that goods falling within these specific parameters are consistently classified.
