7304.59.80.65 - Having a wall thickness of 12.7 mm or more but less than 19 mm

This HTS category, 7304.59.80.65, specifically classifies seamless tubes, pipes, and hollow profiles made of iron or steel, belonging to the category of "other alloy steel" with a circular cross-section. The defining characteristic for inclusion in this subcategory is a wall thickness that is greater than or equal to 12.7 mm, but strictly less than 19 mm. These articles must also possess an outside diameter ranging from more than 285.8 mm up to and including 406.4 mm.

This classification distinguishes itself from its siblings based on precise wall thickness. Specifically, it differs from HTS 7304.59.80.60, which covers similar alloy steel pipes with a wall thickness less than 12.7 mm. It also differs from HTS 7304.59.80.70, which includes articles with a wall thickness of 19 mm or more. The combination of the specified outside diameter range and the precise wall thickness range is crucial for accurate classification within this node.

As this is a leaf node within the HTS structure, there are no further subcategories that subdivide these goods. Therefore, classification into 7304.59.80.65 is definitive once the material, cross-sectional shape, seamless construction, alloy steel nature, outside diameter, and wall thickness criteria outlined in the description are met. Importers and exporters should carefully verify these physical parameters to ensure correct duty assessment and compliance.
