7304.29.10.60 - Having a wall thickness of 12.7 mm or more

This HTS category, 7304.29.10.60, specifically classifies seamless tubes and pipes made of iron or nonalloy steel that are of a kind used in drilling for oil or gas, and are threaded or coupled. The defining characteristic for this subcategory is a wall thickness of 12.7 millimeters or more. These are typically heavy-duty components designed to withstand the significant pressures and stresses encountered in oil and gas exploration and extraction operations.

This classification is distinct from its sibling category, 7304.29.10.50, which covers similar oil and gas drilling casing, tubing, and drill pipe, also threaded or coupled, but with a wall thickness less than 12.7 millimeters. The critical differentiator here is the specified minimum wall thickness, indicating a requirement for enhanced structural integrity and robustness in the application.

As this is a leaf node within the HTS structure, there are no further subcategories to detail. Therefore, classification into 7304.29.10.60 is finalized based on the material (iron or nonalloy steel), intended use (oil/gas drilling), construction (seamless, threaded or coupled), and the specific physical attribute of having a wall thickness of 12.7 mm or more, with an outside diameter exceeding 285.8 mm but not exceeding 406.4 mm.
