Overview

This HTS category, HTS Code 7304.24.40.80, specifically classifies seamless tubes and pipes of iron or steel that are of a kind used in drilling for oil or gas, are made of stainless steel, and are designated as casing. The defining characteristic of this particular sub-classification is that the casing must have an outside diameter exceeding 406.4 mm.

It is crucial to distinguish this category from its siblings, which are differentiated by their outside diameters. Categories with outside diameters less than 215.9 mm, between 215.9 mm and 285.8 mm, or exceeding 285.8 mm but not exceeding 406.4 mm, fall under separate classifications. Therefore, only stainless steel casing for oil and gas drilling with an outside diameter greater than 406.4 mm will be classified under 7304.24.40.80.

As this is a leaf node within the HTS structure, there are no further subcategories. Classification under this code is determined solely by the material (stainless steel), the intended use (oil and gas drilling casing), the seamless nature of the product, and, most importantly, the specified outside diameter exceeding 406.4 mm.
