Overview

This HTS category, 7304.24.30.80, specifically covers threaded or coupled casing pipes made of stainless steel, designed for use in drilling for oil or gas, where the outside diameter of the pipe exceeds 406.4 mm. These are robust, specialized tubular products engineered to withstand the pressures and environmental conditions encountered in oil and gas extraction operations.

The defining characteristic of this subcategory is its large outside diameter, exceeding 406.4 mm. This distinguishes it from sibling categories that cover similar casing pipes but with smaller outside diameters, such as those less than 215.9 mm, those between 215.9 mm and 285.8 mm, and those exceeding 285.8 mm but not exceeding 406.4 mm. The specified diameter is a critical factor in determining the pipe's suitability for specific drilling depths and geological formations.

As a leaf node within the HTS structure, this category does not have further subcategories. Therefore, classification within 7304.24.30.80 is final, based on the material being stainless steel, the intended use in oil and gas drilling, the threaded or coupled nature, and the precise outside diameter exceeding 406.4 mm. Importers and exporters should ensure all these criteria are met for accurate customs declaration.
