Overview
This HTS classification pertains to seamless pipes and tubes made from iron or nonalloy steel, specifically casing used in the exploration and extraction of oil and natural gas. These particular items are distinguished by their substantial wall thickness, measuring 12.7 millimeters or greater. This robust construction is designed to withstand the significant pressures and stresses encountered in deep well drilling operations.
The critical differentiator for this subcategory is the minimum wall thickness of 12.7 mm. Its sibling category, HTS 7304.29.20.10, covers comparable casing but with a wall thickness *less* than 12.7 mm. Therefore, the choice between these two classifications hinges solely on the precise measurement of the pipe's wall.
As this classification represents a leaf node in the HTS structure, there are no further subcategories. Classification under this code is final and determined by the product meeting all preceding criteria, including being casing for oil and gas drilling, made of iron or nonalloy steel, having an outside diameter less than 215.9 mm, and importantly, possessing a wall thickness of 12.7 mm or more.
