Overview
This HTS classification, 7304.29.41.20, specifically covers seamless pipes and tubes of iron or steel that are used as casing in drilling operations for oil or gas. These articles are characterized by being made of "other alloy steel" and are further distinguished by their physical dimensions. The critical defining factor for this subcategory is that the wall thickness of the casing must be 12.7 millimeters or more.
This category is differentiated from its sibling, 7304.29.41.10, by this precise wall thickness measurement. While both describe casing used in oil and gas drilling and are made from other alloy steel with an outside diameter less than 215.9 mm, the distinction lies solely in the wall thickness. 7304.29.41.10 pertains to casing with a wall thickness *less than* 12.7 mm, whereas this category encompasses casing with a wall thickness *equal to or greater than* 12.7 mm.
As a leaf node within the HTS structure, there are no further subcategories branching from 7304.29.41.20. Therefore, the classification is complete at this level, relying on the specified material (other alloy steel), intended use (oil and gas casing), outside diameter (less than 215.9 mm), and critically, the wall thickness of 12.7 mm or more to accurately identify these specialized seamless steel tubes.
