Overview
This HTS category, 7304.29.41.50, specifically classifies seamless pipes and tubes made from iron or steel that are intended for use in drilling for oil or gas. The items within this classification are categorized as "casing" and are made of "other alloy steel" as opposed to stainless steel or high-speed steel. Crucially, these articles must possess a wall thickness strictly less than 12.7 mm to fall under this specific subheading.
This subheading is distinguished from its sibling category, 7304.29.41.60, by the precise measurement of wall thickness. While both cover similar types of alloy steel casing used in oil and gas drilling, 7304.29.41.50 applies only to those with a wall thickness below 12.7 mm, whereas 7304.29.41.60 is for articles with a wall thickness of 12.7 mm or greater. Both categories share the requirement of having an outside diameter exceeding 285.8 mm but not exceeding 406.4 mm, and are made of the same types of alloy steel for the specified drilling applications.
As this is a leaf node within the HTS, there are no further subdivisions. Therefore, classification under 7304.29.41.50 is determined by meeting all the preceding criteria: being a seamless iron or steel pipe or tube used in oil or gas drilling, identified as casing, made of other alloy steel, having an outside diameter between 285.8 mm and 406.4 mm inclusive, and most importantly, possessing a wall thickness less than 12.7 mm.
