Overview

This HTS category specifically covers seamless pipes and tubes made of iron or steel that are used as casing in the drilling of oil or gas wells. These items are further defined by their material composition, being of stainless steel. The critical distinguishing feature for classification within this sub-heading is the wall thickness of the pipe or tube.

Goods classified under 7304.24.40.50 are characterized by having a wall thickness *less than* 12.7 mm. This is in direct contrast to its sibling category, 7304.24.40.60, which covers similar casing pipes but with a wall thickness *of 12.7 mm or more*. Therefore, precise measurement of the wall thickness is paramount for accurate classification at this level.

As this is a leaf node in the HTS, there are no further subdivisions under this specific code. Classification is finalized based on the criteria of being stainless steel casing, used for oil/gas drilling, having an outside diameter between 285.8 mm and 406.4 mm, and most importantly, possessing a wall thickness under 12.7 mm. Any deviation in these specific physical attributes would necessitate classification under a different HTS code.
