Overview
This HTS subcategory, 7304.29.41.40, specifically classifies seamless pipes and tubes of iron or steel that are of a kind used for drilling for oil or gas, fall under the "Other casing" and "Of other alloy steel" categories, and possess an outside diameter between 215.9 mm and 285.8 mm. The defining characteristic for this particular classification is that these articles must have a wall thickness of 12.7 mm or greater.
This contrasts with its sibling category, 7304.29.41.30, which covers items meeting all the same criteria except for having a wall thickness less than 12.7 mm. Therefore, the distinction hinges solely on this precise measurement of wall thickness.
As this is a leaf node in the HTS structure, there are no further subdivisions under this code. Classification is complete once all preceding criteria, including the specific outside diameter range and the wall thickness of 12.7 mm or more, are met. This means goods entering this classification are typically robust casing pipes designed for demanding oil and gas extraction environments, distinguished by their substantial wall thickness within a defined diameter.
