Overview
This HTS category, 7304.24.30.40, specifically classifies seamless iron or steel casing, tubing, and drill pipe of a kind used in oil and gas drilling operations. These are further characterized as being made of stainless steel, threaded or coupled, and possessing an outside diameter between 215.9 mm and 285.8 mm. The defining criterion for this subclassification is a substantial wall thickness of 12.7 mm or more.
This classification is distinguished from its sibling category, 7304.24.30.30, by this precise wall thickness specification. While both cover similar oil and gas drilling pipe with the same outside diameter range and material, the physical dimension of the pipe wall thickness is the sole differentiating factor. Goods classified under 7304.24.30.40 are therefore robust pipes designed for more demanding drilling environments requiring greater structural integrity.
As this is a leaf node within the HTS structure, there are no further subcategories. Classification ceases at this level, meaning that once the criteria of material (stainless steel), application (oil/gas drilling), connection type (threaded or coupled), outside diameter range (215.9 mm to 285.8 mm), and wall thickness (12.7 mm or more) are met, the goods fall definitively into this category.
