Overview
This HTS classification, 7304.29.31.40, specifically identifies seamless pipes and tubes made from iron or steel, falling under the broader category of casing, tubing, and drill pipe used in oil and gas drilling. The defining characteristic for this particular subcategory is its significant wall thickness, specified as being 12.7 mm or greater. These are robust tubular products designed to withstand the high pressures and demanding conditions encountered in exploration and extraction operations.
This category is distinguished from its sibling, 7304.29.31.30, by the precise measurement of wall thickness. While both are classified as casing for oil and gas drilling, and share the same diameter range, this code is exclusively for items with a wall thickness of 12.7 mm or more, indicating a requirement for enhanced structural integrity compared to the thinner-walled sibling. This distinction is crucial for import and export declarations, ensuring accurate duty assessment and regulatory compliance.
As a leaf node in the HTS classification system, 7304.29.31.40 does not have further subcategories. Therefore, the classification is finalized at this level, based on the material (alloy steel), the type of product (casing), its intended use (oil and gas drilling), its method of connection (threaded or coupled), its outside diameter range, and its wall thickness of 12.7 mm or more. This level of specificity ensures that only items precisely meeting all these criteria are assigned this HTS code.
