Overview
This HTS category, 7304.24.30.45, specifically classifies seamless casing pipes made of iron or steel, intended for use in oil and gas drilling operations. The defining characteristic for this classification is the pipe's external diameter, which must fall within a precise range: greater than 285.8 mm and not exceeding 406.4 mm. These pipes are often threaded or coupled to facilitate secure connections in downhole applications.
To differentiate this category from its siblings, the critical distinguishing factor is the outside diameter. Unlike sibling categories that cover casing with smaller diameters (less than 215.9 mm or between 215.9 mm and 285.8 mm), or those with larger diameters (exceeding 406.4 mm), this node isolates a specific mid-range diameter for casing. This precise measurement is crucial for ensuring proper fit and function within various drilling assemblies and wellbore configurations.
As this is a leaf node within the HTS classification system, there are no further subcategories. Therefore, the classification relies entirely on the specified material (iron or steel), application (oil and gas drilling casing), joining method (threaded or coupled), and the precise outer diameter range. Importers and exporters must ensure their goods meet all these criteria to be correctly classified under 7304.24.30.45.
