Overview

This HTS classification, 7304.19.10.20, pertains to seamless pipes and tubes made of iron or nonalloy steel, specifically those designated for use in oil or gas pipelines. The defining characteristic for this subcategory is their outside diameter, which must not exceed 114.3 millimeters. These are commonly referred to as "line pipe" due to their intended application in transporting hydrocarbons.

This category is differentiated from its siblings based on precise diameter ranges. For instance, sibling category 7304.19.10.30 covers line pipe with an outside diameter exceeding 114.3 mm but less than 215.9 mm. Further distinctions exist for larger diameter pipes, with other sibling categories addressing diameters of 215.9 mm or more up to 406.4 mm, and those exceeding 406.4 mm. Therefore, accurate measurement of the outside diameter is critical for correct classification within this group of line pipe.

As this is a leaf node within the HTS classification system, there are no further subdivisions under 7304.19.10.20. Classification at this level is complete based on the material (iron or nonalloy steel), intended use (line pipe for oil or gas pipelines), seamless construction, and the specified outside diameter not exceeding 114.3 mm. Importers and exporters should ensure that all these criteria are met for goods falling under this code.
