Overview

This HTS category, 7304.19.10.80, specifically classifies seamless tubes and pipes made of iron or non-alloy steel that are designed for use in oil or gas pipelines and possess an outside diameter exceeding 406.4 mm. These are substantial pipes intended for the conveyance of hydrocarbons under significant pressure.

This subcategory is distinguished from its siblings by its exceptionally large diameter. While other categories within 7304.19.10 cover smaller diameter line pipe, this classification applies to pipes that surpass the 406.4 mm threshold, representing the largest diameter line pipe within this specific group.

As this is a leaf node, there are no further subcategories to introduce. The classification is complete at this level based on the material (iron or non-alloy steel), application (oil or gas pipeline), seamless construction, and the critical physical characteristic of having an outside diameter exceeding 406.4 mm. Importers and exporters should carefully measure the outside diameter of their line pipe to ensure correct classification within the appropriate sibling category.
