7306.11.00.10 - With an outside diameter not exceeding 114.3 mm

This HTS category, 7306.11.00.10, specifically classifies welded tubes, pipes, and hollow profiles made of stainless steel that are designed for use in oil or gas pipelines and possess an outside diameter *not exceeding* 114.3 millimeters. These are typically seamless or welded tubular products manufactured from stainless steel alloys, intended for the safe and efficient transport of oil and natural gas. The material composition and construction methods ensure resistance to corrosion and high pressures, critical for pipeline applications.

It is important to distinguish this classification from its sibling category, 7306.11.00.50. The primary differentiating factor between these two closely related classifications is the *outside diameter* of the pipe. While 7306.11.00.10 applies to pipes with an outside diameter of 114.3 mm or less, 7306.11.00.50 covers those exceeding this specific measurement. This diameter threshold is a key criterion for accurate customs classification, influencing factors like handling, jointing methods, and potential applications.

As this is a leaf node within the HTS database, there are no further subcategories to introduce. The classification is definitively determined by the material (stainless steel), manufacturing method (welded), intended use (line pipe for oil or gas pipelines), and the specific outside diameter (not exceeding 114.3 mm). All these elements must be met for a product to fall under this particular HTS code.
