7306.11.00 - Welded, of stainless steel

This HTS category, 7306.11.00, specifically encompasses welded tubes, pipes, and hollow profiles made of iron or steel that are designed and used for oil or gas pipelines. The key defining characteristic here is the method of construction – welded – and the material – stainless steel – combined with the intended application for transporting oil or gas. This distinguishes it from other categories within 7306 that might cover pipes of different constructions (e.g., seamless) or those not specifically designated for pipeline use.

Within this category, the sub-classification relies on a precise physical dimension: the outside diameter of the pipe. Subcategory 7306.11.00.10 covers pipes with an outside diameter not exceeding 114.3 millimeters, while subcategory 7306.11.00.50 addresses those with an outside diameter exceeding 114.3 millimeters. This distinction is crucial for tariff purposes and is often determined by industry standards and specifications relevant to the oil and gas sector.

It is important to note that while the parent category covers welded tubes, pipes, and hollow profiles of iron or steel generally, this specific line item narrows the scope to those constructed from stainless steel and intended for oil or gas pipelines. Sibling category 7306.19 covers "other" line pipe of a kind used for oil or gas pipelines, implying that 7306.11.00 is reserved for the welded stainless steel variants specifically.
