Overview

This HTS category, 7306.40, encompasses other welded tubes, pipes, and hollow profiles made of stainless steel, specifically those with a circular cross-section. These items are not intended for use as line pipe for oil or gas pipelines, nor as casing or tubing for oil or gas drilling. They also differ from those made of nonalloy or other alloy steels, as the defining characteristic here is the use of stainless steel.

The distinction from sibling categories lies primarily in the material composition. While other categories within 7306 cover welded tubes of circular cross-section made from nonalloy steel (7306.30) or other alloy steels (7306.50), this category is exclusively for stainless steel. Furthermore, it is distinct from welded, noncircular hollow profiles.

Within this stainless steel classification, further subdivision is based on the wall thickness of the tubing. Subcategory 7306.40.10 covers items with a wall thickness less than 1.65 mm, while 7306.40.50 includes those with a wall thickness of 1.65 mm or greater. This differentiation allows for more precise classification based on the physical dimensions and intended application of the stainless steel tubing.
