HS Code for Welded stainless steel pipe
Welded stainless steel pipes are classified under HS code 7306.40. This classification is based on the material composition, the manufacturing method, and the cross-sectional shape. Chapter 73 covers articles of iron and steel, and heading 7306 is reserved for tubes, pipes, and hollow profiles that are not seamless (e.g., welded, riveted, or similarly closed). For a product to fall under 7306.40, it must be made of stainless steel, which is defined in the Chapter 72 notes as alloy steel containing by weight 1.2% or less of carbon and 10.5% or more of chromium. Furthermore, the pipe must have a circular cross-section. The welding process typically involves forming a stainless steel strip into a cylinder and joining the edges using longitudinal or spiral welding techniques such as TIG or laser welding.

Common Misclassification
Welded stainless steel pipes are often confused with seamless stainless steel pipes, which are classified under HS code 7304.41 (cold-drawn) or 7304.49 (other). Seamless pipes are manufactured through extrusion or piercing and do not have a weld seam. Another common misclassification occurs with HS code 7306.30, which is for welded pipes of non-alloy steel. If the chromium content is below 10.5%, the pipe cannot be classified as stainless steel. Additionally, if the stainless steel pipe has a square or rectangular cross-section, it must be classified under 7306.61 rather than 7306.40.
