HS Code for Stainless steel hollow section

Stainless steel hollow sections, specifically welded tubes and pipes of circular cross-section, are classified under HS code 7306.40. This classification is situated within Chapter 73, which covers "Articles of iron or steel." Unlike Chapter 72, which deals with primary materials and semi-finished products, Chapter 73 is for more finished goods, including tubes and pipes. Heading 7306 covers "Other tubes, pipes and hollow profiles (for example, open seam or welded, riveted or similarly closed), of iron or steel." The specific sub-heading 7306.40 is dedicated to welded products of circular cross-section made of stainless steel. The classification logic follows the General Rules for the Interpretation (GRI) of the Harmonized System, specifically GRI 1, which states that classification is determined by the terms of the headings and any relative section or chapter notes. Since these sections are welded and circular, they are excluded from heading 7304 (seamless) and specifically included in 7306.40. This code is essential for identifying structural components used in plumbing, industrial piping, and architectural frameworks where stainless steel's corrosion resistance is required. The distinction between welded and seamless is a critical factor in determining the correct tariff rate and regulatory requirements.

Products Included

Common Misclassification

HS code 7304.41 is often confused with this code, but it is strictly for seamless stainless steel tubes and pipes. Another common error is 7306.61, which covers hollow sections with a square or rectangular cross-section. If the product is not circular, 7306.40 cannot be used. Additionally, if the pipe is made of iron or non-stainless steel, it would fall under different sub-headings such as 7306.30. Importers must verify the welding method and cross-sectional shape before assigning the code.

FAQ

What is the HS code for stainless steel hollow section?
