HS Code for Steel hollow section

Steel hollow sections that are not seamless and do not fit into specific categories like circular or square cross-sections are classified under HS code 7306.90. This code resides in Chapter 73, which covers articles of iron and steel. Heading 7306 is dedicated to tubes, pipes, and hollow profiles that are welded, riveted, or similarly closed. The subheading 7306.90 serves as a residual category for "other" profiles that are not specifically mentioned in the preceding subheadings (such as 7306.30 for circular sections or 7306.61 for square/rectangular sections). These products are essential in structural engineering, furniture manufacturing, and automotive frames. The classification assumes the product is a finished or semi-finished hollow profile intended for structural or mechanical use, rather than a raw ingot or a finished assembly like a building frame.

Products Included

• Welded steel hollow profiles (non-standard shapes)
• Open-seam steel tubes
• Riveted iron hollow sections
• Specialized elliptical hollow sections
• Cold-formed welded profiles

Common Misclassification

The most common misclassification occurs with HS code 7304, which is strictly for seamless tubes and pipes. If the hollow section has a visible weld seam or was joined by riveting, it cannot be in 7304. Furthermore, if the section is square or rectangular, it should be classified under 7306.61, and if it is circular and made of non-alloy steel, it belongs under 7306.30. Large diameter pipes (exceeding 406.4 mm) are classified under 7305.

FAQ

What is the HS code for steel hollow section?

The HS code for other welded or non-seamless steel hollow sections not specified elsewhere is 7306.90.

What is the difference between 7304 and 7306?

HS code 7304 is reserved for seamless products manufactured without a weld seam, whereas 7306 covers products that are welded, riveted, or otherwise joined during the manufacturing process.
