HS Code for Welded steel rectangular tube

Welded steel rectangular tubes are classified under HS code 7306.61. This classification falls under Chapter 73, which covers articles of iron or steel. Heading 7306 is designated for "Other tubes, pipes and hollow profiles (for example, open seam or welded, riveted or similarly closed), of iron or steel." Within this heading, the code 7306.61 is specific to tubes and pipes that have a square or rectangular cross-section and are not seamless. The classification process requires identifying the manufacturing method (welding vs. seamless) and the geometric profile. Since these tubes are formed from flat-rolled steel and then joined by a longitudinal or spiral weld, they are excluded from heading 7304, which is reserved for seamless tubes. The rectangular shape further narrows the classification to 7306.61, distinguishing it from circular or other non-rectangular profiles. These products are widely used in construction, furniture manufacturing, and automotive frames due to their structural efficiency.

Products Included

• Welded rectangular hollow sections (RHS)
• Welded square hollow sections (SHS)
• Electric Resistance Welded (ERW) rectangular steel tubing
• Structural steel box sections (welded)
• Cold-formed welded rectangular tubes

Common Misclassification

A common error is classifying these products under 7304.41 or 7304.90, which are for seamless tubes. If there is any visible or internal weld seam, 7306 must be used. Another misclassification occurs with 7306.30, which is for welded tubes of circular cross-section. Additionally, if the tube is further worked into a specific part for a structure (like a finished truss), it might be moved to 7308.90, though the raw tube remains 7306.61.

FAQ

What is the HS code for welded steel rectangular tube?

The specific HS code for welded tubes and hollow profiles of square or rectangular cross-section is 7306.61.

Does the steel grade affect the 7306.61 classification?

While the steel grade (e.g., stainless vs. alloy) may affect the 8-digit or 10-digit statistical suffix, the 6-digit HS code 7306.61 remains the primary classification for welded rectangular profiles.
