Product classification
HS code for Welded steel hollow section: 7306.69
Iron or steel (excluding cast iron), tubes, pipes and hollow profiles (not seamless), n.e.c. in chapter 73, welded, of non-circular cross-section (not square or rectangular cross-section).
Classification of welded steel hollow section under HS 7306.69
Welded steel hollow sections with non-circular cross-sections (excluding square or rectangular) are classified under HS code 7306.69. This code is part of heading 7306, which encompasses tubes, pipes, and hollow profiles that are welded or otherwise joined. The classification is determined by the shape of the profile and the manufacturing method. Subheading 7306.69 serves as a residual category for profiles that are neither circular (7306.30-50) nor square/rectangular (7306.61). These products are typically manufactured by forming steel strips into specialized shapes and welding the seam. They are widely used in architectural design, automotive frames, and specialized machinery where standard geometric shapes do not meet the engineering requirements. The material can be iron or non-alloy steel.

Codes often confused with 7306.69
Common mistake. The most common misclassification for this product is HS code 7306.61, which is reserved exclusively for square or rectangular cross-sections. Importers often use 7306.61 for any non-circular profile, but 7306.69 is the correct code for ovals and other polygons. Another error is using 7306.30, which is only for circular cross-sections. Furthermore, if the hollow section is seamless rather than welded, it must be classified under heading 7304. Finally, if the product is made of stainless steel, it may be subject to different subheadings depending on the specific shape and regional tariff variations, though 7306.69 generally covers non-alloy steel.

How these figures are built
109 countries reported 2025 trade to UN Comtrade in HS 2022, and their own totals are used. Countries that did not report are estimated from what other countries recorded trading with them. Those estimates miss trade with other non-reporting countries, so they can be low, and a non-reporting country can rank higher than shown or be missing from the list. World totals add both and leave out trade between two non-reporting countries. Figures are in current US dollars; reported imports are mostly valued CIF and exports FOB, and exports include re-exports. The UN Comtrade links show the underlying records; they can also list a few reporters left out here (regional groups and older HS editions).
