HS Code 7306.90 – Iron or steel (excluding cast iron); tubes, pipes and hollow profiles (not seamless), n.e.c. in chapter 73

HS code 7306.90 is the 6-digit subheading for iron or steel (excluding cast iron), tubes, pipes and hollow profiles (not seamless), n.e.c. in chapter 73. It is used for galvanized steel conduits, black steel pipes for general use, structural steel sections for agricultural equipment, fence posts and scaffolding tubes.

What HS 7306.90 covers

This 'not elsewhere specified' category serves as a catch-all for welded iron or steel tubes, pipes, and hollow profiles that do not fit into the more specific subheadings of Chapter 73. It encompasses a wide array of non-seamless products, often used in less common applications or those with unique specifications not covered by standard circular, square, or rectangular profiles. Trade in these goods is driven by diverse industrial needs, from agricultural machinery to specialized structural components and general fabrication. Importers include manufacturers seeking specific dimensions or properties, while exporters are typically steel mills and fabricators offering a broad product range. Key aspects for trade include material grade, wall thickness, adherence to specific industry standards, and the ability to fulfill custom orders for varied industrial applications.

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).
