HS Code 7308.90 – Iron or steel; structures and parts thereof, n.e.c. in heading 7308
HS code 7308.90 is the 6-digit subheading for iron or steel, structures and parts thereof, n.e.c. in heading 7308. It is used for structural steel beams, steel columns, roof trusses, industrial platforms and mezzanine structures.
What HS 7308.90 covers
This "catch-all" HS code for iron or steel structures and parts covers all items not specifically classified under bridges, towers, doors/windows, or scaffolding equipment within heading 7308. This broad category includes a vast array of fabricated steel components used in general construction, industrial facilities, and various other structural applications. Examples range from structural beams, columns, and roof trusses for buildings to industrial platforms, mezzanines, and specialized frameworks. Importers are virtually any country with ongoing construction, manufacturing, or infrastructure projects, with major players like the United States, Germany, and Canada. Exporters are typically nations with strong steel production and fabrication industries, such as China, Germany, and South Korea. Key aspects of this trade involve adherence to engineering specifications, material grades (e.g., structural steel, high-strength low-alloy steel), welding standards, and corrosion protection. This code is essential for capturing the diverse and often custom-fabricated steel elements that form the skeletal framework of modern built environments.

Codes often confused with 7308.90
Common mistake. This code is frequently confused with more specific codes within 7308 (e.g., 730810 for bridges, 730820 for towers) if the item's primary function is not clearly defined, or with 7216 (angles, shapes, sections of iron or non-alloy steel) if the items are not considered "structures" but rather basic profiles.
Top exporters and importers of HS code 730890, 2025
In 2025, the largest exporter of HS code 730890 in UN Comtrade data was China, with 35% of world exports; the largest importer in UN Comtrade data was the United States, with 10% of world imports. Countries that did not report 2025 data are estimated from partner records, which can understate them.

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).
