HS Code 7308.10 – Iron or steel; structures and parts thereof, bridges and bridge-sections
HS code 7308.10 is the 6-digit subheading for iron or steel, structures and parts thereof, bridges and bridge-sections. It is used for steel bridge girders, prefabricated bridge sections, steel bridge trusses, orthotropic steel decks and bridge expansion joints (steel).
What HS 7308.10 covers
This HS code specifically covers structures and parts made of iron or steel that are designed for bridges and bridge-sections. This includes the massive steel girders, trusses, decks, and other fabricated components that form the backbone of modern transportation infrastructure. The trade in these goods is highly specialized, driven by large-scale civil engineering projects and government infrastructure spending. Major importers are typically countries undergoing significant infrastructure development or replacement, such as developing nations expanding their road and rail networks, or developed nations upgrading aging infrastructure. Examples include countries in Southeast Asia, Africa, and parts of Europe and North America. Exporters are usually nations with advanced heavy manufacturing capabilities and expertise in structural steel fabrication, like China, Germany, Japan, and South Korea. Key aspects of this trade involve adherence to stringent engineering standards, seismic resistance, load-bearing capacities, and corrosion protection, given the critical safety and longevity requirements of bridges.

Codes often confused with 7308.10
Common mistake. This code can be confused with 730890 (other iron or steel structures) if the specific use for bridges is not clear, or with 730820 (towers and lattice masts) due to similar structural steel fabrication.
Top exporters and importers of HS code 730810, 2025
In 2025, the largest exporter of HS code 730810 in UN Comtrade data was Bahrain, with about 24% of world exports; the largest importer in UN Comtrade data was Saudi Arabia, with 28% of world imports. The United Arab Emirates did not report 2025 data, and its estimate from partner records misses its trade with other countries that did not report: in 2024 that was 87% of its imports here ($87M, CEPII BACI), so it may also belong among the top importers.

How these figures are built
109 countries reported 2025 trade to UN Comtrade in HS 2022, and their own totals are used. Countries marked * did not, so their figures add up what other countries recorded trading with them, and their exports are valued at buyers' CIF prices. 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).

What are common misclassifications for HS code 730810?
This code can be confused with 730890 (other iron or steel structures) if the specific use for bridges is not clear, or with 730820 (towers and lattice masts) due to similar structural steel fabrication.
Which countries are the top exporters of goods under HS code 730810?
In 2025, the top exporters of HS code 730810 in UN Comtrade data were Bahrain (about $338M, 24% of world exports), China ($173M) and Italy ($66M). World exports came to about $1.4B, adding countries' reported figures and partner-based estimates for those that did not report (UN Comtrade data). Countries that did not report 2025 data are estimated from partner records, which can understate them.
Which countries are the top importers of goods under HS code 730810?
In 2025, the top importers of HS code 730810 in UN Comtrade data were Saudi Arabia ($413M, 28% of world imports), Norway ($76M) and Canada ($62M). World imports came to about $1.5B, adding countries' reported figures and partner-based estimates for those that did not report (UN Comtrade data). The United Arab Emirates did not report 2025 data, and its estimate from partner records misses its trade with other countries that did not report: in 2024 that was 87% of its imports here ($87M, CEPII BACI), so it may also belong among the top importers.
How is HS code 730810 structured?
HS code 730810 is a 6-digit subheading under the Harmonized System. The first 2 digits (73) identify the chapter, digits 3-4 (08) identify the heading, and digits 5-6 (10) specify the subheading. This code is standardized globally by the World Customs Organization.
What is the Brazil NCM code for HS code 730810?
