Iron or steel, railway or tramway track construction material, switch blades, crossing frogs, point rods and other crossing pieces.
Classification of railway frogs under HS 7302.30
Railway frogs, also known as crossing frogs, are classified under HS code 7302.30. This classification is governed by Chapter 73 of the Harmonized System, which pertains to articles of iron or steel. Heading 7302 is specifically designated for railway or tramway track construction material of iron or steel. Subheading 7302.30 explicitly includes \"switch blades, crossing frogs, point rods and other crossing pieces.\" A railway frog is a specialized component used at the intersection of two tracks. It allows the flanges of the wheels of a train to pass through the intersection of two rails. The name \"frog\" comes from the visual resemblance of the component to the frog of a horse's hoof. These components are typically made of high-strength manganese steel or cast iron to withstand the extreme impact and wear caused by passing trains. The classification is based on the material (iron/steel) and the specific mechanical role the item plays in the track switching and crossing system. It is important to distinguish these from standard running rails (7302.10) or sleepers (7302.90). The complexity of the frog's geometry and its role in track geometry management place it firmly within the 7302.30 category. This code is used globally to ensure uniform customs treatment for these critical infrastructure components.

Codes often confused with 7302.30
Common mistake. Railway frogs are often misclassified as standard rails under HS code 7302.10. They are also occasionally confused with railway signaling or traffic control equipment under HS code 8608.00, though frogs are mechanical track components rather than signaling devices.
Top exporters and importers of HS 730230 (the code used for railway frogs), 2025
In 2025, the largest exporter of HS 730230 (the code used for railway frogs) in UN Comtrade data was France, with 11% of world exports; the largest importer in UN Comtrade data was Germany, with 9.4% 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).
