HS Code 7403.22 – Copper; copper-tin base alloys (bronze) unwrought
HS code 7403.22 is the 6-digit subheading for copper, copper-tin base alloys (bronze) unwrought. It is used for bronze ingots, bronze billets, bronze slabs, phosphor bronze ingots and aluminum bronze ingots.
What HS 7403.22 covers
HS 740322 pertains to unwrought copper-tin base alloys, commonly known as bronze. Bronze is an ancient and enduring alloy, valued for its strength, hardness, wear resistance, and corrosion resistance, particularly in marine environments. In its unwrought forms, such as ingots, billets, or slabs, it is used as feedstock for casting and machining into components for bearings, gears, propellers, sculptures, and specialized industrial parts. The trade in unwrought bronze is crucial for industries requiring robust and durable materials, from shipbuilding to artistic foundries. Importers are typically manufacturing hubs with demand for high-performance alloys, while exporters are often specialized foundries and alloy producers. The specific composition of bronze alloys can vary widely, catering to diverse application requirements.

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).
