Product classification
HS code for Unwrought bronze: 7403.22
Copper, copper-tin base alloys (bronze) unwrought.
Classification of unwrought bronze under HS 7403.22
HS code 7403.22 is dedicated to unwrought bronze, which the Harmonized System defines as an alloy of copper and tin. For a product to be classified here, the tin content must be significant, and in cases where other elements are present, the tin must predominate by weight over each of those other elements. The "unwrought" status indicates that the bronze is in a primary form, such as an ingot or a block, which has not been worked beyond simple casting. These materials serve as the feedstock for various industrial applications, including the production of bearings, bushings, and marine hardware. The classification falls under heading 7403, which is reserved for refined copper and copper alloys that have not been manufactured into semi-finished products like sheets or tubes. Distinguishing bronze from other copper alloys like brass (copper-zinc) or cupro-nickel is a common challenge that requires a detailed mill test report or chemical composition analysis to ensure compliance with the HS nomenclature. This code is essential for the heavy machinery and maritime industries where bronze's corrosion resistance and strength are required.

Codes often confused with 7403.22
Common mistake. The most common misclassification is confusing bronze with brass, which is classified under 7403.21. Another error is classifying other copper alloys, such as cupro-nickel or copper-nickel-zinc (nickel silver), under this code; these belong under 7403.29. Additionally, bronze scrap is classified under 7404.00, and worked bronze bars are under 7407.29.
Top exporters and importers of HS 740322 (the code used for unwrought bronze), 2025
In 2025, the largest exporter of HS 740322 (the code used for unwrought bronze) in UN Comtrade data was Spain, with 17% of world exports; the largest importer in UN Comtrade data was China, with 27% 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).
