Product classification
HS code for Bronze billets: 7403.22
Copper, copper-tin base alloys (bronze) unwrought.
Classification of bronze billets under HS 7403.22
Bronze billets are classified under HS code 7403.22 because they represent unwrought forms of copper-tin base alloys. According to the General Rules of Interpretation (GRI) and the Harmonized System Explanatory Notes, heading 7403 covers refined copper and copper alloys in unwrought forms. Subheading 7403.22 specifically targets bronze, which is defined as an alloy of copper and tin, with or without other elements. Billets are semi-finished casting products, typically cylindrical or rectangular, intended for further processing such as extrusion or forging. Because they have not been worked beyond simple casting or sintering, they remain in the unwrought category. If these items were further processed into specific shapes like rods or bars through rolling or drawing, they would move to heading 7407. The classification depends heavily on the metallurgical composition, where tin must be the primary alloying element after copper. Customs authorities require precise chemical analysis to ensure the alloy meets the definition of bronze rather than brass or other copper alloys.

Codes often confused with 7403.22
Common mistake. Bronze billets are frequently confused with bronze bars classified under HS code 7407.29. The distinction lies in the level of processing; 7403.22 is for unwrought forms (cast or sintered), while 7407 is for products that have been rolled, extruded, or drawn. Additionally, they may be misclassified under 7403.21 if the zinc content exceeds the tin content, which would define the material as brass rather than bronze.
Top exporters and importers of HS 740322 (the code used for bronze billets), 2025
In 2025, the largest exporter of HS 740322 (the code used for bronze billets) 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).
