HS code for Bronze ingots: 7403.22
Copper, copper-tin base alloys (bronze) unwrought.
Classification of bronze ingots under HS 7403.22
Bronze ingots are classified under HS code 7403.22. Like billets, ingots are considered unwrought forms of copper-tin alloys. Heading 7403 is reserved for refined copper and copper alloys that have not been worked. Ingots are typically produced by pouring molten metal into molds and are intended for remelting or further processing in foundries. The classification 7403.22 is specific to bronze, where tin is the predominant alloying element. The Harmonized System distinguishes between refined copper (7403.1x) and copper alloys (7403.2x). Within the alloys, bronze is separated from brass (copper-zinc) and cupro-nickel. The physical state of the ingot—being a primary form of the metal—is the deciding factor for this classification. These items must not have been rolled, forged, or otherwise shaped into finished goods. They are often traded as raw material for the production of bearings, bushings, and marine hardware. Documentation should clearly state the tin content to justify the use of the bronze-specific subheading.

Codes often confused with 7403.22
Common mistake. Bronze ingots are sometimes misclassified under 7403.21 (brass ingots) if the chemical composition is not verified, as brass contains zinc as the main alloy. They may also be confused with 7405.00, which covers master alloys of copper. Master alloys are used for adding specific elements to a melt and are not intended for direct casting into finished parts like standard bronze ingots.
Top exporters and importers of HS 740322 (the code used for bronze ingots), 2025
In 2025, the largest exporter of HS 740322 (the code used for bronze ingots) 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).

How do I classify Bronze ingots for customs?
Bronze ingots is classified under HS code 740322 — Copper; copper-tin base alloys (bronze) unwrought. This is a 6-digit subheading level code.
What defines bronze as unwrought in the HS system?
Unwrought bronze refers to metal in primary forms like ingots, blocks, or pigs that have been cast or sintered and have not undergone mechanical working like rolling or drawing.
Which countries are the top exporters of bronze ingots (HS 740322)?
In 2025, the top exporters of HS 740322 (the code used for bronze ingots) in UN Comtrade data were Spain ($107M, 17% of world exports), Japan ($79M) and Germany ($69M). World exports came to about $638M, 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.
