HS Code 7403.29 – Copper; copper alloys n.e.c. in heading no. 7403 (other than master alloys of heading no. 7405)
HS code 7403.29 is the 6-digit subheading for copper, copper alloys n.e.c. in heading no. 7403 (other than master alloys of heading no. 7405). It is used for copper-nickel ingots, copper-beryllium billets, copper-silicon ingots, cupro-nickel alloys (unwrought) and nickel silver ingots.
What HS 7403.29 covers
HS 740329 is the catch-all category for other unwrought copper alloys not specifically classified as brass (copper-zinc) or bronze (copper-tin). This includes a diverse range of specialized alloys such as copper-nickel (cupro-nickel), copper-beryllium, copper-silicon, and nickel silver, among others. These alloys are developed for specific properties like enhanced strength, corrosion resistance, thermal conductivity, or electrical conductivity, making them indispensable in high-tech applications, marine engineering, aerospace, and electronics. Traded as ingots, billets, or other unwrought forms, they serve as raw materials for highly specialized manufacturing. The trade in these alloys is often driven by advanced industrial sectors, with importers seeking materials for demanding applications and exporters being specialized alloy manufacturers with expertise in metallurgy.

Codes often confused with 7403.29
Common mistake. This code covers unwrought copper alloys other than brass (740321) and bronze (740322); it should not be confused with master alloys (740500) which are typically higher concentration additives.
Top exporters and importers of HS code 740329, 2025
In 2025, the largest exporter of HS code 740329 in UN Comtrade data was Thailand, with 13% of world exports; the largest importer in UN Comtrade data was China, with 72% 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).
