HS Code 7405.00 – Copper; master alloys of copper
HS code 7405.00 is the 6-digit subheading for copper, master alloys of copper. It is used for copper-phosphorus master alloy, copper-boron master alloy, copper-manganese master alloy, copper-chromium master alloy and copper-iron master alloy.
What HS 7405.00 covers
This HS code covers master alloys of copper, which are concentrated forms of alloying elements used to introduce specific properties into copper or other non-ferrous metals during the casting or melting process. These alloys are crucial for metallurgical industries, allowing manufacturers to precisely control the composition and characteristics of their final products, such as enhancing strength, corrosion resistance, or machinability. Major importers and exporters include countries with robust metal production and manufacturing sectors, like China, Germany, and the USA, where foundries and specialized metal producers rely on these inputs. The trade in master alloys is driven by the global demand for high-performance metals in sectors ranging from automotive and aerospace to electronics and construction. Understanding the specific alloying elements and their intended application is key to navigating this niche but vital segment of the copper trade.

Codes often confused with 7405.00
Common mistake. This code can be confused with unwrought copper (740300) if the 'master alloy' aspect is overlooked, or with other copper alloys in primary forms (74032X) if the specific concentration and purpose are not clearly identified.
Top exporters and importers of HS code 740500, 2025
In 2025, the largest exporter of HS code 740500 in UN Comtrade data was Belgium, with 45% of world exports; the largest importer in UN Comtrade data was Germany, with 30% 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).
