HS Code 7405
Copper Master Alloys
HS code 7405 covers copper master alloys, which are concentrated metallic compositions used as additives or deoxidisers in metal production.
HS Code 7405 — Copper Master Alloys
Master alloys are compositions containing copper and another element (like phosphorus or manganese) in high concentrations. They are not used for making finished products directly, but are added in small amounts during smelting to improve properties or act as deoxidisers.
What's included
- Phosphor copper
- Copper-manganese master alloys
- Copper-boron master alloys
- Copper-silicon master alloys
What's excluded
- Copper phosphide with >15% Phosphorus → use
2853(High-phosphorus chemical compounds move into the chemicals chapter.)
Common examples
- 15% Phosphor-copper shots
- Copper-manganese 30/70 ingots
- Copper-iron master alloy slabs
Frequently asked questions
What is the primary use of these alloys?
They are used by foundries to introduce specific elements into a melt where the pure element might be difficult to handle or mix.
