Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If contains 5%+ nickel
Copper-nickel base alloys per note (d) classify under 7403.29.
If powdered for master alloy use
Copper powders of refined copper move to heading 7406.
If phosphorus exceeds 4% for master alloy
High phosphorus content qualifies as copper-phosphorus master alloy.
