Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If supplied as master alloys
Powder forms of refined copper classify under 7405, not solid bars.
If drawn into fine wire rod
Wire rod <6mm for further drawing goes to Chapter 74 wire headings.
If insulated for electrical use
Winding wire with insulation classifies by function under Chapter 85.

Import Tips & Compliance
• Require vacuum melt certification; electrolytic refined alone insufficient for OFHC claims
• Annealed tempers common; hard-drawn may need separate proof
• Anti-dumping checks if from certain origins
