Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If of other copper alloys like nickel silver
Copper-nickel-zinc alloys with ≥5% nickel are classified separately under alloy wire subheadings.
If pre-insulated with enamel
Even thin film insulation moves it to Chapter 85 as winding wire for electrical machinery.
If clad with silver or other metal
Clad or plated copper wire changes to Chapter 74 clad products based on surface treatment.

Import Tips & Compliance
• Use ASTM B3 standards documentation for annealed bare wire to support refined copper purity claims
• Avoid bundling with insulated wire in same shipment to prevent commingling and classification disputes
