Cupro-Nickel Coated Electrical Wire
This is a thin wire made from a copper-nickel base alloy (cupro-nickel) and coated with a layer of silver to improve conductivity and resist corrosion. It is classified under tariff item 7408.22.00 because it is a wire of copper-nickel base alloy, regardless of the silver plating.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If the wire is of refined copper without alloying elements
Refined copper wire is classified under a different tariff item in the same heading.
If the wire is of other copper alloys not specified elsewhere
Other copper alloy wires fall under this alternative when not cupro-nickel or nickel silver.

Import Tips & Compliance
• Ensure the wire's copper-nickel alloy composition meets the definition of copper-nickel base alloys under the Customs Tariff, with nickel predominating over other elements except copper
• Declare the wire's cross-sectional dimension and whether it is coated, as this affects classification
• Keep supplier certificates of analysis to confirm alloy composition for CBSA verification
