Cupro-Nickel Coated Electrical Wire
This is a thin wire made from copper-nickel base alloy (cupro-nickel), coated with a layer of silver for enhanced conductivity and corrosion resistance. It falls under HTS 7408.22.10.00 because it is wire of copper-nickel base alloys that has been plated with metal, distinguishing it from uncoated variants. Commonly used in high-reliability electronics like aerospace sensors.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If uncoated or not plated with metal
Unplated cupro-nickel wire shifts to the general copper-nickel base alloy wire subheading without metal coating provision.
If made of copper-zinc base alloys (brass) instead
Brass alloys (copper-zinc predominant, nickel <5%, tin <3%) fall under a separate alloy-specific subheading per chapter notes.
If insulated for electrical use and exceeding wire tolerances
Insulated copper alloy wire for electrical purposes is classified in Chapter 85 based on function rather than material alone.

Import Tips & Compliance
• Verify alloy composition meets copper-nickel base alloy definition (nickel predominates, zinc ≤1%) with certified mill test reports to avoid reclassification
• Declare plating material (e.g
• silver, nickel) precisely on entry documents, as it triggers specific HTS subheading
• Ensure compliance with ASTM standards for coated wire to prevent customs holds on quality grounds
