Cupro-Nickel Coated Electrical Wire from China
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.

Import Tips
• 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
