Tin-Plated Brass Electrical Wire from China
This is a thin-gauge wire made from copper-zinc brass alloy, coated with a layer of tin to enhance solderability and corrosion resistance. It falls under HTS 7408.29.10.00 as copper alloy wire (brass) that is coated or plated with metal, specifically excluding high-nickel or high-tin compositions per chapter notes. Commonly used in electronics assembly.

Import Tips
• Verify alloy composition meets brass definition (zinc predominant, nickel <5%, tin <3%) with mill test certificates to avoid reclassification
• Declare plating thickness and metal type accurately; common pitfall is under-declaring coating leading to audits
• Ensure RoHS compliance documentation for electronics use, as tin-plating often serves environmental purposes
