Import Tips
• Specify tin plating thickness (e.g
• 40 microinches) and reflow characteristics to meet IPC standards expected by CBP
• Use harmonized alloy designation (e.g
• UNS C75700) on commercial invoice for quick verification
• Avoid coiling wire too tightly during packing to prevent plating cracks that could trigger quality disputes
