Import Tips
• Remove any non-copper attachments (e.g
• bolts, insulation) before shipping to simplify classification and avoid penalties
• Provide a certificate of analysis showing copper content below 94% by weight, as oxidized surfaces can skew assay results
• Verify whether the busbars were originally refined copper or a copper alloy, as this affects the correct tariff item
