Import Tips
• Submit copper purity certificate (>99.9% Cu) distinguishing from alloy products; pure copper strips often scrutinized for heading 7409 vs 7408
• Document coil/strip form factor; uncoiling during transit can trigger 'articles of copper' reclassification to 7415
• Avoid common pitfall of declaring as 'foil' if >0.15 mm thick, which shifts to 7409 from 7407
