Import Tips
• Verify alloy composition meets copper-zinc base alloy definition (zinc predominant, nickel <5%, tin <3%) with mill test certificates
• Measure thickness excluding any backing; must be ≤0.15mm to qualify—common pitfall is including adhesive layers
• Provide detailed technical specs and end-use declaration to avoid misclassification as thicker sheet under 7411
