Import Tips
• Verify alloy composition meets copper-zinc base alloy definition (zinc predominant, nickel <5%, tin <3%) with mill test certificates
• Measure and document exact thickness (<1.6mm) and width (<500mm) to avoid reclassification to wider strip codes
• Ensure proper packing to prevent scratching; common pitfall is inadequate edge protection leading to customs holds
