Import Tips
• Submit melting point and solubility data to demonstrate master alloy purpose, preventing confusion with finished copper alloy products
• Label shipments clearly as 'master alloy for remelting' to distinguish from semi-finished copper alloy articles in 7406
• Verify chromium and zirconium contents comply with copper-zinc base alloy exclusions in subheading notes
