Import Tips
• Provide detailed alloy composition certificate showing zinc predominance and lead content under 3% tin threshold
• Ensure ingots weigh over 5kg to avoid classification as semi-manufactured under 7403.21
• Verify melting origin documentation to confirm refined status vs master alloys in 7405
