Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If contains 5%+ nickel
Becomes nickel silver alloy requiring master alloy classification when nickel exceeds 5%.
If purity exceeds 99.3% copper
Pure refined copper without significant alloying elements falls under refined copper heading.
If processed into bars/rod form
Changes from unwrought to semi-manufactured bars/rods when given rectangular cross-section.

Import Tips & Compliance
• 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
