Import Tips
• Submit alloy analysis confirming copper-tin bronze per Chapter 74 subheading note (tin predominant over other elements)
• Declare exact tin content (8-12%) to distinguish from brass flakes and prevent 7406.10 misclassification
• Use nitrogen-flushed packaging to prevent oxidation common in tin-bearing copper alloys
