Import Tips
• Include chemical composition analysis confirming brass alloy per subheading note (a); customs may test samples
• Declare surface finish and flatness tolerances in documentation to distinguish from backed foils in 7410.21
• Avoid shipping in coils >1m wide, which may trigger plate classification under 7417 if misinterpreted
