Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If copper-zinc base alloy (brass) rather than bronze
Brass alloys where zinc predominates fall under copper alloy plates/sheets excluding bronze per subheading note (a).
If thickness less than 5mm but over 0.15mm
Thinner bronze sheets in the same alloy family classify under 'other' thickness category within 7409.39.
If supplied in coil form rather than flat sheets
Coiled strip/plate of bronze over 0.15mm thickness falls under Chapter 74 heading for refined copper in coils.

Import Tips & Compliance
• Provide mill test certificates verifying copper-tin base alloy composition per subheading note (b), with tin predominating
• Ensure accurate thickness measurement documentation; products under 5mm shift to other subheadings
• Declare exact alloy grade (e.g
• UNS C65500) to avoid reclassification during customs review
