Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If copper-zinc brass alloy instead of bronze
Brass alloys (zinc predominant, tin <3%) shift to copper alloy subheading 7409.21 per subheading note (a).
If refined copper, not alloyed
Pure copper (>99.3% Cu) without tin alloying falls under 7409.11, excluding alloy definitions.
If bimetal composite with steel backing
Clad or composite metal sheets (non-copper base) classify under Chapter 74 note 2(b) as worked products.

Import Tips & Compliance
• Verify alloy composition meets copper-tin base alloy definition (tin predominant, zinc <10%) with mill test certificate
• Ensure thickness >0.15mm but <5mm and width ≥500mm measured per ASTM standards to avoid reclassification
