Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If of copper-nickel-zinc alloy (nickel silvers)
Products with ≥5% nickel content shift to copper-nickel-zinc base alloys, changing subheading within Chapter 74.
If of refined copper, not alloy
Pure copper foil (no alloying elements like zinc) falls under the refined copper subheading in 7409.
If other copper alloy not brass-specified
Copper alloys not meeting brass criteria (e.g., high tin) classified under residual copper alloy foil.

Import Tips & Compliance
• Verify alloy composition meets copper-zinc base alloy definition (zinc predominant, nickel <5%, tin <3%) with mill test certificates
• Measure thickness excluding any backing; must be ≤0.15mm to qualify—common pitfall is including adhesive layers
• Provide detailed technical specs and end-use declaration to avoid misclassification as thicker sheet under 7411
