Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If tin content 3%+ making it bronze alloy
Per note (b), higher tin shifts to copper-tin base alloy (bronze) subheading
If clad with other metals
Metal-clad copper alloy sheets classify under iron/steel chapter when steel predominates
If thickness ≤0.15mm
Thinner copper alloy sheets/strips have separate tariff provisions
