Import Tips

Verify alloy composition meets copper-zinc base alloy definition (zinc predominant, nickel <5%, tin <3%) with mill test certificates

Ensure thickness >0.15mm but <5mm and width <500mm; measure precisely to avoid reclassification to wider strip categories

Provide documentation on flat-rolled status vs. worked shapes to prevent shifts to Chapter 74 headings for profiles or foil
