• Submit detailed chemical assays confirming mainly copper and zinc content for correct subheading
• Declare intended industrial use (e.g
• zinc recovery) to distinguish from waste under environmental regs
• Watch for particle size; coarse residues might overlap with ore statistical notes if not processed
