Import Tips
• Document industrial end-use for metal/compound extraction to distinguish from waste under 2621
• Include detailed chemical analysis showing mainly copper with silver content for customs valuation
• Avoid bulk packaging pitfalls; label as industrial residue, not ore, to prevent Chapter 26 reclassification
