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
