Import Tips
• Provide end-use certificates confirming industrial application for metal or compound manufacture to justify 2620 classification
• Conduct particle size and composition testing; misreported copper content leads to penalties
• Package in UN-approved containers for hazmat; bulk shipments require special customs bonds
