Import Tips
• Classify based on origin as ore concentrate, not as 2620 residues unless industrially processed for extraction
• Laboratory certificates must specify copper assay for statistical reporting accuracy
• Beware reclassification if copper content suggests base metal concentrate under Chapter 26
