Import Tips
• Provide supplier specs confirming CMD type (e.g
• gamma-MnO2) and particle size for battery compatibility
• Ensure packaging labels indicate 'for primary batteries' to prevent scrutiny under general chemical headings
• Watch for contamination issues; impure lots may be rejected or reclassified, delaying clearance
