Import Tips & Compliance
• Provide assay results (>98% purity) to distinguish from hydrates or impurities affecting classification
• Declare as 'chemically defined' per Chapter 28 Note 1 to prevent fallback to preparations heading
• Monitor cobalt content for CITES-like export controls from source countries
