Import Tips
• Provide beneficiation flow charts proving no chemical reagents altered the mineral composition
• Certify BaCO3 percentage via independent lab tests to match declared value and avoid undervaluation claims
• Segregate from synthetic grades in shipping to prevent cross-contamination disputes
