Import Tips
• Obtain Certificate of Analysis (CoA) proving 99% purity to distinguish from lower-grade carbonates
• Label as 'chemically defined' per subheading note; ensure no organic stabilizers which could shift to 2831
• Comply with TSCA registration for chemical imports; declare exact CAS number 584-08-7
