Import Tips & Compliance
• Provide assay certificates confirming >99% SrO content to avoid disputes over purity and classification
• Label as hazardous (corrosive/alkaline) per GHS standards and ensure proper UN packaging for transport
• Check for barium contamination; mixtures exceeding thresholds may require reclassification under other strontium/barium subheadings
