Import Tips & Compliance
• Verify purity and chemical composition via Certificate of Analysis to confirm classification as 'other sulfates'
• Ensure SDS includes CAS number 151-21-3 and proper labeling for hazardous materials if concentration exceeds thresholds
• Avoid misclassification as finished cosmetic by importing in bulk powder form, not packaged for retail
