Import Tips & Compliance
• Include EP Certificate of Analysis with assigned content value and chromatographic purity; essential for laboratory reference standard verification
• Declare specific use as 'Analytical Reference Standard' to qualify for potential duty exemptions under laboratory reagent provisions
• Package quantities typically <1g; ensure child-resistant packaging and proper hazard labeling for DEA Schedule III controlled substance
