Import Tips
• Require USP/NF certificate; customs frequently rejects without pharmacopeia compliance documentation
• Label as 'food additive' not 'chemical' to qualify for food import channels and avoid chemical weapon scrutiny
• Batch testing for arsenic (<3 ppm) mandatory; common rejection reason in recent FDA import alerts
