Import Tips
• Verify purity certificates (typically 98%+ for USP grade) to meet FDA food/supplement import standards
• Include Certificate of Analysis (CoA) showing optical purity (L-form vs DL) to avoid reclassification
• Label as 'food grade' or 'pharma grade' accurately to prevent CBP scrutiny on end-use claims
