Import Tips & Compliance
• Use ISBT numbering system for bulk vitamin packaging and provide cleaning validation for multi-product drums
• Include melting point (234-237°C) and assay data to distinguish from lower-purity industrial grades
• File FDA supplement filings pre-arrival; misdeclaration as 'food additive' instead of 'vitamin' causes delays
