Import Tips
• Provide fermentation batch records to prove microbial production and avoid vegetable oil misclassification
• Check for contaminants; FDA prior notice required for food imports—pitfall is incomplete prior notification
• Use precise invoicing for fractions (e.g
• % ARA content) to prevent customs revaluation
