Import Tips
• Obtain FDA prior approval via a Food Contact Notification or GRAS status, as rennet is a food processing aid
• Provide certificates of analysis confirming enzymatic activity and absence of contaminants like antibiotics
• Avoid misclassification as a general enzyme under 3507.90; specify rennet origin to prevent customs disputes
