Import Tips
• Obtain a detailed Certificate of Analysis (CoA) verifying the enzyme's activity and purity to satisfy FDA and CBP requirements for biotech imports
• Declare as 'Penicillin G Amidase' explicitly on commercial invoices to avoid misclassification into general enzyme categories
• Ensure cold chain documentation for refrigerated shipments, as improper storage can degrade enzyme activity and lead to customs holds
