Import Tips
• Verify microbial origin via Certificate of Analysis (COA) to confirm classification under 1516.30; animal/vegetable sources shift to other headings
• Ensure FDA prior notice and GRAS status documentation for food-grade imports to avoid detention
• Label peroxide value and fatty acid profile accurately to prevent misclassification as crude oils
