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
