Single Cell Microbial Oil
Single cell oil produced by microbial fermentation of yeast or fungi, containing high levels of polyunsaturated fatty acids like DHA and EPA. This falls under HTS 1516.30.00.00 as it is a microbial fat and oil fraction, often partly hydrogenated or refined for nutritional supplements. It is not further prepared into emulsions or other products.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If merely denatured but otherwise unchanged
Chapter note excludes merely denatured microbial fats from 1516, directing to 1518 for animal/veg/microbial fats.
If chemically defined as fatty acid distillates
If processed beyond simple hydrogenation into industrial fatty substances, it falls under 3823 for chemical preparations.
If sold as a formulated food additive or supplement
Further preparation into food preparations moves it from Chapter 15 oils to Chapter 21.

Import Tips & Compliance
• 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
