Single Cell Microbial Oil ARA Fraction
A fraction of arachidonic acid (ARA)-rich oil derived from fermented Mortierella alpina fungi, used in nutritional products. Classified under HTS 1515.60.05.00 for microbial fats and their fractions, whether refined but unmixed. It remains a fixed vegetable-like microbial fat without chemical modification.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If merely denatured for non-food use
Denatured microbial oils classify under the undenatured heading 1515 per Chapter Note, but denatured forms may shift based on use.
If highly purified as a vitamin A/D carrier
Purified microbial oil fractions functioning as provitamins or carriers move to Chapter 29 for unsaturated acyclic compounds.
If imported as a compound food supplement
If blended with other ingredients for direct consumption, it becomes a food preparation under 2106.

Import Tips & Compliance
• Provide fermentation batch records to prove microbial production and avoid vegetable oil misclassification
• Check for contaminants; FDA prior notice required for food imports—pitfall is incomplete prior notification
• Use precise invoicing for fractions (e.g
• % ARA content) to prevent customs revaluation
