Hydrogenated Microbial Fats, Oils & Fractions imports of $958K in July 2026 ran 77% above the year-to-date monthly average of $541K.
Last updated: July 2026 dataDerived from fermentation-based microbial sources rather than conventional plant or animal feedstocks, these hydrogenated, interesterified, or similarly processed fats and oils occupy a specialized niche in nutraceutical, infant formula, and functional food ingredient supply chains. The entire heading is captured in a single 10-digit line (1516300000), simplifying classification but placing the analytical burden on correctly distinguishing microbial origin from algal or other non-conventional sources. Norway and France are the leading suppliers to the US market, reflecting the concentration of advanced fermentation and biotechnology capacity in those countries. Because these products enter the food supply, FDA review applies at importation.

Microbial fats and oils are produced by microorganisms — including fungi, bacteria, or microalgae — through fermentation, rather than being extracted from conventional plant tissue. Classification under 151630 requires that the fat or oil originate from a microbial source; oils derived from macroalgae or conventional oilseeds would fall under different headings. When the biological origin is ambiguous, supporting documentation such as a certificate of origin or technical data sheet from the manufacturer is essential.
Because these are novel food-grade ingredients, importers should be prepared to provide FDA with a detailed product description, the producing microorganism's identity, processing method, and any applicable GRAS determination or food additive petition. Prior notice to FDA is required for all food shipments. Admissibility and classification of these products can be complex; consulting a licensed customs broker and regulatory counsel is strongly advised.
