Products classified under HTS 1515.60.05.00
Refined Microbial Algal Oil DHA
This is a refined fraction of microbial oil produced by fermentation of algae, rich in docosahexaenoic acid (DHA), used in infant formula and nutritional supplements. It falls under HTS 1515.60.05.00 as a microbial fat and oil fraction, not chemically modified. The product is extracted and refined from microbial sources without altering its chemical structure.
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.
Fermented Yeast Derived Microbial Fat
Unrefined microbial fat extracted from oleaginous yeast cultures like Yarrowia lipolytica, used in biodiesel and oleochemicals. It qualifies under HTS 1515.60.05.00 as other fixed microbial fats and fractions, not chemically modified. The fat is separated via physical centrifugation without structural changes.
Refined Schizochytrium Algal Oil Fraction
A DHA-enriched fraction from Schizochytrium sp. microalgae fermentation, refined for pharmaceutical and food use. Falls under HTS 1515.60.05.00 for microbial oils and fractions, physically refined only. Not chemically modified, maintaining triglyceride structure.
Oleaginous Fungal Lipid Fraction
Lipid fraction from oleaginous fungi like Blakeslea trispora, rich in beta-carotene precursors, for nutraceuticals. Under HTS 1515.60.05.00 as microbial oil fraction, refined physically. Maintains natural fat profile.
Bulk Microbial Triglyceride Oil
Bulk triglyceride-rich oil from engineered microbial hosts for industrial lubricants. HTS 1515.60.05.00 covers this fixed microbial fat, unrefrigerated and unrefined. Biotechnologically produced without modification.
Refined Thraustochytrid Microbial Fat
Fat from Thraustochytrid protists, refined for omega-3 supplements. Fits HTS 1515.60.05.00 as microbial fraction. Physical refining only.
Fungal Beta-Carotene Rich Oil Fraction
Fraction from fungal fermentation high in beta-carotene oils for fortification. HTS 1515.60.05.00 for microbial fats.
Microalgal EPA Oil Concentrate
EPA-concentrated fraction from microalgae, for heart health supps. Under 1515.60.05.00 as refined microbial oil.
Crypthecodinium Cohnii Microbial DHA Oil
Whole microbial oil from Crypthecodinium cohnii dinoflagellates, used in aquaculture feeds, supplied unrefrigerated. Classified in HTS 1515.60.05.00 as microbial fat, not fractionated or chemically altered. Derived via heterotrophic fermentation.
