Products classified under HTS 1516.30.00.00
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.
Yarrowia lipolytica Microbial Triglycerides
Triglyceride fractions from Yarrowia lipolytica yeast fermentation, rich in oleic acid, used in food and cosmetics. Classified in 1516.30.00.00 due to microbial origin and processes like inter-esterification without further preparation. Refined for stability in emulsions.
DHA-Rich Algal Oil Fraction
Fractionated oil from microalgae like Schizochytrium sp., high in docosahexaenoic acid (DHA), hydrogenated for infant formula use. HTS 1516.30.00.00 applies to this microbial oil not further prepared, distinguishing from crude algal oils. Refined to remove impurities.
Mortierella alpina ARA Oil
Arachidonic acid (ARA)-enriched oil from Mortierella alpina fungus, re-esterified for stability in nutritional products. Falls under 1516.30.00.00 as a processed microbial fat fraction, not chemically modified beyond esterification. Used in vegan omega supplements.
Crypthecodinium cohnii DHA Microbial Fraction
Refined DHA fraction from dinoflagellate Crypthecodinium cohnii, inter-esterified for better absorption. Classified in HTS 1516.30.00.00 for microbial oils partly hydrogenated, suitable for aquaculture feed. Not further prepared into feeds.
Rhizopus oryzae Microbial Lipid Fraction
Lipid extract from Rhizopus oryzae mold, elaidinized for industrial lubricants. HTS 1516.30.00.00 covers this microbial fraction processed but not further prepared. High gamma-linolenic acid content.
Engineered Yeast Omega-3 Oil
Genetically engineered yeast oil producing EPA/DHA, re-esterified and refined. Fits 1516.30.00.00 as synthetic microbial fat not further prepared. Used in pharmaceuticals.
Fungal Mycelial Fat Extract
Partially hydrogenated fat from fungal mycelia, used in margarine analogs. HTS 1516.30.00.00 for microbial fractions refined but not emulsified. Vegan alternative to animal fats.
Bacterial Lipid Fraction for Biodiesel
Lipids from engineered bacteria, inter-esterified for biofuel precursors. Classified 1516.30.00.00 as microbial oil fraction, not transesterified yet. Industrial energy application.
Thraustochytrid Microbial Oil
Oil from Thraustochytrid protists, refined and hydrogenated for pet food. HTS 1516.30.00.00 applies to this microbial source fraction. High omega content.
Oleaginous Yeast Fat Blend
Hydrogenated fats from oleaginous yeasts like Lipomyces, for confectionery. 1516.30.00.00 for processed microbial fractions. Melt point controlled.
Ascomycete Fungal Oil Fraction
Re-esterified oil from Ascomycete fungi for cosmetics. HTS 1516.30.00.00 microbial, refined. Emollient properties.
Probiotic Yeast Lipid Extract
Lipids from probiotic yeasts, elaidinized for supplements. 1516.30.00.00 as microbial fraction. Synbiotic use.
Synthetic Microbial Triglyceride Oil
Lab-produced microbial triglycerides via fermentation, inter-esterified. HTS 1516.30.00.00 for fractions. Pharma grade.
Fermentative Bacterial Fat
Fats from bacterial fermentation, hydrogenated for soaps. 1516.30.00.00 microbial. Industrial.
