Classification of DHA Algal Oil as microbial fats and oils directs tariff treatment based on processing and edibility. DHA Algal oil is classifiable as microbial fats and oils; classification depends on the product's characteristics, extent of chemical modification and whether the mixture or preparation is edible or inedible. HS 2022 Explanatory Notes treat microalgae-derived oils as single cell oils and direct classification in appropriate Chapter 15 headings. Microencapsulated powder retains the oil's essential character and should be classified the same as the oil form. The product is not a food preparation for food-preparation headings and is not the pure DHA chemical.
