Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If the product is further processed into a compound feed or feed supplement
Heading 23.09 covers products of a kind used in animal feeding that have lost the essential characteristics of the original material, which may apply if the yeast cake is blended with other ingredients.
If the yeast biomass is marketed primarily as a yeast product rather than an oil extraction residue
Inactive yeasts are classified under heading 21.02 when not presented as residues from oil extraction.
