HS Code for Inactive yeast

Inactive yeast and other dead single-cell micro-organisms are classified under HS code 2102.20. This classification is situated within Chapter 21, "Miscellaneous edible preparations," which encompasses a variety of food-related products that do not fall into more specific chapters. The primary distinction for 2102.20 is the biological state of the yeast. While active yeast (2102.10) is a living organism used for its ability to induce fermentation in dough or liquids, inactive yeast has been processed—usually through heat—to kill the yeast cells. This process stops all enzymatic and fermentative activity, making the product stable for use as a nutritional supplement or flavoring agent. Common examples include nutritional yeast flakes or powders. Additionally, this code covers other single-cell micro-organisms, such as certain types of algae or bacteria, provided they are dead and intended for human consumption or industrial use. It is important to distinguish these from "prepared baking powders" (2102.30), which are chemical leavening agents, and from animal feed preparations (Chapter 23). The classification process requires laboratory confirmation that the yeast is indeed inactive. If any live cells remain that could facilitate fermentation, the product may be reclassified under 2102.10, which often carries different regulatory requirements and import duties.

Products Included

• Nutritional yeast (inactive)
• Dried dead yeast cells
• Dead single-cell proteins (edible)
• Inactive brewer's yeast
• Torula yeast (inactive)

Common Misclassification

The most frequent misclassification is with HS code 2102.10 (active yeast). Importers also confuse this with 2309.90 when the yeast is intended for animal feed, or 2106.90 for general food supplements. If the product contains other ingredients like vitamins in significant amounts, it may be pushed toward 2106.
