Last updated: August 2026 dataInactive yeast products — ranging from crude dried brewers' yeast (2102204000) to refined nutritional yeast and other dead single-cell microorganisms (2102206000) — serve distinct markets: animal feed, human nutrition supplements, and flavor enhancement. Brazil leads US imports under this heading, reflecting its large fermentation and ethanol industry that generates brewers' yeast as a co-product. The US tariff schedule separates dried brewers' yeast in crude form from other inactive yeasts, so the degree of processing and intended end-use are critical classification factors. FDA oversight applies to human-food-grade inactive yeast, while feed-grade material may also be subject to USDA and state feed regulations.

The US schedule carves out dried brewers' yeast in crude form under 2102204000, while other inactive yeasts (including nutritional yeast and refined inactive yeast) fall under 2102202000 or 2102206000. 'Crude' generally means minimally processed — not debittered, not fortified, and not further refined. Importers should obtain supplier documentation confirming processing level to support the correct line selection.
Inactive yeast destined for human food use (e.g., nutritional yeast as a food ingredient or supplement) is regulated by FDA and requires facility registration and Prior Notice filing. Feed-grade inactive yeast is subject to USDA and state feed control regulations, including labeling requirements under the Association of American Feed Control Officials (AAFCO) model bill. Importers must clearly designate intended end-use in entry documentation, as the regulatory pathway differs significantly.
