Last updated: April 2026 dataSpent grains, yeast slurries, and other dregs from brewing and distilling operations are consolidated under a single tariff line (2303300000), covering both pelleted and non-pelleted forms. Brewers' spent grain is a widely used, cost-effective protein and fiber source in dairy and beef cattle rations, while distillers' dried grains with solubles (DDGS) — though more commonly exported from the US than imported — can also enter under this heading. Canada leads import supply, with Brazil and Vietnam also notable sources, reflecting diverse fermentation industries globally.
AI-written summary of the official U.S. Census Bureau trade figures on this page — verify before relying on it.
DDGS derived from grain distilling operations can fall under heading 2303300000 as distilling dregs and waste. However, classification depends on the specific processing method and composition — some DDGS products may be directed to other headings depending on their starch or protein modification. A detailed product specification and, if needed, a CBP binding ruling will confirm the correct classification.
Importers should provide a commercial invoice identifying the source fermentation process (brewing vs. distilling), a certificate of analysis showing moisture, protein, and fiber content, and country-of-origin documentation. FDA may require prior notice for feed ingredients entering human or animal food supply chains, and some states impose additional feed registration requirements.
