HS Code 2303.30 – Brewing or distilling dregs and waste; whether or not in the form of pellets
HS code 2303.30 is the 6-digit subheading for brewing or distilling dregs and waste, whether or not in the form of pellets. It is used for brewers' spent grains, distillers' dried grains with solubles (DDGS), spent yeast, malt sprouts and brewery waste.
What HS 2303.30 covers
This HS code encompasses the various solid and semi-solid by-products generated during the brewing of beer and the distillation of spirits. These materials, such as spent grains, yeast, and other residues, are highly valued in the animal feed industry, especially for cattle, due to their rich protein and fiber content. They can also find applications in biogas production or as organic fertilizers. International trade involves breweries and distilleries selling their waste products to feed manufacturers or brokers, often in bulk or pelletized form to reduce transport costs. The market is influenced by the scale of beverage production and the demand from the livestock sector.

How these figures are built
109 countries reported 2025 trade to UN Comtrade in HS 2022, and their own totals are used. Countries marked * did not, so their figures add up what other countries recorded trading with them, and their exports are valued at buyers' CIF prices. Those estimates miss trade with other non-reporting countries, so they can be low, and a non-reporting country can rank higher than shown or be missing from the list. World totals add both and leave out trade between two non-reporting countries. Figures are in current US dollars; reported imports are mostly valued CIF and exports FOB, and exports include re-exports. The UN Comtrade links show the underlying records; they can also list a few reporters left out here (regional groups and older HS editions).
