DDGS (Distillers Dried Grains) by Rail
The co-product of ethanol production — what's left of the corn after fermentation. A protein feed that moves from ethanol plants to feedlots, dairies and export.
| Railcar | Covered hopper (5,200+ cu ft) |
| Typical net load | 95–105 tons per car |
| Bulk density | ~28–34 lb/cu ft |
| Loading constraint | Cubes out (volume-limited) |
| STCC | 20421 — look up related codes in the STCC Finder |
What it's used for
Cattle, dairy, poultry and swine feed rations; export (Mexico is the largest buyer).
How it moves
Lighter than whole grain, so it wants the larger-cube hopper. Steady year-round flow from Corn Belt ethanol plants; Mexico-bound unit trains are common.

Common questions
Can ddgs (distillers dried grains) be shipped by rail?
Yes. DDGS (Distillers Dried Grains) moves regularly on the North American rail network in covered hoppers. Lighter than whole grain, so it wants the larger-cube hopper.
How many tons of ddgs (distillers dried grains) fit in a railcar?
A typical load is 95–105 net tons per car — the car fills up (cubes out) before it reaches its weight limit.
What railcar does ddgs (distillers dried grains) move in?
Covered hopper (5,200+ cu ft). Because the commodity is light for its volume, shippers prefer the largest cubic capacity available.
What is the bulk density of ddgs (distillers dried grains)?
Roughly 28–34 lb per cubic foot, depending on grade and condition.
