Corn is by far the largest component of global coarse-grain trade, accounting for about three-quarters of total volume in recent years. (Coarse grains make up a common trade category that includes corn, sorghum, barley, oats, and rye.) Most of the corn that is traded is used for feed; smaller amounts are traded for industrial and food uses. Processed-corn products and byproducts including corn meal, flour, sweeteners, and corn gluten feed are also traded, but are not included in this discussion of corn trade.
