Grain storage facilities are places for bulk storage of grains intended for consumption as food or fuel sources, such as corn, wheat, rice, rye, oats, and various raw seeds. This does not include warehouse spaces for storage of packaged seeds or finished grain products. It also does not include seed storage facilities where plant seeds are stored for future cultivation.

The intended use can be food or a fuel source. Raw seeds fall within this usage when held for consumption on that basis.

Seed storage concerns seeds retained for planting. The same crop species can therefore have different storage uses according to the purpose of the held seeds.
