If I operate a feed mill that manufactures, warehouses, and distributes animal food in packaged form and/or in bulk, does my facility have to register?

Yes. The feed mill would be required to register because the feed mill manufacturers, processes,
packs, or holds animal food for consumption in the United States, unless the feed mill meets one
of the exemptions in 21 CFR 1.226 (see also sections II.B.1 Farms and II.B.2 Retail Food
Establishments).
