Is the North Dakota Mill and Elevator Association the only state-owned milling facility in the United States?

Yes.

The North Dakota Mill and Elevator Association is the only state-owned milling facility in the United States. State records describe it as the nation’s sole state-run flour mill, and no other state appears to operate a comparable milling enterprise.

Established in 1922 to support wheat farmers and stabilize grain markets, the mill remains governed by the North Dakota Industrial Commission and functions as a state-owned business that returns its profits to the general fund.

Historical documents from the State Archives outline the original purpose of the mill, noting that it was created after farmers pushed for protections from unfair grain handling practices.

The facility has since grown into one of the largest flour mills in the country, operating without state subsidies.

Reviews of federal and state economic records show no other state-level milling operation with similar ownership, structure or commercial scale.
