Gunther Salt Company

Gunther Salt Company, doing business as Gunther Salt Co, a for-profit Subchapter S corporation based in St. Louis, Missouri, supplies bulk and bagged salt products to federal agencies as a prime contractor (100% of recent awards), competing in full-and-open and Total Small Business set-aside categories. The company manufactures and supplies solar salt, rock salt, and evaporated salt for water treatment, road deicing, and specialty applications across the Bureau of Prisons and the Department of Veterans Affairs.

Gunther Salt's customer base concentrates heavily on the Department of Justice Bureau of Prisons and the Department of Veterans Affairs. The top five customer entities account for 88% of combined potential value across 121 prime awards, led by the Federal Correctional Complex Terre Haute (9 awards, $1.1 million combined potential value), the Air Force Materiel Command (3 awards, $1.1 million), the Bureau of Prisons (10 awards, $933 thousand), Veterans Integrated Service Network 10 (7 awards, $902 thousand), and the Medical Center for Federal Prisoners Springfield (14 awards, $776 thousand). Recent awards span Total Small Business and full-and-open designations without consistent set-aside preference.

Gunther Salt holds positions on five indefinite delivery contracts, the largest being an IDC with the Federal Correctional Complex Terre Haute carrying seven task orders and $573 thousand in combined potential value, followed by a Department of Veterans Affairs IDC with five task orders for $388 thousand. In November 2025, the Medical Center for Federal Prisoners Springfield awarded Gunther Salt a single-award indefinite delivery contract for bulk solar salt with a ceiling of $276,390 and a base period running through October 31, 2026, with four option years extending through October 31, 2030. The contract specifies annual requirements of approximately 185 tons of high-purity sodium chloride (greater than 99.5%) delivered in eight shipments. Representative recent work includes a $151,404 purchase order from the Federal Correctional Complex Forrest City (awarded January 26, 2026) for bulk softener salt and bag softener salt through September 30, 2026; a $49,549 delivery order from the Medical Center for Federal Prisoners Springfield for bulk salt supply (January 1, 2026); and a $60,000 purchase order from Federal Correctional Complex Forrest City for bulk water softener salt and bag softener salt under Total Small Business set-aside (October 10, 2024).

Activity has declined in recent years—three awards in 2022 and 2023, two in 2024, one in 2025, and two in 2026—with combined potential value of $5.5 million and $2.5 million in obligations (46% obligated). Only one award faces ultimate completion within the next twenty-four months, carrying $151 thousand in potential value. Gunther Salt operates exclusively as a prime contractor with no subcontract footprint. The vendor maintains active SAM registration since December 2001 and has established long-term delivery relationships with federal prison and VA medical facilities, leveraging an established supply chain and logistics capability to meet high-volume, recurring salt procurement requirements across correctional and healthcare operations.
