Sodium Tungstate Combined Synopsis/Solicitation

The Defense Logistics Agency (DLA) is conducting a sole-source acquisition for an Indefinite Delivery, Indefinite Quantity (IDIQ) contract to procure sodium tungstate dihydrate, a critical precursor material for tungsten production used in Department of Defense parts manufacturing. DLA Strategic Materials is seeking approximately 100,000 kilograms of sodium tungstate over a five-year ordering period, with estimated annual quantities of 20,000 kilograms per year. The procurement includes two contract line items: sodium tungstate delivery and third-party testing services. Key requirements include delivery of material meeting strict chemical specifications (minimum 65% WO3 and 15% sodium content) packaged in UN 1A2 compliant 55-gallon steel drums, with all sampling, production, and testing activities occurring within the Continental United States and performed by an ISO 17025-certified independent laboratory. Evaluation will be based solely on technical acceptability, with the government awarding to a responsible offeror whose proposal meets minimum requirements and conforms to all technical requirements of the Statement of Work. Vendors must submit questions by March 3, 2026 at 5:00 PM EST, and proposals are due by March 11, 2026 at 5:00 PM EST, with all submissions to be made electronically to Adam Steele and Mitchell Hatfield at the DLA.

This procurement is a sole-source acquisition with no set-aside designation, justified under FAR 6.302-3(a)(2)(i) to maintain domestic production capabilities for critical supplies. The incumbent contractor is Tungco, Incorporated (CAGE: 6XF87), identified through market research as the only domestic secondary producer capable of manufacturing sodium tungstate from reclaimed scrap material; Tungco previously received a DLA contract from August 2024 to August 2025 to establish domestic secondary production capabilities. The estimated contract value ranges from a guaranteed minimum of $1,000,000 to a maximum of $50,000,000 over the five-year period, with firm-fixed pricing on a per-kilogram basis using three tiered quantity ranges. Delivery must be completed within 36 months of each delivery order issuance to one of three DLA Strategic Materials Depots: Scotia Depot in Scotia, New York; Hawthorne Army Depot in Hawthorne, Nevada; or Hammond Depot in Hammond, Indiana, with the place of performance identified as Columbus, Ohio 43215. The contractor bears all transportation costs on a carrier and insurance paid-to (CIP) basis, and material rejection provisions allow for replacement at no cost to the government within 90 calendar days of rejection notification.
