Silver Reutilization and Account Maintenance Service

Solicitation # N0025327Q0001

The Naval Undersea Warfare Center Division, Keyport is seeking a contractor for Silver Reutilization and Account Maintenance Services. The primary objective is the refinement of silver-bearing materials recovered from Silver/Zinc and Silver/Chloride batteries to achieve a purity of 99.9%, which will then be used to manufacture new batteries. Annual requirements include the processing of 328,060 troy ounces of high silver content material and 582,421 troy ounces of low silver content material, alongside the maintenance of silver accounts for 439,108 troy ounces. The government will handle the disassembly and categorization of batteries into high-yield and low-yield materials, with the exception of small batteries like AA-sized units. The government intends to award one Indefinite-Delivery Indefinite-Quantity (IDIQ) contract with a five-year ordering period using Lowest Price Technically Acceptable (LPTA) procedures. The contract will be Fixed-Price with Economic Price Adjustment based on the London Bullion Market Association Silver Price index. Performance will take place at the contractor's facility, with a requirement that refined silver be available for transfer within 60 days of receipt of materials. The contractor must maintain up to eight electronic accounts for various Navy programs and provide detailed reporting on materials processed, account balances, and quarterly progress. This is a full and open competition under NAICS code 331492, with the final Request for Quote expected around October 2026.
