What this NAICS covers

NAICS 331492 covers secondary smelting, refining, and alloying operations that recover, melt, and reprocess nonferrous scrap excluding copper and aluminum into refined metal forms, alloys, or master alloys for industrial resale or downstream manufacture.

Federal opportunities under 331492 typically involve processing government-owned or contractor-generated nonferrous scrap into specification-grade ingots or alloys, providing certified assays and material safety documentation, and performing toll-refining, alloy blending, and delivery of finished metal products.

FAQ

What work fits NAICS 331492?
  • Toll-refining contracted scrap lead or zinc into specification-grade ingots with certificate of analysis and lot traceability.
  • Alloy production to a buyer-specified composition, blending feedstock to deliver master alloys or cast billets for downstream metalworking.
  • Reclamation and refining of precious metals and other nonferrous residues from electronic scrap with assay reporting and refined metal delivery.
  • Processing contractor-returned nonferrous components into marketable secondary metal products and supplying documented chain-of-custody and hazardous-waste disposition records.
When is NAICS 331492 a weak fit?
  • Primary nonferrous smelting (primary metal production): missing ore reduction and primary smelting operations, which are outside secondary refining scope.
  • Copper or aluminum primary or secondary processing: copper and aluminum work is explicitly excluded from this NAICS and belongs under separate metal-processing codes.
  • Metal fabrication or machining: production of finished metal parts, machining, casting, or forming is downstream manufacturing, not secondary smelting or alloying.
What solicitation language points to NAICS 331492?
  • Specification requires delivery of ingots, billets, or master alloys with percent composition tolerances and certified assay reports.
  • Scope calls for toll-processing of customer-provided scrap with chain-of-custody, hazardous-waste manifests, and final material disposition documentation.
  • Evaluation criteria request refinery capacity, melting/casting equipment descriptions, and procedures for alloy blending and metallurgical testing.
