What this NAICS covers

NAICS 331410 covers smelting and refining of nonferrous metals such as copper, lead, zinc, nickel, and precious metals, including processing ore, concentrates, and scrap into refined metal ingots, cathodes, and intermediate alloys for downstream manufacturers.

Federal opportunities under 331410 typically involve procuring production of specified refined nonferrous metals or contracting toll-refining services that deliver certified ingots or alloys, including factory testing, metallurgical quality records, sampling, and documented chain-of-custody for government use.

FAQ

What work fits NAICS 331410?
  • Toll-refining of supplied ore concentrates into refined copper, lead, or zinc metal with assay certificates and chain-of-custody documentation.
  • Production and delivery of refined nonferrous metal ingots or billets meeting specified chemical composition and impurity tolerances with acceptance sampling.
  • Reclamation and metallurgical refining of scrap nonferrous metal into market-grade refined metal with pollution control and waste disposition records.
  • Processing concentrates to produce refined base metal products with emissions monitoring, slag handling, and documented quality control testing.
When is NAICS 331410 a weak fit?
  • Metal fabrication and machining: work centers on shaping, machining, casting, or finishing fabricated parts where metallurgical smelting and primary refining are not performed.
  • Aluminum smelting and refining: contract specifically targets aluminum production processes which are excluded from this classification.
  • Scrap brokerage and mechanical recycling: scope limited to collection, mechanical sorting, or brokerage of scrap without thermal smelting, refining, or metallurgical processing.
What solicitation language points to NAICS 331410?
  • Requirements demand lot-level assay certificates, chemical composition limits, and acceptance testing protocols for delivered metal lots.
  • Solicitation includes emissions permit compliance, stack testing results, and environmental control system monitoring as mandatory deliverables.
  • Contract documents specify acceptance by weight and specified chemical composition with onsite or third-party metallurgical testing for lot acceptance.
