FAQ

What work fits NAICS 331110?
  • Production and delivery of primary steel slabs, billets, and ingots meeting specified chemical composition and mill test reports for downstream rolling or forging.
  • Ferroalloy smelting and casting to specified alloy content delivered as chargeable forms for integration into steelmaking operations.
  • Contracted melt-shop production runs with scheduled heats, heat tracking, and lot traceability tied to purchase orders.
  • Supply of primary carbon steel bars, billets, and slabs for further processing by rolling mills, forging shops, or downstream metallurgical operations.
When is NAICS 331110 a weak fit?
  • Rolled steel product manufacturers and metal service centers: missing primary smelting and melting processes; these downstream processors reshape or redistribute purchased steel.
  • Steel fabrication and structural assembly: missing smelting and primary product production; fabrication assembles or cuts finished steel stock into structures.
  • Nonferrous metal smelting (aluminum, copper): missing iron and steel primary smelting and ferroalloy production processes.
What solicitation language points to NAICS 331110?
  • Technical specs requiring chemical composition ranges, heat numbers, and mill test certificates for each lot delivered.
  • Line items specifying tonnage by product form (ingot, slab, billet), scheduled heats, and accepted production lead times.
  • Performance terms referencing melt-shop capacity, heat tracking, metallurgical acceptance testing, and lot-level traceability.
