FAQ

What work fits NAICS 335991?
  • Supply machined graphite seals, bushings, or bearings to drawing tolerances with certified density and dimensional inspection reports.
  • Manufacture carbon electrodes with specified purity, geometry, and dimensional tolerances for industrial electrochemical or high-temperature applications.
  • Produce molded graphite crucibles, tooling components, or fixtures with documented thermal properties and material certifications.
  • Assemble and deliver carbon brush assemblies with specified electrical contact characteristics and final inspection for serialized motor hardware.
When is NAICS 335991 a weak fit?
  • Metal machining and fabrication operations that produce metal parts but do not process or machine carbon or graphite materials into finished components.
  • Raw carbon or graphite material production and powder processing that supply base materials without producing finished graphite products or machined components.
  • Ceramic or refractory product manufacturing that shapes non-carbon high-temperature materials rather than producing carbon or graphite components and electrodes.
What solicitation language points to NAICS 335991?
  • Engineering drawings and material callouts specifying graphite grade, density, thermal conductivity, or electrical resistivity and tight dimensional tolerances.
  • Contract requirements for material certification, lot traceability, dimensional inspection reports, and handling instructions for brittle carbon parts.
  • Staffing or deliverable requirements naming graphite machinists, bonders, or heat-treatment steps and packaging protocols for fragile, serialized components.
