FAQ

What work fits NAICS 335312?
  • Production and delivery of generator sets with factory acceptance test reports, calibration certificates, and parts lists for depot spares.
  • Manufacture of propulsion and auxiliary motors with specified performance curves, vibration test results, and mechanical integration drawings.
  • Supply of replacement motor end items with serial-numbered traceability, first article inspection, and packaging for inventory stocking.
  • Prototype development transitioning to limited production runs with documented test procedures, engineering change notices, and build records.
When is NAICS 335312 a weak fit?
  • Field repair and depot maintenance contracts where the primary deliverable is on-site repair labor and recurring service rather than factory-finished equipment delivery.
  • Control electronics or motor-drive system procurements when the requirement is for electronic control assemblies and embedded software rather than the motor or generator hardware itself.
  • Structural steel fabrication or site electrical distribution installations where work is construction and installation rather than factory manufacturing of rotating electrical machines.
What solicitation language points to NAICS 335312?
  • Line items require factory acceptance testing with specified performance curves, insulation resistance, and vibration limits as deliverables.
  • Procurement includes first article inspection, serial-numbered part delivery, and production lot build records in the contract deliverables.
  • Evaluation criteria reference manufacturing lead time, production capacity, and documented quality control procedures for motor/generator production.
