FAQ

What work fits NAICS 333120?
  • Producing serial-numbered heavy equipment units to engineering drawings with factory acceptance testing and delivery logistics.
  • Manufacturing and supply of spare parts kits and serialized assemblies with lot traceability and configuration control for sustainment programs.
  • Developing and prototyping modified machine components or new attachments with design iteration and shop testing.
  • Performing production line tooling changes and short production runs to meet updated safety or emissions specifications with documented test results.
When is NAICS 333120 a weak fit?
  • Commercial vehicle body fabrication that focuses on nonpowered bodywork and sheet-metal enclosures without manufacture of powered drive trains or major mechanical systems.
  • Equipment rental, fleet maintenance, and field repair contracts that provide service, overhaul, and spare-part replacement rather than original equipment manufacturing and parts production.
  • Metal fabricators producing structural steel or nonpowered fabricated components without assembly, integration, or testing of powered construction machinery and its subsystems.
What solicitation language points to NAICS 333120?
  • Scope requires factory acceptance test procedures, emissions or safety certification evidence, and delivery of serial-numbered units with parts lists.
  • Solicitation labor categories call out mechanical design engineers, production assemblers, welders, and test technicians for shop-based manufacturing.
  • Evaluation language requests demonstrated production capacity, tooling descriptions, and documentation of manufacturing quality control and lot traceability.
