FAQ

What work fits NAICS 333998?
  • Manufacture custom mechanical equipment assemblies not covered by a specific machinery code, delivered with as-built drawings, serial numbers, and factory acceptance records.
  • Produce retrofit machinery kits from controlled bills of material, including machined brackets, guarded mechanical assemblies, couplings, labels, and packaged installation hardware.
  • Assemble benchtop or skid-mounted process equipment used for material handling, sample preparation, or equipment testing, with documented run tests before shipment.
  • Small-lot production of replacement machinery subassemblies where the contract requires factory fabrication, assembly, labeling, packaging, and acceptance testing.
When is NAICS 333998 a weak fit?
  • Fluid power pump and motor manufacturing: the primary products are hydraulic or pneumatic pumps, motors, reservoirs, valves, and power units covered by a more specific machinery code.
