FAQ

What work fits NAICS 336120?
  • Full production contracts for heavy-duty cargo trucks delivered in production runs with factory-installed drivetrains, frames, and cabs meeting vehicle-level acceptance tests.

  • Contracts that include assembly line acceptance criteria, production scheduling, and serial-numbered warranty and parts support from the original equipment manufacturer.
