NAICS 336211

Overview

The North American Industry Classification System (NAICS) is the federal standard for organizing business establishments to support the collection, analysis, and publication of statistics about the U.S. economy. Established by the Office of Management and Budget and adopted in 1997 to replace SIC, NAICS was jointly developed by the U.S. Economic Classification Policy Committee, Statistics Canada, and Mexico’s INEGI; the current statistical vintage used for Economic Census publications is 2022. ¹

NAICS 336211 — Motor Vehicle Body Manufacturing — covers establishments primarily engaged in making truck and bus bodies and cabs and automobile bodies. These products may be sold separately or assembled on purchased chassis and sold as complete vehicles. Cross-references distinguish heavy duty truck assembly, light vehicle assembly, and certain customization/repair activities that fall under other NAICS industries. ²

What this NAICS covers

• Manufacturing truck bodies and cabs for highway use (e.g., box, flatbed, dump, tanker, refuse, emergency). ²
• Manufacturing bus bodies and cabs (transit, school, coach) for mounting on purchased chassis. ²
• Manufacturing automobile bodies (including specialized bodies and shells) sold separately or on purchased chassis. ²
• Assembling complete vehicles by mounting manufactured bodies onto purchased chassis. ²
• Producing slide-in camper units and pickup canopies/caps/covers categorized under motor vehicle body manufacturing. ²
• Manufacturing parts integral to bodies and cabs when performed by body manufacturers as part of body production. ²

Frequently asked questions

• What products and activities are included under NAICS 336211?

  Establishments manufacture truck and bus bodies and cabs and automobile bodies, which may be sold as standalone bodies or mounted on purchased chassis to create complete vehicles. Examples include box, tanker, refuse, dump, fire/emergency, and school or transit bus bodies. ²

• How is NAICS 336211 different from NAICS 336212?

  336211 covers motor vehicle bodies and cabs for trucks, buses, and automobiles, while 336212 covers truck trailers, trailer chassis, and detachable bodies for trailers. The core distinction is bodies for powered vehicles versus bodies/chassis for towable trailers. ²

• What is the SBA small business size standard for NAICS 336211?

  SBA sets a 1,000-employee threshold for this industry. This employee-based size standard determines eligibility for small business programs, set-asides, and subcontracting credit under federal procurement rules and is effective for solicitations issued on or after March 17, 2023. ³

• Which PSC codes commonly align with motor vehicle body buys?

  Common PSC alignments include 2310 (Passenger Motor Vehicles), 2320 (Trucks and Truck Tractors), and 2510 (Vehicular Cab/Body/Frame Structural Components), as indicated in DoD’s Coordinated Acquisition listings. ⁴

• Does NAICS 336211 include custom van conversions?

  No. One-off, customer-specific interior conversions are treated as repair/customization services under NAICS 81112. Production-line motor homes and certain trailers fall under NAICS 336213 and NAICS 336214, respectively, rather than motor vehicle body manufacturing. ²
