Official definition
This U.S. industry comprises establishments primarily engaged in manufacturing truck and bus bodies and cabs and automobile bodies. The products made may be sold separately or may be assembled on purchased chassis and sold as complete vehicles.
NAICS 336211 obligated $310 million in FY2025 across 4,451 contract actions. GSA leads at $136 million, DoD follows at $105 million, DHS at $34 million for border and law enforcement vehicle configuration, EPA at $14 million for mobile laboratory and monitoring vehicles, Interior at $6 million. EPA appearing in a top five is rare and reflects a genuinely specialized upfitting requirement.
What belongs here
Manufacturing truck and bus bodies and cabs and automobile bodies, whether sold separately or assembled onto purchased chassis and sold as complete vehicles. This is the upfitter's code.
- Complete light duty vehicle manufacturing is 336110.
- Heavy duty chassis and complete heavy trucks are 336120.
- Combat platforms built as armored vehicles from the ground up are 336992.
Competing in this code
174 IDVs against 4,451 actions at an average near $70,000 is high-volume configuration work, and it is one of the more accessible vehicle codes for a mid-size manufacturer. The federal buyer wants a chassis it already owns or has ordered turned into a working mission vehicle: law enforcement packages, mobile command and laboratory builds, utility and maintenance bodies. Federal Motor Vehicle Safety Standards compliance on the completed vehicle is the responsibility that trips up shops entering this market, because a final-stage manufacturer certification carries obligations a commercial upfitter may never have formally assumed.
Frequently Asked
NAICS 336211 questions, answered.
What is the SBA size standard for NAICS 336211?
SBA sets it at 1,000 employees, counted as a 24-month average headcount across your company and every affiliate, not revenue. At or under that number you are small on NAICS 336211 solicitations and eligible for the set-asides in this code.
Which agencies buy vehicle bodies and upfitting under NAICS 336211?
FY2025 obligations: GSA ($136 million), DoD ($105 million), DHS ($34 million), EPA ($14 million), Interior ($6 million). EPA's presence is unusual and reflects mobile laboratory and environmental monitoring vehicle builds, which are a small but recurring specialty requirement.
Is vehicle upfitting classified under NAICS 336211?
Yes. The code covers manufacturing bodies and cabs whether sold separately or assembled onto purchased chassis and delivered as complete vehicles. Law enforcement packages, mobile command and laboratory builds, and utility bodies all belong here rather than under a complete vehicle manufacturing code.
What compliance obligation catches upfitters entering federal work?
Final-stage manufacturer certification under the Federal Motor Vehicle Safety Standards. Completing a vehicle on a purchased chassis makes you responsible for certifying the finished product, with the documentation and recall obligations that follow. Commercial upfitters sometimes operate without formally assuming that role, and federal solicitations do not allow the ambiguity.
