FY2025 federal contract obligations, USAspending.gov
NAICS 336212 obligated $1.9 billion in FY2025 across 625 contract actions, an average of $3.1 million each. DoD is $1.89 billion, or 97 percent. GSA follows at $38 million, DHS and Interior at about $3 million each. Award size is the tell here: commercial trailer sales do not run at $3.1 million per action, and these are military transport and load handling system programs delivered in multi-year quantities.

Competing in this code
46 IDVs against 625 actions means the money moves through a small number of production programs. Entry is not through pricing a commercial trailer competitively; it is through qualifying a design against military transportability, tie-down, and environmental requirements, then delivering at rate. The 1,000-employee size standard admits most trailer manufacturers as small, so set-asides are available, but a first-time offeror without a first article test history against a comparable military specification will struggle on technical evaluation regardless of price.
Frequently Asked
NAICS 336212 questions, answered.
What is the SBA size standard for NAICS 336212?
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 336212 solicitations and eligible for the set-asides in this code.
Which agencies buy trailers under NAICS 336212?
FY2025 obligations: DoD ($1.9 billion), GSA ($38 million), DHS ($3 million), Interior ($3 million), NASA ($1 million). At 97 percent DoD and $3.1 million per action, this code is military transport and load handling programs, not commercial trailer procurement.
Why do NAICS 336212 awards average over $3 million?
Because the code is dominated by military trailer and load handling system programs bought in multi-year production quantities, not by individual commercial trailer sales. 625 actions carried $1.9 billion in FY2025 across just 46 IDVs, which is a small number of large production positions.
What does a commercial trailer manufacturer need to compete here?
A design qualified against military transportability, tie-down, and environmental requirements, plus first article test history on something comparable. The 1,000-employee size standard makes set-asides available, but technical evaluation turns on qualification evidence that a purely commercial builder has never had to generate.
