FY2025 federal contract obligations, USAspending.gov
NAICS 561599 obligated $798 million in FY2025 across 354 contract awards, and DHS accounts for $759 million of it. A 95 percent share from one agency is among the most concentrated civilian-led markets we track. DoD follows at $23 million, State at $8 million, Commerce and VA at about $3 million each. Whatever a vendor's commercial travel business looks like, the federal version of this code is a DHS transportation and movement requirement bought at scale.

Competing in this code
37 IDVs against 354 awards, at an average over $2.2 million, describes a very small number of large positions. The $32.5 million size standard is among the higher revenue standards in the support sector, so small business status persists to real scale, but that helps only if there is a competition to enter. Practically, a firm should treat DHS as the market and everything else as incidental. Charter and movement capacity, 24-hour operations, and the ability to document passenger accountability are the evaluated capabilities, and none of them resemble commercial corporate travel management.
NAICS 561599 FAQ
What is the SBA size standard for NAICS 561599?
SBA sets it at $32.5 million in average annual receipts, averaged over your last five completed fiscal years. Come in at or under that and you are small on every NAICS 561599 solicitation, including the set-asides.
Which agencies buy travel arrangement services under NAICS 561599?
FY2025 obligations: DHS ($759 million), DoD ($23 million), State ($8 million), Commerce ($3 million), VA ($3 million). DHS at 95 percent means this code is functionally one agency's requirement, and a strategy built on the other five percent has almost nothing to pursue.
Is NAICS 561599 the right code for corporate travel management?
Not in federal terms. Agencies buy managed travel through the governmentwide travel program, and the $798 million obligated under 561599 in FY2025 is 95 percent DHS transportation and movement work. Commercial travel management credentials do not match what is being evaluated in this code.
What capabilities are actually evaluated in NAICS 561599?
Charter and movement capacity, round-the-clock operations, and documented passenger accountability. With only 37 IDVs and 354 awards at an average over $2.2 million, these are large operational contracts, and the evaluation looks much more like transportation services than like reservation management.
