Every expiring NAICS 485111 contract →

Contracts and task orders from USASpending.gov (FPDS) whose period of performance ends within 18 months, valued at $25K or more, excluding IDIQ ceilings and government-owned, contractor-operated facility contracts. Co-terminous orders from the same vendor, agency, NAICS and PSC ending in the same month are grouped. The solicitation date is an estimate (about six months before the contract ends): FedSift does not know whether a follow-on has been posted, so check SAM.gov.

Who counts as small under this code

SBA size standard for NAICS 485111: $29.0M annual receipts.

Each solicitation carries exactly one NAICS code, and that code — not a related one in the same family — decides who counts as small.

One code, chosen by the contracting officer, decides who counts as small. A related code in the same family does not qualify you, and the assignment itself can be appealed to SBA OHA.
