Exclusions & screening

Exclusions about SAM.gov exclusionsScreening list about the Consolidated Screening List
Checks a prime runs before teaming: SAM.gov exclusions (debarment and suspension) and the government's Consolidated Screening List for export and sanctions lists.

SAM.gov exclusions

Not yet checked against SAM.gov exclusions.

Search exclusions on SAM.gov (opens in a new tab)

Agencies generally may not award to excluded parties, and primes may not subcontract with them above the threshold in FAR 52.209-6 (except COTS items) without a compelling reason reported to the contracting officer (FAR 9.405, 9.405-2). Some exclusion types apply only to specific programs: read the record on SAM.gov.

Consolidated Screening List

No confirmed match on the Consolidated Screening List (screened Nov 13, 2026).

Corporate hierarchy

Affiliation & size about affiliation and size
Immediate parent and highest-level owner as reported in SAM.gov.

No parent entity reported in SAM.gov.

SBA counts affiliates when it determines whether a business is small (13 CFR 121.103), so a parent’s size can matter for set-aside work.
