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.

The list combines Commerce, State and Treasury export-control and sanctions lists. A “no match” result is a name-and-address screen, not an export-compliance determination.

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.
