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.
No confirmed match on the Consolidated Screening List (screened Nov 10, 2026).
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.
