Denied party screening
Denied party screening (also called restricted party screening) is the practice of checking the parties to a transaction against US government prohibited- and restricted-party lists before exporting, shipping or collaborating.

Doing CRediT right? Don’t stop at the statement.
A CRediT statement credits you inside one paper. The recognition CRediT was built for happens when those roles are tied to you, persistently. Sign in with your ORCID — free — and claim your CRediT contributions on casrai.org, the home of the standard. They become a verified, portable part of your identity, not a line that disappears into one PDF.
Free: claim your contributions, then export a journal-ready CRediT statement, schema.org structured data, JATS XML, CSV or BibTeX — and preview your public profile. A membership publishes that profile publicly and verifies the journals you serve.
What screening checks
Denied party screening compares the names and details of transaction parties — buyers, recipients, intermediaries, collaborators and end users — against published US government lists of prohibited and restricted parties. The aim is to identify, before an export, shipment or engagement, anyone with whom dealings are barred or restricted. Screening commonly extends beyond a single name to related individuals, organisations and addresses, because restricted parties can appear under aliases or affiliated entities.
The main US lists
Several lists are relevant. The Bureau of Industry and Security maintains the Denied Persons List, the Entity List and the Unverified List. The Department of State maintains debarment and nonproliferation lists. The Office of Foreign Assets Control maintains the Specially Designated Nationals (SDN) list and other sanctions lists. The US government consolidates many of these into a single searchable Consolidated Screening List, which supports a one-step check across multiple agencies’ lists.
Screening in the research context
Universities apply screening to international shipments, foreign collaborations, visiting scholars, vendors and conference or training participants. A match — or a near match — typically triggers further review rather than an automatic stop, because list entries must be confirmed against the actual party. Because list contents change frequently, screening is treated as a recurring control, often run at the start of an engagement and re-run as parties or circumstances change, and coordinated with an institutional export-control office.

Common misconceptions
What people often get wrong
Often heard: Screening is only needed for physical shipments leaving the country.
Actually: Screening applies to many dealings — collaborations, visitors, vendors and intangible technology transfers — not just shipments. Sanctions and end-user controls can bar transactions regardless of whether goods physically move.
Often heard: A name match on a list automatically means the transaction is prohibited.
Actually: A potential match triggers review to confirm whether the listed party is in fact the party to the transaction. Many initial matches are false positives that resolve once details such as date of birth or address are compared.
Often heard: Screening once at the start of a relationship is sufficient.
Actually: Government lists change frequently, so screening is generally treated as an ongoing control, re-run when parties, products or circumstances change rather than performed only once.
