A research office preparing to send a visiting-scholar invitation letter runs the prospective scholar's name through the CSL as part of its standard onboarding checklist before finalizing the invitation.

A sponsored programs office vetting a proposed foreign subrecipient on an international collaborative grant screens the subrecipient institution's name against the CSL before executing the subaward agreement.
Counter-examples
Looks similar, but isn't
- Not an instance
A check of the federal procurement debarment/suspension exclusion list on SAM.gov is not a CSL screen -- SAM.gov Exclusions covers eligibility for federal awards and contracts under 2 CFR Part 180, a separate purpose from the CSL's export/sanctions restricted-party lists, even though institutions often run both checks together.
Editorial commentary
The Consolidated Screening List (CSL) is a single, merged database maintained by the US Department of Commerce (via trade.gov) that combines the restricted- and denied-party lists published separately by the Departments of Commerce, State, and the Treasury. Instead of checking each agency’s list one at a time, an institution can screen a name once against the CSL and get a match against every contributing list simultaneously.
What lists the CSL consolidates
As described on trade.gov, the CSL pulls together lists from three federal departments:
- Department of Commerce, Bureau of Industry and Security (BIS): the Denied Persons List, Entity List, Unverified List, and Military End-User List.
- Department of State: the AECA Debarred List (parties barred from participating in defense-article exports administered by the Directorate of Defense Trade Controls) and the Nonproliferation Sanctions list.
- Department of the Treasury, Office of Foreign Assets Control (OFAC): the Specially Designated Nationals and Blocked Persons (SDN) List plus OFAC’s other sanctions-related lists (for example the Foreign Sanctions Evaders List and Sectoral Sanctions Identifications List).
Each list has its own legal basis and consequence for a match — an EAR licensing requirement, an ITAR debarment, or an OFAC sanctions prohibition are not interchangeable — but the CSL lets an institution run one search and then determine, list by list, which regime a hit actually falls under. Trade.gov states the underlying source lists are refreshed daily (5:00 a.m. ET/EDT).
Why research institutions use it
University export control, sponsored programs, and research security offices use the CSL as a due-diligence screening tool before entering into activities that could put the institution in an unauthorized transaction with a restricted party. Typical screening points include:
- Onboarding a foreign national visiting scholar, postdoc, or graduate student who will access controlled equipment, software, or technical data.
- Vetting a prospective international collaborator, subrecipient, or foreign institution before executing a subaward, material transfer agreement, or research collaboration agreement.
- Screening a vendor or shipping destination before exporting controlled equipment or technical data abroad.
- Confirming a foreign sponsor, gift source, or contracting party isn’t a sanctioned or denied party, alongside the institution’s broader foreign-influence and research-security disclosure obligations.
The CSL is searchable directly at trade.gov/consolidated-screening-list and via the CSL Search tool and a public API (data.commerce.gov), which is how most institutional screening software and denied-party screening vendors pull their underlying data rather than building separate feeds from each agency.
How it relates to other export/sanctions tools
The CSL is a consolidation layer, not a separate legal regime — a CSL match still has to be traced back to the source list and the regulation behind it:
- A hit against a BIS list ties back to the Export Administration Regulations (EAR) and the Commerce Control List.
- A hit against the AECA Debarred List ties back to the International Traffic in Arms Regulations (ITAR).
- A hit against an OFAC list ties back to the specific sanctions program OFAC is enforcing (country-based or list-based).
The CSL does not include the federal procurement debarment/suspension list maintained on SAM.gov — that’s a separate exclusion mechanism under 2 CFR Part 180 governing eligibility for federal awards and contracts, not export/sanctions restricted-party status. A thorough pre-award or pre-collaboration due-diligence check typically screens both the CSL and SAM.gov Exclusions, since they answer different questions.
Examples
A research office preparing to send a visiting-scholar invitation letter runs the prospective scholar’s name through the CSL as part of its standard onboarding checklist; a clean screen (no match on any contributing list) clears that step of the review, though export control classification of the specific research activity is still assessed separately.
A sponsored programs office vetting a proposed foreign subrecipient on an international collaborative grant screens the subrecipient institution’s name against the CSL before executing the subaward agreement, as part of the same due-diligence pass that also checks SAM.gov exclusions and, where applicable, restricted-party guidance tied to research security disclosure requirements.
What it is not
A clean CSL screen is not, by itself, a determination that a research activity or piece of equipment is free of export control obligations. The CSL only tells an institution whether a specific party appears on a restricted-party list; whether a given item, software, or technical data is controlled at all is a separate classification question governed by the EAR and ITAR, and whether a funding source or foreign sponsor triggers a research-security or foreign-influence disclosure obligation is a separate compliance question again.
