Deemed export
A deemed export is the release of controlled technology or source code to a foreign person within the United States — treated, or "deemed", to be an export to that person’s country of nationality even though nothing crosses a border.
The step most authors miss
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.
How a deemed export happens
Under the EAR and ITAR, an "export" includes releasing controlled technology or source code to a foreign person. When that release happens inside the United States, it is "deemed" to be an export to the foreign person’s most recent country of citizenship or permanent residency. Release can occur through demonstrations, visual inspection, oral exchanges, or giving access to equipment, data or systems. No shipment and no border crossing is required — the transfer of knowledge itself is the controlled event.
Why it matters on campus
Universities routinely host foreign nationals as graduate students, postdoctoral researchers and visiting scientists. Where a project involves controlled technology, granting those individuals access can be a deemed export needing authorisation. The fundamental research exclusion shelters most open academic work from this rule, but it can fall away if the research carries publication or access restrictions, uses controlled physical items, or is governed by proprietary contract terms — situations where deemed-export analysis becomes essential.
Managing deemed-export risk
Institutions typically address deemed exports through classification of the technology involved, screening of personnel, and, where needed, a technology control plan that limits access to authorised persons. A "foreign person" generally means anyone who is not a US citizen, lawful permanent resident or protected individual. Determining whether a licence is required depends on the technology’s classification and the individual’s country of nationality, and is usually handled with an institutional export-control office.
Key facts
At a glance
- Definition: release of controlled technology/source code to a foreign person in the US
- Deemed to be: an export to the person’s country of nationality
- Triggers: visual access, oral exchange, training, data or equipment access
- Foreign person: not a US citizen, permanent resident or protected individual
- Common in: labs hosting foreign students, postdocs and visiting scholars
- Key relief: fundamental research exclusion (when its conditions are met)
Common misconceptions
What people often get wrong
Often heard: A deemed export only happens if controlled data is emailed or shipped overseas.
Actually: A deemed export occurs when controlled technology is released to a foreign person within the country — including through conversation, demonstration or lab access. Nothing has to be sent abroad for it to count as an export.
Often heard: Any interaction with a foreign researcher is a deemed export.
Actually: Only the release of controlled technology or source code triggers the rule. Sharing fundamental research results, published information or non-controlled material is not a deemed export.
Often heard: A foreign person’s visa status is what determines the deemed-export licence.
Actually: The relevant factor is the individual’s country of citizenship or permanent residency together with the technology’s classification, not the type of visa held.
