Fundamental research exclusion
The fundamental research exclusion is the principle — rooted in National Security Decision Directive 189 (1985) — that basic and applied research ordinarily published and broadly shared in the academic community is not subject to US export controls.
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.
Origin in NSDD-189
The exclusion traces to National Security Decision Directive 189, issued in 1985, which established as US policy that the products of fundamental research should remain unrestricted to the maximum extent possible, and that where national security requires control, the mechanism should be classification rather than restriction of open publication. Both the EAR and the ITAR carry forward this principle, treating information arising from fundamental research as outside the controlled "technology" they regulate.
What counts as fundamental research
Fundamental research is generally defined as basic and applied research in science and engineering, the results of which are ordinarily published and broadly shared within the scientific community. The defining feature is openness: there are no restrictions on publication and no limits on who may participate or access the results. This is what separates fundamental research from proprietary or government-restricted projects, where access and dissemination are deliberately controlled.
When the exclusion is lost
The exclusion shelters information, not items. It does not extend to controlled physical equipment, materials or encrypted software, which remain subject to the rules regardless of the research context. It can also fall away when a sponsor imposes prepublication approval or restrictions on foreign-national participation, when the work is subject to ITAR-controlled defence articles, or when proprietary contract terms limit disclosure. Once any such restriction is accepted, the protected status of the resulting information may no longer apply.
Key facts
At a glance
- Definition: openly published basic/applied research is outside export controls
- Source: National Security Decision Directive 189 (NSDD-189, 1985)
- Defining feature: no publication or access restrictions
- Covers: information and research results, not physical items
- Reaffirmed: national policy across successive administrations
- Lost when: publication limits, controlled items or proprietary terms apply
Common misconceptions
What people often get wrong
Often heard: The fundamental research exclusion protects all university research from export controls.
Actually: It protects only information arising from research that is ordinarily published and openly shared. Controlled physical items, restricted-access projects and work with publication limits remain subject to the controls.
Often heard: The exclusion covers the equipment and materials used in the research.
Actually: The exclusion applies to information and results, not tangible items. Controlled instruments, samples, software and technology stay regulated even when used in otherwise fundamental research.
Often heard: Accepting a publication-review clause has no effect on the exclusion.
Actually: Sponsor restrictions on publication or on foreign-national participation can remove the research from the exclusion, because openness is the condition on which the protection depends.
