Dual-use items
Dual-use items are goods, software and technology that have both legitimate civilian applications and potential military or proliferation uses — the category of items controlled by the US Export Administration Regulations.

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 makes an item dual-use
An item is "dual-use" when it has a genuine commercial or scientific purpose but could also contribute to military capability or to the proliferation of weapons. The concept captures the reality that the same technology — a high-speed camera, a precision machine tool, strong encryption, a particular biological agent — can serve a research laboratory and a weapons programme alike. Dual-use controls aim to allow legitimate trade and science while limiting transfers that could aid hostile military or proliferation activity.
How dual-use items are controlled
In the United States, dual-use items are regulated under the EAR and enumerated on the Commerce Control List, where each entry carries an ECCN and stated reasons for control such as national security or missile technology. Many dual-use controls originate in multilateral export-control regimes — the Wassenaar Arrangement, the Nuclear Suppliers Group, the Australia Group and the Missile Technology Control Regime — which coordinate control lists among participating countries.
Dual-use items in research
Research institutions encounter dual-use items in instrumentation, computing, materials science, chemistry and the life sciences. Whether a licence is required depends on the item’s classification, its destination, the recipient and the intended end use. The fundamental research exclusion shelters openly published research information, but it does not cover the dual-use physical items or controlled software themselves, which is why equipment purchases, shipments and foreign collaborations are common points for classification review.

Common misconceptions
What people often get wrong
Often heard: Dual-use means an item is only loosely controlled and rarely needs a licence.
Actually: Dual-use describes the item’s nature, not the strength of its controls. Many dual-use items require licences for sensitive destinations or end uses; the requirement depends on classification, destination, end user and end use.
Often heard: Dual-use items are controlled under the ITAR.
Actually: Dual-use items are controlled under the EAR by the Bureau of Industry and Security. The ITAR control defence articles and services designed for military application, which are a separate category.
Often heard: Only finished products can be dual-use.
Actually: Software, source code, materials and intangible technology can all be dual-use. The category is defined by capability and potential application, not by whether the item is a finished good.
