More generally speaking, dual-use can also refer to any goods or technology which can satisfy more than one goal at any given time. Thus, expensive technologies originally benefitting only military purposes would in the future also be used to serve civilian commercial interests if they were not otherwise engaged, such as the

Those who seek to develop ballistic missiles may claim that their rockets are for peaceful purposes; for example, for commercial satellite launching or
scientific purposes. However, even genuinely peaceful rockets may be converted into weapons and provide the technological basis to do so.
Within peaceful rocket programs, different peaceful applications can be seen as having parallel military roles. For example, the return of scientific payloads safely to earth from orbit would indicate
re-entry vehicle capability and demonstrating the ability to launch multiple satellites with a single launch vehicle can be seen in a military context as having the potential to deploy
multiple independently targetable reentry vehicles.

. When this happens a nuclear power program can become a route leading to the
atomic bomb or a public annex to a secret bomb program. The crisis over
Iran's nuclear activities is a case in point.
Many UN and US agencies warn that building more nuclear reactors unavoidably increases
nuclear proliferation risks. A fundamental goal for American and global security is to minimize the proliferation risks associated with the expansion of nuclear power. If this development is "poorly managed or efforts to contain risks are unsuccessful, the nuclear future will be dangerous".
[ For nuclear power programs to be developed and managed safely and securely, it is important that countries have domestic “ good governance” characteristics that will encourage proper nuclear operations and management:][
]
These characteristics include low degrees of corruption (to avoid officials selling materials and technology for their own personal gain as occurred with the A.Q. Khan smuggling network in Pakistan), high degrees of political stability (defined by the World Bank as “likelihood that the government will be destabilized or overthrown by unconstitutional or violent means, including motivated violence and terrorism”), high governmental effectiveness scores (a World Bank aggregate measure of “the quality of the civil service and the degree of its independence from political pressures ndthe quality of policy formulation and implementation”), and a strong degree of regulatory competence.[

s were among the suspects. The challenge remains to maintain security without impairing the contributions to progress afforded by research.
Reports from the project on building a sustainable culture in dual-use bioethics suggest that, as a result of perceived changes in both science and security over the past decade, several states and multilateral bodies have underlined the importance of making life scientists aware of concerns over dual-use and the legal obligations underpinning the prevention of biological weapons. One of the key mechanisms that have been identified to achieve this is through the education of life science students, with the objective of building what has been termed a “culture of responsibility”.
At the 2008 Meeting of States Parties to the Biological and Toxin Weapons Convention (BTWC), it was agreed by consensus that: States Parties recognized the importance of ensuring that those working in the biological sciences are aware of their obligations under the convention and relevant national legislation and guidelines...States Parties noted that formal requirements for seminars, modules or courses, including possible mandatory components, in relevant scientific and engineering training programmes and continuing professional education could assist in raising awareness and in implementing the convention.

education has become more important. Unfortunately, both the policy and academic literature show that life scientists across the globe are frequently uninformed or underinformed about biosecurity, dual-use, the BTWC and national legislation outlawing biological weapons. Moreover, despite numerous declarations by states and multilateral organisations, the extent to which statements at the international level have trickled down to multifaceted activity at the level of scientists remains limited.
The US federal government (USG) developed several policy documents on DURC. In May 2024, the White House published the "United States Government Policy for Oversight of Dual Use Research of Concern and Pathogens with Enhanced Pandemic Potential", "a unified federal oversight framework for conducting and managing certain types of federally funded life sciences research on biological agents and toxins." The policy superseded several prior documents, published in 2012, 2014, and 2017, and it follows the directives established by the 2022 National Biodefense Strategy and Implementation Plan.

In the United States, civilians are free to buy and sell American-made night vision and thermal systems, such as those manufactured by defense contractors Harris, L3 Insight, and FLIR Systems, with very few restrictions. However, American night vision owners may not bring the equipment out of the country, sell it internationally, or even invite non-citizens to examine the technology, per International Traffic in Arms Regulations.
Export of American image intensifiers is selectively permitted under license by the United States Department of Commerce and the State Department. Contributing factors in acquiring a license include diplomatic relations with the destination country, number of pieces to be sold, and the relative quality of the equipment itself, expressed using a Figure Of Merit (FOM) score calculated from several key performance characteristics.
Competing international manufacturers (European defense contractor Exosens Group, Japanese scientific instrument giant Hamamatsu Photonics, and Russian state-financed laboratory JSC Katod) have entered the American market through licensed importers. In spite of their foreign origin, re-export of these components outside of the United States is restricted similarly to domestic components.

Other technologies
In addition to obvious dual-use technologies there are some less obvious ones, in that many erstwhile peaceful technologies can be used in weapons.

within the real world. However, it was revealed Microsoft made a 479 million dollar deal with the U.S. government. This contract would have Microsoft create and supply the U.S. Army a separate version of the HoloLens smart glasses called the Integrated Visual Augmentation System (IVAS). The IVAS would be used to train soldiers, as well as field medics with battlefield experience within a virtual environment. This version of the HoloLens allowed the soldiers to have a virtual map of their current environment, friendly units' locations, and much more. An anonymous Microsoft employee published an open letter demanding that Microsoft terminate the IVAS contract. Microsoft president Brad Smith had previously made a public blog post outlining the company's stance on "how technology companies should work with the government, and specifically whether companies should supply digital technology to the military."
Control
Most industrial countries have export controls on certain types of designated dual-use technologies, and they are required by a number of treaties as well. These controls restrict the export of certain commodities and technologies without the permission of the government.
In the context of sanctions regimes, dual-use can be construed broadly because there are few things which do not have the potential for both military and civilian uses.
United States
The principal agency for investigating violations of dual-use export controls in the United States is the Bureau of Industry and Security (BIS) Office of Export Enforcement (OEE). Interagency coordination of export control cases are conducted through the Export Enforcement Coordination Center (E2C2). The International Traffic in Arms Regulations is the US regime that the BIS OEE enforces.
