Will not be imported, re-exported or transferred to be used in the design, development, production, stockpiling, or use of missiles, rocket systems or unmanned air vehicles of any range or payload. “Rocket systems” include, but are not limited to, ballistic missile systems, space launch vehicles, and sounding rockets. “Unmanned air vehicles” include, but are not limited to, cruise missile systems, target drones and reconnaissance drones.
Product and/or replicas ("replicas" refers to items produced abroad on physical examination of the item originally exported, matching it in all critical design and performance parameters) thereof will not be used (either directly or indirectly) in sensitive nuclear end-uses, as follows:
1. Nuclear explosive activities: Nuclear explosive activities, including research on or development, design, manufacture, construction, testing or maintenance of any nuclear explosive device, or components or subsystems of such a device.
2. Unsafeguarded nuclear activities: Activities including research on or development, design, manufacture construction, operation, or maintenance of any nuclear reactor, critical facility, facility for the fabrication of nuclear fuel, facility for the conversion of nuclear material from one chemical form to another, or separate storage installation, where there is no obligation to accept International Atomic Energy Agency (IAEA) safeguards at the relevant facility or installation when it contains any source or special fissionable material (regardless of whether or not it contains such material at the time of export), or where any such obligation is not met.
3. Safeguarded and unsafeguarded nuclear activities: Safeguarded and unsafeguarded nuclear fuel cycle activities, including research on or development, design, manufacture, construction, operation or maintenance of any of the following facilities, or components for such facilities for the:
