UK export controls restrict the transfer of goods or technology, and the provision of technical assistance. The controls apply to the physical movement of goods or the transfer of software, data, technology or know how by any means (including by email and telephone) from the UK to a destination outside of the UK, and, in some cases, inside of the UK where the material is likely to be used outside of the UK.
Where an export falls under one or more of the controls, a licence may be required before any transfer can be made. There is no automatic exemption for academics and researchers.
Failure to obtain an appropriate licence to export controlled goods is a criminal offence.
