What is Controlled?
There may be several reasons why a specific item or technology is brought into focus and therefore requires a special licence in order to be exported - known as an export authorisation.
An item may take the form of specific goods, but also for example services (technical assistance) or electronic transfers. The function and potential use of the item may be decisive for whether you need to apply for an export authorisation.
If in doubt, it is always possible to obtain advice and guidance.
