The nationality of an exhibitor is determined by the address he uses in order to enter into a contractual relationship with the exhibition organiser.
If the invoice address and the address of the exhibitor who is registering differ from one another then the address of the recipient of services shall apply.
If the address used for entering into a contractual relationship and the nationality of an exhibitor do not coincide then a note in writing from the exhibitor declaring his nationality can be accepted.
