Artikel 13

1. Unless otherwise provided by the Acts of the Union, only designated operators shall use the Union’s forms and documentation for the operation of postal services and exchange of postal items in accordance with the Acts of the Union.
2. Designated operators may use the Union’s forms and documentation for the operation of extraterritorial offices of exchange (ETOEs), as well as international mail processing centres (IMPCs) established by designated operators outside their respective national territory, as further defined in paragraph 6, in order to facilitate the operation of the aforementioned postal services and exchange of postal items.
3. The exercise of the possibility outlined in paragraph 2 shall be subject to the national legislation or policy of the member country or territory in which the ETOE or IMPC is established. In this regard, and without prejudice to the designation obligations contained in article 2, designated operators shall guarantee the continued fulfilment of their obligations under the Convention and be fully responsible for all their relations with other designated operators and with the International Bureau.
4. The requirement set forth in paragraph 3 shall equally apply to the destination member country for the acceptance of postal items from such ETOEs and IMPCs.
5. Member countries shall inform the International Bureau on their policies with regard to postal items transmitted and/or received from ETOEs or IMPCs. Such information shall be made available on the Union’s website.
6. Strictly for the purposes of this article, ETOEs shall be defined as offices or facilities established for commercial purposes and operated by designated operators or under the responsibility of designated operators on the territory of a member country or territory other than their own, with the objective of drawing business in markets outside their respective national territory. IMPCs shall be defined as international mail processing facilities for the processing of international mail exchanged either in order to generate or receive mail dispatches, or to act as transit centres for international mail exchanged between other designated operators.
7. Nothing in this article shall be construed to imply that ETOEs or IMPCs (including the designated operators responsible for their establishment and operation outside their respective national territory) are in the same situation under the Acts of the Union as designated operators of the host country, nor impose a legal obligation on other member countries to recognize such ETOEs or IMPCs as designated operators on the territory where they are established and operated.
