Artikel 22

1. As a general rule and except when they examine the goods in accordance with article 5, paragraph 2, the Customs authorities of the Customs offices en route of each of the Contracting Parties shall accept the Customs seals of other Contracting Parties, provided that they are intact. The said Customs authorities may, however, if control requirements make it necessary, add their own seals.
2. The Customs seals thus accepted by a Contracting Party shall have in the territory of that Contracting Party the benefit of the same legal protection as is accorded to the national seals.
