Artikel 7

1. The Customs and other administrations concerned shall, in agreement with the railway administrations of their respective countries, take such special measures as appear advisable for the purpose of speeding up, in particular, the examination of goods in international transit.
2. In agreement with the railway administrations of the countries concerned, the Customs and other administrations concerned of the said countries shall estabish, so far as possible, offices at those stations in the interior of the said countries where international traffic is particularly heavy, in order to permit the examination and Customs clearance of goods, either before departure from such stations or on arrival there. Between one such station in the interior of a country and a frontier station in either direction or between two such stations in the interior of two countries, such goods may be carried under the international transit system referred to in paragraph 1 of this article.
3. With a view to the application of the provisions of the present chapter:
(a) the Contracting Parties shall recognize, in principle, the Customs seals of the other Contracting Parties, subject to the right of each Customs administration to add its own seal, should it deem this essential;
(b) the Contracting Parties shall adopt the standard international Customs declaration form annexed to this Convention;
(c) the standard international Customs declaration form shall be printed in two languages, French and the language of the country of dispatch; unless otherwise provided, it shall be made out in duplicate for each country;
(d) the declaration by the consignor shall be made in Latin characters and in the language of the country of dispatch or in French, and where necessary the railway administration will be responsible for its translation; and
(e) this regulation does not rule out the possibility for Customs and railway administrations which see fit to do so, to allow the use of other languages in connexion with traffic exclusively concerned with their particular country.
4. This standard international Customs declaration form may be modified in accordance with the simplified procedure described in article 16 of this Convention.
