Artikel 10

1. In order to avoid, in principle, examination of the registered baggage of passengers in transit through the territory of a country, and of parcels carried in transit by international passenger trains, the Customs and other administrations concerned of the Contracting Parties shall, in agreement with the railway administrations of the said Parties, take special measures, such as sealing baggage compartments or vans, or the containers, skips or sacks in which such baggage is carried, or affixing seals to the parcels themselves, provided an international Customs declaration form is completed.
2. In agreement with the railway administrations of the countries concerned, the Customs and other administrations concerned of the said countries shall establish, 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 Customs clearance and other examinations of registered baggage and of parcels carried by passenger trains, 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 baggage and parcels may be carried under the international transit system referred to in paragraph 1 of this article.
3. Railway administrations shall wherever possible endeavour to arrange for registered baggage and parcels carried by international passenger trains to be cleared through the Customs and to undergo the other examinations before they are loaded at the station of dispatch.
4. If at frontier stations packages cannot be cleared through the Customs and examined in the time specified under article 6, paragraph 4, they shall be unloaded and the train shall not be held up.
5. 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, unless any simpler system is in force;
(c) the standard international Customs declaration form shall be printed in two languages, French and the language of the country of dipatch; 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.
6. This standard international Customs declaration form may be modified in accordance with the simplified procedure described in article 16 of this Convention.
