As set out in Article 23 of the Weapons Act, weapons, key components of weapons, arms accessories, ammunition and ammunition components must be declared at the time of importation or transit in passenger traffic, in accordance with Article 25 of the Customs Act of 18 March 2005.
Pursuant to Article 43 of the Weapons Ordinance, foreign members of diplomatic and consular missions, permanent missions and special missions are exempt from the obligation to show any weapons at the customs office and to declare them in accordance with Articles 21 and 25 of the Customs Act when the weapons in question can be considered as articles for personal use within the meaning of the Convention of 26 June 1990 on temporary admission (i.e. only two hunting weapons or two sporting weapons, or a hunting weapon and a sporting weapon, with the accompanying ammunition, or a weapon for alarm or warning purposes, provided that it does not have the capacity to fire pyrotechnic ammunition).
The importation of weapons is subject to authorisation (Art. 25 WA). Pursuant to Art. 25a, para. 3 (b) of the Weapons Act and Art. 42 (a) of the Weapons Ordinance, foreign members of diplomatic and consular missions and permanent missions accredited to Switzerland are exempt from the requirement to obtain an import permit for the provisional introduction of weapons into Swiss territory.
This provision does not apply to missions as such, which remain subject to the duty of authorisation and declaration (Articles 42 and 43 of the Weapons Ordinance, in conjunction with Articles 21 and 25 of the Customs Act).
The importation of weapons must also be carried out in accordance with the Ordinance on the Customs Privileges of Diplomatic Missions in Bern and Consular Posts in Switzerland (SR 631.144.0) or the Ordinance of 13 November 1985 on the Customs Privileges of the International Organisations, of States in their Relations with such Organisations and of the Special Missions of Foreign States (SR 631.145.0).
Weapons must be declared in the following cases:
when they are part of personal effects at the time of moving to Switzerland;
in the case of a consignment entering Switzerland by rail, road or air, or exiting a free port.
A declaration is not required for passenger traffic, in so far as weapons may be considered as articles for personal use under the Convention of 26 June 1990 on Temporary Admission.
