Verbal customs declaration
When the border crossing is manned by Customs staff, you must spontaneously declare all goods (including animals and repairs carried out abroad) that you are carrying with you. The verbal declaration is binding.

Written customs declaration
In less frequented locations, there are more and more border crossings that are manned only from time to time, or not at all. At border crossings such as these, so-called declaration boxes are partially available for you to declare your goods in writing. For the procedure, see declaration box
This form of customs declaration is permitted only for goods which are not intended to be sold or traded, which are not subject to any restrictions or bans, and require neither a certificate nor an authorisation. Merchandise must be declared at a competent customs office.
N.B. Customs inspections may also be carried out in Switzerland itself. In the case of such an inspection, it will no longer be possible to carry out a customs declaration which should have been done beforehand. Consequently, you are committing a criminal offence if you do not declare or falsely declare prohibited or dutiable goods or ones that require authorisation.
