If companies import or export goods from outside the Switzerland-Liechtenstein customs union, these are deemed to be trade goods and must be declared to the FCA in writing for import or export. For this purpose, the company must identify itself by means of its UID as of January 1, 2016
It makes no difference whether the goods are for 

• the manufacture, that is, for processing or production such as raw sheet metal for molding, wood for furniture construction or electronic controls for installation,
• the "own needs" such as the company vehicles, office supplies or tools of their own operation,
• or the "Retail resale" such as the office supplies of the Papetrie, the books of the bookstore or the cars of the vehicle salesman acts.

As with the exporters, the possibility of representation is not given.

If you recognize your company in one or more of these groups, you are strongly advised to apply for a UID
