Transfer of domicile to Switzerland is the most important requirement in order to have your household goods and any collections, animals or your car imported into Switzerland duty-free. Further the imported articles must have been used by you personally for at least 6 months and they have to be continued to be used by you after importation. Students
Household goods, personal effects and students' educational materials can be imported duty-free. This applies even if the domicile is not transferred to Switzerland. Procedure in the case of importation
