Customs on your household

Your household can be imported duty and tax free into Switzerland.  Your furniture, personal effects, electrical appliances, etc., have to be in your possesion and for personal use for at least 6 months prior to your move.   The importation of your goods should occur within a reasonable period of time after your change of residence to Switzerland.  For pets, motor vehicles, etc., or for more detailed information, you may consult the rules and regulations of the official customs authorities.
