Prior to 2014 the organisers made arrangements for the cars to be imported into Mongolia without import duties. From 2004-06 they made use of a standard procedure used by non-profit making organisations, charities, and non-governmental organisations in Mongolia that provides exemption from the most significant taxes levied on older vehicles. Under Mongolian law the importing organization in Mongolia was then prevented from selling the vehicle for 3 years. Since 2007 the organizers had a special agreement with the Mongolian government. The cars will be auctioned and the money raised donated to a project as chosen by the drivers of each car.
