    Perfect climate in duty-free warehouse

    Switzerland has around a dozen duty-free warehouses. These warehouses are transit zones for the storage of goods, whose main advantages are the temporary suspension of customs law and taxes. They benefit not only from a location in the heart of Europe, but also from legal and political stability. The company Ports Francs et Entrepôts de Genève SA, in which the Canton of Geneva holds an 87% interest, is domiciled in La Praille, where it manages a floor space of 150 000 m² , half of which under the Swiss customs regime (duty-free). The company also maintains storage space (10 000 m²) in the cargo hangar at the international  import in Geneva.
