A situation in which goods are sold to a foreign market at a disproportionately low price (i.e. below the domestic market price or below the cost of production) in order to gain a competitive advantage over other suppliers. Dumping is considered an unfair practice under GATT and WTO (World Trade Organisation) rules. It is regulated by individual countries through the imposition of anti-dumping duties, in some cases calculated to make up the difference between the price of the product in the importing country and the exporting country.
