Dumping is a term used in international trade when the context of international trade when a country or company exports a product at a price that is lower in the foreign importing market than the price in the exporter's domestic market. Dumping typically involves substantial export volumes of a product so it often endangers the financial viability of the product's manufacturers or producers in the importing nation. Dumping is legal under WTO rules unless the foreign country can reliably show the negative effects the exporting firm has caused its domestic producers.
