In economics, "dumping" can refer to any kind of Predatory Pricing. However, the word is now generally used only in the context of international trade law, where dumping is defined as the act of a manufacturer in one country exporting a product to another country at a Price which is either below the price it charges in its home market or is below its Costs of production (http://en.wikipedia.org/wiki/Dumping_%28pricing_policy%29)
