The concept of anti-dumping find its roots in the trade practices of 1930s when many countries resorted to dumping of goods into foreign countries at extremely low prices for earning foreign exchange. Manipulative currency practices such as devaluation of currency, was very popular in such countries for cost reduction of goods manufactured and traded globally by domestic industries.Anti-dumping legislation arose at the end of the nineteenth century as a policy alternative to frequent revision of import tariffs and was used by different countries to protect their domestic industries from the ill effects of dumping. Canada was the first country to launch antidumping measures in 1904 against American firms who were found dumping steel at discriminatory prices. Many Commonwealth countries also followed suit and imposed anti-dumping duties during next ten years on the predatory pricing policies of exporting countries. The perceived threat of predatory practices resulted in the first American anti-dumping legislation under the Revenue Act of 1916. In 1921 Australia, Great Britan, New Zealand and the United States implemented new antidumping statutes. Along with Canada's original legislation, these legislations served as the foundation for Article VI of The General Agreement on Tariff and Trade (GATT), 1947. The unsuccessful struggle of League of Nations between the two World Wars on the issue of dumping and differential pricing gave a thrust to the post war efforts of formation of International Trade Organisation and GATT. The General Agreement on Tariff and Trade (GATT) 1947 was the first effort to lay down the rules governing International Trade for establishing free trade between countries. When the pros and cons of dumping were examined during formation of GATT, it was found that the dumping itself is not a bad practice but can be a kind of booster to the industry. Dumping was found to be a source of additional revenue to the industry and also benefitted the consumers by availability of goods at cheaper rate. The dumping, therefore, was not prohibited under the GATT but, when dumping was seen causing any kind of injury to the domestic industry of importing country, then, to nullify the effect of dumping, the GATT allowed its signatory Countries to take anti-dumping measures. The United States of America was the first member nation to address the unfair trade practices of dumping and subsidized exports before the watchdogs of international trade. There was general support for antidumping and countervailing measures, though there were differences on the scope of dumping definition and on retaliatory measures other than anti-dumping duties. The developing countries favoured a wider definition to include price, service, exchange and social dumping, whereas the developed countries favoured a narrower definition to avoid opening up of a wide range of retaliatory measures. On the question of retaliatory measures the imposition of quantitative restrictions was finally avoided and antidumping duties were accepted as the right course to neutralize dumping margins. Thus the first multinational rules and conditions on antidumping under which individual countries were justified in taking defensive measures, were incorporated in Article VI of GATT.
