What is the 'WTO take' on Anti-Dumping Duty? What are the two parameters to assess dumping?

An 'anti-dumping duty' is a protectionist tariff that a domestic government imposes on foreign imports that it believes are priced below fair market value. For protection, many countries impose stiff duties on products they believe are being dumped in their national market, undercutting local businesses and markets. The WTO operates a set of international trade rules. Part of the organization's mandate is the international regulation of anti-dumping measures. The WTO does not regulate the actions of companies engaged in dumping. Instead, it focuses on how governments can-or cannot-react to dumping. In general, the WTO agreement allows governments to "act against dumping where there is genuine (material) injury to the competing domestic industry." In other cases, the WTO intervenes to prevent anti-dumping measures. There are two fundamental parameters used for determination of dumping, namely, the normal value and the export price. Both these elements have to be compared at the same level of trade, generally at ex-factory level, for assessment of dumping. Normal value is the comparable price at which the goods under complaint are sold, in the ordinary course of trade, in the domestic market of the exporting country. The Export price of the goods allegedly dumped into India means the price at which it is exported to India. It is generally the CIF value minus the adjustments on account of ocean freight, insurance, commission, etc. so as to arrive at the value at ex-factory level.
