What is anti-dumping duty?

If any company exports a product at a price lower than what it normally charges in its home market, then it is dumping the product. Opinions differ as to whether or not this is unfair competition, but many countries take action against dumping by imposing anti-dumping duty. Thus, anti-dumping duty is an extra import duty on a particular product from a particular country in order to bring its prices closer to the normal value of that product in the country it is imported to. It is done to protect its own industry from predatory pricing. The World Trade Organisation does not prohibit anti-dumping policies and allows any country to take anti-dumping action against the countries which violate the principles of General Agreement on Trade and Tariff.
