mr. shivam please noted that:

Dumping is said to occur when the goods are exported by a country to another country at a price lower than its normal value. This is an unfair trade practice which can have a distortive effect on international trade.

Anti dumping is a measure to rectify the situation arising out of the dumping of goods and its trade distortive effect. Thus, the purpose of anti dumping duty is to rectify the trade distortive effect of dumping and re-establish fair trade. The use of anti dumping measure as an instrument of fair competition is permitted by the WTO. In fact, anti dumping is an instrument for ensuring fair trade and is not a measure of protection per se for the domestic industry. It provides relief to the domestic industry against the injury caused by dumping.
