what is Dumping?
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. 

What is Anti-Dumping
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.

Legal definition of dumping
It means export of goods by a country to another country at a price lower than its normal value. Thus, dumping implies low priced imports only in the relative sense (relative to the normal value), and not in absolute sense.Import of cheap products through illegal trade channels like smuggling; do not fall within the purview of anti-dumping measures.

Difference between Anti-Dumping and Normal Custom Duty Charge
Although anti dumping duty is levied and collected by the Customs Authorities, it is entirely different from the Customs duties not only in concept and substance, but also in purpose and operation. The following are the main differences between the two: - 
a. Conceptually, anti dumping and the like measures in their essence are linked to the notion of fair trade. The object of these duties is to guard against the situation arising out of unfair trade practices while customs duties are there as a means of raising revenue, and for overall development of the economy.
b. Customs duties fall in the realm of trade and fiscal policies of the Government while anti dumping and anti subsidy measures are there as trade remedial measures.
c. The object of anti dumping and allied duties is to offset the injurious effect of international price discrimination while customs duties have implications for the government revenue and for overall development of the economy.
d. Anti dumping duties are not necessarily in the nature of a tax measure in as much as the Authority is empowered to suspend these duties in case of an exporter offering a price undertaking. Thus, such measures are not always in the form of duties/tax.
e. Anti dumping and anti subsidy duties are levied against exporter / country in as much as they are country specific and exporter specific as against the customs duties which are general and universally applicable to all imports irrespective of the country of origin and the exporter.

Thus, there are basic conceptual and operational differences between the customs duty and the anti dumping duty. The anti dumping duty is levied over and above the normal customs duty chargeable on the import of goods in question.
