Answer:
The sale of a good abroad at a cheaper price than what the good is sold for in the producer's domestic market.
Explanation:
Dumping is sale of good in foreign markets, at lower price than the domestic market price. It has an injuring effect on their domestic producers & sellers, as they lose their market share to foreign cheaper sellers. This creates monopoly of foreign sellers in imported markets, driving out domestic competitors. Implicatively, it also implies that foreign sellers dictate price & quality of products in imported markets.
Dumping is highly detrimental to imported countries producers & sellers. So, World Trade Organisation has strict rules against it.
