Import dumping can occur when a company exports a product to another country at a price that is lower than the cost of production, or when a company sells a product in a foreign market at a price that is lower than the price it charges in its domestic market. Import dumping can be harmful to domestic producers in the importing country, as it can drive down prices and make it difficult for them to compete. Some countries have laws that prohibit import dumping, as it can be seen as unfair competition.
