Dumping is defined as selling a product in another country for less than production cost. Shrimp producers from Country F are selling shrimp in Country G below the cost of producing shrimp in Country G. So Country F' s producers are dumping shrimp.
In order to evaluate the argument above, it is necessary to determine whether production cost in the definition of dumping refers to the cost of producing the product in the country where it originates or in the country where it is sold.
