Who are importers and exporters?
Importers bring a foreign country's goods into their home country to resell in the domestic market. While exporters send goods from the home country to a foreign country to sell.
Importers of goods fulfil the demand for a particular product which is not present or in short supply in the importer's domestic country. An increase of importing reveals growing domestic demand, indicating an expanding economy.
The primary reason to export goods overseas is to satisfy the demand identified. A trade surplus, which occurs if a country exports more than it imports, is considered beneficial for its overall growth.
