An exporter is a person, company, or country that sends goods or services to a counterparty in another country. Exporting is a global trade function whereby goods produced in one country get moved to another country to trade or sell.
Importers bring a foreign country's goods into their home country to resell in the domestic market, while exporters send goods from their home country to a foreign country to sell.
Importers of goods fulfill the demand for a particular product that 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.
