One method of limiting imports is simply to close the ports of entry into a country. More commonly, maximum allowable import quantities may be set for specific products. Such quantity restrictions are known as quotas.
These may also be used to limit the amount of foreign or domestic currency that is permitted to cross national borders. Quotas are imposed as the quickest means to stop or even reverse a negative trend in a country's balance of payments.
They are also used as the most effective means of protecting domestic industry from foreign competition.
