Import finance allows both the importer and exporter to be free from assuming an excessive amount of risk.
An import is a good brought into a jurisdiction, especially across a national border, from an external source. The party bringing in the good is called an importer.[1][2] An import in the receiving country is an export from the sending country. Importation and exportation are the defining financial transactions of international trade. In international trade, the importation and exportation of goods are limited by import quotas and mandates from the customs authority. The importing and exporting jurisdictions may impose a tariff (tax) on the goods. In addition, the importation and exportation of goods are subject to trade agreements between the importing and exporting jurisdictions.
