Customs and excise duties used to provide a large portion of all tax revenues, but following accession to the World Trade Organization, they are no longer so high. All imports and exports are subject to licenses. Import duties are levied by CIF (cost, insurance, and freight) value, with a 0% to 30% rate. There is also a 13% value-added tax (VAT) that is applied to both imported and domestically produced goods. Jordan grants preferential treatment to imports from Arab League countries, under bilateral trade agreements that exempt certain items from duty and under multilateral trade and transit agreements with Arab League countries. Jordan also signed a bilateral free trade agreement (FTA) with the United States in October 2000.
