Since about 1950, tariffs have been used primarily to protect Iraqi industry or to stimulate industries that might eventually reduce the need for foreign imports. This tariff system levies duties on luxury items but has reduced rates on industrial equipment and on certain raw materials and foodstuffs. Iraq has a single-column tariff, with duties collected at Basra and Baghdad. In October 1992, Iraq banned the import of 157 "luxury items," including cheese, onions, shampoo, matches, shoes, and carpets. In 1989, Iraq joined the newly formed Arab Cooperation Council with Egypt, Jordan, and Yemen. The ACC's goals included formation of a common market and economic integration in other areas. The international embargo levied against the nation after it invaded Kuwait has essentially ended Iraq's participation in the ACC. Egypt, one of its partners in the Council, was a leader in the military coalition that liberated Kuwait.
