Tariff schedules give preferential treatment to imports from the United Kingdom and other Commonwealth countries. Zambia belongs to the Common Market of Eastern and Southern Africa (COMESA) and the Southern African Development Community (SADC), both committed to free trade by 2004. Rebates are allowed on certain capital goods and on most materials used in local manufacturing industries. Tariff protection also is accorded to selected new industries. Most imports require licenses. Import duties ranged from 5% for raw materials and capital equipment, 15% for intermediate goods, and 25% on final products in 2002. Selected items, such as soaps and vegetable cooking oils, carry special protective tariffs. There are no free trade zones.
