Dar es Salaam is Tanzania's main distribution center. Mombasa, in Kenya, and inland Tanzanian towns also serve as trade centers. Previously, Tanzania used non-tariff trade barriers to protect local industries and domestic commerce. With trade liberalization, tariff barriers have been adjusted for this purpose. Most retail shops are small, privately owned establishments that specialize in one or two specific products.
