The three regional economic communities (RECs) in Eastern and Southern Africa are the Common Market for Eastern and Southern Africa (COMESA), the East African Community (EAC) and the Southern African Development Community (SADC). Together, they have recognised the need to work towards regional cooperation aimed at the eventual creation of a single regional economic community or Tripartite Free Trade Agreement (TFTA). This will replace the existent RECs in Eastern and Southern Africa to which the member states of these two regions have multiple membership.

These statistics translate into a potential regional economic powerhouse for Eastern and Southern Africa. One of the major goals of the TFTA is to harmonise trade arrangements among the three RECs, improve the movement of goods and persons within the single integrated region, facilitate the joint implementation of regional infrastructure projects and enhance co-operation of member states. This is a laudable initiative by the member states of the three RECs and it is recognised that regional integration is the first step towards integration into a multilateral trading system. For the TFTA member states, it is crucial that there is an awareness to move towards a review of domestic customs legislation and policy and to develop regional, supranational legislation and regulations in order to gain a stronger competitive edge in the global market. This study shies away from proposing a quick fix or instant benefit to the harmonisation of TFTA member states customs legislative frameworks and policies and the development of a single automated, interoperable electronic customs system. Rather, it places its focus on long-term sustainable benefits which will be realised over time. The harmonisation of TFTA member state customs legislative policies and t
