In an economic context where industrial sovereignty is becoming a priority for member states, CEMAC is taking a new step in its regional integration. The sub-regional organization is now focusing on a coordinated management of its borders to transform its productive landscape. At the heart of this dynamic is the harmonization of customs practices, a lever considered essential to facilitate trade while protecting the interests of local producers. Concretely, this reform is structured around the optimization of goods valuation mechanisms as well as a rigorous and unified application of the common external tariff. The stated objective is twofold: to strengthen economic cohesion within the CEMAC area and to establish a solid foundation for the import-substitution policy. By favoring locally manufactured products over massive imports, the zone's authorities hope to durably stimulate national and regional investment. This structural approach responds to a pressing need for the diversification of Central African economies, which are often too dependent on fluctuations in raw material prices and external flows. While these measures mark a real advance in the structuring of the common market, the success of this import-substitution policy will henceforth depend on the ability of national actors to increase their competitiveness and production capacity to meet regional demand. Details on the timetable for the full implementation of these new customs provisions, however, remain a point of attention for economic operators in the region.
