Customs directors from Burkina Faso, Mali, Niger and Togo met in Ouagadougou this week to review a draft preferential tariff regime for the Confederation of Sahel States, the clearest sign yet that West Africa’s breakaway bloc intends to build a customs union of its own rather than rejoin the one it left.
OUAGADOUGOU, OCTOBER 19, 2026
Senior customs officials from the three member states of the Confederation of Sahel States met their Togolese counterpart in Ouagadougou on 15 and 16 October to review a draft decision establishing a preferential tariff regime for goods originating within the confederation, according to reporting on the meetings. The directors general took up conclusions prepared by a technical expert group that had met in the Burkinabe capital from 12 to 14 October.
The draft decision would give goods certified as produced within the confederation preferential treatment at the borders of its member states. Alongside the tariff element, the experts worked on rules of origin, on a certification mechanism for establishing origin, and on shared electronic links between the customs administrations of the participating states.
Burkina Faso’s customs director general, Yves Kafando, opened the expert talks and called for closer cooperation with Togo. The inclusion of Togo, which is not a member of the confederation, is the detail that gives the exercise its commercial logic.
Why Togo is at the table
Burkina Faso, Mali and Niger are landlocked. Every container of imported manufactured goods, every tonne of fertiliser, every piece of mining equipment and every barrel of refined fuel that enters those three countries arrives through a port in a neighbouring state and then travels overland.
Historically much of that traffic moved through Nigerian, Beninese and Ivorian ports as well as through Togo. Political ruptures between the confederation states and several coastal neighbours have narrowed the practical options. Lome, Togo’s capital and port, has become the primary maritime gateway for goods bound for the Sahel economies, and the Lome to Bamako corridor is the spine of the confederation’s import supply.
Togo’s revenue authority, the Office Togolais des Recettes, collects the country’s taxes and customs duties and has been working with the confederation’s customs services on interconnection. The first phase of electronic customs links on the Lome to Bamako corridor went live on 10 March 2025, according to the reporting on this week’s meetings. A follow-up customs meeting was held in Bamako on 2 and 3 October 2025, and its conclusions were reviewed at the Ouagadougou talks.
A delegation from the Lome port alliance is scheduled to visit Ouagadougou and Bamako between 18 and 24 October and again from 2 to 8 November, which indicates that the commercial side of the corridor relationship is being developed in parallel with the customs side.
What the draft decision does not yet resolve is Togo’s own status. It is unclear from the published accounts whether Togolese goods would benefit from the confederation’s preferences, or whether Togo’s participation is limited to transit facilitation. That question has substantial implications for Togolese exporters and for the political trajectory of a country that has maintained working relationships on both sides of the regional divide.
The bloc that left
The Confederation of Sahel States was formed in July 2024 by Burkina Faso, Mali and Niger, three countries then under military governments that had announced their withdrawal from the Economic Community of West African States earlier that year. The stated grievance was the regional bloc’s response to the security crisis in the central Sahel, which the three governments characterised as inadequate, and its imposition of sanctions following the changes of government in each country.
ECOWAS has been in existence since 1975 and operates a customs union with a common external tariff and free circulation of originating goods among its members. Departure from that framework meant that goods moving between the three confederation states and the remaining ECOWAS members lost their duty-free status, at least as a matter of formal law.
In March 2025 the confederation announced a 0.5 percent levy on imports from outside the three member states, with humanitarian aid exempted. The levy was presented as a funding mechanism for the confederation’s economic and military objectives. Its practical effect was to apply a charge to goods from ECOWAS members that had previously circulated without duty.
The economic significance of that rupture is concentrated rather than general. Nigeria, the regional economic centre, exported roughly 290 million US dollars of goods to Niger, 22 million to Burkina Faso and 17.4 million to Mali in 2022, according to figures from the Observatory of Economic Complexity cited in Nigerian business press. Those are modest numbers against Nigeria’s total external trade. They understate the relationship considerably, because a large share of cross-border commerce in the region is informal and does not appear in customs statistics.
Obiora Madu, a Nigerian trade expert quoted in the same coverage, described the levy as a trade barrier with consequences flowing in both directions, noting that the landlocked states depend on shipments passing through Nigeria and other coastal states. He anticipated rerouting through Togo, with slower transactions as a result, and warned of possible border tensions and ECOWAS retaliation. His summary judgement was that everybody is losing.
Building a customs union from scratch
What the Ouagadougou meetings represent is an attempt to replace what was lost. A preferential tariff regime among three states, with rules of origin, certification machinery and interconnected customs systems, is the architecture of a customs union. Building one is difficult, expensive and slow even for states with substantial administrative capacity and stable revenue bases.
The three confederation members have none of those advantages. All three face active insurgencies across significant portions of their territory. All three depend heavily on customs duties for government revenue, which creates an immediate tension with any scheme that reduces collections on intra-bloc trade. All three operate customs administrations that have been under strain for years.
The technical work on rules of origin is where the exercise will succeed or fail. Preferential treatment requires a definition of what qualifies as originating, a procedure for certifying it, and an enforcement capability sufficient to prevent third-country goods from acquiring preferential status through nominal processing. The three economies have limited manufacturing bases, which means the volume of genuinely originating trade is small, and that in turn means the scheme’s value depends heavily on how the origin rules treat processing of imported inputs.
Set the rules loosely and the regime becomes a channel for duty-free entry of third-country goods, with revenue consequences the member states cannot afford. Set them tightly and very little trade qualifies, and the regime delivers political symbolism rather than commercial effect. Finding the point between those failures is the task the expert group has been working on.
The customs interconnection work is the more immediately valuable component. Electronic links between customs administrations along a transit corridor reduce the cost of moving goods regardless of what tariff regime applies, by cutting duplicate declarations, shortening clearance times and reducing opportunities for diversion of transit cargo into the domestic market. Fraud prevention and transit security were identified as key issues at the Ouagadougou talks.
The AfCFTA complication
All three confederation states remain parties to the African Continental Free Trade Area, the continental agreement that aims to eliminate tariffs on 90 percent of goods across a market of 1.3 billion people. That creates an overlapping obligation structure that is awkward at best.
A regional preferential regime is permissible under the continental framework, and the continental agreement explicitly preserves existing regional economic communities. But a bloc that has left one regional community to form another, while retaining continental obligations, faces a sequencing problem. Which schedule applies to a given consignment, and how origin is determined across overlapping regimes, are questions that require legal and administrative answers the confederation has not yet published.
Madu, in the Nigerian coverage, assessed that the continental agreement would definitely be affected by the regional rupture and that West Africa risked becoming its weakest link. The continental project’s credibility rests substantially on the regional communities functioning as building blocks, and a fragmenting West Africa undercuts that premise.
Stakeholder positions
For the confederation governments, the preferential regime is a sovereignty project as much as a trade one. Having left ECOWAS on political grounds, the three states have an interest in demonstrating that the alternative arrangement is functional. Delivery of a working customs regime would be evidence for that proposition. Failure to deliver would be evidence against it.
For Togo, the position is commercially attractive and politically delicate. Lome’s port benefits directly from becoming the preferred gateway for three landlocked economies, and the port alliance delegation visits scheduled for late October and early November indicate that Togolese commercial interests are actively pursuing that opportunity. At the same time Togo remains an ECOWAS member, and deepening customs integration with a bloc that left ECOWAS carries political risk within the regional community.
For ECOWAS and its remaining members, the Ouagadougou meetings are a signal that the confederation is institutionalising rather than reconsidering. Nigerian, Ivorian, Ghanaian and Beninese exporters have an interest in restored access to the Sahel market, and their governments have an interest in avoiding the permanent loss of a regional integration project that has taken five decades to build.
For the trading and logistics sector, the practical effect is already visible in routing. Corridor choice in West Africa has shifted materially over the past two years, and the infrastructure, clearance capacity and commercial relationships that follow that shift are becoming established. Routing patterns, once set, are costly to reverse.
Economic impact
The direct trade effects of a preferential regime among three low-income, largely agricultural and extractive economies will be small in absolute terms. Intra-bloc trade among Burkina Faso, Mali and Niger is limited by similar production structures, poor transport links and the security situation across the border regions where much of it would occur.
The indirect effects are larger. Transit costs determine landed prices for almost everything consumed in the three countries, from fuel to fertiliser to pharmaceuticals. A functioning corridor arrangement with interconnected customs systems and reduced clearance friction lowers those costs across the entire import basket. The customs interconnection component of this week’s work is therefore likely to deliver more measurable welfare benefit than the tariff preferences.
Revenue is the binding constraint. Customs duties account for a large share of government revenue in all three states, and the fiscal position of each is strained by security spending. A preference regime that reduces collections without a compensating revenue mechanism is not sustainable. The 0.5 percent levy on imports from outside the confederation was explicitly a revenue instrument, and the interaction between that levy and the new preferential regime will determine the scheme’s fiscal viability.
There is also a price level effect to consider. Goods from ECOWAS neighbours that previously entered duty free now bear the levy, and goods from elsewhere bear both the levy and the applicable tariff. In economies where food price inflation is a direct driver of political instability, raising the cost of imported staples is a consequential policy choice, and the preferential regime does nothing to offset it for goods that do not originate within the bloc.
Implications for importers, exporters and supply chains
For companies shipping into the central Sahel, the immediate practical implication is that corridor selection has become a strategic rather than an operational decision. The Lome corridor is being actively developed with customs interconnection and political support. Other routes face varying degrees of friction. Companies with existing arrangements through alternative ports should assess whether those arrangements remain the lowest total cost option.
For ECOWAS-based exporters, the 0.5 percent levy remains in force and the new preferential regime will not extend to them. Goods that previously moved duty free under the ECOWAS trade liberalisation scheme now require full duty treatment. Companies that have not re-priced their Sahel business to reflect that change should do so, and should verify that their customs documentation reflects the current legal position rather than the pre-2025 one.
For companies with production footprints in the region, the emerging preferential regime creates a potential incentive to locate processing within the confederation in order to qualify for intra-bloc preferences. Whether that incentive is real depends entirely on the rules of origin, which have not been published. No investment decision should be taken on the basis of preferences whose qualifying criteria are unknown.
For logistics operators, the customs interconnection programme is the development to track. Electronic transit systems reduce costs and accelerate clearance where they work, and they create new compliance requirements where they are introduced. Operators on the Lome to Bamako corridor should expect the second phase of interconnection to impose declaration and tracking obligations that differ from current practice.
For compliance functions generally, the overlapping obligation structure in West Africa is now genuinely complex. A single consignment may touch the continental free trade agreement, the ECOWAS scheme, the confederation’s preferential regime, national tariff schedules and the confederation levy, with different origin rules applicable under each. Documentation errors in that environment are easy to make and expensive to correct.
What to watch
The first marker is adoption. The draft decision reviewed in Ouagadougou requires approval by the confederation’s own organs, and the final text may differ from what the experts produced. Until adoption, there is no regime.
The second is publication of the rules of origin and the tariff schedule. No tariff rates, no product coverage list and no trade volume projections have been released. Without those, the scheme cannot be assessed commercially.
The third is the start date and the treatment of Togo. Whether Togolese goods receive preferences, and when the regime begins to operate at the border, will determine its early commercial significance.
The fourth is the ECOWAS response. The regional community has an interest in preventing permanent fragmentation, and the construction of a parallel customs architecture raises the cost of eventual reintegration. Whether ECOWAS treats this as an opening for negotiation or as a fait accompli will shape West African trade for a decade.
For now, the significance of the Ouagadougou meetings is directional rather than quantitative. Three governments that walked out of a fifty-year-old customs union are building the machinery of their own, and a coastal neighbour outside their bloc is helping them do it.
The corridor economics
To understand why customs interconnection matters more than tariff preferences in this case, it helps to look at the cost structure of landlocked trade. Studies of West African corridors have consistently found that the overland leg, from port gate to inland destination, accounts for a large multiple of the maritime freight cost on the same consignment, and that a substantial share of that overland cost is not transport at all but delay, documentation and informal payments at checkpoints and border posts.
A tariff preference of a few percentage points on the small volume of genuinely intra-bloc trade is worth little against that. A transit system that reduces clearance time at the port and eliminates re-declaration at each border is worth a great deal, and it applies to the entire import basket rather than to a qualifying subset.
This is why the detail about the first phase of electronic customs links going live on the Lome to Bamako corridor in March 2025 is more commercially significant than the draft tariff decision the directors general reviewed this week. It is also why the fraud and transit security discussions matter. Transit regimes fail when goods declared for onward movement are diverted into the domestic market of the transit state, and the revenue authorities of both the transit country and the destination country lose. Electronic tracking and shared data are the standard answer, and implementing them across three strained administrations is a genuine achievement if it holds.
Precedents and prospects
Regional customs arrangements built by small groups of states outside a larger bloc are not unprecedented, and the record is mixed. Where such arrangements have succeeded, they have usually had three features: a member state with the administrative capacity to carry the technical load, a source of external financing for the systems investment, and a reasonably large volume of genuinely intra-regional trade to make the preferences meaningful.
The confederation has the third in limited supply and the second in doubt, given the state of its members’ relationships with traditional development partners. The first is an open question. The involvement of Togo, which operates a functioning revenue authority and a commercially significant port, may be the mechanism through which that capacity gap is partially filled, which would be an unusual arrangement and a pragmatic one.
The alternative trajectory is that the preferential regime is adopted, published, and then implemented patchily or not at all. That outcome is common in regional integration schemes across the continent and elsewhere, where instruments are agreed at the political level and never operationalised at the border. The distinguishing feature of this exercise so far is that the customs technicians have been engaged in parallel with the political process rather than after it, which improves the odds.
The wider pattern
Viewed from outside the region, the Sahel exercise is a small instance of something visible across the trading system. Where multilateral and established regional frameworks have lost political legitimacy with a group of members, those members build alternatives. The alternatives are smaller, less efficient and more fragile than what they replace, and they are built anyway, because the political cost of remaining inside the original framework has come to exceed the economic cost of leaving it.
The same logic is visible in the proliferation of bilateral preferential agreements elsewhere, in the plurilateral workarounds that have grown up around the impaired World Trade Organization dispute settlement system, and in the managed-trade arrangements that major economies are now negotiating in place of rules-based outcomes.
The aggregate effect is a trading system in which the rules applicable to a given transaction depend increasingly on which of several overlapping instruments the parties invoke, and in which the administrative capability required to trade is rising. For large firms with dedicated customs functions, that is a cost. For small traders in low-income economies, it is frequently a barrier, and the informal sector that already dominates cross-border commerce in West Africa grows accordingly.
That is the part of this story that reaches beyond the Sahel. A preferential tariff regime among three of the world’s poorest countries will not move global trade statistics. What it illustrates about how trading arrangements are now being built, and taken apart, applies considerably more widely.
