In a remote African border, a truck halts as its cargo declaration is re-entered manually. The customs system on one side holds full details about the shipment, including the recipient and paid duties, yet the system just meters away remains unaware. Information tied to a consignment typically does not transfer seamlessly across borders. The central database often stays in a folder on the driver’s dashboard.
In February 2025, the African Union finalized eight annexes to the AfCFTA Protocol on Digital Trade, addressing cross-border data flows, digital identities, digital payments, and emerging technologies. Customs collaboration already has a legal basis under the AfCFTA’s Protocol on Trade in Goods, whose annexes on customs cooperation and mutual administrative assistance, along with trade facilitation, obligate State Parties to collaborate at border points. Most provisions await ratification and domestic implementation. While the rules are nearly complete, the technical infrastructure lags behind.
The divide between guidelines and connectivity
Blaming technology alone overlooks the deeper issue: interoperability often falters due to missing legal frameworks rather than technical limitations. These include agreements for mutual data recognition, acceptance of Authorized Economic Operator status, and adequate data protection standards. Rules of origin exemplify the chasm between policy and practice. In February 2026 the AU Assembly adopted the last outstanding rules, for automotive products, clothing and textiles, completing the AfCFTA’s origin rules on paper. A rule helps a trader only once it sits in national tariff schedules, customs systems and certificate checks, and across much of the continent that work is still under way. Technology follows the legal mandate; once it exists, tech determines if the rulebook delivers cleared containers or just communiqués.
Each country has its own procedures, data standards and systems, built at different times to different specifications. A company I represent has built multiple systems, offering firsthand insight: a platform optimized for one administration’s revenue and compliance goals rarely functions for another. Traders moving through multiple borders face duplicate filings and delays.

The upside is substantial: UNCTAD projects resolving non-tariff barriers could boost African economies by roughly $20 billion annually, over five times the $3.6 billion anticipated from tariff elimination.
National single windows have delivered domestic improvements in many countries. However, lacking an outbound layer to transmit declaration data to subsequent customs authorities, processes collapse at borders, reverting to manual procedures.
Legal and Technical Solutions to Enhance Trade Efficiency
A model bilateral data-exchange agreement and framework for mutual recognition of AEO status would remove the largest source of delay in these projects, which is legal rather than technical. This step focuses on legal rather than technical challenges. Funding and measuring two live trade corridors, paired with a Time Release Study, would establish baseline metrics and connect them to continental profiles. A target such as data reused across the border in 60 percent of consignments, and release time down by a third, is what attracts financing from the AfCFTA Adjustment Fund and the development banks. Integrating PAPSS ensures settlement aligns with paperwork speed.
Why single windows halt at borders
A lesser-discussed constraint compounds the issue. A Single Window is not solely a customs mechanism. Delays frequently stem from non-custom agencies: certification authorities, food and drug regulators, phytosanitary inspectors, and port health units. This is critical. The World Customs Organisation (WCO)’s Time Release Study identifies delay points; all interoperability initiatives must begin and end with such audits.
It would be inaccurate to claim Africa hasn’t addressed cross-border data exchange. It has, through bilateral efforts and repeated collaborations. By May 2025, the ECOWAS SIGMAT transit system operated across nine member states, when the Benin-Nigeria linkage launched at Sèmè-Kraké. On September 11, 2026, the same two nations advanced further. Their Customs Declaration Exchange System pilot connected Benin’s Customs Webb with Nigeria’s B’Odogwu, enabling destination-side officers to view declarations submitted at origin, along with manifests, transit details, and risk alerts.

Each nation retains its duty calculations, risk assessments, and release decisions. This represents federation in action along the Abidjan-Lagos corridor, which Nigerian Customs reports handles roughly 70 percent of West Africa’s transit trade. The East African Community’s Single Customs Territory shares declaration data and cargo tracking on Northern and Central Routes. COMESA’s transit guarantee enables goods to move under a single bond across multiple states. These are functioning systems, created by African institutions.
Scale poses the challenge. Sèmè-Kraké required years of effort to connect a single administrative pair. With 54 signatory nations, there are 1,431 potential bilateral links, each individually negotiated, mapped, maintained, and revalidated during system upgrades. Continental success demands one shared data standard, implemented once per country; one integration per nation, not one per pair.
A common language and technology’s role
The WCO Data Model offers the lexicon, coding lists, and message formats most African administrations aspire to. The obstacle lies in divergent national implementations. Local requirements prompt field additions, undocumented legacy structures persist, and expertise often vanishes. Aligning national systems with the Data Model demands arduous, upgrade-sensitive mapping.
Federation and data ownership
The cautionary tale is TradeLens. Supported by Maersk and IBM, blockchain-based and marketed as an open, neutral industry platform, it ceased operations in 2023. The technology functioned, but participation never reached critical mass. Interoperability yields little value to early adopters: Country A gains nothing until B, C, and D connect. Four priorities thus demand designation, timelines, and metrics:
- Assign the standard. The AfCFTA Secretariat, WCO, and RECs should issue a single continental profile of the WCO Data Model as the mandatory exchange format, coupled with a conformance test. Until one profile is designated, every nation and vendor targets different specifications.
- Create the legal gateway. A model bilateral data-exchange agreement and framework for mutual AEO recognition would eliminate the primary delay in these projects—legal rather than technical.
- Fund and monitor two corridors. Establish baseline studies for two operational corridors using Time Release Studies, integrate them with the continental profile, and publish findings. Targets such as achieving data reuse across borders in 60 percent of shipments and reducing clearance time by one-third will attract financing from the AfCFTA Adjustment Fund and development banks. Align this with PAPSS, ensuring settlement aligns with paperwork efficiency.
- Include traders, including micro-enterprise participants. Broadband, power, and existing border hardware are prerequisites, requiring multi-year infrastructure budgeting. Much intra-African trade is informal, often conducted by women micro-traders. Without simplified procedures and low-value thresholds, interoperability benefits only large carriers, leaving no formalization for smaller actors.
