Chad has run the same customs software since 2002. The upgraded SYDONIA World finally launched in May 2026 — at N'Djamena airport, letting traders exchange clearance documents with customs online.

The strongest source is the operator's or the city's own reporting — an official report, dataset or press release. It grades who did the looking — not how well the project went.

Chad's customs service began switching from the ageing SYDONIA++ system, in place since 2002, to UNCTAD's SYDONIA World platform in October 2021, with a World Bank-funded rollout piloted at N'Djamena's Hassan Djamouss airport that lets traders file declarations and scanned documents online from their own offices. The platform exchanges data in real time with the tax administration and the treasury. The customs directorate credits the reform for 2025 revenues reaching 127 percent of the finance-law target — its own figure, not an independently audited one. Independent reporting from February 2026 shows the limits: hauliers still wait up to five days for clearance, and paper-based and digital procedures continue to run side by side.
📊 Impact
Customs revenues reached 127.19% of Chad's 2025 finance-law target, a figure the customs directorate itself attributes to the digitalisation reforms; no independent audit of that attribution exists.
🎓 Lesson
Digitising declarations does not by itself remove the manual steps that run alongside them: four years in, revenue collection is up while clearance still takes up to five days because paper and digital procedures coexist.
