An imported car can sit at a Nigerian port for weeks or months while demurrage and storage charges mount. The causes are rarely mysterious. Most long delays trace back to documentation failures, valuation disagreements, system bottlenecks, physical congestion, or compliance problems that prevent Customs and the terminal from releasing the vehicle.
Documentation is the single most frequent culprit. Form M must be opened through an authorised bank before the car is shipped. If it is missing, expired, or does not match the commercial invoice and Bill of Lading, clearance cannot proceed. The Pre-Arrival Assessment Report, or PAAR, must also be processed. Errors in the declared value, HS classification, chassis number or vehicle description lead to rejection or lengthy queries. When the paperwork is inconsistent, the car simply waits until the importer corrects every discrepancy.Valuation disputes produce similar outcomes. Nigeria Customs often determines the CIF value using its own references and VIN-based assessment rather than accepting the invoice price at face value. If the importer contests the assessed value or the resulting duty, the matter can move into prolonged correspondence or formal objection. Until the dispute is resolved and the correct amount is paid, the vehicle remains under Customs control.
Electronic system problems add further delay. The platforms used for declarations, PAAR generation and duty payment occasionally experience downtime or slow processing. When new single-window or trade portals are introduced, temporary integration issues with other agencies can extend the time needed to obtain necessary approvals. A car that would otherwise clear in days can sit for weeks while systems catch up or while officers work around technical glitches.Physical examination and multi-agency checks also consume time. Even after documents are accepted, the vehicle must be inspected. When examinations are sequential rather than joint, or when non-intrusive scanning capacity is limited, queues form. High volumes of cargo at Apapa and Tin Can Island mean that a car may wait its turn for examination long after the paperwork is ready.
Terminal and shipping-line charges create a secondary trap. Once free days expire, demurrage and storage fees begin to accumulate daily. Importers who lack immediate funds to pay both the Customs assessment and the terminal charges find themselves in a cycle: the longer the car stays, the higher the bill becomes, and the harder it is to raise the money for release. In extreme cases the accumulating costs exceed the value of the vehicle.Port congestion and difficult truck access compound the problem. Even after Customs releases a car, moving it out of the terminal depends on available trucks, holding-bay systems and relatively free roads. Gridlock around the ports, illegal checkpoints and poor coordination can keep a released vehicle physically stranded for additional days or weeks.
Compliance failures are another common reason for long detention. Vehicles that exceed the permitted age limit, lack required conformity documentation, or raise red flags during inspection can be held pending further investigation or formal seizure proceedings. Attempts to clear cars with incomplete or irregular history documents frequently end in extended delays.Finally, human and procedural friction plays a role. Multiple interventions by different officers, requests for additional clarifications, and the need to move between agencies slow the process. Importers who rely on informal channels sometimes discover that those channels create more complications than they solve, leaving the car in limbo while issues are sorted out properly.
Most cars that remain at the port for months share a pattern: something in the documentation or valuation was wrong or incomplete, the correction took time, charges escalated, and congestion or system delays stretched the timeline further. The practical lesson for anyone importing a vehicle is to open Form M early, ensure every document matches exactly, budget for the full assessed duty plus terminal costs, and respond quickly to any query. Cars rarely stay at the port for months by accident; they stay because one or more of these predictable obstacles was not cleared in time.
