KEY TAKEAWAY
The combination of seasonal port congestion and a specific transit-levy dispute has created a systemic dwell-time shock that requires proactive communication and buffer-based logistics planning.
Introduction
Mombasa port is currently navigating an acute congestion crisis as it manages peak December import volumes alongside cargo spillover from Dar es Salaam. The situation has been further complicated by a diplomatic and commercial dispute regarding a USD 5,000 security levy on South Sudan-bound containers, which has stalled cargo movement and distorted yard operations. This convergence of operational and policy-driven bottlenecks poses a direct threat to time-sensitive festive-season retail and export commitments.

Operational Mitigation Measures
The Kenya Ports Authority and KRA have implemented immediate tactical responses to alleviate terminal pressure.
Why it matters
✓Relocation of long-stay containerised cargo to Container Freight Stations (CFSs) to clear yard space.
✓Diversion of transit cargo to inland depots in Nairobi and Naivasha to reduce port-side dwell time.
✓Geofencing of Gate 24 for e-sealed transit exits to streamline the movement of cargo out of the port.

Corridor Risk Factors
The current environment presents multiple layers of risk that threaten the predictability of the Northern Corridor.
!Unpredictable vessel schedules and extended berth delays impacting time-sensitive export cut-offs.
!Increased dwell times for South Sudan-bound cargo due to agent avoidance of the disputed levy.
!Stretched truck turnaround cycles affecting the availability of transport for regional importers.
!Potential for retail stock-outs as festive-season goods remain trapped in the port or inland depots.
!Fragmented visibility between port, customs, and transit agencies preventing a unified response.
Long-form analysis
Navigating the Peak-Season Congestion and Policy Gridlock
The Anatomy of the Congestion
The current congestion at Mombasa is not an isolated event but a result of compounding pressures. With 28 vessels waiting to berth and a heavy pipeline of 56 ships expected in the next fortnight, the port is operating at the edge of its capacity. The influx of spillover cargo from Dar es Salaam has effectively erased the buffer capacity usually available during the peak season.
This has forced a shift in operational strategy, moving cargo from the port to inland depots and CFSs. While this clears the immediate yard, it introduces new complexities for importers who must now manage logistics across multiple inland locations.
The South Sudan Levy Dispute
The USD 5,000 security levy on Juba-bound containers has transformed a logistical challenge into a governance crisis. By creating a financial barrier that agents are actively avoiding, the levy has caused hundreds of containers to pile up, effectively creating a 'dead zone' in the port yard.
This dispute highlights the fragility of transit corridors when charges are perceived as discriminatory or poorly communicated. When cargo becomes a liability due to unpredictable costs, the entire flow of the corridor is disrupted, regardless of port efficiency.
- Agent Avoidance: Logistics providers are shunning Juba-bound cargo to avoid the financial risk of the levy.
- Yard Distortion: Accumulated containers are occupying critical space, slowing down the processing of other cargo.
- Regional Tension: South Sudanese authorities have raised concerns regarding the fairness of the charge compared to other markets.
- Dwell-Time Impact: The dispute directly contributes to longer container stays, increasing costs for the entire supply chain.
The Need for Corridor Redundancy
The current situation reveals a fundamental weakness in East African trade: the lack of a unified, regional operating system. When one gateway fails, the substitute is quickly overwhelmed because port, customs, and transport capacity are managed in silos.
For shippers, the lesson is clear: reliance on a single corridor without contingency planning is a major vulnerability. Predictability is now the most valuable commodity in the region.
Strategic Outlook for 2026
Moving forward, stakeholders must shift from reactive firefighting to proactive corridor management. This requires transparent, real-time data on vessel queues and a collaborative approach to resolving transit charges.
The goal for the next 60 days should be the establishment of a 'control-tower' view that allows all participants to anticipate bottlenecks before they manifest as full-scale supply chain failures.
Call to Action / Integration: How to use this immediately
For Exporters and Manufacturers
- Incorporate a 10-14 day dwell-time buffer into all December-January delivery commitments.
- Pre-clear all documentation to minimize time spent in port-side processing.
- Prepare proactive buyer communication templates that explain current port status with supporting data.
For Forwarders and Logistics Providers
- Document all instances of levy-related cargo delays to support future liability claims.
- Monitor gate-exit and e-seal processing status daily to identify potential bottlenecks early.
- Provide clients with daily advisory updates rather than waiting for service-level complaints.
