Two Ports, One Region, Many Stakes

East Africa’s economic integration is increasingly playing out along its transport corridors. At the center of this race lie two coastal titans: Kenya’s Port of Mombasa and Tanzania’s Port of Dar es Salaam. While both serve as critical trade arteries for the region’s landlocked economies, Rwanda, Uganda, Burundi, and the DRC, the question has now sharpened: which port will define East Africa’s trade future?

Mombasa has long dominated, bolstered by mature systems and institutional trust. But Dar es Salaam is mounting a credible challenge. With billions invested in physical upgrades, a new dry port at Kwala, and a Standard Gauge Railway (SGR) meant to link sea to hinterland seamlessly, Tanzania is repositioning its port as a regional logistics hub. Still, infrastructure alone may not be enough.

This article interrogates the evolving port rivalry, not through headlines or press statements, but through complex trade data, logistics behavior, and the strategic calculus shaping East Africa’s trade decisions. The stakes are high: beyond cargo and customs lies a broader contest over regional leadership.

The Competitive Edge,  Where Dar Is Catching Up

Until recently, Dar es Salaam lagged behind Mombasa in nearly every operational metric, berth occupancy, ship turnaround time, and cargo dwell time. But since 2022, the Tanzanian government has prioritized port reform as a national economic lever. The result is tangible.

The modernization of Dar Port, backed by a $420 million investment under the Dar es Salaam Maritime Gateway Project (DMGP), has expanded capacity through deeper berths, container yard expansions, and faster cranes. Moreover, the newly launched Kwala Inland Container Depot (ICD) and the SGR’s phased rollout promise to decongest the city port by transferring cargo directly to the hinterland.

These developments are not cosmetic. Compared to Mombasa’s already congested container yards, Dar’s inland port design and digital systems offer long-term scalability. The logic is simple: build a bigger pipe and move cargo faster, not just at the dock but across the chain.

Furthermore, Tanzania’s strategic location gives Dar an edge in serving southern EAC and SADC countries. For cargo heading to Burundi, southern DRC, Zambia, and Malawi, Dar is not just a rival to Mombasa, it is geographically and commercially preferable.

Mombasa’s Retained Dominance, Institutional Lead, and Private Sector Trust

Despite Dar’s infrastructure surge, Mombasa remains the default port for most East African transit traders. This isn’t only about efficiency, it’s about predictability.

Mombasa processed over 41 million tonnes of cargo in 2024 compared to Dar’s 18 million. More importantly, its ship turnaround averages 1.25 days, while Dar still struggles with delays of up to 5–7 days under peak pressure, occasionally spiking to 25 days.

What keeps shippers coming back to Mombasa isn’t the cranes, it’s the clarity. Kenyan port agencies work in a relatively synchronized manner. Customs clearance, port health, and KRA systems are deeply integrated, with minimal discretion at checkpoints. Private sector players, mainly from Uganda and Rwanda, have built decades-long logistical habits around this institutional consistency.

Tanzania’s challenge, therefore, is not just to match infrastructure, but to build institutional trust. Infrastructure may attract attention, but efficiency earns repeat business.

Corridor Shifts: What the Traffic Data Shows

Trade flows tell a clearer story than policy speeches. Despite Dar’s investment push, Mombasa continues to handle the lion’s share of regional cargo. In 2024, the port moved over 1.6 million TEUs, while Dar struggled to hit half that. Uganda remains Mombasa’s top transit customer, and even Rwanda, geographically closer to Dar, still routes nearly 70% of its imports via Kenya.

Part of this inertia is behavioral: freight forwarders, insurance agents, and clearing houses have built logistics ecosystems around Mombasa. But another part is performance-based. The Central Corridor, which feeds into Dar, is perceived as slower, less predictable, and vulnerable to discretionary enforcement, particularly at weighbridges and border posts.

That said, the trend is not fixed. The Kwala Dry Port, newly operational and linked to the SGR, has begun absorbing container volumes previously clogging Dar port roads. If the SGR scales entirely to Mwanza and Kigoma, Dar could claw back DRC-bound cargo that currently goes through Mombasa–Kampala–Kasese. The corridor game is dynamic, and Tanzania’s investments are shifting the equation.

Pricing, Politics, and Policy: The Under‐the‐Radar Game

While public focus remains on infrastructure, much of the competitive action lies in pricing and regional diplomacy.

Surprisingly, Mombasa is often more expensive than Dar es Salaam, by up to $1,200 per container in some cases. Yet, shippers are willing to pay the premium for speed, regulatory consistency, and fewer surprise charges. Dar’s cost advantage is blunted by informal payments, slower document processing, and perceived inefficiencies in truck offloading at port terminals.

Then comes the political layer. Kenya and Uganda have long had tight infrastructure alignment, with Uganda even investing in Kenyan oil and rail assets. Meanwhile, Tanzania’s push toward SADC integration has meant less diplomatic engagement with EAC port users like Rwanda and Uganda. Rwanda’s flirtation with a rail link to Kenya and the Northern Corridor reflects lingering concerns over Dar’s institutional reforms.

Policy coordination, or lack thereof, plays a decisive role in cargo routing. Ports are national assets, but corridors are regional ecosystems. Unless Tanzania’s port, customs, and rail institutions speak with one voice, policy misalignments will undermine Dar’s commercial attractiveness.

What Dar Must Get Right: Beyond Concrete and Cranes

Dar es Salaam’s port modernization is a bold step. But to truly compete with Mombasa, the next leap must be institutional.

Digital upgrades must be accompanied by end-to-end data sharing across port, customs, and SGR systems. Customs reforms must eliminate redundant clearance steps, harmonize valuation, and improve cargo dwell times. Logistics associations, often excluded from reforms, must be involved early to ensure operational workability.

Above all, Tanzania must invest in reputation capital. For shippers, reliability is king. That means consistent processing times, predictable port charges, and clear communication in the event of disruptions. A cargo owner choosing between Dar and Mombasa is not just selecting a location, they are deciding between two systems of trust.

For Dar to win, it must offer more than cheaper tariffs or shorter routes. It must become a trusted logistics partner for the region.

Winning the Corridor Game

Dar es Salaam’s transformation is one of the most ambitious port modernization efforts in Africa today. The cranes are taller, the berths are deeper, and the dry ports are expanding. Yet, the battle for regional cargo supremacy will not be won on infrastructure alone. It will be won in boardrooms where freight decisions are made, in the reliability of digital clearance systems, and the lived experiences of cargo owners navigating the corridor.

Mombasa still holds the advantage, mainly because it has mastered the soft power of logistics: predictability, trust, and institutional coordination. But Dar is closing in. Suppose Tanzania can match physical upgrades with institutional maturity, transparent pricing, real-time cargo tracking, seamless customs integration, it will not just challenge Mombasa. In that case, it may redefine regional trade routes altogether.

The Central Corridor’s future depends not just on roads, rails, and ports, but on the confidence it inspires across borders. For Tanzania, the challenge is no longer whether it can build. It is whether it can deliver consistently, competitively, and credibly.
