Tanzania's Dar es Salaam Port: The Gateway for Rwanda, DRC, Zambia, and East Africa's Landlocked Nations

Why Dar es Salaam Is Unavoidable for Central and East African Trade#

Tanzania's Dar es Salaam port handles the imports and exports of six landlocked nations: Rwanda, Burundi, the Democratic Republic of Congo (eastern DRC in particular), Zambia, Uganda, and parts of Malawi. These countries have no coastal access and are geographically channelled toward the Tanzanian coast through the Central Corridor (serving Rwanda, Burundi, and DRC) and the TAZARA corridor (serving Zambia and Malawi via railway). For businesses trading in these markets, Dar es Salaam is not an option — it is a necessity for most cargo flows. Understanding its operational realities — port congestion, dwell times, customs processes, and transit documentation requirements — is essential for planning realistic delivery timelines.

Historical Congestion and Its Cost Impact#

Dar es Salaam has historically been one of Africa's most congested ports. Container dwell times — the period a container spends in the port from vessel discharge to gate-out — have at various points averaged 12-20 days, compared to 3-5 days at efficient ports. Congestion costs are not abstract: each additional day a container sits in the port incurs demurrage charges (from the shipping line for delayed container return) and port storage fees, which compound daily. For cargo transiting through to a landlocked destination, additional delays at border crossings and clearing customs in the transit country add further cost. A 20-day port delay on a 40-foot container carrying £50,000 of goods can add £1,500-3,000 in demurrage and storage charges alone, before accounting for the cost of delayed delivery to the end customer.

The TAZARA Railway and Central Corridor#

Two main transport corridors connect Dar es Salaam to the landlocked interior. The TAZARA (Tanzania-Zambia Railway Authority) railway was built by China in the 1970s and runs 1,860km from Dar es Salaam to Kapiri Mposhi in Zambia, with connections to the Zambian copper belt and onward to Zimbabwe and South Africa. The railway has suffered from chronic underfunding, deferred maintenance, and capacity constraints, limiting its practical throughput. The Central Corridor runs from Dar es Salaam by road through Tanzania to Rwanda, Burundi, and eastern DRC, covering approximately 1,600km to Kigali and 2,100km to Bujumbura. Road transport dominates because of railway limitations, though transit times are long — typically 5-8 days to Kigali under normal conditions.

SGR Investment and the Changing Infrastructure Picture#

Tanzania has committed significant investment to a Standard Gauge Railway (SGR) that will ultimately connect Dar es Salaam to Rwanda, Burundi, and Uganda. The first phase — Dar es Salaam to Dodoma (the capital) — opened in 2023 and achieved 300km of the planned 1,700km total route. The SGR, when complete, will fundamentally reduce transit times and costs for landlocked countries: modern rolling stock and higher speeds will cut Dar es Salaam-Kigali transit times from 5-8 days by road to potentially 2-3 days by rail. The Tanzania Ports Authority has also invested in container handling equipment and yard management systems at Berths 1-7 to improve throughput. These investments are gradually reducing dwell times, though Dar es Salaam remains slower than world-class benchmarks.

Practical Implications for Importers and Exporters#

For UK exporters shipping goods to landlocked East and Central African markets, the practical advice is to build transit time buffers into customer delivery commitments: promise your customer delivery in 8-10 weeks when the theoretical supply chain is 6 weeks, to absorb port and border variability without missing commitments. Use a clearing agent in Dar es Salaam with a strong track record — local relationships with Tanzania Revenue Authority customs officials and Tanzania Ports Authority management matter significantly for clearing speed. Ensure your shipping documents are 100% accurate before the vessel sails, because document errors cause disproportionate delays at Tanzanian customs. For time-sensitive goods, consider whether airfreight through Kilimanjaro International Airport or Entebbe in Uganda might be cost-justified. AskBiz tracks your shipment timelines and landed costs for East African routes and flags automatically when transit patterns suggest emerging delays.

• Dar es Salaam is the primary port for six landlocked African nations.
• Its congestion has historically added weeks to transit times, but SGR railway investment and the Central Corridor development are gradually improving throughput.
• Understanding the port's dynamics is essential for any business importing to or exporting from East and Central Africa.
