Kenya Needs 540,000 Tonnes of Maize. Why Is Zambia Supplying It Instead of Tanzania?

Kenya is preparing to import up to 25 million 90 kilogramme bags of maize after drought and unreliable rainfall reduced production in several of its major growing areas. Against that backdrop, Zambia has just secured a contract to supply 540,000 tonnes of white Grade A non GMO maize to Baita Trading Company Limited, a Kenyan private sector buyer. The shipment will be delivered in six batches, with the agreement providing an immediate commercial outlet for part of Zambia's record harvest of more than 5.1 million tonnes. For Zambia, the transaction is a significant agricultural export opportunity. For Kenya, it provides another source of grain at a time when domestic supply is expected to fall short of consumption. But for East Africa, there is a more revealing question sitting underneath the transaction: why is a Kenyan buyer sourcing such a large volume from Zambia when Tanzania, its immediate southern neighbour, is itself a major maize producer and has historically been one of Kenya's principal sources of imported maize? The available evidence does not establish that Kenya rejected a Tanzanian offer in favour of Zambia, nor does the Baita Trading agreement say that Tanzania was considered for the contract and lost it. That distinction matters. The buyer is a private company, not the Kenyan government, and the contract is based on prevailing regional market conditions. What the transaction does reveal, however, is a broader competitive question about African agriculture. Kenya clearly has a large and immediate demand for maize, Zambia has demonstrated that it can assemble a very large exportable surplus and a private Kenyan buyer has been able to structure a 540,000 tonne transaction with Zambia. Tanzania has the geographical advantage, a substantial production base and an established history of supplying Kenya, yet the current opportunity has been captured by a producer much farther away. The interesting issue is therefore not whether Zambia has suddenly become a better maize producer than Tanzania. It is whether Zambia has become better at turning a maize surplus into a large, predictable commercial shipment when a buyer needs it. Zambia Has Turned A Harvest Into A Commercial Offer The strength of the Zambian position begins with the scale of its surplus. The country produced more than 5.1 million tonnes of maize in the 2025/2026 farming season, leaving substantial quantities available beyond domestic consumption. Government officials have made clear that the strategic objective is now to find markets for this surplus, with Zambia targeting annual maize production of 10 million tonnes by 2031. Agricultural exports exceeded US$1.1 billion in 2025, compared with US$967 million in 2024, and officials expect the Kenyan maize transaction to contribute to further growth in agricultural export earnings. The significance of this is that Zambia is beginning to treat agricultural production and agricultural market access as two parts of the same economic strategy. Producing more maize without knowing where the additional grain will be sold creates a storage and pricing problem. A bumper harvest can push domestic prices down, increase the amount of grain the state has to purchase or store and expose farmers to weak prices at the very moment they have produced more. Export markets change that calculation because they allow additional production to be absorbed outside the domestic market. The Baita Trading agreement appears to have been built around precisely that opportunity. The company had already indicated in August that it was ready to purchase 10.8 million bags from Zambia, equivalent to roughly 972,000 tonnes using the standard 90 kilogramme bag, with additional requirements potentially following. The immediate contract now covers up to 540,000 tonnes. This suggests that the transaction was not simply a government announcement looking for a buyer after the harvest. There was a commercial buyer with an identified requirement actively looking for grain and a Zambian surplus large enough to satisfy it. That ability to present a buyer with a large, identifiable quantity is increasingly important in agricultural trade. International and regional food buyers do not purchase production statistics. They purchase specific quantities that meet particular quality requirements, on defined schedules, under contracts that establish how prices and delivery will be determined. Zambia's current advantage is therefore not simply that it has maize. It is that the country has been able to convert its surplus into a commercial proposition that a Kenyan buyer can contract. Tanzania Has The Geography And The Production This is where Tanzania becomes central to the story. Tanzania is considerably closer to Kenya than Zambia, shares a long land border with it and has an established history of maize trade between the two countries. World Bank trade data show that Tanzania exported 366,391 tonnes of maize in 2024, of which 168,303 tonnes went to Kenya. Kenya was therefore one of Tanzania's most important maize markets, accounting for almost half of Tanzania's formal maize exports by volume that year. Tanzania also has a substantial domestic production base. FAO currently estimates 2026 maize production at approximately 7.3 million tonnes, with total cereal production expected to reach about 12.8 million tonnes. That maize figure is around thirteen times larger than the 540,000 tonnes covered by the new Zambia-Kenya agreement. Tanzania therefore cannot plausibly be described as a country that simply does not have enough maize to compete for large regional markets. It has the production base, the neighbouring market and an established trading relationship. Geography should give Tanzania a significant commercial advantage. Maize grown in Tanzania's northern regions can reach Kenya through established border corridors, while maize from Zambia must travel a considerably longer distance before reaching the Kenyan market. The longer route means additional fuel, trucking, border and handling costs. Under normal market conditions, a Tanzanian supplier should therefore have an opportunity to compete strongly with a Zambian supplier on delivered cost. Yet geography is only one component of delivered competitiveness. A buyer cares about the price of the grain when it arrives at the destination, the certainty that the required quantity will actually be available, the quality specification, the speed of delivery, the documentation required to export it and the likelihood that the rules governing the transaction will remain stable throughout the contract. A shorter distance can be outweighed by uncertainty if the buyer cannot confidently secure the grain. That is where Tanzania's agricultural challenge becomes more interesting. Tanzania's Problem May Be Commercialisation, Not Production Tanzania's official trade system requires exporters of food crops to obtain an export permit from the Cereals and Other Produce Regulatory Authority, with the permit issued per consignment and valid for two months. The procedure itself is not necessarily prohibitive, and the government has been working to improve trade facilitation. But the existence of a permit system means that agricultural exporters operate within an administrative process that can affect the timing and certainty of commercial shipments. This becomes particularly relevant when compared with the history of Tanzania's maize exports to Kenya. A USDA assessment of Kenya's grain market found that Kenyan traders had historically sourced most imported maize from Tanzania but had increasingly turned to Zambia and South Africa after Tanzania introduced new export procedures. The report specifically identified difficulty obtaining export permissions and noted that Tanzania had previously imposed export bans or restricted access to export permits when domestic supplies were considered insufficient. This history does not mean that Tanzania is currently unable or unwilling to export maize. It does show, however, that agricultural trade is affected by policy predictability. A Kenyan trader deciding where to source hundreds of thousands of tonnes needs confidence that the grain can leave the exporting country when the contract requires it. If export rules can change rapidly because of domestic food security concerns, the buyer faces an additional commercial risk even when the physical maize is available. That risk has an economic cost. If a Kenyan trader can purchase maize from Tanzania at a lower farm or wholesale price but cannot be certain that an export permit will be available at the required time, the apparent price advantage becomes less meaningful. The trader may prefer a more distant supplier if the contract is easier to execute and the quantity is more certain. The extra transport cost then becomes the price paid for supply certainty. This is one of the reasons Zambia's current deal should be read carefully. It does not prove that Zambia is cheaper than Tanzania. It suggests that Zambia has been able to organise a sufficiently large and clearly defined supply for a buyer facing an urgent requirement. Tanzania Has Already Lost Market Share To Zambia Before There is evidence that this is not a completely new development. The USDA reported that Kenya had historically sourced most of its imported maize from Tanzania but that Kenyan traders had begun sourcing more from Zambia and South Africa after encountering difficulties with Tanzanian export procedures. A 2024 study of Tanzania Kenya maize trade likewise found that non tariff barriers had increased transaction costs, including delays at border points, although infrastructure such as one stop border posts and electronic cargo tracking had helped reduce some of those costs. The significance of that history is that the current Zambia deal should not be viewed as an isolated event. Zambia is entering a market in which Tanzania once held a particularly strong position. The competitive environment has changed because Kenyan buyers now have experience sourcing from alternative suppliers, while Zambian producers and traders have demonstrated that they can reach the Kenyan market when domestic supply conditions create an opportunity. The lesson for Tanzania is not that export permits should simply be abolished. A government still has a legitimate responsibility to protect domestic food availability, particularly in years when production falls or prices rise sharply. The more difficult policy question is how to protect domestic food security without creating uncertainty that discourages regional buyers from treating Tanzania as a dependable long term supplier. A country cannot simultaneously tell farmers to produce large commercial surpluses and make it difficult for those surpluses to move into external markets when domestic demand is insufficient to absorb them. Kenya Is Buying Certainty As Much As It Is Buying Maize Kenya's current situation makes this distinction particularly important. The government has estimated that the country consumes approximately 75 million 90 kilogramme bags of maize annually while domestic production could fall short by about 25 million bags because of drought and unreliable rainfall in major producing areas. The government has therefore moved to facilitate imports to prevent a shortage and limit price pressure on consumers. When a country has a deficit of that scale, buyers need volume. They also need speed. A miller or grain trader cannot solve an immediate supply shortage by purchasing small quantities from thousands of farmers one transaction at a time. The commercial system must aggregate those quantities into shipments large enough to move efficiently across borders. That is precisely where the structure of Zambia's agreement becomes significant. The contract covers up to 540,000 tonnes, is divided into defined shipments and specifies Grade A white non GMO maize. Pricing will be determined at the start of each shipment according to prevailing regional market conditions. The buyer therefore has a framework within which it can plan supply, while Zambia has a defined outlet for a significant share of its surplus. Tanzania's agricultural sector needs to compete at this level of commercial organisation if it wants to capture the full value of its production. The question is no longer whether individual Tanzanian farmers have maize to sell. The question is whether Tanzania can aggregate hundreds of thousands of tonnes into a commercially dependable supply without creating uncertainty over permits, quality, documentation, border procedures or delivery schedules. The Border Is Part Of The Product Agricultural competitiveness is often discussed in terms of yield per hectare, seed quality, fertiliser use and farm mechanisation. Those variables matter, but once a country begins producing substantial surpluses, the economics of the sector increasingly depend on what happens after harvest. A tonne of maize sitting in a warehouse in Tanzania is not equivalent to a tonne of maize delivered to a miller in Kenya. The economic value of the latter includes the cost and reliability of storage, aggregation, transportation, border clearance, inspection and final delivery. If any of those stages introduces excessive delay or uncertainty, the competitive advantage created at the farm can disappear before the product reaches the customer. Research on Tanzania Kenya maize trade has found that non tariff barriers, including border delays, have historically increased transport costs. One study identified delays of six to seven hours as a significant source of additional cost for Tanzanian maize exporters, while also finding that one stop border posts and electronic cargo tracking systems could reduce some of the burden. (SCIRP) This means that Tanzania's agricultural policy cannot be separated from its trade and transport policy. Improving seed varieties while leaving exporters to navigate unpredictable border processes produces only part of the desired economic result. The same is true of roads and railways. A good road from a farm to a warehouse has limited value if the grain then sits at a border waiting for documentation. The export product is therefore not just maize. It is maize plus the certainty that the maize can reach the buyer. Tanzania And Kenya Have A Larger Trade Question To Solve The maize issue sits inside a broader effort by Tanzania and Kenya to reduce barriers to bilateral trade. The two countries have been working to resolve outstanding non tariff barriers and have set an ambitious target for expanding bilateral trade. The US International Trade Administration reported in May that Tanzania and Kenya had signed eight new bilateral agreements aimed at economic integration and were targeting the elimination of remaining non tariff barriers by June 30, 2026. The maize market provides a practical test of whether that ambition is translating into commercial reality. Kenya is currently telling its market that it needs millions of bags of imported maize. Tanzania is a large regional producer sitting immediately next door. Zambia is hundreds of kilometres farther away, yet a Kenyan private company has signed a contract for 540,000 tonnes with a Zambian supplier. There is no contradiction in these facts because markets do not allocate business according to geography alone. They allocate business according to the total cost and risk of obtaining the product. If Tanzania can make maize consistently available to Kenyan buyers at competitive delivered prices, its geographical advantage should become economically valuable. If buyers continue choosing more distant suppliers despite the additional logistics costs, Tanzania will need to look closely at what is causing that preference. That is a much more useful question than asking why Zambia has been chosen. The Bigger Risk Is Producing More Without Building The Market Tanzania's maize production is large enough that the country faces a strategic choice. It can continue treating maize primarily as a domestic food security commodity, intervening in exports whenever domestic conditions become uncertain, or it can increasingly treat commercially produced maize as a regional agricultural industry while maintaining mechanisms that protect domestic food availability. The two objectives do not have to conflict. A country can maintain strategic reserves, monitor domestic stocks and retain emergency measures while still providing exporters and regional buyers with clear rules under which commercial trade can take place. The critical issue is predictability. Farmers, traders, millers and foreign buyers all make investment decisions based on expectations about whether markets will remain open. This becomes particularly important if Tanzania wants to increase agricultural production substantially. More production creates economic value only when the market can absorb it. If a farmer knows that a large harvest could result in restrictions on exports, uncertain permits or weak domestic prices, the incentive to invest in higher productivity is reduced. If the farmer knows that regional markets will remain accessible and that commercial buyers can legally move large quantities across borders, the incentive changes. Agricultural production therefore creates its greatest economic effect when it is connected to a reliable market. Zambia's Success Is A Warning And An Opportunity For Tanzania The 540,000 tonne Zambia Kenya deal should not be interpreted as evidence that Tanzania has somehow failed while Zambia has succeeded. Zambia has a major surplus and has found a buyer. Tanzania has its own export markets and exported more than 366,000 tonnes of maize in 2024, including more than 168,000 tonnes to Kenya. There is still substantial room for Tanzania to expand its role in the regional grain market. But the transaction does expose a vulnerability in Tanzania's agricultural model. The country has the land, production capacity and proximity to major food markets, yet its agricultural exports can still be constrained by the institutional and logistical conditions under which those products move. That is especially important because Tanzania's maize production is currently estimated at 7.3 million tonnes, while Zambia has set a target of 10 million tonnes. If both countries continue increasing production, competition for regional markets will become more intense. Kenya, Rwanda, the Democratic Republic of Congo and other food importing markets will increasingly have choices between suppliers. The winning producer will not necessarily be the one with the largest harvest. It will be the producer that can offer the buyer the right quality, price, volume and delivery certainty at the same time. For Tanzania, that means the next stage of agricultural policy should be concerned not only with how much maize the country produces but with how easily that maize can become a regional commercial product. The question raised by Zambia's 540,000 tonne agreement is therefore not simply why Kenya is buying maize from Zambia instead of Tanzania. It is whether Tanzania is making it sufficiently easy for a Kenyan buyer to choose Tanzania when Tanzania has the maize, the geography and the market relationship. Tanzania does not need to produce more maize to become a bigger agricultural power. It needs to make the maize it already produces easier for Africa to buy. FAQ Why is Kenya importing maize in 2026? Kenya expects a maize deficit of approximately 25 million 90 kilogramme bags because drought and unreliable rainfall have reduced production in several major growing areas. Why is Zambia supplying Kenya with 540,000 tonnes of maize? Zambia has produced more than 5.1 million tonnes of maize and has a substantial surplus available for export. Kenya's Baita Trading Company has contracted Zambia's Food Reserve Agency to supply up to 540,000 tonnes of Grade A white non GMO maize. Does Tanzania produce enough maize to supply Kenya? Tanzania's 2026 maize production is forecast at approximately 7.3 million tonnes, and the country exported 366,391 tonnes of maize in 2024, including 168,303 tonnes to Kenya. Why might Kenyan buyers choose Zambia despite Tanzania being closer? The available evidence does not establish the specific commercial reason behind the current Baita Trading contract. However, previous USDA assessments found that Kenyan traders had increasingly sourced maize from Zambia and South Africa after experiencing difficulties with Tanzanian export procedures and permit restrictions. This suggests that supply certainty and trade policy can offset Tanzania's geographical advantage. What is the bigger agricultural lesson for Tanzania? Tanzania's challenge is increasingly about commercialisation rather than simply production. To capture more regional demand, it needs to make large volumes of agricultural produce consistently available to buyers through predictable export rules, efficient aggregation, storage, transport, border procedures and competitive delivered prices.
