The Groundnuts that slipped past SADC’s invisible Borders

A small fix at a forgotten border post reveals how Southern Africa is quietly rewriting the rules of regional integration.

By Collins Mtika

At the Songwe Border Post, where Malawi meets Tanzania, and where trade too often stops dead, Yedwa Martin Mhango faced a problem that should never have existed.

His company, H Adam Agro, was shipping some of Africa’s best groundnuts to Kenya, sealed by Malawi Revenue Authority inspectors, cleared, and ready to go.

Yet at the border, exporters were ordered to offload and reinspect every container, even though the consignments had already been vetted and sealed at origin.

“A day or two at the border. That’s what we were losing,” Mhango recalls. Each delayed truck cost about MWK 1 million.

Over a year, across five exporters using the same corridor, that meant nearly MWK 180 million quietly absorbed by the inefficiency of one duplicated procedure.

What sounds like a small administrative nuisance was, in fact, a window into the invisible barriers that have haunted regional trade in Southern Africa for decades.

And Malawi’s solution offers a rare, concrete glimpse of how the Southern African Development Community (SADC) is finally beginning to dismantle them.

In June 2025, through coordinated action by the SADC Secretariat, the German government via GIZ, and local customs authorities, the duplication was eliminated.

The resolution was not revolutionary. It was almost mundane: recognise sealed consignments across borders, honour each nation’s regulatory integrity, and stop treating previously cleared goods as suspects.

Yet its ripple effects spread across the entire system of regional integration — exposing both the persistence of trade friction and the growing momentum to resolve it.

Agriculture is SADC’s lifeblood. In a region where rural populations exceed 60 per cent, and farming underpins millions of livelihoods, intraregional agricultural trade should be a natural engine of growth.

Instead, it has been choked by tariffs, non-tariff barriers, inconsistent standards, roadblocks, and bureaucratic friction, friction that costs exporters time, money, and competitiveness.

Malawi, in particular, has long positioned itself as an agricultural exporter. Groundnuts, tobacco, pulses, and maize form the backbone of that economy.

Yet the country has struggled to translate production volumes into regional market share. The reason is blunt: it costs too much and takes too long to move goods across borders.

Dr Bertha Bangara-Chikadza, President of the Economics Association of Malawi, articulated the challenge during the SADC Summit in August 2025.

SADC nations, she noted, often create barriers among themselves — “and as such we end up exporting outside Africa, but we have untapped regional potential.”

The irony is stark. Malawi buys heavily from South Africa: fertilisers, machinery, fuel. South Africa needs regional markets. Kenya imports what Malawi already produces. Tanzania shares a border and a complementary economy with Malawi.

Yet trade between these neighbours remains fractional because the machinery of regional commerce keeps breaking down.

The groundnut re-inspection requirement, introduced by Tanzania in October 2024, was a classic non-tariff barrier (NTB). Ostensibly it was meant to verify quality and compliance.

On paper, the rationale made sense. The execution did not.

Exporters began to distrust the regulatory process altogether. Borders became points of suspicion. Goods already cleared faced fresh inspections. Seals were broken.

The toll, psychological and operational, was immense.

In May 2025, H Adam Agro formally reported the barrier at an AfCFTA/NTB training workshop organised by the SADC Secretariat, CESARE, the Malawi Ministry of Trade and Industry, and the AU AfCFTA Support Programme.

The registration triggered a process. CESARE and the SADC Secretariat convened high-level stakeholders, customs officials, private-sector representatives, and NTB administrators within a month.

What followed was not confrontation but constructive dialogue. The parties recognised a simple truth: regulatory trust was more efficient than suspicion. Within weeks, Tanzanian and Malawian authorities committed to restoring the integrity of sealed consignments.

The result was immediate and tangible. H Adam Agro now saves more than MWK 3 million per month (about EUR 1,500). Trucks cross Songwe in hours, not days. Groundnuts arrive fresher. Consumers receive cleaner, higher-quality products.

And farmers, supported by exporters, are paid faster and gain stronger access to regional markets.

The groundnut resolution matters not because groundnuts are vital to global commerce; they are not, but because it exposes three deeper truths about regional integration in SADC.

First, mechanisms work when resourced and activated. The AfCFTA NTB Reporting Platform exists. The SADC Secretariat has convening power. CESARE, funded by Germany and the European Union, provides technical and diplomatic capacity. What was missing was political will. Once activated, the tools worked exactly as intended.

Second, most barriers are bureaucratic, not malicious. Tanzania was not punishing Malawi; it was guarding regulatory autonomy. The cost of inefficiency was simply spread across many actors, hidden from decision-makers. Once the irrationality became clear, change followed quickly.

Third, agriculture is where regional integration delivers results fastest. Manufacturing requires capital and long-term coordination. Agriculture responds instantly to barrier removal. When groundnuts reach Kenyan buyers faster, Malawian farmers plant more. When margins improve, Tanzanian traders move higher volumes. The multiplier effects move quickly through rural economies.

Dr Bangara-Chikadza frames this in terms of comparative advantage: “Those who can produce something cheaply should be allowed to produce.”

This means Malawi should lead regional exports of groundnuts and pulses. It means South Africa should focus on industrial goods.

And it means the region must shift toward specialisation rather than duplication, the mechanism that actually generates regional wealth.

The groundnut breakthrough comes within a broader institutional push.

In August 2025, Madagascar’s President Andry Rajoelina assumed the SADC Chair, while Malawi’s former President Lazarus Chakwera became Chair of the Organ on Politics, Defence and Security Cooperation.

Botswana’s President Duma Boko has called for deeper integration and simpler customs procedures, arguing that the region must eliminate roadblocks and corruption that slow trade flows.

Statements like these signal political commitment that reaches the highest levels of decision-making.

CESARE, the German-EU-funded initiative behind the groundnut resolution, represents a larger investment in regional architecture. Its Trade Component works systematically to reduce barriers, improve customs procedures, and strengthen competitiveness.

The initiative supports the SADC Protocol on Trade and helps make the AfCFTA a functioning reality.

For Malawi, this positioning is strategic: it is neither a regional powerhouse like South Africa nor a transport hub like Tanzania. It competes through efficiency, agriculture, and labour exports.

Regional integration strengthens Malawi’s hand by opening markets for its produce and allowing its workforce to access better-paying jobs across SADC.

Dr. Bangara-Chikadza highlights a dimension often overlooked: labour mobility.

Malawi exports labour. Workers in South Africa, Botswana, and elsewhere send remittances home that dwarf official development assistance and significantly bolster household incomes.

Yet formal labour agreements within SADC remain limited. With genuine free movement of labour, Malawi would benefit immediately through expanded opportunities and stronger remittance flows.

This interconnection between goods trade, services trade, and labour mobility shows that regional integration is not a single lever but an interdependent system. Pull one thread, and others move.

Remove a barrier, and exporters invest in technology and training. Expand mobility, and migrants return with skills and capital. Lower trade barriers, and SMEs begin competing regionally rather than nationally.

Germany’s investment in SADC trade integration reflects a clear strategic calculation about Africa’s future.

By supporting efficient, rules-based trading systems, Germany helps create opportunities for African exporters and lays the foundations for fairer partnerships between Africa and Europe.

This is not charity; it is enlightened self-interest. A more integrated SADC is a more stable region and a more reliable trading partner.

The groundnut story carries clear geopolitical implications. It signals that African nations, with external support, can solve their own integration challenges through dialogue and institutional innovation.

It shows that many barriers are removable rather than structural.

And it demonstrates that when SADC member states prioritise collective benefit over narrow advantage, progress can be rapid and substantial.

Today, Yedwa Martin Mhango’s company moves groundnuts across Songwe with minimal delay. Farmers supply exporters with confidence that goods will reach Kenyan and other regional buyers quickly.

Consumers in East Africa eat fresher groundnuts. And regulators and traders across SADC have learnt a simple lesson: mutual recognition, when implemented, benefits everyone.

This is not a transformational narrative of sudden prosperity. Rather, it is a story of systems working slowly, incrementally, and genuinely.

As Mhango summarised, “Resolving this NTB means a lot to our business because now we have faster access to our destination markets without spending a day or two at the border. It has reduced our costs and ensures fresher, safer groundnuts for our customers. This resolution is a game changer for our business and the thousands of farmers we support.”

In the language of development, it is modest. In the language of Southern African agriculture and regional integration, it is profound.

The groundnuts crossed the border. The barriers came down.
And SADC’s quiet revolution has one unmistakably tangible victory.
