Setting Up a Cashew Nut Factory in Tanzania
Tanzania is a major East African cashew grower that exports much of its crop raw. Local processing plants can capture that value and create jobs at origin.
Tanzania is one of Africa’s largest raw cashew nut producers, yet historically exports much of its crop unprocessed. Building processing factories in Tanzania keeps the value — and the jobs — at origin. A Tanzanian plant needs the same essentials as any modern line: raw-nut supply (strong locally), a building with power, water and shell-fired energy, the right machinery and automation level, labour and financing. TTQ supplies, installs and supports plants across Africa, and can revive idle Tanzanian factories as well as build new ones.
Tanzania is one of Africa’s largest cashew producers and one of the most volatile. Output swung from 233 thousand tonnes in 2020 down to 189 by 2023 and back up towards 425 in 2025 estimates — swings that track the auction system and the weather more than they track what is growing in the ground. Anyone sizing a plant on a single year’s figure will size it wrong.
The warehouse receipt system
Tanzania sells its cashew through a warehouse receipt system: growers deliver to registered warehouses through primary cooperative societies, and the crop is sold at auction rather than farm gate. It is the single most important thing to understand before planning a plant there, because it determines how you buy, when you buy, and at what price.
You buy at auction, not at the farm
raw nuts are bought through the auction process against warehouse receipts. Direct farm-gate buying is constrained, so a plant’s sourcing plan is an auction participation plan.
Prices are set in public
the system was designed to give growers price transparency, and it does. The consequence for a processor is that input cost is visible and competitive rather than negotiable in private.
Timing is fixed
the marketing season runs roughly October to January. Buying happens in that window whether or not your working capital is ready.
The rules change
the system has been reformed repeatedly. Verify the current arrangement with the Cashewnut Board before committing capital — this is not a page to plan a purchase from.
Who you will deal with
| Body | What it covers |
|---|---|
| Cashewnut Board of Tanzania (CBT) | Regulates the cashew industry, the warehouse receipt system and export licensing. The first call for anyone planning to process there. |
| Tanzania Investment Centre (TIC) | Investment registration and the certificate of incentives available to qualifying projects |
| Tanzania Revenue Authority (TRA) | Tax, and the duty treatment of imported processing machinery |
| Tanzania Bureau of Standards (TBS) | Product standards and certification for food processing |
| Primary cooperative societies (AMCOS) | The grower-level organisations that deliver into the warehouse system |
Confirm current terms with the CBT and TIC directly. The regulatory arrangement around Tanzanian cashew has changed more than once and second-hand summaries date quickly.
Why plants stall here, and what fixes it
Tanzania has more idle and under-performing cashew capacity than almost anywhere. The causes are consistent and they are engineering problems rather than market ones — mismatched machinery, steam that cannot hold 3–4 bar under load, no humidification ahead of peeling, and spares eight weeks away. Reviving an existing plant is usually faster and cheaper than building new, because the building and the power connection already exist. See cashew project revival in Africa for the assessment process.
What a Tanzanian plant needs
Power that tolerates the grid
380V 3-phase with inverter compressors that ride through voltage fluctuation, plus shell-fired steam so the heat load does not depend on the grid at all.
A sourcing plan, not a supplier
auction participation, warehouse relationships and the working capital to buy inside the October–January window. This is the part that decides capacity.
Spares you can hold
wear items sized so a realistic kit fits in a cupboard. Main knives, cups, brooms and peeling knives are what actually stops a line — see spare parts.
Training that sticks
commissioning on local nuts rather than a demonstration batch, and operators trained on the settings rather than shown them once.
If there is a stalled plant in your region, assess it before costing a greenfield. The building, the power connection and often the workforce are the slow expensive parts, and they may already be standing. Tell us what is there and we will tell you what can be saved.
