Cashew Shelling & Peeling Lines: Tanzania (2026)

A cashew shelling and peeling line in Tanzania serves a market that processes barely a fifth of what it grows. The country produced 528,260 tonnes of raw cashew in 2024/25 and processed only 118,262 tonnes domestically, per the Cashewnut Board of Tanzania. That 410,000-tonne raw-export gap is the buyer pipeline equipment suppliers are chasing.

Why Tanzania is buying shelling and peeling capacity now

The 2024/25 crop earned a record Sh1.52 trillion, about USD 583.7 million, and almost all of that value left the country as raw nuts sold at auction. The Cashewnut Board’s director general Francis Alfred has said the government forecasts 700,000 tonnes in 2025/26 and one million tonnes by 2030/31, as reported by The Citizen. Output is climbing faster than the kilns and shelling halls that would add value to it, so the processing deficit is widening rather than closing.

That is the structural reason a foreign OEM gets an RFQ for a shelling and peeling line out of Mtwara or Lindi. The grower side already works. The conversion side does not, and the policy push behind closing it is explicit: the board wants local processing to reach the majority of the crop by 2030, up from roughly a quarter in 2024/25.

Tanzania currently runs 57 cashew processing factories across Ruvuma, Lindi, Mtwara, Pwani, Singida, Katavi, and Dar es Salaam, but only 36 are operational and 21 sit idle, according to Milling Middle East & Africa. Those two numbers tell a supplier exactly where the work is. The idle plants are recommissioning and retrofit RFQs: shelling sections that jam, peeling stages that break too many kernels, sorters that never arrived. The operational plants are expansion and debottlenecking buyers. The greenfield demand sits inside the Maranje cashew industrial park in Mtwara and the cooperative-union builds feeding it.

What a cashew shelling and peeling line actually has to deliver

A buyer in Newala does not want a catalogue of machines. They want whole-kernel yield, because the price gap between whole white wholes and broken pieces is what pays back the capex. A line that holds 85 to 90% whole-kernel recovery earns far more per tonne than one stuck at 75 to 80%, so every quote gets read against breakage, not against headline throughput.

The line a Tanzanian processor quotes runs in a fixed order. Raw nuts are cleaned and calibrated by size, then conditioned. Steam roasting softens the shell ahead of cutting, with steam preferred over older oil-bath methods because it gives finer temperature control and keeps workers away from the acidic cashew-nut shell liquid. Shelling and cutting machines crack the brittle shell to release the kernel, and this is the stage where breakage is won or lost. The kernels are dried, then go through a brief humidification step, a 30-to-90-second steam or fine-spray exposure that lifts surface moisture so the testa peels cleanly. Skip it or get it wrong and breakage climbs. Peeling removes the testa, optical colour sorters split fully peeled from partly peeled kernels for re-peeling, and finally grading and calibration sort by size, colour, and whole-versus-split before vacuum packing.

For a Tanzanian buyer the load-bearing questions on a line are: what whole-kernel yield does it guarantee, how much manual re-peeling does it still demand at local labour cost, what is the throughput per shift at the moisture levels of locally cured nuts, and what spares lead time can the supplier hold from a Dar es Salaam or Mtwara base. A supplier who answers those four wins on technical fit before price enters the conversation.

The OEM geography for this equipment is narrow. Italian specialist Oltremare builds turnkey cashew plants up to 15,000 and 30,000 tonnes per year of raw input and already runs reference sites across West and East Africa, per its company profile. Indian houses such as JJ Engineers and a cluster of Surat and Mangalore builders supply component machines and mid-capacity lines at lower ticket prices, and several Chinese OEMs offer integrated shelling-to-roasting lines. A Tanzanian buyer typically shortlists across all three origins, which means a foreign supplier is competing on yield guarantees and after-sales reach, not on being the only option in the room.

Named buyers and end-users issuing the RFQs

Cashew procurement in Tanzania does not run through a single ministry tender. It runs through a board, a set of cooperative unions, and a growing list of private processors.

The Cashewnut Board of Tanzania (CBT) anchors the public side. It is completing warehouses at the Maranje cashew industrial park in Mtwara, the flagship build meant to convert Tanzania from raw producer to value-adder, developed with industrial-park operator Arise IIP. Inside Maranje, individual processing factories are procured plant by plant rather than as one mega-contract, so a line supplier quotes each tenant or cooperative directly.

The cooperative unions are real buyers in their own right. Tanecu is bringing factories online in Tandahimba and Newala, and Tamcu, the Tunduru cooperative union, is building its own. Beyond the cooperatives sit the private processors among the 36 operational plants, plus the investors recommissioning the 21 idle ones. TACP secretary John Nkundwanabake has framed the prize bluntly: processing 5,000 tonnes of cashews creates over 1,000 jobs, and shifting exports from raw to processed could lift foreign-exchange earnings by more than 50%. That jobs-and-FX argument is what keeps the procurement budget funded.

The practical takeaway for a foreign OEM is that the buyer map has two layers. The board and the park developer control the infrastructure and the land. The cooperatives and private processors control the line purchases. You sell engineering to the second layer while staying visible to the first.

FX, letters of credit, and how a line gets paid

Cashew processors sit on the export-receipt side of Tanzania’s foreign-exchange equation, which works in a supplier’s favour. The crop brings in hard currency every season, and the Bank of Tanzania moved the shilling to a floating regime in November 2024 under its IMF program. The TZS then appreciated roughly 9.5% against the US dollar over the following year, easing the periodic dollar tightness importers had to plan around in 2023. Suppliers should still budget around confirmed letters of credit and treat USD liquidity as something to schedule, not assume.

For a shelling and peeling line above USD 200,000, the confirmed letter of credit is the default settlement instrument. Local buyers open the LC through Tanzanian banks such as CRDB, NMB, NBC, or Stanbic, and a European or Gulf bank confirms it on larger tickets. A common structure is 10 to 30% advance against a bank guarantee, 60 to 70% against shipping documents under the LC, and 10% retention released after commissioning. Cooperative-union buyers often draw on board-backed seasonal financing, so align the milestone schedule with the harvest-receipt calendar rather than the calendar year. Quoting in EUR is common and frequently preferred for European-origin machinery to avoid double conversion. The confirmed-LC route is the single biggest factor in whether a smaller cooperative can actually transact, so build it into the quote from the first email.

Tender platforms and procurement entry points

The national e-procurement portal is TANePS, run under the Public Procurement Regulatory Authority, and it is where the public side of cashew processing surfaces: Maranje infrastructure packages, board-funded equipment, and any tender touching parastatal money. English is the working language throughout, which removes the translation friction suppliers hit elsewhere in the region.

A large share of cashew-line buying never passes through TANePS, though. The cooperative and private purchases run through the Cashewnut Board, the unions, and processor procurement teams directly. The realistic entry plan is to register and monitor TANePS for the public packages while building direct, named-contact relationships with CBT, Tanecu, Tamcu, and the private processors for everything else. The supplier who shows up already knowing which of the 21 idle plants has a recommissioning budget this season is the one who gets the spec.

Dying conventional channels for cashew-line suppliers

The traditional routes for reaching Tanzanian cashew processors are losing their return.

The Dar es Salaam International Trade Fair (Saba Saba) each July is still a national fixture, but for industrial food-processing OEMs it has drifted toward consumer goods and SME exhibitors. The board and the larger processors rarely walk the floor for shelling-line vendor discovery. A fully loaded stand, counting fit-out, freight, travel, and follow-up, routinely costs USD 400 to 900 per qualified lead, with conversion to a letter of intent well under 5%. The various regional cashew and agro-processing expos add reach but produce introductions, not pipeline.

A Dar-based field representative with cashew-sector knowledge runs USD 5,500 to 11,000 per month all-in once housing, work permit, and vehicle are added. At three to six qualified leads a month, that is USD 900 to 3,700 per qualified lead, and the economics only hold above several million euros of annual Tanzanian revenue. Distributor and trading-house lock-in is the other drag: legacy houses take 15 to 30% margin and rarely run active outbound, leaving specialist shelling and peeling OEMs invisible inside catalogues while processors increasingly want direct engineering contact for yield and warranty reasons. Print trade-magazine advertising no longer reaches the procurement managers, who discover vendors through TANePS notifications, peer engineers on LinkedIn, and English-language search.

FAQ

Who buys cashew shelling and peeling lines in Tanzania?

The Cashewnut Board of Tanzania anchors the Maranje park in Mtwara, while cooperative unions like Tanecu and Tamcu and private processors buy the actual lines. With 528,260 tonnes harvested in 2024/25 and only 118,262 processed at home, the buyer base is expanding fast toward the 2030 target.

How much of Tanzania’s cashew crop is processed locally?

About 118,262 of 528,260 tonnes in 2024/25, roughly a fifth. The remaining 410,000 tonnes were exported raw. Government strategy aims to process the majority of the crop locally by 2030, which is the structural driver behind sustained shelling and peeling line demand.

What whole-kernel yield should a cashew line deliver?

A quality line holds 85 to 90% whole-kernel recovery against 75 to 80% on basic setups. The gap matters because whole white kernels command a premium over broken pieces, so Tanzanian buyers read every quote against breakage rate, not just headline throughput per shift.

How do Tanzanian cashew processors pay for imported lines?

Through confirmed letters of credit for tickets above USD 200,000, opened at banks like CRDB or NMB and confirmed by a European or Gulf bank on larger orders. A typical split is 10 to 30% advance, 60 to 70% against documents, and 10% retention after commissioning, aligned to the harvest-receipt season.

Where are cashew processing tenders published in Tanzania?

Public and parastatal packages, including Maranje infrastructure, surface on TANePS in English. Most line purchases by cooperatives and private processors are bought directly through the Cashewnut Board, the unions, and processor procurement teams, so they do not appear on TANePS.
