Cashew Nuts from Tanzania: A Guide for Buyers

Tanzania is one of Africa's notable cashew origins, and the crop has long been an important part of the country's agricultural export story. For a wholesale or export buyer, cashew can look deceptively simple — a familiar snack nut — but the trade has its own vocabulary, its own quality metrics and its own decision points. This guide walks through what matters when sourcing.

Tanzania as a cashew origin

Cashew (Anacardium occidentale) grows on evergreen trees suited to warm, tropical lowlands with a defined dry season, and southern Tanzania in particular has a long heritage with the crop. Much of it is grown by smallholders, which is why aggregation through a farming and outgrower network is central to putting together commercial quantities of consistent quality.

Buyers should understand the crop is seasonal: trees flower and set fruit on an annual rhythm, and the raw harvest is concentrated into a buying window. Planning around that calendar is part of sourcing well.

RCN versus kernels

The first fork in the road for any buyer is the form of the product.

• Raw Cashew Nuts (RCN): the whole nut in its shell, as it comes from the farm after drying. RCN is traded in large volumes and is the input for processors. Its quality is judged largely on nut count per kilogram and on out-turn.
• Kernels: the edible nut after the shell and testa (skin) have been removed through processing. Kernels are what most food buyers, packers and retailers actually want, and they command the grading system most people picture when they think of cashew.

Deciding between RCN and kernels shapes everything else — price basis, processing responsibility, packaging and shelf life.

Processing, out-turn and grading

Turning RCN into clean kernels is a careful sequence: conditioning and steaming or roasting to loosen the shell, shelling, drying, peeling off the testa, and then grading. The shell contains a caustic oil, so processing is a skilled operation.

A few terms recur in every serious cashew conversation:

• Out-turn: a measure of how many usable kernels a batch of RCN yields, often expressed as pounds of kernel per 80 kg bag (commonly discussed as an out-turn number). Higher out-turn means better value in the raw nut and is a headline quality metric for RCN.
• W-grades: whole white kernels are graded by count per pound — for example W180, W210, W240, W320 and so on. A lower number means larger nuts and fewer per pound; a higher number means smaller kernels. Buyers pick grades to suit their use, from premium whole nuts to bulk ingredients.
• Colour and scorch grades: beyond pure white, there are scorched and lightly discoloured grades that are perfectly good for many applications at a better price.
• Splits and pieces: kernels that break during processing are graded as butts, splits, large white pieces (LWP), small white pieces (SWP) and so on. These are ideal for baking, confectionery, cashew butter and ingredient use where whole appearance is not essential.

Matching grade to end use is where buyers save money: paying for W240 wholes when the product goes into a paste is simply overspending.

How wholesale and export buyers source

Sourcing cashew well comes down to being specific and being organised:

• Write a clear specification: grade, moisture, count, acceptable defect tolerances and packaging.
• Agree the quality basis: for RCN, out-turn and nut count; for kernels, grade breakdown and defect limits.
• Confirm packaging and shelf life: kernels are often vacuum-packed in tins or lined cartons to protect them from moisture and rancidity; RCN travels in breathable jute bags.
• Plan around the season and documentation: align orders with the harvest window and confirm who arranges export paperwork.

We source raw material through our farming and outgrower network, grade and pack to specification, and can arrange export documentation and cold-dry handling appropriate to the product.

A practical checklist

Before you commit, make sure you can answer:

• Am I buying RCN or kernels, and who carries the processing?
• Which W-grades, splits or pieces actually fit my product?
• What are my moisture and defect tolerances?
• How will the goods be packed for the distance they travel?
• Does my timeline fit the harvest calendar?

Get those five right and cashew becomes one of the more straightforward lines to source from Tanzania — a durable, storable, high-value product with a well-understood grading language that lets buyer and supplier speak precisely about quality.
