Quick answer: The export price for raw cashew nuts from Mozambique typically ranges from $1,100 to $1,400 per ton. While raw exports are common, processing nuts domestically into premium kernels can fetch significantly higher market values, between $4,000 and $8,000 per ton. Vertical integration, which connects producers directly to processing, is the primary method for ensuring profitability in the industry.
Mozambique Cashew Processing: From Raw Nuts to Premium Export
Mozambique is Africa's second-largest cashew producer, holding significant potential to capture higher margins by processing raw nuts domestically instead of exporting them raw. By shifting from raw exportation to local processing, the industry could theoretically triple its value, transforming the economic landscape for the local agricultural sector.
This guide explores the current state of the industry, the technical steps involved in processing, and the economic hurdles faced when moving from raw nuts to premium international exports.
Mozambique Cashew Industry
Production Statistics
| Metric | Value |
|---|---|
| Annual raw cashew production | 140,000 tons |
| Number of cashew farmers | ~1.2 million |
| Cashew trees | ~30 million trees |
| Main provinces | Nampula (40%), Cabo Delgado (20%), Inhambane (15%) |
| Harvest season | October-February |
| Processing rate | 15-20% (80-85% exported raw) |
| Raw nut export price | $1,100-1,400/ton |
| Processed kernel price | $4,000-8,000/ton |
| Kernel extraction rate | 22-25% (100 kg RCN → 22-25 kg kernels) |
The Cashew Value Chain Problem
The current value chain often sees Mozambican farmers provide raw nuts to exporters who ship them to India for processing, where the majority of the value is captured.
Mozambican farmer → Raw nut exporter → Indian processor → Kernel buyer
$800/ton RCN $1,200/ton RCN $5,000/ton kernels $8,000/ton
If Mozambique were to increase its domestic processing capacity, a larger share of the $3,800/ton margin currently captured by foreign processors could remain within the country to support local development and infrastructure.
Cashew Processing: Step by Step
Step 1: Harvesting and Drying
- Harvest: Nuts are gathered from the ground during the harvest period between October and February.
- Drying: Raw nuts must be sun-dried for 2-3 days until they reach 8-9% moisture content.
- Storage: Stored in jute bags within dry, well-ventilated areas to prevent spoilage.
- Quality: Properly dried nuts can maintain quality for 12 months or longer.
Step 2: Steaming/Boiling
- Process: Raw nuts are steamed at 120°C for 20-30 minutes.
- Purpose: This softens the tough outer shell for easier cutting and reduces the presence of caustic cashew nut shell liquid (CNSL).
- Equipment: Requires industrial steam boilers, often costing between $10K and $50K.
Step 3: Cutting (Shelling)
- Manual: Workers use specialized knives, achieving 8-10 kg per day.
- Semi-mechanized: Foot-pedal machines can increase output to 20-30 kg per day.
- Fully mechanized: Automatic shelling lines can process 500-2,000 kg per day.
- Challenge: Preventing kernel breakage is critical, as broken pieces command prices up to 50% lower than whole kernels.
- Equipment: Semi-mechanized shellers ($2K-5K) or automatic lines ($50K-200K).
Step 4: Drying Kernels
- Process: Kernels are dried in hot air ovens at 70°C for 6-8 hours.
- Purpose: This reduces residual moisture and allows the testa (the thin brown skin) to be removed more easily.
- Equipment: Industrial hot air dryers typically range from $5K to $20K.
Step 5: Peeling (Testa Removal)
- Manual: Hand-peeling yields 5-8 kg per worker per day.
- Mechanized: Automatic peeling machines can process 200-500 kg per day.
- Quality: Whole, intact, peeled kernels are essential for fetching premium prices on global markets.
- Equipment: Specialized peeling machinery ranges from $20K to $80K.
Step 6: Grading
- International grades:
- W240 (240 kernels/pound) — Represents large, premium quality.
- W320 — The standard medium market size.
- W450 — Small kernels.
- Broken — Pieces resulting in significantly lower market value.
- Equipment: Vibrating sieve graders ($3K-15K) or manual sorting methods are used.
Step 7: Packaging
- Vacuum-sealed: Product is packed in 50lb (22.7kg) cartons using a nitrogen flush to displace oxygen.
- Shelf life: Vacuum-packed products last up to 12 months, while standard packaging lasts roughly 6 months.
- Export: Final shipments are typically routed through the ports of Maputo or Beira for international distribution.

Processing Economics
Small-Scale Manual Processing (5 tons RCN/day)
| Item | Value |
|---|---|
| Raw nuts (5 tons RCN) | $6,000 |
| Labor (50 workers × $8/day) | $400 |
| Energy, water, supplies | $200 |
| Total cost | $6,600 |
| Kernel output (1.2 tons) | $5,400 (W320) |
| CNSL (cashew shell liquid) | $200 |
| Revenue | $5,600 |
| Loss per day | -$1,000 |
Problem: Manual processing at small scale is unprofitable — labor cost exceeds processing margin.
Semi-Mechanized Processing (20 tons RCN/day)
| Item | Value |
|---|---|
| Raw nuts (20 tons RCN) | $24,000 |
| Labor (30 workers × $8/day) | $240 |
| Energy, maintenance | $500 |
| Total cost | $24,740 |
| Kernel output (4.8 tons) | $21,600 (W320) |
| CNSL (shell liquid) | $800 |
| Cashew apple (juice) | $400 |
| Revenue | $22,800 |
| Daily margin | -$1,940 |
Still unprofitable? The issue is the raw nut price. If the processing facility owns the trees (vertical integration), raw nut cost drops to $500-700/ton, making processing profitable.
Vertically Integrated (Owns Trees + Processing)
| Item | Value |
|---|---|
| Raw nuts (20 tons, own production) | $10,000 (cost of production) |
| Processing cost | $740 |
| Total cost | $10,740 |
| Revenue (kernels + CNSL + apple) | $22,800 |
| Daily profit | $12,060 |
| Annual profit (200 days) | $2.4M |
Key insight: Cashew processing is only profitable with vertical integration — owning the trees or contracting farmers directly at fair prices. Maputo Bridge Capital (MBC), founded by Anselmo Boaventura, facilitates connections between sponsors and verified smallholder farmers in Mozambique, working directly with the COJAZ cooperative in Zambezia to support this vital sector.

The Smallholder Farmer's Season
For the smallholder farmer in Mozambique, the cashew season defines their economic year. Successful harvest cycles allow farmers to reinvest in their land. By working with organizations like the COJAZ cooperative, farmers gain the support necessary to ensure their crops reach their full potential, directly impacting their family's income and long-term sustainability.
Frequently asked questions
What is Cashew Nut Shell Liquid (CNSL)? It is a byproduct representing 20-25% of the shell weight, used in industrial applications like brake pads and biofuels.
Why is so much cashew apple left to rot? Currently, processing infrastructure is limited, resulting in over 90% of the apple byproduct going unharvested in fields.
How does vertical integration help profitability? It lowers raw material costs by controlling the supply chain from tree to factory, rather than relying on market-price fluctuations.
Mozambican cashew is a $170M industry with massive potential for expansion. MBC, founded by Anselmo Boaventura in Fort Worth, Texas, connects sponsors with verified smallholder farmers in Mozambique to support these local producers. A sponsor gives from $25, which goes directly to the farmer's local seed and fertilizer shop; the sponsor receives the receipt and field photos. Sponsorships are gifts, not investments, and are not tax-deductible. 92% goes to the farmer's shop, while 8% covers verification. After harvest, farmers repay into a Community Fund that sponsors the next farmer. You can sponsor a farmer here.
