With continued investment in processing, improved farming techniques, and expanded market access, Cambodia’s cashew industry is poised for long-term growth and global competitiveness.

Cashew Trees and Growing Conditions

The cashew tree (Anacardium occidentale L.) is a tropical evergreen that thrives in warm climates with well-drained soil. It belongs to the Anacardiaceae family, which also includes mangoes and pistachios​.

  • Climate Requirements: Cashew trees flourish in tropical regions with an annual rainfall of 400mm to 4,000mm and temperatures between 24°C and 28°C. Cambodia’s tropical climate provides ideal growing conditions, particularly in provinces such as Ratanakiri, Mondulkiri, Kampong Thom, and Preah Vihear​.
  • Soil Conditions: Cashew trees prefer sandy or lateritic soils with good drainage. They are drought-resistant and can grow in marginal lands where other crops struggle.
  • Growth & Lifespan: The trees can reach 8 to 12 meters in height and have a lifespan of 30 to 40 years, with peak production occurring between 8 and 15 years​.

 

Cambodia’s cashew trees are known for their high-yielding varieties, such as M23, which is weather-resistant and produces larger nuts​.

Different Parts of the Cashew Tree and Their Uses

The cashew tree produces multiple valuable products, making it an economically important crop.

1. Cashew Nut (Kernel) – The Edible Core

  • The cashew nut is the most valuable part of the tree, found inside a hard outer shell.
  • It is used in snacks, confectionery, and cooking (roasted, salted, or as an ingredient in sweets, sauces, and butters)​.
  • Cashew milk is becoming a popular lactose-free alternative in dairy-free markets​.

    • Juices and beverages (fresh or fermented into cashew wine)​.
    • Jams, syrups, and candies in local food industries.
    • Livestock feed and compost, reducing waste from cashew farming.

Cashew Shell – A Valuable Industrial Byproduct

  • The outer shell contains Cashew Nut Shell Liquid (CNSL), a thick, dark resin with industrial applications:
    • Used in varnishes, paints, brake linings, lubricants, and biofuels​.
    • Has antibacterial and antifungal properties, making it useful in pharmaceuticals.

Cashew Cultivation in Cambodia

Cambodia has become one of the world’s emerging cashew producers, thanks to its ideal climate, fertile soil, and expanding agricultural sector. The country has vast land suitable for cashew farming, and smallholder farmers play a crucial role in production.

Climate and Soil Conditions: Why Cambodia is Ideal for Cashew Cultivation

Climate

Cashew trees thrive in warm, tropical climates, making Cambodia an ideal location.

  • Average Temperature: 24–28°C year-round, with a dry season essential for harvesting​.
  • Annual Rainfall: 400–4,000mm, well within the range needed for cashew cultivation​.
  • Distinct Dry & Wet Seasons: The dry season (November to April) is perfect for harvesting, while the wet season (May to October) supports strong tree growth.

Soil Conditions

  • Well-Drained Sandy & Lateritic Soil: Cashew trees require light, well-aerated soil, which is abundant in Cambodia.
  • Drought-Resistant: Cashew trees can survive in poor soil conditions, making them a low-maintenance crop compared to rice and other staples.
  • Low Water Requirements: Unlike crops like rubber or sugarcane, cashews do not require irrigation, making them an attractive choice for farmers​.

Farming Practices: Traditional vs. Modern Methods

Cashew farming in Cambodia varies from traditional low-maintenance methods to modern techniques focused on quality and yield.

Traditional Farming Practices

  • Smallholder Dominance: 80–90% of Cambodia’s cashew production comes from small farms (less than 5 hectares)​.
  • Minimal Inputs: Farmers rely on natural rainfall, rarely using fertilizers or pesticides.
  • Manual Harvesting: Cashew nuts are handpicked after they fall to the ground.
  • Limited Processing: Most farmers sell raw nuts directly to traders for export to Vietnam, where they are processed and re-exported​.

Modern Farming Practices

  • High-Yield Varieties: Introduction of M23, H09, and other improved cashew strains that provide better nut size and yield​.
  • Organic Cultivation: Some farms are shifting to organic methods to meet global demand for chemical-free nuts​.
  • Agroforestry Practices: Farmers are integrating cashew trees with other crops (e.g., fruit trees) to enhance biodiversity and improve soil quality​.
  • Mechanized Processing: Growing investment in local processing facilities aims to keep more value-added processing within Cambodia​.

 

The shift toward modern, high-quality farming is helping Cambodia compete in international markets and reduce reliance on raw exports.

Common Challenges in Cashew Cultivation

Despite its growing success, Cambodian cashew farming faces several challenges that impact productivity and quality.

Pests and Diseases

  • Tea Mosquito Bug (Helopeltis antonii) – Damages young shoots and reduces nut yield.
  • Cashew Stem Borer (Plocaederus ferrugineus) – Infests tree trunks, leading to tree death.
  • Powdery Mildew – A fungal infection that reduces flowering and nut formation​.

Climate-Related Issues

  • Unpredictable Rainfall: Droughts can reduce cashew yield, while excessive rain can cause fungal infections.
  • Short Harvest Season: Cambodia’s cashew harvest occurs earlier than in Vietnam, leading to price fluctuations and dependence on a single buyer (Vietnam)​.

Limited Processing Infrastructure

  • 90% of raw cashew nuts are exported unprocessed to Vietnam, leading to lost value for Cambodian farmers​.
  • Few Large-Scale Factories: Cambodia lacks the processing capacity to produce large volumes of shelled, ready-to-eat cashews.
  • High Production Costs: Labor-intensive processing makes local factories less competitive​.

Market Access and Price Volatility

  • Farmers often lack direct market access and depend on traders who control pricing.
  • Vietnamese buyers dominate Cambodia’s cashew trade, leading to price fluctuations and low bargaining power for farmers​.

Organic Certification

  • EU Organic: Recognized across European countries.
  • USDA Organic: Required for U.S. exports.
  • JAS Organic: Mandatory for exports to Japan.
  • Certified by Control Union, Ecocert, or local organic certification bodies​.

Cashew Processing in Cambodia

Cashew processing is a key step in adding value to Cambodia’s cashew industry. While Cambodia produces over 1 million tons of raw cashew nuts (RCN) annually, more than 90% are exported raw to Vietnam for processing​. Increasing local processing capacity is essential for Cambodia to capture more value, create jobs, and gain direct access to international markets.

Processing Stages: From Raw Cashew Nuts (RCN) to Shelled Kernels

Drying and Cleaning

After harvesting, raw cashew nuts are sun-dried for 2–3 days to reduce moisture and prevent spoilage. They are then cleaned to remove dirt, debris, and foreign matter before further processing​.

Shelling (Manual vs. Machine Processing)

Shelling is one of the most labor-intensive stages due to the hard outer shell containing Cashew Nut Shell Liquid (CNSL), a caustic substance. In Cambodia, manual and semi-mechanical shelling are common, where workers crack shells using knives or hand-operated machines. While manual shelling is low-cost, it is slow and hazardous. Some factories use automated shelling machines, which improve efficiency and worker safety, but require high investment​.

Peeling, Grading, and Packaging

Once shelled, the kernels are dried again to loosen the inner skin before peeling, sorting by size and color, and grading (e.g., W-320, W-180, etc.). Processed cashews are then vacuum-packed or nitrogen-sealed to maintain freshness and prevent contamination​.

Processing Challenges: Breaking Dependency on Vietnam

Limited Infrastructure for Processing

Cambodia lacks large-scale processing facilities, forcing most farmers to sell raw cashews to Vietnam. Expanding local processing plants would allow Cambodia to capture more value​.

High Processing Costs & Market Barriers

Manual labor is expensive and slow, making it hard to compete with Vietnam’s automated factories. Additionally, exporting directly to premium markets (EU, U.S.) requires HACCP and organic certifications, which many small processors lack​.

The Future of Cashew Processing in Cambodia

Investments in processing plants, mechanization, and certification programs are helping Cambodia increase direct exports to global markets. Expanding automated processing and quality control will further enhance Cambodia’s competitiveness in the cashew industry​.

Logistics and Expor from Cambodia

Cambodia is emerging as a competitive supplier of cashew nuts, but exporting requires a well-managed supply chain, reliable transport logistics, and compliance with international trade regulations. This section outlines the journey of cashews from farmers to international buyers, key shipping methods and Incoterms, and the challenges exporters face.

Supply Chain Overview: From Farms to International Buyers

The Cambodian cashew supply chain involves several key players before the nuts reach international markets​.

  • Farmers → Harvest raw cashew nuts (RCN) and sell to middlemen or cooperatives.
  • Middlemen (Brokers/Traders) → Buy RCN from farmers and transport it to processors or export raw to Vietnam.
  • Processing Plants → Shell, dry, peel, grade, and pack cashew kernels (if processed in Cambodia).
  • Exporters → Handle quality inspections, certifications, documentation, and customs clearance.
  • International Buyers → Purchase cashews for further processing, retail, or food production.

Vietnam: The largest buyer of Cambodian raw cashew nuts (RCN). Over 90% of Cambodia’s cashew exports go to Vietnam, where they are processed and re-exported.

Direct Exports: Processed cashews are increasingly shipped to Europe, the U.S., Japan, and China, offering higher profit margins for Cambodian exporters.

Trade Agreements: Cambodia benefits from duty-free or low-tariff access to major markets under trade agreements like RCEP (Regional Comprehensive Economic Partnership) and the EU’s “Everything But Arms” (EBA) trade scheme.

Key Takeaway: The Cambodian cashew supply chain is still heavily reliant on Vietnam, but direct exports of processed cashews are growing, offering new opportunities for exporters.

  • Phnom Penh Port → Used for some container shipments.
  • Sihanoukville Port → Main deep-sea port for international exports.
  • Vietnamese Ports (Ho Chi Minh City, Vung Tau) → Often used for transshipment to final destinations​.
