Cashew Shell Price - Complete Market Guide & Current Pricing Trends 2025
The global market for cashew shell price continues to evolve as industrial demand for sustainable biomass and eco-friendly chemical feedstocks grows. Cashew shells, the robust outer covering of raw cashew nuts, have transformed from agricultural waste into valuable industrial commodities. Currently trading between $50 to $145 USD per metric ton globally, these shells serve dual purposes as biomass fuel and raw material for extracting Cashew Nut Shell Liquid (CNSL), making them increasingly important in the circular economy.
Current Cashew Shell Price Trends in 2025
Global Market Overview of Cashew Shells
The cashew nut shells market has experienced significant volatility over the past five years, with 2025 marking a period of elevated prices due to supply constraints. Current global pricing reflects a complex interplay of factors including reduced Raw Cashew Nut (RCN) harvests, increased industrial demand for biomass alternatives, and rising extraction costs for CNSL production.
In the current market, cashew shells are categorized into two primary grades:
- Raw cashew shellscontaining oil: $85-$145 per metric ton
- De-oiled shell cakeafter CNSL extraction: $50-$95 per metric ton
The price differential between these grades reflects the value of CNSL, which currently trades at $950-$1,200 per ton in international markets. Processing facilities increasingly recognize the economic advantage of extracting this valuable liquid before selling the remaining biomass for fuel applications.
Regional Price Variations for Cashew Nut Shells
India – The Largest Processing Hub
India dominates the cashew nut processing industry, creating substantial demand for shells as industrial fuel. Current pricing in major processing centers:
- Kollam, Kerala: ₹8,000-₹12,000 per metric ton ($95-$142 USD)
- Palasa, Andhra Pradesh: ₹7,500-₹11,500 per ton ($89-$136 USD)
- Mangalore, Karnataka: ₹7,000-₹11,000 per ton ($83-$130 USD)
These regional variations reflect local industrial demand, with areas hosting cement plants, brick kilns, and tile manufacturers typically commanding premium prices. The Indian market particularly values shells with consistent moisture content below 10% and oil content above 20% for optimal CNSL extraction.
Vietnam – Export-Oriented Pricing
Vietnam’s massive processing capacity generates substantial shell volumes, with pricing structured around export potential:
- Raw shells for domestic use: 1,200,000-2,000,000 VND per ton ($50-$83 USD)
- Export-grade shells: 2,000,000-2,500,000 VND per ton ($83-$100 USD)
- CNSL extraction grade: Premium pricing at 2,300,000-2,800,000 VND per ton ($96-$117 USD)
Vietnamese processors often integrate CNSL extraction facilities, adding value before export. The country’s strategic location facilitates shell exports to China, Japan, and South Korea, where demand for bio-based chemicals continues growing.
Historical Price Analysis: 2020-2025
Five-Year Market Evolution
The cashew shell price trajectory over the past five years reveals dramatic market shifts:
2020 – Pandemic Impact: Prices plummeted to $40-60 per ton as industrial activity declined globally. Reduced fuel consumption in manufacturing sectors eliminated much of the demand for biomass alternatives, creating oversupply conditions.
2021 – Recovery Phase: Gradual price recovery to $50-70 per ton accompanied industrial reopening. Manufacturing sectors resumed operations, rekindling demand for affordable fuel alternatives to coal.
2022 – Energy Crisis Peak: The Ukraine conflict triggered unprecedented energy price spikes, pushing shell prices to $80-130 per ton. Industries scrambled for coal alternatives, with biomass sources like cashew shells becoming highly sought after.
2023 – Market Stabilization: Prices moderated to $60-90 per ton as energy markets normalized. Adequate RCN supply maintained steady shell availability, preventing shortage-driven price increases.
2024 – Supply Concerns Emerge: Rising prices of $70-110 per ton reflected initial RCN harvest concerns. Climate irregularities in West Africa began affecting crop yields, signaling future supply constraints.
2025 – Current Supply Crisis: Present pricing of $85-145 per ton represents a 20-30% increase year-over-year. Severe weather impacts on African cashew harvests have reduced global RCN processing by approximately 20%, creating shell scarcity.
Factors Driving Cashew Shell Market Prices
Raw Material Supply Dynamics
The fundamental driver of cashew shells pricing remains RCN availability. As a processing byproduct, shell supply directly correlates with cashew processing volumes. The 2024-2025 harvest season has witnessed significant disruptions:
- West African production decline: Major producing countries including Ivory Coast, Ghana, and Nigeria report 15-25% yield reductions
- Vietnamese drought impact: Domestic RCN production fell 30%, increasing import dependency
- Indian crop variability: Uneven monsoons affected traditional growing regions
These supply constraints have created a seller’s market, with processors able to command premium prices for available shell inventory.
Industrial Demand Factors
Biomass Fuel Applications
The transition toward sustainable energy sources has positioned cashew nut shells as attractive biomass alternatives to fossil fuels. Key demand drivers include:
- Calorific value advantage: At 4,000+ kcal/kg, shells provide comparable energy output to low-grade coal
- Carbon neutrality: Biomass combustion offers reduced carbon footprint versus fossil fuels
- Government mandates: Stricter emissions regulations in India and Vietnam incentivize biomass adoption
Industries utilizing shell biomass include cement manufacturing, textile processing, food processing boilers, and power generation facilities. The consistency of shell supply from processing centers makes them preferred over seasonal agricultural residues.
CNSL Extraction Economics
Cashew Nut Shell Liquid represents approximately 20-25% of shell weight, containing valuable phenolic compounds. Current CNSL applications driving extraction demand:
- Friction materials: Brake linings and clutch facings require CNSL-based resins
- Surface coatings: Marine paints and industrial coatings utilize CNSL’s water-resistant properties
- Chemical intermediates: Growing demand for bio-based phenols in polymer production
With synthetic phenol prices linked to petroleum costs, CNSL becomes economically attractive when crude oil exceeds $80 per barrel, as currently observed.
Global Energy Market Correlation
The latest price movements in cashew shells closely track international energy markets:
- Coal price correlation: Shell prices typically maintain 15-20% of thermal coal prices
- Crude oil impact: CNSL demand increases when petroleum-derived phenol becomes expensive
- Natural gas influence: High gas prices drive industrial fuel switching to biomass
Current elevated energy prices across all sectors support strong shell valuations, with this trend expected to continue through 2025.

Frequently Asked Questions
Current cashew nut shells prices per kilogram vary by region and quality grade. In India, raw shells trade at ₹7-12 per kg ($0.083-0.142 USD), while de-oiled cake sells for ₹4.50-8 per kg. International markets see prices ranging from $0.05-0.145 per kg depending on oil content, moisture levels, and order volumes. Retail quantities command higher per-kg rates than bulk industrial purchases.
Cashew shells serve multiple industrial applications beyond basic fuel use. Primary applications include biomass fuel for boilers and furnaces, providing 4,000+ kcal/kg energy output. CNSL extraction yields valuable chemicals for friction materials, paints, and resins. Emerging uses encompass activated carbon production, agricultural char amendments, and composite material fillers. The shells' high lignin content makes them suitable for particleboard manufacturing, while research explores pharmaceutical and cosmetic applications for shell extracts.
Raw Cashew Nuts (RCN) with shells intact currently trade at ₹130-180 per kg in Indian markets. After processing, approximately 750-800 grams becomes shell and testa waste, while 200-250 grams yields valuable kernels. This processing ratio means each kilogram of RCN generates roughly 0.75-0.8 kg of shells, worth ₹5.25-9.60 at current market prices.
