Walnuts, known for their crunchy texture and rich, earthy flavor, are one of the oldest cultivated tree nuts in human history. Highly valued for both their culinary versatility and impressive health benefits, walnuts are popular in kitchens, bakeries, and health food stores across the globe. But when it comes to exporting these prized nuts, one country consistently leads the world.
So, which country is the largest walnut exporter in the world? The answer is clear: The United States holds this title by a wide margin. In this article, we’ll explore the global walnut trade, what makes the U.S. the leading exporter, other key players in the market, and the trends shaping international demand.
Global Walnut Market Overview
Walnuts are cultivated in temperate regions worldwide, especially in the Northern Hemisphere. Major producers include the United States, China, Chile, Ukraine, Iran, and several countries in Europe and Central Asia.
There are two primary categories of walnuts in global trade:
- In-shell Walnuts: Walnuts sold with their hard shells intact.
- Shelled Walnuts: The edible kernel removed from its shell, ready for direct consumption or industrial use.
The international walnut market is sizable, driven by rising consumer demand for plant-based proteins, healthy fats, and versatile cooking ingredients.
The United States: World’s Leading Walnut Exporter
The United States, and particularly California, is the dominant force in global walnut exports. According to the United States Department of Agriculture (USDA) and International Nut and Dried Fruit Council (INC):
- The U.S. accounts for nearly 50–55% of total global walnut exports by value.
- In 2023, U.S. walnut exports reached an estimated $1.4 billion.
- California produces virtually 99% of U.S. walnuts and about one-third of global supply.
Major Walnut Export Markets for the U.S.
The U.S. exports walnuts to over 50 countries, with key destinations including:
- European Union (Germany, Spain, Italy)
- Turkey
- United Arab Emirates
- Japan
- South Korea
- India
The European Union remains the largest importer of both U.S. in-shell and shelled walnuts, particularly for use in confectionery, baking, and health snack sectors.
Why the U.S. Leads in Walnut Exports
Several factors contribute to America’s leadership in the walnut export market:
- Ideal Climate: California’s Mediterranean climate — with cool winters and hot, dry summers — is perfect for walnut cultivation.
- Advanced Farming Practices: Mechanized harvesting, efficient irrigation, and research-backed cultivation methods yield consistently high-quality walnuts.
- World-Class Processing Infrastructure: California walnut processors use modern shelling, grading, and packaging facilities, ensuring premium standards.
- Global Market Access: Decades of trade relationships and strategic market promotion by the California Walnut Commission have opened export doors worldwide.
Other Major Walnut Exporting Countries
While the U.S. leads the market, other nations play crucial roles in global walnut trade:
China: Largest Producer, Rising Exporter
- China is the world’s largest walnut producer, accounting for over 50% of global production.
- Though historically a domestic consumption market, China has steadily increased its exports, especially to South Korea, Vietnam, and Middle Eastern countries.
- Chinese walnuts are valued for their lower cost, though quality consistency varies compared to U.S. produce.
Chile: Southern Hemisphere Supplier
- Chile is the third-largest walnut exporter globally, with exports valued at approximately $400–450 million in 2023.
- Chile’s Mediterranean-like climate allows for counter-seasonal walnut harvests (March-May), providing fresh walnuts when Northern Hemisphere stocks wane.
- Major markets include Europe, India, and the Middle East.
Ukraine: Fast-Growing Walnut Exporter
- Ukraine has rapidly emerged as a major walnut exporter, shipping both in-shell and shelled nuts to EU countries and the Middle East.
- Ukraine benefits from vast arable land and a favorable climate, though recent geopolitical tensions have affected agricultural exports.
Iran: Traditional Supplier
- Iran remains a significant walnut producer and exporter, particularly within the Middle East and Central Asia.
- Trade restrictions and sanctions have limited Iran’s ability to access broader international markets.
Trends in the Global Walnut Export Market
The international walnut trade has seen dynamic changes in recent years, driven by health trends, culinary innovation, and shifting global diets. Key trends include:
Rising Health-Conscious Consumption
Consumers worldwide are embracing walnuts for their health benefits. Rich in omega-3 fatty acids, antioxidants, plant protein, and dietary fiber, walnuts are linked to:
- Heart health
- Brain function support
- Anti-inflammatory properties
This has boosted demand in both raw and value-added formats like walnut oils, snack mixes, and bakery ingredients.
Growth in Plant-Based & Functional Foods
Walnuts are increasingly used in plant-based meat alternatives, dairy-free cheeses, and health food products. This trend is strong in North America, Europe, and East Asia.
Expanding Asian Markets
Countries like India, Japan, South Korea, and Vietnam are experiencing surging demand for walnuts, driven by urbanization and a growing middle class seeking nutritious snacks.
Emphasis on Sustainability
Sustainable farming practices, water-efficient irrigation, and eco-friendly packaging are becoming vital to meet both regulatory standards and consumer expectations in premium markets like the EU.
Market Diversification
U.S. exporters are increasingly targeting emerging markets in Southeast Asia, the Middle East, and Latin America to reduce dependency on traditional buyers.
Challenges Facing Walnut Exporters
Despite positive market trends, walnut exporters encounter several hurdles:
- Climate Challenges: Droughts and changing weather patterns, especially in California, impact yields and quality.
- Trade Tariffs: U.S. exports faced retaliatory tariffs from countries like China during recent trade tensions, temporarily affecting market share.
- Global Logistics Issues: Shipping delays, container shortages, and increased freight costs have posed operational challenges since 2021.
- Geopolitical Risks: The Russia-Ukraine conflict disrupted exports from Eastern Europe and altered trade flows.
