The distinct smell of red chilli powder fills the air at a kimchi factory in a city near Seoul. Inside, salted cabbage soaks in large metal vats during the primary stage of a traditional process.

"It's now considered a global dish originating in Korea, but this situation is absurd," says one producer. "This market has been taken away from us."

The difficulty originates from a widening import-export gap. South Korea brings in more kimchi than it exports, with lower-cost Chinese-made products gaining a foothold in the local market.

A Costly Difference

Chinese kimchi sells to restaurants at approximately 1,700 won per kilogram. Conversely, Korean-made versions are priced at about 3,600 won per kilogram—more than double the price.

In the first ten months of the year, the value of imports stood at $159 million, predominantly from China, while overseas sales were valued at $137 million.

A Cornerstone of Culture

This fermented dish is a cornerstone of food culture on the peninsula. The term covers far more than the spicy cabbage most familiar to global audiences.

• There are over 150 documented types, made with daikon, cucumbers, scallions and other vegetables.
• They are flavored with blends of chilli powder, garlic, ginger and jeotgal.
• The fermentation process produces health-promoting probiotics, contributing to its status as a nutritious food.

Shifting Habits

Traditionally, families made large quantities together during the annual kimjang ritual, a tradition designated by UNESCO. Yet, consumption patterns are changing.

One-person homes have more than tripled since 2000, now accounting for over 36% of all households. As a result, a declining number prepare it domestically.

Nowadays, it is more often eaten ready-made or in restaurants, where it is served free of charge with every meal. Asking payment for such a staple would be unthinkable.

A Difficult Business

"If you avoid losses and stay afloat, that’s considered lucky," says one manufacturer. "For many of us over the past decade, we could not afford to upgrade in facilities."

An Emotional Staple

Market forces mean that cost, rather than provenance or method, is now the decisive factor.

One factory owner who has run a facility for 29 years abandoned plans for expansion years ago as Chinese imports became popular. "Should we really be using kimchi from abroad when this is a food that embodies our heritage?" he says. "It's deeply saddening."

Additional Challenges

The pressures are compounded by the climate crisis, which is harming cabbage farming. Growing in summer has become increasingly difficult in traditional mountainous regions, causing wholesale cabbage prices to sharply increase from one year to the next.

Authorities and producers are working on climate-resistant varieties and improved storage systems, but industry groups question whether these steps can counteract the economic pressures.

Approximately three-quarters of the nation's kimchi manufacturers are very small enterprises with four or fewer employees, using labour-intensive methods that find it hard to compete with industrial-scale production in China.

Finding a Way Forward

The sector is attempting to adapt, albeit with limited tools.

• A voucher scheme offers restaurants a financial incentive to return to using domestically produced kimchi.
• There are calls for increased scrutiny of declared import prices for kimchi.
• Government initiatives include origin labeling programs for restaurants, agricultural support for cabbage growers, and research to extend kimchi’s shelf life for export.

The Final Defense

Ultimately, many are convinced that quality remains South Korea’s strongest defence.

"Korean kimchi has a unique taste," states an association head. "That cannot be replicated."
