Seoul – A humble, ubiquitous staple of Korean cuisine, dried seaweed, or "gim," is experiencing a dramatic price surge, driven by the relentless global appetite for Korean culture. What was once a readily accessible snack and cooking ingredient for South Koreans is now a sought-after commodity on the international stage, pushing its cost beyond the reach of many domestic consumers.
For nearly five decades, Lee Hyang-ran has presided over a small stall in a bustling central Seoul market, meticulously arranging stacks of dried seaweed. She vividly recalls a time when foreign palates found gim an unusual proposition. "In the past, people from Western countries thought Koreans were eating something weird that looks like a piece of black paper," she reminisced, her voice tinged with amusement and a hint of disbelief. "I never thought I'd be selling gim to them. But now, they all come here and buy it." This sentiment encapsulates the profound shift in perception and demand that has propelled gim onto the global culinary map.
The burgeoning popularity of K-dramas, K-pop, and Korean cinema has inadvertently created an insatiable demand for its accompanying culinary offerings, with gim emerging as a surprising frontrunner. Data from the Korea Maritime Institute (KMI) underscores this phenomenon, revealing a significant and sustained ascent in South Korea's dried seaweed exports. In 2025, the nation’s dried seaweed exports achieved a record-breaking milestone, reaching a colossal $1.13 billion. This surge signifies a dramatic departure from previous decades, where gim was primarily a domestic product with limited international recognition.
The impact of this escalating global demand is palpable in the domestic market. Consumers like Kim Jaela, a regular purchaser of gim who typically buys in substantial quantities – around 500 individual sheets at a time – have witnessed the inflationary pressure firsthand. In 2024, a single sheet of gim could be acquired for approximately 100 won (roughly $0.06), with multi-sheet packs costing in the vicinity of $0.60. However, just last month, the price of an individual sheet crept above the 150-won mark. This seemingly minor increase, when multiplied across bulk purchases, represents a considerable financial adjustment for devoted consumers. Furthermore, premium varieties of gim, once a niche offering, now command prices of up to 350 won per sheet, further exacerbating the affordability challenge.
This economic transformation is a direct consequence of gim's newfound international appeal, extending far beyond Asian markets to encompass North America and Europe. As consumers in these regions increasingly embrace Korean flavours, the pressure on South Korea's production capacity intensifies. The industry, once focused on meeting domestic needs, is now navigating the complexities of a global export market, where supply chain logistics and international demand dynamics play a crucial role in price determination.
The success of the K-wave, while a source of national pride and economic prosperity for the dried seaweed sector, presents a bittersweet reality for many South Koreans. The very product that has long been a simple, affordable culinary companion is now becoming a luxury item, a testament to the powerful, and sometimes unexpected, ripple effects of cultural influence on global commerce. The future trajectory of gim prices will undoubtedly be a closely watched indicator of the sustained power of Korean culture on the world stage.
