Samyang Foods plans an estimated 218.6 billion won noodle plant in Thuan Thanh, Vietnam, adding a second planned overseas production site as it expands capacity to meet global demand.
The Korea Herald put the investment at about $150 million. The regulatory filing says the 218.6 billion won estimate may change and includes land, construction and equipment for one dried-noodle line. The facility is designed to house eight production lines. The filing says the estimate covers the initial line, with plans for additional lines to be set in stages.
The Korea Herald reported that Samyang plans to begin with one dried-noodle line and has set aside the other seven spaces for fried-noodle production. The newspaper said a company official cited lower costs for flour, palm oil and labor, along with access to European and Southeast Asian markets and quicker, less costly construction, as reasons for choosing Vietnam. It reported that Samyang expects to add further lines as demand grows.
A separate filing says 131.1 billion won of the investment will fund a wholly owned Vietnamese subsidiary tentatively named Samyang Foods Bac Ninh LLC. Samyang plans to make the contribution in installments through Jan. 31, 2029. At year-end 2025, the planned contribution represented 10.3% of Samyang’s consolidated equity.
Samyang identified its Jiaxing factory in China as its first overseas production site. Construction there began in September 2025 and is due to finish in December 2026, The Korea Herald reported. The newspaper said the factory is expected to produce more than 1.1 billion packs annually and raise Samyang’s total production capacity by about 43%.
Samyang says the Vietnam investment is intended to strengthen its ability to meet global demand and improve its overseas competitiveness. The filings set Jan. 31, 2029, as the Vietnamese plant’s target completion date.
