Sempio Foods operates on two pillars: traditional fermented sauces (soy sauce, soybean paste, red pepper paste, and ssamjang) and non-sauce processed foods such as the liquid seasoning Yondu, pasta sauce Fontana, Asian sauce Tiasia, and jerky brand Jilleo.
Recent reports indicate the sales mix between sauce and non-sauce products has diversified to roughly a 50:50 split, though total revenue remains heavily concentrated domestically, with overseas sales reported at around 16%.
In its core soy sauce business, Sempio held a dominant 59.18% retail market share in 2024, far ahead of Daesang (22.94%) and Mongo Foods (7.02%). Across the broader fermented sauce brand market, Sempio also leads with a 53.36% share, with CJ CheilJedang competing for the number-two position.
Distribution is being reshaped as offline channels such as hypermarkets shrink, a shift that has also affected the performance of its promotional affiliate, Sempio ISP.
In 2026, marking its 80th anniversary, the company launched 'Brewed Soy Sauce 801,' its first new premium soy sauce line since '501' (1989) and '701' (1994), expanding its premium lineup.
Rival CJ CheilJedang also relaunched its 'Haechandle Yetjang' soy sauce after a 13-year hiatus, intensifying premiumization competition across the sauce category.
This combination of overwhelming dominance in its core category and ongoing diversification into non-sauce and overseas businesses defines Sempio Foods' business structure.
