Foshan Haitian Flavouring and Food Company Ltd., tracing its origins to the historic Foshan Sauce Garden established during the Qing Dynasty in the 18th century, is China's largest and most iconic soy sauce and condiment manufacturer. Headquartered in Foshan, Guangdong province, the modern enterprise was formally incorporated in 1995 and has since grown to dominate the Chinese condiment market with an extensive product range including soy sauce, oyster sauce, vinegar, cooking wine, bean paste, and compound seasonings. Haitian's products reach hundreds of millions of Chinese households and food service establishments through a distribution network of over 5,000 distributors, making it one of the most widely consumed food brands in China. The company has been listed on the Shanghai Stock Exchange since 2014.

Haitian's competitive moat is its unparalleled manufacturing scale in traditional fermentation-based condiments, where its massive solar-dried fermentation tanks covering over 800,000 square meters create natural barriers to entry that smaller competitors cannot economically replicate. The company's brand heritage and distribution depth provide pricing power and shelf-space dominance across both modern trade and traditional retail channels, while its continuous process innovation in natural brewing technology ensures consistent product quality at industrial scale. In 2025, Haitian published its ESG report detailing its water stewardship program, which has achieved significant reductions in water consumption per ton of product through closed-loop cooling systems and wastewater recycling. The company has also invested in renewable energy integration at its Foshan headquarters, including biogas capture from fermentation byproducts for on-site power generation.
