Overview
Sanlu Group was a Chinese dairy manufacturer headquartered in Shijiazhuang, Hebei. Its corporate predecessor began operating as Shijiazhuang Dairy Company in 1956, and the Sanlu Group was formed in 1996 after a series of acquisitions. The business developed from a regional dairy producer into one of China’s largest milk-powder companies, with infant formula as its best-known and most commercially important product line. The company’s expansion was closely connected with Shijiazhuang’s municipal and collective-economy structure. Managers and employees held shares, while the city was the controlling shareholder. Under Tian Wenhua, who became the company’s leading executive after managing the predecessor dairy, Sanlu built a powerful position in the Chinese powdered-milk market. The company was reported to have ranked first in milk-powder sales for 15 consecutive years and to have employed nearly 10,000 people in Shijiazhuang. It also became one of the city’s largest taxpayers and an important purchaser from surrounding dairy farmers. Sanlu broadened its manufacturing footprint during the 2000s. It opened a powdered-milk plant in Tangshan, acquired a liquid-milk production base in Weifang, Shandong, and invested in a facility in Xinxiang, Henan, producing lactic-acid-bacteria drinks and yogurt. In 2007, reported group sales reached 10 billion yuan, while the milk-powder business was said to hold approximately 18 percent of the Chinese market. Public communications emphasized quality control, including claims that products underwent more than 1,000 tests before leaving the factory. In December 2005, Sanlu entered a joint venture with New Zealand dairy cooperative Fonterra. Fonterra invested 864 million yuan for a 43 percent stake, and the joint venture began trading in 2006. The partnership gave Sanlu additional international participation and capital during a period of rapid capacity expansion, but it did not prevent the company’s later governance and product-safety failure. The company’s reputation and existence were destroyed by the 2008 melamine contamination crisis. Infant formula carrying the Sanlu brand was adulterated with melamine, a non-food chemical used to falsely increase apparent protein readings. The contaminated products were linked to kidney stones and other illnesses in infants. Chinese authorities later reported that approximately 294,000 infants were affected nationwide and that six deaths were associated with the crisis. Sanlu had reportedly received complaints months before the public recall, and questions were raised about the timing of internal escalation, the response of local authorities, and the failure to withdraw products promptly. Sanlu apologized publicly in September 2008, halted production, and was ordered to destroy unsold and recalled goods. National testing found melamine in all 11 tested Sanlu samples, with the highest reported concentration reaching 2,563 parts per million. Fonterra wrote down most of the value of its investment and publicly separated itself from responsibility for the criminal adulteration, while the scandal spread across China’s dairy sector. The company could not recover commercially. Sanlu obtained financing for medical expenses and compensation, but creditor proceedings followed. The Shijiazhuang court accepted a bankruptcy petition in December 2008, and the company received a bankruptcy order on 24 December. Sanyuan subsequently announced plans to acquire several Sanlu facilities and assume part of its debt. Senior executives were prosecuted, with Tian Wenhua receiving a life sentence in January 2009. Sanlu therefore survives primarily as a case study in Chinese food-safety governance, corporate oversight, supply-chain control, and crisis management rather than as an operating consumer brand.
History
Sanlu’s origins date to 16 February 1956, when its predecessor, Shijiazhuang Dairy Company, began operating in the Hebei provincial capital. The business was embedded in the city’s collective ownership system, with managers and workers holding shares and the municipality serving as the controlling shareholder. Tian Wenhua, who had become general manager of the predecessor company, later led the transition to the Sanlu Group. Following several acquisitions in 1995, Sanlu Group was established in 1996. Under Tian’s leadership, it developed a strong national position in milk powder, especially infant formula. The company was described as the leading seller of powdered milk in China for 13 or 15 consecutive years, depending on the reporting period used, and became one of Shijiazhuang’s most important industrial employers and taxpayers. Its low-priced products were distributed widely and helped establish Sanlu as a familiar household name. The company expanded its production network during the 2000s. In February 2006, it opened a Tangshan facility with annual powdered-milk capacity of 200,000 tonnes. It acquired a liquid-milk base in Weifang, Shandong, in April 2006, and later invested in a Xinxiang, Henan, plant for yogurt and lactic-acid-bacteria beverages. These moves were part of a stated plan to invest 3 billion yuan in external growth and create a national industrial network. Sanlu also pursued foreign strategic investment. In December 2005, New Zealand cooperative Fonterra agreed to inject 864 million yuan in exchange for 43 percent of a joint venture. The venture began trading in 2006, while the majority stake remained with Shijiazhuang Three Deers Limited. In 2007, Sanlu reported sales of 10 billion yuan and held an estimated 18 percent share of the Chinese milk-powder market. Its marketing and public-relations profile stressed laboratory testing and quality assurance; a 2007 television program presented the company as carrying out more than 1,000 tests on products before release. The company’s trajectory changed completely after complaints about infant formula were reportedly received in late 2007. The products were adulterated with melamine, which can cause kidney stones and severe renal injury. The contamination became public in 2008, and testing by national authorities found failures in every tested Sanlu sample. The reported maximum concentration was 2,563 parts per million. The wider crisis affected hundreds of thousands of infants and resulted in six reported deaths associated with the contaminated products. Sanlu issued an apology on 15 September 2008, stopped production, and was directed to destroy recalled and unsold products. The episode generated intense criticism of the company’s internal controls, the handling of early complaints, the delay in initiating a full recall, and the conduct of local officials. Fonterra said it learned of the contamination after the issue had developed and informed New Zealand authorities in September; New Zealand officials then pressed Chinese authorities to act. The financial and legal consequences were rapid. Fonterra impaired most of its investment, while Sanlu sought funds to cover medical expenses and compensation. Sanyuan announced plans to acquire a number of Sanlu plants and assume part of its debt. The Shijiazhuang court accepted a creditor bankruptcy petition in December 2008 and issued a bankruptcy order on 24 December. Four senior Sanlu executives went on trial at the end of that month. In January 2009, Tian Wenhua was sentenced to life imprisonment, and other executives received lengthy prison terms. Sanlu subsequently ceased to exist as an operating dairy brand.
