As an emerging market，China has witnessed rapid growth in organic food production and consumption in recent years. Several different organic labeling schemes from China，European countries，or American countries coexist in the market. In this study，differences in consumer preferences in organic milk powders with different certification logos were studied to provide a reference for participants in the organic food market. Based on the comprehensive analysis of the overall profile of the organic food market in China，research on 1，567 consumers in Shandong Province，China was performed through structured interviews. With organic milk powders as an example，choice experiments were conducted on four selected attributes，including logo，brand，origin，and price. A Random Parameter Logit model was established，under the assumption of consumer preference heterogeneity，to analyze the consumer preferences in organic milk powders with different attribute combinations. Model estimation results revealed that consumer preferences in organic milk powders varied greatly. Chinese consumers preferred milk powders labeled with official logos to powders labeled with private logos. In terms of countries，Chinese consumers preferred organic milk powders labeled with logos of North American countries，particularly milk powders originating from North America. In terms of social classes，highly educated classes preferred local brands，while the mass consumers preferred well-known brands and international brands. The consumer preference heterogeneity indicated that the arrangement of diversified labeling schemes satisfied the actual market demand in China. It is a practical way for Chinese certification organizations to conduct cooperation with foreign certification organizations，especially those in North America，for rapid development and better reputation.
