Certification labeling is a system which confirms the quality and appropriateness of pr oducts according to the standard set. It is usually evaluated by the third party to assure being reliability. Certification labeling can be used as one of the important sources of i nformation when consumers evaluate the products. Especially, certification labeling gi ves customers trust and confidence about products because the label can be the signali ng that the quality of the products is good. Although certification labeling influences p urchase decision making, many consumers do not trust the labels because of insufficie nt information of certification and distrust in the certifications. As consumers are becoming increasingly concerned about environment and wellbeing, manufacturers are turning a convention product into the production of a sustain able product. Sustainable certification can be environmental cues to evaluate a sustain able product based on the categorization inference. The aim of this research is the inte raction effect among sustainable cues on purchase intention. Consumers tend to perceive organic label of products as high-price. Thus, although they concern environment and well-being, they tend to purchase conventional products more than an organic product. In addition, an organic label can have a positive influence on perceived risk, and then perceived risk may affect purchase intention. However, the product with organic label including traceability may have a negative impact on perceived risk. Therefore, perceived risk can mediate the relationship between the interaction between organic label of products and traceability and purchase intention.
