Objective To analyze the feasibility of using the decision tree in the process of integrating the relevant provisions and indicators of food additives in the Codex General Standard for Food Additives and the regional commodity standards, and propose solutions and suggestions for improving the working mechanism. Methods By attempting to integrate the additive provisions in the Codex General Standard for Food Additives and the four Asian regional commodity standards developed before 2012, the feasibility and limitations of the decision trees were discussed, and the key points and difficulties of the integration especially for regional commodity standards were analyzed. Results The decision tree is generally applicable, however some specific problems in the integration of regional commodity standards need to be resolved. Conclusion The decision tree could be used in the integration of the Codex General Standard for Food Additives and the regional commodity standards. In addition, it is necessary to sort out the correspondence between the foods categories. In accordance with the specific indicators, the revisement status of the provisions in the general standards, as well as the current technological justification, should be considered in the determination of the maximum levels of food additives.
