Where the facts as finally established show that there is dumping and injury caused thereby, the EU Anti-dumping Law requires the Authority to examine Community interest before it decides to impose anti-dumping measures. The Community interest test means the Authority can impose anti-dumping measures only after it has evaluated the impact of anti-dumping duty on different competing interests, e.g., user industry and consumer. However, only few cases have been determined by the Commission not to impose anti-dumping measures on the ground of Community interest. Therefore, the Community interest test has been argued as disguised protectionism tool for Community industry. Thus, the article intends to explore these practical criteria of the Commission in assessing different competing interests in Community interest test as well as the possible amendment of Community interest regulation. To serve this purpose, this article will discusses the development of Community interest test and substantive and procedural requirements of Community interest test will be also analyzed. In addition, this article will examine recent anti-dumping cases to explore the rules and criteria of evaluating different competing interests in Community interest test by the Commission. The ways of different interest groups to defend their rights in the process of Community interest test will also be suggested. Possible direction of revising of current Community interest test will be further analyzed. This article finally concludes the discretion of the Commission in Community interest test is not unlimited but has criteria and rules. The Commission has been also approaching cost-benefit analysis on anti-dumping measures, particularly its negative impact on different competing interests in several cases recently. The Commission has to stand on fair basis to evaluate different competing interests in Community interest test as well as to create a good anti-dumping policy to assist European enterprises to cope with the dynamic economic environment. Amendment of Community interest regulation to including mandatory cost-benefit analysis and requiring a specified appropriate modality of anti-dumping measures to balance different competing interests is therefore in need for the EU.
