The Shanghai Nonferrous Metals Price Index (SMMI), a joint effort of Shanghai Xinxie Information & Technology Co., Ltd. and Zhejiang Gongshang University, was officially launched on May 28th 2007. The benchmark SMMI is based on the Shanghai market, China’s largest nonferrous metals market, with www.smm.cn as a platform, as well as strong support from Shanghai Nonferrous Metals Industry Association and hundreds of key enterprises of the country in this industry. A group of academic and professional experts has made high evaluation of SMMI, and SMMI is proved to be well-performed since its debut with scientific method and high application value. At present, SMMI has been published on www.cnni.net.cn and www.cif.mofcom.gov.cn simultaneously.
