Therefore, for the purpose of standardize bar code for commodity managementstandard, ensuring its quality, speeding up the application of it in electronic business andcirculating field and accelerating the course of being a well informed country, a new Bar Code ForCommodity Management Measures (New Measures for short) has been issued by the General Administratorof Quality Supervision, Inspection and Quarantine of P.R. China (AQSIQ) on May 30th, 2005, and putinto force in October, 2005. At the same time, the Old Measures issued on July 3rd, 1998 has beenabolished.展开更多
