Speaking at the 15th Chemical Regulatory Annual Conference (CRAC) on November 17, 2023, Mr. Xu Wei from the Shanghai Emergency Management Bureau (SEMB) introduced Shanghai's localized pilot plan for the Hazchem traceability code system. The pilot plan aims to advance the implementation of the "One enterprise, One chemical product, One QR code" policy in Shanghai. Notably, Shanghai's pilot plan differs from the Hazchem QR code application piloted in Guangdong by requiring additional information, such as product batch numbers, for generating the Hazchem traceability code. This traceability code facilitates the tracking of Hazchem information and enables monitoring of Hazchem business operations throughout the whole supply chain. Highlights are summarized below.
