More Chinese Cities to Pilot Hazchem QR Code, Including Suzhou

A quick response (QR) code is a type of barcode that stores information and can be read easily by a digital device; thus, it’s frequently used to track product information in the supply chain. To facilitate the information management of hazardous chemicals, China introduced the “One enterprise, one chemical product, and one QR code” principle in early 2022 as per the National Plan for Centralized Management of Safety Risks of Hazardous Chemicals¹. Following this principle, China launched the new Hazardous Chemical Registration Comprehensive Service System on February 16, 2022 to support the automatic generation of QR codes for registered hazardous chemicals (CL news²).
