Malaysia has implemented the Environmentally Hazardous Substances Notification and Registration Scheme (EHSNR) under the Environmental Quality Act since 2008. The EHSNR is designed to gather necessary information on chemicals for the government to establish sound management system.
Under the EHSNR Scheme, the Environmentally Hazardous Substance is defined as “a substance that is assigned a hazard category under the GHS classification scheme or is present on an existing internationally agreed list of prescribed substances”.
