The chemical management regulation in Malaysia – “Environmentally Hazardous Substances Notification and Registration Scheme” (EHSNR) was proposed in January 2009. Data shall be submitted to Department of Environment based on voluntary principle. In 2011, the official regulation came into force and the submission of environmentally hazardous substances data are mandatory.
The purpose of the notification and registration scheme in Malaysia is to provide the necessary information to the Malaysian Government that will enable the Department of Environment and other agencies involved in chemicals management to identify substances of concern in the country and make decisions about how to manage the substances in a safe and sound manner.
Definition of EHS
An EHS is a substance that is included in the EHS Reference List or a substance with GHS classification according to Malaysia GHS.
The notification scheme covers:
- All substances not covered by other notification/registration schemes in Malaysia and fulfilling the criteria for classification as hazardous according to the Globally Harmonised System of Classification and Labelling (GHS), or until GHS is fully implemented, the classification according to the current classification requirements for chemicals in Malaysia.

substances formed during processing procedure
impurities or by-product
substances for export only

Two types of notification are used to manage environmentally hazardous substances: Basic Notification and Detailed Notification. Each type of notification applies to different substances.
1. Basic notification: for substances on EHS reference list.

Country of export (if imported).
- Shall be submitted each year.
2. Detailed notification: for substances not on EHS reference list.
- Required information:
- All documents required by basic notification;
- Molecular formula, molecular weight, molecular structure information;
- Physical and chemical properties;
- Physical and chemical category;
- Hazard information to human health;
- Hazard information to environment;
- GHS classification.
- Detailed notification will only be submitted once, unless Data of hazards are modified significantly.
