In April 2021, Malaysia’s Department of Environment (DOE) launched the Malaysia Environmentally Hazardous Substances (MyEHS) System. It has replaced the older Environmental Hazardous Substance Notification and Registration (EHSNR) system created since 2008 and become the primary platform for EHS management in Malaysia.
Background
The Environmental Quality Act 1974 established that there was a need to manage and control environmentally hazardous substances (EHS) in order to minimize effects to people and the environment. In order to be able to manage the potential adverse impacts of EHS imported into, produced and used in Malaysia the government needs information on the amounts of such substances that are used.
Objectives
The objective of the MyEHS System are:
to ensure importers and manufactures to notify the manufacturing and importation of EHS.
to provide the necessary information on EHS
to manage EHS in a safe and sound manner to protect the human health and the environment.
EHS Reference List
Environmentally Hazardous Substances (EHS) Reference List mainly include the following:
Chemicals listed in Annex III (Industry Chemical) of Rotterdam Convention
Chemicals listed in Annex A, B and C of Stockholm Convention
Chemical controlled in The Minamata Convention on Mercury
Chemical listed in Annex I & Annex V (Industrial Chemical) to the EU legislation (Regulation (EU) No 649/2012 (EU PIC Regulation)
Other substances that are considered substances of concern as determined by the Director General (e.g., chemical listed under Customs (Prohibition of Import) Order 2023 and Customs (Prohibition of Export) Order 2023.
Scope
MyEHS System covers all substances listed under EHS Reference List that will be import, export and/or manufacture in Malaysia.
However, MyEHS System does not apply to chemicals listed below:
Exemption mentioned under Article 3 of Rotterdam Convention
Exemption under Annex A, Annex B and Annex C of Stockholm Convention
Chemicals exported or imported for research or analysis if the quantities are unlikely to affect human health or the environment and do not exceed 10 kilograms per exporter to each importing country per calendar year under the EU legislation (Regulation (EU) No 649/2012 (EU PIC Regulation)
MyEHS System does not apply to substances for which information is already submitted to a government agency in Malaysia by means of other legislations. These regards substances notified/registered under the following legislations:
The Pesticides Act 1974 (Act 149)
The Poisons Act 1952 (Act 366)
Atomic Energy Licensing Act 1984 (Act 304)
Chemical Weapons Convention Act 2005 (Act 641).
Who shall comply
The importers, exporters and/or the manufacturers of EHS in Malaysia (Malaysia registered company) shall register, apply, and notify in the MyEHS System. This company need to have valid ROC company registration number before can proceed for MyEHS System registration.
Overseas suppliers must delegate the notification process through local importer/appointed agent.
It should be noted that MyEHS system is considered voluntary since DOE has not formulated any regulation legally binding to it.
Review Letter
Starting September 2023, all requests for DOE review letters regarding the import and export of hazardous chemicals (EHS) that fall under the Custom Order will need to be made through the MyEHS system. The period for processing review letters is 21 working days.
The application checklist is available here.
Please note that for all application under Customs Order, one (1) review letter will be issued for each chemical and shipment respectively (1 Review Letter / 1 chemical / 1 Shipment).
