Suruhanjaya Tenaga (ST) COA is Malaysia’s mandatory Certificate of Approval required to import, market, or sell regulated electrical equipment under the Electricity Supply Act 1990. Without an active ST COA and e-DIK company registration, Royal Malaysian Customs (JKDM) will block port clearance, triggering daily container demurrage at Port Klang or KLIA. Mindvox acts as your authorized local liaison to audit CB test reports, expedite ST approvals, and secure Dagang Net customs release in 24–72 hours.

Introduction
Ensuring the safety and reliability of electrical products is paramount in Malaysia. The Suruhanjaya Tenaga (ST), or Energy Commission, regulates the approval of electrical equipment to protect consumers and maintain industry standards. For manufacturers, importers, and retailers, understanding and obtaining the necessary approvals from ST is crucial for legal compliance and market access.
What is Suruhanjaya Tenaga (ST)?
Suruhanjaya Tenaga (ST) Approval is the compulsory electrical product safety certification mandated by the Energy Commission of Malaysia under the Electricity Supply Act 1990 and Electricity Regulations 1994. Importers and manufacturers of 34 categories of regulated electrical and electronic equipment must secure a Certificate of Approval (CoA) and apply the official SIRIM-ST safety label before goods can be legally sold or distributed in Malaysia.
Suruhanjaya Tenaga is the regulatory body responsible for overseeing the energy sector in Malaysia, including electricity and gas supply industries. One of its key roles is to ensure that all electrical equipment manufactured, imported, displayed, sold, or advertised in Malaysia meets specified safety and efficiency standards.
Certificate of Approval (CoA) Requirement
Under the Electricity Regulations 1994, certain categories of electrical equipment require a Certificate of Approval (CoA) from ST before they can be manufactured, imported, displayed, sold, or advertised. This regulation applies to:
Domestic Equipment: Appliances intended for household use.
Low Voltage Equipment: Devices usually sold directly to the general public that do not require special skills for operation.
The objective is to ensure that such equipment:
Is compatible with Malaysia’s electricity supply system.
Complies with established safety standards.
Has been tested by accredited laboratories.
Failure to obtain a CoA can result in legal penalties, including fines and confiscation of non-compliant products.
Application Process for CoA
To obtain a CoA, applicants must:
Register as a Manufacturer/Importer: Apply for a Certificate of Registration (CoR) through the e-DIK system (read our 2026 e-DIK customs clearance guide)
Submit CoA Application: Once registered, apply for the CoA via the e-Permit system
Provide Necessary Documentation: Include product specifications, test reports from accredited laboratories, and other required documents.
Await Evaluation: ST will assess the application and, if satisfactory, issue the CoA.
It’s important to note that the CoA is typically valid for one year, after which it must be renewed.
List of Regulated Electrical Equipment
ST maintains a list of electrical equipment categories that require a CoA, including but not limited to:
Plug Tops/Plugs: Devices that connect to socket outlets.Socket Outlets: Fixed or portable devices for electrical connections.
Switches and Dimmers: Devices for controlling electrical circuits.
Lamps and Lamp-Related Products: Luminaires and control gear.
Circuit Breakers: Safety devices to protect electrical circuits.
Household Appliances: Common domestic electrical devices.
Portable Power Tools: Handheld electrical tools.
Adapters/Chargers: Devices for charging or adapting electrical connections.
Wires/Cables/Cords: Electrical conductors and related products.
A comprehensive list and specific standards can be found in the Guidelines for the Approval of Electrical Equipment (Guidelines PDF).
Recent Updates
As of June 21, 2024, ST published the 7th edition of the Guidelines for the Approval of Electrical Equipment, which includes updated requirements and a one-year grace period for electric vehicle chargers.

Frequently Asked Questions (FAQ)
What is the difference between a Certificate of Registration (CoR) and Certificate of Approval (CoA)?
A Certificate of Registration (CoR) registers the business entity (importer or manufacturer) with Suruhanjaya Tenaga. A Certificate of Approval (CoA) is the product-specific safety approval granted for each regulated electrical model.
How long is an ST Certificate of Approval (CoA) valid?
An ST CoA is valid for 1 year and can be renewed annually, provided the underlying safety test reports and product specifications remain compliant.
What are the 34 regulated electrical categories under Suruhanjaya Tenaga?
Regulated items include plugs, socket-outlets, power adapters, electric irons, water heaters, refrigerators, washing machines, rice cookers, hair dryers, microwave ovens, televisions, LED luminaires, and vacuum cleaners.
Can international CB scheme or IEC test reports be used for ST CoA?
Yes. Valid IEC test reports and CB Certificates issued by accredited CB Testing Laboratories (CBTL) under the IECEE CB Scheme within the past 3-5 years are accepted by ST and SIRIM, avoiding local re-testing.
What is the penalty for selling non-ST approved electrical appliances in Malaysia?
Under Section 37 of the Electricity Supply Act 1990, selling unapproved electrical equipment carries penalties of up to RM 100,000 in fines, imprisonment of up to 5 years, or both, along with product confiscation.
