How to Apply for a CoA (Certificate of Approval) for Electrical Products? (Malaysia ST)

To sell regulated electrical products in Malaysia, the first thing you must complete is obtaining a CoA (Certificate of Approval) from the Energy Commission (Suruhanjaya Tenaga, ST). Without a CoA, the product may not clear customs and may not be legally listed. The whole path can be condensed into one sentence: confirm it is regulated → submit for SIRIM testing → apply to ST for the CoA → affix the ST certification label. For a full overview of the system, see the Malaysia electrical ST/SIRIM certification and labelling guide.

Why do you need a CoA?

Electrical products are directly linked to the risks of electric shock and fire, and Malaysia adopts a "pre-market gatekeeping" system: a regulated electrical product must first undergo third-party testing and then have an official approval certificate issued before it can enter the market. The CoA is that official certificate, proving that your model has passed the corresponding safety standard. Existing manufacturer marks such as CE or BSMI cannot replace the local CoA—Malaysia recognises the approval certificate it issues itself.

The CoA application process (step by step)

1. Confirm whether it is a regulated electrical product: regulated items are mostly those that directly contact mains power and carry a risk of electric shock or fire, such as plugs and sockets, cables, chargers and household appliances. If it is on the regulated list, you must obtain a CoA first; when unsure, confirm the latest list with ST or an accredited laboratory rather than guessing.
2. Submit samples for testing: send samples to a SIRIM or ST-accredited laboratory for type testing to the corresponding MS/IEC standard, obtaining a passing type test report. This stage is usually the most time-consuming, so be sure to schedule it early.
3. Apply to ST for the CoA: apply with the type test report, product specifications and factory data ready. The applicant (holder) must first complete local company registration (SSM).
4. Affix the ST certification label: after obtaining the CoA, the product can only go to market once the ST certification label bearing the approval number is affixed. For how to label, see the ST electrical safety labelling rules.

Understanding the timeline and validity

The CoA is a type approval: it is issued for a specific model, and a model change or expiry requires re-application or renewal—it is not approved once and valid for life. When the documents are complete, the administrative processing of a new application is relatively quick, but this does not include the earlier laboratory testing time—many sellers mistake the administrative days for the total time from zero to certificate, and their scheduling falls apart. The correct approach is to treat "testing + application" as the first stage to be completed before mass production or bulk importing.

Import vs. local manufacture: what's the difference?

Whether imported or locally manufactured, the CoA is required for both—this is the common baseline. The difference lies in the steps after the goods arrive:

In other words, the importer has two extra steps compared with the local manufacturer: "consignment inspection + country-of-origin marking." After the sea shipment arrives at port, the goods must first pass the consignment inspection, and only after passing can you obtain the label to affix; the overall lead time is usually longer, and the shipping schedule and customs inspection must be counted in together.

Common mistakes

• Importing and selling without a CoA—the most fundamental violation.
• Treating the administrative processing days as the total timeline, ignoring the earlier type-testing schedule.
• Reusing an old CoA for a revised model without re-applying.
• Forgetting the consignment inspection on imported arrivals, or omitting the country-of-origin marking.

Frequently asked questions (FAQ)

Q: Which electrical products need a CoA? Items on the regulated list announced by ST, mostly those that directly contact mains power and carry a risk of electric shock or fire (such as plugs and sockets, cables, chargers and household appliances). Products off the list must still meet general safety requirements. When unsure, confirm the latest list with ST or an accredited laboratory.

Q: Does the CoA have an expiry? Yes. The CoA is a type approval; a model change or expiry requires re-application or renewal, and it is not valid for life.

Q: Must it be sent to SIRIM for testing? A type test report must be issued by a SIRIM or ST-accredited laboratory, on the basis of which ST issues the CoA.

Q: Do both imports and local manufacture need a CoA? Both do. The difference is that imports must additionally undergo consignment inspection on arrival at port and add country-of-origin marking.

Self-check checklist

• [ ] Confirmed whether the product is a regulated electrical product (against the latest list)
• [ ] Sent to a SIRIM / ST-accredited laboratory for testing and obtained the type test report
• [ ] The holder has completed local company (SSM) registration
• [ ] Applied to ST and obtained the CoA
• [ ] Imported goods have undergone consignment inspection on arrival and added country-of-origin marking
• [ ] Affixed the ST certification label bearing the approval number

Summary

The CoA is the "entry ticket" for electrical products into Malaysia: first confirm it is regulated, then submit for SIRIM testing, apply to ST for the approval certificate, and finally affix the ST label bearing the approval number. Importers should not forget the consignment inspection on arrival and the country-of-origin marking, and should count the testing schedule into the total timeline early.
