01Question one: does it transmit?
Wi-Fi, Bluetooth, cellular, radio, NFC, a remote control — anything with a communications function. If yes, MCMC applies and SIRIM QAS certifies it.
This is broader than most people expect. It covers the obvious things — phones, tablets, routers, network equipment, wireless keyboards. It also covers products whose main purpose has nothing to do with communications but which contain a module: smart TVs, wireless chargers, games consoles, connected appliances. Malaysia treats these as hybrid products, and there is a separate list of tariff codes covering them beyond the core communications headings.
02Question two: is it mains-powered?
If yes, and it is consumer equipment on the Energy Commission’s regulated list, that is a second regime — with SIRIM QAS doing the consignment testing.
Equipment operating under 50V AC or 150V DC is outside the Energy Commission’s scope. Battery-powered, USB-powered and vehicle-DC-powered products do not need a Certificate of Approval from them.
The Energy Commission’s list runs to 34 categories and includes: plugs and sockets, switches and dimmers, circuit breakers, lamp fittings and lighting control gear, kettles, kitchen machines, toasters and ovens, rice cookers, refrigerators, water heaters, washing machines, fans, hair and skincare appliances, irons, shavers, vacuum cleaners, hi-fi and audio-video equipment, visual display units, massagers, air conditioners, Christmas lights, portable power tools, adapters and chargers, and wire, cable and cord.
Example: A battery-powered Bluetooth speaker: MCMC only. The same speaker mains-powered: MCMC and the Energy Commission.
Do not assume: A class assignment does not exempt you. MCMC states explicitly that devices issued with a class assignment are still required to be certified by the Commission or its registered certifying agency.
If you are not sure whether your product is in scope, that is the normal position and it is the first thing we check.
