Supplier approval · Petronas
Supplier registration at Petronas
Suppliers apply for a PETRONAS licence or registration through the PETRONAS Licensing Management System (PLMS), then trade through its procurement platforms such as the Unified Procurement Platform and B2B Marketplace. A licence covers upstream and downstream supply; a registration covers downstream subsidiaries only. The Ex certificate and an organisation's own vendor or engineering approval are two separate timelines; SAMS is working towards both and holds neither today.
Field notes · Petronas
More about Petronas that matters for portable equipment
Petronas: background
Petronas was established and incorporated on 17 August 1974 under the Petroleum Development Act, and is vested with all oil and gas resources in Malaysia, so it is the licensor as well as an operator.
Petronas: projects and investment
In 1978 Petronas set up the Malaysia LNG joint venture with Mitsubishi and Shell, taking 65% equity, which led to the large LNG complex in Bintulu, Sarawak, with its cryogenic and gas hazards.
Petronas: industry on the ground
The company is vertically integrated, active in exploration, extraction, refining, distribution and marketing, power generation and trading, so hazardous areas span offshore platforms, plants and fuel retail.
The term · explosion proof
What “explosion proof” means for a smartphone
“Explosion proof” is the phrase most buyers use for equipment that may be taken into a classified hazardous area. Strictly, it covers several protection concepts: a flameproof enclosure (Ex d) contains an internal explosion, while intrinsic safety (Ex i) limits electrical energy so that an ignition cannot start. Phones are normally intrinsically safe, because a flameproof handset would be too heavy to carry all shift.
The IS-04Z1 uses intrinsic safety, with a marking target of Ex ib IIC T4, and is designed for Zone 1 and Zone 21. It is pre-launch, certification is in progress and no certificate has been issued.
In Petronas. At Bintulu LNG, Kertih or Pengerang, explosion-proof is everyday shorthand for different concepts. Flameproof Ex d protects fixed equipment such as motors and junction boxes, while intrinsic safety limits electrical energy and suits phones. LNG liquefaction brings flammable natural gas, so a portable device is judged on intrinsic safety, which the IS-04Z1 is designed around.

Questions · Petronas
Frequently asked questions
Can Petronas buy the IS-04Z1 today?
Not yet. The IS-04Z1 is pre-launch and its certification is still in progress ahead of a Q4 2026 launch. No unit goes into a classified area before the certificate covering it exists. The datasheet, the certification schedule and safe-area evaluation units are available now.
What does an explosion proof mobile phone for Petronas cost?
SAMS has not published a price. Any figure you are offered for an uncertified Ex phone should be treated with caution; written indicative pricing is available for a defined quantity and site.
Is the IS-04Z1 explosion proof or intrinsically safe?
It is intrinsically safe (marking target Ex ib IIC T4), which is the usual way to make a phone for hazardous areas. It is not a flameproof (Ex d) design, and certification is still in progress.
How does Petronas approve suppliers?
Suppliers apply for a PETRONAS licence or registration through the PETRONAS Licensing Management System (PLMS), then trade through its procurement platforms such as the Unified Procurement Platform and B2B Marketplace. A licence covers upstream and downstream supply; a registration covers downstream subsidiaries only.
Is intrinsically safe the same as explosion proof?
Not exactly. Explosion proof is a broad everyday term; intrinsic safety is one protection concept, which limits energy so ignition cannot occur. Flameproof (Ex d) is a different concept that contains an explosion. The IS-04Z1 is intrinsically safe by design.
How do suppliers register with Petronas?
Petronas runs a vendor registration and licensing process for suppliers and contractors, and its business units apply their own technical assessment. Details change, so confirm the current registration route and product categories directly with Petronas procurement before offering equipment.
Which Petronas sites typically need intrinsically safe phones?
Typical Zone 1 and Zone 2 sites include offshore platforms, gas processing and LNG facilities such as Bintulu, refineries, petrochemical plants and fuel terminals. Classification is site-specific, so ask the operating unit's HSE team for area classification drawings and its rules for portable electronics.
Does a supplier need a PETRONAS licence to sell a handheld device?
PETRONAS says suppliers apply for a licence or registration through its licensing system. A licence covers upstream and downstream supply, while a registration covers downstream subsidiaries only. Check current requirements with PETRONAS. SAMS has appointed no distributor, and the IS-04Z1 has no certificate yet.
