Saudi Arabia: background
The Royal Commission for Jubail and Yanbu was established in 1975 to develop two coastal industrial centres, Jubail on the Arabian Gulf and Yanbu on the Red Sea.
The IS-04Z1 is a Zone 1 and Zone 21 handset for people who work inside classified areas in the Kingdom: field operators, maintenance and inspection engineers, and the HSE and telecoms teams who equip them. If you are specifying an explosion proof cell phone for Saudi Arabia, this page covers the markings, the approvals and the current certification status of the IS-04Z1.
Pre-launch · certification in progress · Launching Q4 2026
Short answer. The SAMS IS-04Z1 is the intrinsically safe smartphone covered here for Saudi Arabia: pre-launch, designed for Zone 1 and Zone 21 (marking target Ex ib IIC T4), with certification in progress and no certificate issued.
Status: pre-launch. IECEx, ATEX, UKEX and NEC 500 certification is in progress and no certificate has been issued; launch is planned for Q4 2026. Operator approval runs on its own timeline. Certification status. Place facts reviewed October 2026.

An intrinsically safe Android smartphone designed for Zone 1 and Zone 21 hazardous areas in Saudi Arabia. It is pre-launch: IECEx, ATEX and NEC 500 certification is in progress ahead of the Q4 2026 launch.
Operators and classified areas drawn from the SAMS Saudi Arabia market guide.
The Royal Commission for Jubail and Yanbu was established in 1975 to develop two coastal industrial centres, Jubail on the Arabian Gulf and Yanbu on the Red Sea.
Ras Tanura Port is described as the world's largest crude oil export terminal, handling about 20 percent of global oil exports and over 2,000 tankers a year.
Ras Tanura Refinery was established in 1939 and is the largest refinery in Saudi Arabia, run by Saudi Aramco.
Jubail has the world's largest independent water and power project, producing about 2,744 megawatts of electricity and 800,000 cubic metres of water daily.
“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 Saudi Arabia. The everyday phrase explosion-proof covers several concepts at Abqaiq, Ras Tanura and Ghawar. Flameproof Ex d suits heavy fixed equipment, whereas the IS-04Z1 relies on intrinsic safety, limiting the energy available in the handset. For a reviewer the question is which concept applies to the device being carried into the area.
A short checklist for anyone writing or reviewing the specification, with the IS-04Z1 status against each point.
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.
There is no list price yet. SAMS gives indicative pre-launch pricing in writing, against a stated quantity and site, and does not commit to a lead time before certification completes.
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.
The market guide for Saudi Arabia covers Abqaiq, Ras Tanura, Ghawar, Shaybah, among others. Site-level pages are linked below.
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.
Saudi Aramco, SABIC and other large operators set their own supplier and equipment standards within national regulation, and the Royal Commission manages Jubail and Yanbu. Ask the end user for its approved-vendor requirements before shipping any device.
Jubail and Ras Tanura on the Gulf coast, Yanbu on the Red Sea, and many Saudi Aramco fields and plants inland. Jubail and Yanbu are managed by the Royal Commission.
The 4,000 mAh battery is specified for a full shift, because recharging inside a classified area is not possible and stores can be far away. Actual runtime depends on camera, torch and GNSS use, so test it on a real round during an evaluation.
