Administration
The Royal Commission for Jubail and Yanbu runs the industrial city; each plant operator sets its own contractor rules.

IECEx Mobile Phone in Jubail
The Royal Commission's chairman's office is in Riyadh, with separate directorates general in Jubail and Yanbu, so city-level services are run locally while plants set their own rules. It houses SABIC plants, the SATORP and SASREF refineries and the Sadara chemical complex, so classified areas are widespread. This page explains what to look for in an IECEx mobile phone for Jubail Industrial City, and where the IS-04Z1 stands against that list today.

The term · IECEx
What “IECEx” means for a smartphone
IECEx is the international scheme for certifying equipment used in explosive atmospheres. A certificate of conformity is issued by an accredited certification body against a specific edition of the IEC 60079 standards and carries a schedule of conditions of safe use. It is not a legal requirement in most countries on its own, but many national schemes accept it as the technical basis.
The IECEx certificate for the IS-04Z1 is in progress and has not been issued. The marking target is Ex ib IIC T4, the intrinsic safety concept for Zone 1 gas with the hardest gas group (IIC) and a 135 °C temperature class.
In Jubail Industrial City. With operators such as SABIC, SATORP, Sadara, Kemya and SASREF in one industrial city, international contractors and EPCs frequently move between plants. IECEx provides a shared reference, with a certificate of conformity and schedule of conditions to read. For the IS-04Z1 these are targets only, as certification is in progress.

Questions · Jubail
Frequently asked questions
Can we buy an IECEx mobile phone in Jubail today?
No. Nothing can be bought or taken into a classified area today: certification is in progress and launch is planned for Q4 2026. What is available now is the datasheet, the written certification schedule and evaluation units for safe-area use.
What does an IECEx mobile phone in Jubail cost?
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.
Does the IS-04Z1 hold an IECEx certificate?
No. The IECEx certificate is in progress and has not been issued. SAMS will publish the number when it exists.
Which areas at Jubail Industrial City would use it?
Likely candidates are refinery process units, petrochemical and chemical plants, storage and loading terminals, port bulk handling. Which areas are classified, and to what zone, is set by the site operator's own area classification drawings.
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.
Is Jubail one operator or many?
Many. The Royal Commission plans and runs the industrial city, but chemical, refining, power and port companies operate their own plants under their own safety and permit rules. Equipment approval for handheld devices is usually decided plant by plant.
Does Jubail's utility infrastructure create classified areas?
Gas-fired power and desalination plants usually include fuel-gas supply areas, so some classified zones are likely. The city's independent water and power project is among the largest in the world, so contractor numbers are high; confirm requirements with the specific plant.
Do approvals carry across plants in Jubail?
Not automatically. Each plant operator sets its own approved-vendor and permit rules, so approval at one plant does not guarantee acceptance at another. Confirm current requirements with the operator or its contractor for each plant. This applies on top of explosion-protection certification.
