Oman: rules and approvals
In February 2026 the TRA launched a Self-Declaration of Conformity service for importers, so the approval route for some products is changing.
The IS-04Z1 is an intrinsically safe smartphone designed for Zone 1 and Zone 21, aimed at the field operators, technicians, inspection engineers and HSE teams who work inside Oman’s classified areas. This page explains what to look for in an Ex-proof cell phone for Oman, and where the IS-04Z1 stands against that list today.
Pre-launch · certification in progress · Launching Q4 2026
Short answer. The SAMS IS-04Z1 is the intrinsically safe smartphone covered here for Oman: pre-launch, designed for Zone 1 and Zone 21 (marking target Ex ib IIC T4), with certification in progress and no certificate issued.
Where things stand: the IS-04Z1 has not launched, and none of its four certification routes has produced a certificate yet. An operator's own vendor approval is a separate step. Certification status. Place facts reviewed October 2026.
| Check | What to look for | IS-04Z1 today |
|---|---|---|
| Ex marking | Group, category, protection concept, gas group, temperature class | II 2 G Ex ib IIC T4 (target) |
| Gas group | IIA, IIB or IIC matched to the area drawing | IIC (target) |
| Temperature class | T-class below the ignition temperature of the gas | T4, 135 °C (target) |
| Where it applies | Oman: Fahud, Yibal, Marmul | Classified by the site operator |

An intrinsically safe Android smartphone designed for Zone 1 and Zone 21 hazardous areas in Oman. It is pre-launch: IECEx, ATEX and NEC 500 certification is in progress ahead of the Q4 2026 launch.
The classified areas, operators and sites below are the ones covered in the SAMS Oman market guide.

The Port of Salalah, managed by APM Terminals, is a major transshipment hub, and the adjacent Salalah Free Zone is developing heavy industry.
The first economic oil find came in 1962 at Yibal, and the first oil consignment was exported in 1967.
Oman completed shutdown of its 3G networks in July 2025 and upgraded to 4G and 5G, which matters for choosing phone models and connectivity.
“Ex-proof” is shorthand for equipment carrying an explosion-protection marking (the Ex mark) that matches the area it enters. The marking states the protection concept, gas or dust group and temperature class, and it must be backed by a certificate issued by a recognised body, so a phone described as Ex-proof should come with a certificate number you can check.
The IS-04Z1 is designed to carry the marking II 2 G Ex ib IIC T4. That is a target: certification is in progress, no certificate has been issued, and SAMS will publish the certificate numbers when they exist.
In Oman. A marking check in Oman starts with II 2 G Ex ib IIC T4 against the operator's classification. Summer in the interior sits well above 45 degrees, so the temperature class on the certificate is the figure a technical safety engineer checks. Dust and sand add Zone 21 questions at thermal plants and industrial estates.
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.
No price is published. While certification is in progress there is no list price and no committed lead time, and a supplier quoting a firm figure for an uncertified Ex handset is promising something it cannot stand behind. Indicative pre-launch pricing is issued in writing against a stated quantity and site.
The marking target is II 2 G Ex ib IIC T4. It becomes a marking only when the certificate is issued; until then it is a design target.

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.
Muscat's Mina Al Fahal and Rusayl, Salalah's free zone, and the Duqm special economic zone, along with fields in the interior. Each is managed by a different authority.
Petroleum Development Oman handles most crude and gas, with the government holding 60 percent and Shell and others sharing the rest. Other operators run separate blocks. PDO has its own contractor approval system.
It is designed to pair with a personal gas detector over Bluetooth so the two work together. Sour gas developments such as Harweel already require detection as routine, so confirm the pairing and alarm procedure with the operator's HSE team before adding the handset.
