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.

Ex-Proof Mobile Phone in Oman
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 mobile phone for Oman, and where the IS-04Z1 stands against that list today.

WhereOman
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.

Field notes · Oman
More about Oman that matters for portable equipment
Oman: logistics and access
The Port of Salalah, managed by APM Terminals, is a major transshipment hub, and the adjacent Salalah Free Zone is developing heavy industry.
Oman: background
The first economic oil find came in 1962 at Yibal, and the first oil consignment was exported in 1967.
Oman: infrastructure
Oman completed shutdown of its 3G networks in July 2025 and upgraded to 4G and 5G, which matters for choosing phone models and connectivity.
The term · Ex-proof
What “Ex-proof” means for a smartphone
“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.

Specifying an Ex-proof mobile phone for Oman
A short checklist for anyone writing or reviewing the specification, with the IS-04Z1 status against each point.
Check on the paper
- Marking
- Equipment group, category, protection concept, gas group and temperature class, matched to the area drawing.
- Certificate and schedule
- A certificate number, issuing body and the schedule of conditions, not a brochure claim.
- Standards edition
- The IEC 60079 or national standard edition the certificate was issued against.
Check for the IS-04Z1
- Marking target
- II 2 G Ex ib IIC T4: a target, not yet a certificate.
- Certificate status
- IECEx, ATEX, UKEX and NEC 500 in progress; none issued.
- Operator approval
- Separate from the certificate and handled with the site operator.
Questions · Oman
Frequently asked questions
Can we buy an Ex-proof mobile phone in Oman 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 Ex-proof mobile phone in Oman 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.
What Ex marking will the IS-04Z1 carry?
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.
Which sites in Oman does this cover?
The market guide for Oman covers Fahud, Yibal, Marmul, Qarn Alam, among others. Site-level pages are linked below.
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.
Which areas have heavy industry?
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.
Who runs Oman's upstream oil and gas?
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.
Can the IS-04Z1 work with sour gas detection in the south?
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.
