Ex-Proof Smartphone Distributor in Muscat
Muscat is Oman's capital. The Mina Al Fahal area on its coast hosts an oil refinery and the base of Petroleum Development Oman, and Al Rusayl Industrial City lies outside the city. These are the main classified-area sites. Distribution partners for Muscat are being identified ahead of the Q4 2026 launch of the IS-04Z1.

Short answer. Muscat has no appointed SAMS distributor yet: the IS-04Z1 is pre-launch (certification in progress, no certificate issued, launch planned for Q4 2026), and distributor applications are open.
For the record, no certificate exists for the IS-04Z1 today. The programme is under way ahead of a Q4 2026 launch. An operator's own vendor approval is a separate step. Certification status. Place facts reviewed October 2026.

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 Muscat. For a refinery unit, crude and fuel storage or a factory using solvents or gases, a marking check reads zone, gas group and temperature class on the label and compares each with the operator's classification. Solvents and fuels span several gas groups, so the target marking II 2 G Ex ib IIC T4 is compared with site records.
The route · distribution
Distributing the IS-04Z1 in Muscat
Distribution of the IS-04Z1 is by authorised partners only, and SAMS has not yet granted a territory for Muscat. Each application is reviewed on its merits. Because opening a certified Ex handset in an ordinary workshop invalidates its certificate, the partner must be able to support and service the device locally.
What SAMS looks for in a partner
- Operator relationships
- Existing supplier registrations or a clear route to them with the main operators and contractors in Muscat.
- Ex-competent staff
- People who understand zone classification, markings and the conditions of a certificate.
And equally important
- Local-language support
- Documentation, training and helpdesk in the languages the workforce uses.
- Service capability
- Spares, battery replacement and repair routed through SAMS-approved channels.
Questions · Muscat
Frequently asked questions
Can we buy an Ex-proof smartphone in Muscat 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 smartphone in Muscat 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.
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 areas at Muscat would use it?
Likely candidates are refinery process units, crude export and fuel storage, industrial city factories using solvents or gases. Which areas are classified, and to what zone, is set by the site operator's own area classification drawings.
How do I become a SAMS distributor for Muscat?
Apply through the distributor page with your company details and the territory you cover. SAMS reviews applications company by company and has not yet granted a territory for Muscat.
Who is the main upstream oil operator?
Petroleum Development Oman, owned 60 percent by the government with Shell, TotalEnergies and Partex as shareholders. It has its own contractor registration and HSE approval.
Where are the classified areas in Muscat?
Mainly at Mina Al Fahal on the coast, at the refinery and oil company base, and at Al Rusayl Industrial City outside the city. The rest of the city is mostly commercial or residential.
Does Madayn set equipment rules for Al Rusayl?
Madayn manages Al Rusayl Industrial City, but each occupier classifies its own areas and sets its own rules. Ask the specific factory or operator what it requires for portable devices. Confirm details with the site operator.
