Twenty-three of the 24 ministries and firms such as SABIC and STC are headquartered here, so many buyers and contractors are based in Riyadh even when classified areas are elsewhere.

Ex-Proof Smartphone Distributor in Riyadh
Riyadh is Saudi Arabia's capital and its administrative and commercial centre, with almost one-third of the country's factories. Aramco's Riyadh Refinery and manufacturing plants create Zone 1 and Zone 21 areas, but most hydrocarbon sites are in the Eastern Province. An Ex-proof smartphone distributor in Riyadh would carry the IS-04Z1 to these buyers once certification completes.

Short answer. Riyadh 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. A buyer's engineering review is separate from the certificate. Certification status. Place facts reviewed October 2026.

More about Riyadh that matters for portable equipment
Riyadh: who works there
More than 500 foreign companies have moved regional headquarters to Riyadh, alongside banks and major Saudi firms, so many equipment buyers and project teams are based in the capital.
Riyadh: climate and equipment wear
Dust storms occur in Riyadh and can cut visibility to under 10 m, so filters, port covers and sealed enclosures matter for handheld equipment.
Riyadh: logistics and access
King Khalid International Airport lies about 35 km north of the city centre and is the main hub for visitors, which sets the transfer time to inland industrial areas.
Riyadh: who works there
The industrial cities authority MODON, set up in 2001 and headquartered in Riyadh, oversees 42 industrial cities and over 7,700 productive factories across the Kingdom.
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 Riyadh. Aramco's Riyadh Refinery points to Zone 1 gas areas, and manufacturing plants add Zone 21 dust areas. A marking check should first ask gas or dust, then read the group and temperature class from the plant's classification. The IS-04Z1 target marking II 2 G Ex ib IIC T4 refers to gas only.
The route · distribution
Distributing the IS-04Z1 in Riyadh
SAMS is appointing authorised distributors ahead of the Q4 2026 launch. No territory has been granted for Riyadh yet and applications are reviewed company by company. Because a certified Ex device cannot be opened by an ordinary phone workshop without invalidating its certificate, SAMS looks for partners who can provide competent technical support and after-sales service 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 Riyadh.
- 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 · Riyadh
Frequently asked questions
Can we buy an Ex-proof smartphone in Riyadh today?
Not today. Until the certificates are issued the IS-04Z1 stays out of classified areas, and until launch there is nothing to purchase. You can ask for the datasheet and the certification schedule, or book a safe-area evaluation unit.
What does an Ex-proof smartphone in Riyadh cost?
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.
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 Riyadh would use it?
Likely candidates are refinery process units, chemical and manufacturing plants, industrial plant dust areas (zone 21). 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 Riyadh?
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 Riyadh.
Is Riyadh a hazardous-area site or a buying centre?
Mainly a buying and engineering centre. Aramco's Riyadh refinery and many factories have classified areas, but most large oil and gas sites are in the Eastern Province. Procurement teams, regional headquarters and contractors are in Riyadh even when plants are elsewhere.
Who runs the industrial cities near Riyadh?
MODON, headquartered in Riyadh, develops and oversees industrial cities across the Kingdom, but each factory operator decides its own safety and equipment rules. Check the specific tenant's HSE team for hazardous-area device approval before delivery.
What about dust areas in Riyadh factories?
Industrial plant dust areas classified Zone 21 are present. The IS-04Z1 target marking, II 2 G Ex ib IIC T4, refers to gas atmospheres, and certification is in progress. Do not assume dust suitability; ask the supplier and the plant's safety officer which marking the dust area requires.
