Explosion-Proof Mobile Phone Distributor in São Paulo
Guarulhos International Airport, also called Cumbica, is the largest airport in Brazil and Latin America, which makes it the main entry point for visiting engineers and air-freighted spares for São Paulo state. The city itself is not a refinery site, but the state hosts four Petrobras refineries: Replan at Paulinia (415,000 barrels a day), Revap, RPBC at Cubatao and Recap at Capuava. An explosion proof mobile phone distributor in Sao Paulo state would carry the IS-04Z1 to these buyers once certification completes.

WhereSão Paulo
Short answer. Sao Paulo state 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.
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.

The term · explosion proof
What “explosion proof” means for a smartphone
“Explosion proof” is the phrase most buyers use for equipment that may be taken into a classified hazardous area. Strictly, it covers several protection concepts: a flameproof enclosure (Ex d) contains an internal explosion, while intrinsic safety (Ex i) limits electrical energy so that an ignition cannot start. Phones are normally intrinsically safe, because a flameproof handset would be too heavy to carry all shift.
The IS-04Z1 uses intrinsic safety, with a marking target of Ex ib IIC T4, and is designed for Zone 1 and Zone 21. It is pre-launch, certification is in progress and no certificate has been issued.
In Sao Paulo state. The city itself is not a refinery site, so explosion-proof applies at state refineries: process units, tank farms, pipeline terminals and fuel storage and loading. Fixed gear may be flameproof Ex d, while a portable handset relies on intrinsic safety. The IS-04Z1 is designed for that, pending certification.
The route · distribution
Distributing the IS-04Z1 in São Paulo
Distribution of the IS-04Z1 is by authorised partners only, and SAMS has not yet granted a territory for Sao Paulo state. 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 Sao Paulo state.
- 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 · São Paulo
Frequently asked questions
Can we buy an explosion proof mobile phone in São Paulo today?
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.
What does an explosion proof mobile phone in São Paulo 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.
Is the IS-04Z1 explosion proof or intrinsically safe?
It is intrinsically safe (marking target Ex ib IIC T4), which is the usual way to make a phone for hazardous areas. It is not a flameproof (Ex d) design, and certification is still in progress.
Which areas at Sao Paulo state would use it?
Likely candidates are refinery process units, tank farms, pipeline terminals, fuel storage and loading. 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 Sao Paulo state?
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 Sao Paulo state.
Why do suppliers locate offices in Sao Paulo?
Because large corporations, banks and engineering contractors are based there, and Santos port is within 79 km. This does not replace site approvals, so confirm the operator's vendor registration process.
Where are the hazardous sites near Sao Paulo?
Not in the city centre but at refineries and petrochemical plants in the state, such as Replan at Paulinia, RPBC and Capuava, plus fuel terminals and pipelines. Confirm the site and its classification with the operator.
Is Sao Paulo city a hazardous area?
The city itself is not a refinery site. The state hosts four Petrobras refineries, Replan, Revap, RPBC and Recap, in other municipalities. Check which plant the handset will visit. Confirm documentation requirements with the site operator and its HSE team.
