Ex-Proof Mobile Phone Distributor in São Paulo
Sao Paulo is Brazil's largest city and an industrial 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 Ex-proof mobile phone distributor in Sao Paulo state would carry the IS-04Z1 to these buyers once certification completes.

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 Sao Paulo state. A marking check should be done per refinery, since Replan, Revap, RPBC and Recap have different units and products. Compare zone, gas group and temperature class with the plant classification. The IS-04Z1 target marking II 2 G Ex ib IIC T4 is not yet certified.

Questions · São Paulo
Frequently asked questions
Can we buy an Ex-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 Ex-proof mobile phone in São Paulo 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 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.
