The Port of Santos is 79 km from Sao Paulo city and is reached by the Anchieta and Imigrantes highways, which carry most import and export freight for the region. An intrinsically safe smartphone distributor in Sao Paulo state would carry the IS-04Z1 to these buyers once certification completes.

More about Sao Paulo state that matters for portable equipment
Sao Paulo state: who works there
Replan at Paulinia, in Sao Paulo state, is Petrobras' largest refinery at 434,000 b/d, and the 2024-28 plan includes new units and upgrades there.
Sao Paulo state: projects and investment
Petrobras plans revamps at the Presidente Bernardes refinery and Replan, an aviation bio-kerosene plant at RPBC and a combustion boiler at the Capuava refinery, all in Sao Paulo state.
Sao Paulo state: industry on the ground
Sao Paulo is Latin America's largest urban economy, representing around 10 percent of Brazil's GDP, and is home to the B3 stock exchange, so many contractors and procurement teams are based there.
Sao Paulo state: climate and equipment wear
São Paulo has a humid subtropical climate, and heavy storms can bring more than 140 mm of rain in 24 hours, so outdoor and plant-yard work needs weather protection for portable equipment.
The term · intrinsically safe
What “intrinsically safe” means for a smartphone
Intrinsic safety limits the electrical and thermal energy in a circuit so that neither a spark nor a hot surface can ignite a gas or dust atmosphere, even when a fault occurs. The ib level, used for Zone 1, tolerates one fault. It is the usual way to make a handheld device that a worker carries continuously through a hazardous area.
The IS-04Z1 is designed on this principle for Zone 1 and Zone 21 (marking target II 2 G Ex ib IIC T4). Intrinsic safety is a design basis, not a certificate: certification is in progress and none has been issued yet.
In Sao Paulo state. With a refinery cluster served by an extensive road network, inspection and maintenance teams may visit several plants on one trip. An intrinsically safe handheld that travels with them avoids swapping devices at each gate. The IS-04Z1 is designed for that, subject to certification.

Distributing the IS-04Z1 in São Paulo
SAMS is appointing authorised distributors ahead of the Q4 2026 launch. No territory has been granted for Sao Paulo state 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 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 intrinsically safe smartphone 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 intrinsically safe smartphone 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.
What does ‘intrinsically safe’ mean for the IS-04Z1?
The circuits are designed to limit energy so a spark or hot surface cannot ignite a gas or dust atmosphere, even with one fault (level ib, Zone 1). Certification of that design is 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.
