Ex-Proof Smartphone Distributor in Rio de Janeiro
Rio de Janeiro is the headquarters city of Petrobras and a base for Brazil's offshore oil industry. Hazardous-area work in the surrounding state is at refineries, terminals and shipyards in neighbouring municipalities such as Duque de Caxias, Angra dos Reis, Itaborai and Niteroi. An Ex-proof smartphone distributor in Rio de Janeiro would carry the IS-04Z1 to these buyers once certification completes.

More about Rio de Janeiro that matters for portable equipment
Rio de Janeiro: background
Petrobras was created in 1953; its Reduc refinery started up near Rio in 1961 and its Cenpes research centre was founded in 1963, giving the city a long record in refining and technology.
Rio de Janeiro: geography and layout
The 2007 and 2008 Santos Basin pre-salt discoveries (Tupi, Jupiter and Sugar Loaf) lie about 300 km off the coast of Rio de Janeiro, tying the city to deepwater supply and service work.
Rio de Janeiro: logistics and access
Galeao International Airport lies on Governador Island in Guanabara Bay, while Santos Dumont Airport is the city's second airport, so equipment and visitors can arrive at two separate airfields.
Rio de Janeiro: background
Rio was founded in 1565, became seat of the Portuguese court in 1808 and stands on Guanabara Bay, with the Rio-Niteroi Bridge a landmark route to the Niteroi side of the bay.
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 Rio de Janeiro. A marking check begins by asking which site the handset will enter: Reduc, a Guanabara Bay shipyard, a tank terminal or an offshore base. Each classification differs. Compare zone, gas group and temperature class with the label. The IS-04Z1 target marking II 2 G Ex ib IIC T4 is not yet certified.
The route · distribution
Distributing the IS-04Z1 in Rio de Janeiro
SAMS is appointing authorised distributors ahead of the Q4 2026 launch. No territory has been granted for Rio de Janeiro 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 Rio de Janeiro.
- 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 · Rio de Janeiro
Frequently asked questions
Can we buy an Ex-proof smartphone in Rio de Janeiro 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 Rio de Janeiro 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 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 Rio de Janeiro would use it?
Likely candidates are refinery process units (duque de caxias), shipyards and fpso yards, tank terminals, offshore support bases. 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 Rio de Janeiro?
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 Rio de Janeiro.
Why do hazardous-area suppliers register in Rio de Janeiro?
Petrobras' headquarters and many engineering and procurement offices are there, so supplier registration, technical approvals and tender contacts are usually handled in the city. Confirm the current registration route with Petrobras or the lead contractor.
How far are the pre-salt fields from Rio de Janeiro?
The headline pre-salt discoveries sit roughly 300 km off the coast of Rio de Janeiro in the Santos Basin, so crews and cargo normally move through coastal bases and helicopter operations. Confirm the route with the operator.
Do I need an Ex handset for office work in Rio?
Not for ordinary office or headquarters use, because the city itself is not a plant. You would need one for visits to refineries, terminals and shipyards in the surrounding state. Confirm the rules of each operator before travelling.
