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

The term · IECEx
What “IECEx” means for a smartphone
IECEx is the international scheme for certifying equipment used in explosive atmospheres. A certificate of conformity is issued by an accredited certification body against a specific edition of the IEC 60079 standards and carries a schedule of conditions of safe use. It is not a legal requirement in most countries on its own, but many national schemes accept it as the technical basis.
The IECEx certificate for the IS-04Z1 is in progress and has not been issued. The marking target is Ex ib IIC T4, the intrinsic safety concept for Zone 1 gas with the hardest gas group (IIC) and a 135 °C temperature class.
In Duque de Caxias. Petrobras plans US$4.6 billion for Reduc in 2026-2030, which may bring international EPCs and specialists to Duque de Caxias. IECEx offers them a familiar certificate of conformity and schedule of conditions. The IS-04Z1 IECEx certification is in progress, not held.
The route · distribution
Distributing the IS-04Z1 in Duque de Caxias
SAMS is appointing authorised distributors ahead of the Q4 2026 launch. No territory has been granted for Duque de Caxias 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 Duque de Caxias.
- 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 · Duque de Caxias
Frequently asked questions
Can we buy an IECEx mobile phone in Duque de Caxias 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 IECEx mobile phone in Duque de Caxias 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.
Does the IS-04Z1 hold an IECEx certificate?
No. The IECEx certificate is in progress and has not been issued. SAMS will publish the number when it exists.
Which areas at Duque de Caxias would use it?
Likely candidates are refinery process units, tank farms and pipelines, loading and dispatch areas, biofuel (saf and renewable diesel) processing. 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 Duque de Caxias?
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 Duque de Caxias.
How should I plan devices for a Rio de Janeiro refinery visit?
Typically choose a device with the right zone, gas group and temperature class, carry its certificate, and confirm local radio approval requirements. Many sites also require induction and an approved-equipment check at the gate, so allow time for that.
What does the refinery's lubricant and gas role mean for hazard types?
Lubricant plants and gas processing mean both flammable liquids and flammable gases can occur, sometimes with hydrocarbon vapours near ambient temperature. Ask the operator for the applicable gas groups; do not assume one device rating covers every unit.
Will the 2026 shutdowns affect when I should order?
Maintenance shutdowns of the coking and hydrotreating units are scheduled in 2026, which brings large contractor numbers into classified areas. Plan lead times early. Certification is in progress, so confirm schedules and requirements with the site operator and its HSE team.
