Business base
Many industrial buyers and distributors keep offices in the city, while the plants are in other municipalities.
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. 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. This page explains what to look for in an IECEx smartphone for Sao Paulo state, and where the IS-04Z1 stands against that list today.
Pre-launch · certification in progress · Launching Q4 2026
Short answer. The SAMS IS-04Z1 is the intrinsically safe smartphone covered here for Sao Paulo state: pre-launch, designed for Zone 1 and Zone 21 (marking target Ex ib IIC T4), with certification in progress and no certificate issued.
For the record, no certificate exists for the IS-04Z1 today. The programme is under way ahead of a Q4 2026 launch. An operator's own vendor approval is a separate step. Certification status. Place facts reviewed October 2026.
| Check | What to look for | IS-04Z1 today |
|---|---|---|
| Certificate of conformity | Number checkable on the IECEx online register | In progress; not issued |
| Standards edition | The IEC 60079 edition the certificate cites | Stated on the certificate when issued |
| Schedule of conditions | Limits of use, batteries and accessories | Published with the certificate |
| Where it applies | Sao Paulo state: Refinery process units, Tank farms, Pipeline terminals | Classified by the site operator |

An intrinsically safe Android smartphone designed for Zone 1 and Zone 21 hazardous areas in São Paulo. It is pre-launch: IECEx, ATEX and NEC 500 certification is in progress ahead of the Q4 2026 launch.

Many industrial buyers and distributors keep offices in the city, while the plants are in other municipalities.
Replan alone accounts for about 20 per cent of Brazil's refining; Revap is 252,000, RPBC 170,000 and Recap 53,000 barrels a day.
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.
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.
Replan serves the interior of Sao Paulo state (about 55 percent of its output) and parts of Mato Grosso, Mato Grosso do Sul, Rondonia, Acre and southern Minas Gerais.
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.
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 Sao Paulo state. The city is a business base for international engineering and distribution firms serving plants elsewhere in the state. For them IECEx, with a certificate of conformity and schedule of conditions, provides a familiar reference. The IS-04Z1 IECEx certification is in progress, not held.
A short checklist for anyone writing or reviewing the specification, with the IS-04Z1 status against each point.
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.
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.
No. The IECEx certificate is in progress and has not been issued. SAMS will publish the number when it exists.
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.
Not exactly. Explosion proof is a broad everyday term; intrinsic safety is one protection concept, which limits energy so ignition cannot occur. Flameproof (Ex d) is a different concept that contains an explosion. The IS-04Z1 is intrinsically safe by design.
Imports usually clear through Santos and travel by highway, but customs and radio approval can add time, so allow a margin. Confirm clearance steps with a local agent early in the project.
Typically a gate induction, a permit system and equipment checks at one of Brazil's largest refineries. Confirm with the contractor which zones you will enter and whether your devices need Ex certification and local radio approval.
Not by assumption. Each plant has its own classification and procedures, and purchasing is usually through registered-supplier processes. Ask each operator for its Ex equipment policy and obtain the area classification for the specific unit before ordering.
