Pemex: projects and investment
In September 2021 Pemex and Braskem agreed a gas supply deal and a 400 million dollar ethane terminal at Laguna de Pajaritos in Coatzacoalcos, Veracruz, adding petrochemical handling in the south-east.
Pemex is Mexico's state-owned oil company, founded in 1938, producing crude oil, natural gas, fuels and petrochemicals. It owns six refineries (Cadereyta, Madero, Minatitlan, Salamanca, Salina Cruz and Tula) and the newer Dos Bocas refinery, and operates offshore fields such as Cantarell in the Bay of Campeche. If you are specifying an intrinsically safe smartphone for Pemex, this page covers the markings, the approvals and the current certification status of the IS-04Z1.
Pre-launch · certification in progress · Launching Q4 2026
Short answer. The SAMS IS-04Z1 is the intrinsically safe smartphone covered here for Pemex: pre-launch, designed for Zone 1 and Zone 21 (marking target Ex ib IIC T4), with certification in progress and no certificate issued.
Current position: certification in progress, nothing issued, launch targeted for Q4 2026. 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 |
|---|---|---|
| Level of protection | ia, ib or ic matched to the zone | ib, for Zone 1 |
| Entity parameters | Uo, Io and Po within the device limits | Published with the certificate |
| Accessories | Chargers and cases certified with the device | Defined at certification |

An intrinsically safe Android smartphone designed for Zone 1 and Zone 21 hazardous areas in Mexico. It is pre-launch: IECEx, ATEX and NEC 500 certification is in progress ahead of the Q4 2026 launch.
A short profile of its operations and the kinds of classified area that matter for portable equipment.
Supplier registration and equipment approval are run by the organisation itself; confirm current requirements with its procurement and HSE teams. The Ex certificate and an organisation's own vendor or engineering approval are two separate timelines; SAMS is working towards both and holds neither today.
In September 2021 Pemex and Braskem agreed a gas supply deal and a 400 million dollar ethane terminal at Laguna de Pajaritos in Coatzacoalcos, Veracruz, adding petrochemical handling in the south-east.
Pemex was established by presidential decree on 7 June 1938, following the nationalisation of the oil industry that March, and has since been run as the Mexican state petroleum corporation.
The Dos Bocas refinery plant opened in 2024 and was reported to be operating at 60% of capacity, transforming about 340,000 barrels a day of crude into fuels, so new-build units are being commissioned.
Small quantities of oil were first refined into kerosene around 1876 near Tampico, showing that the Gulf coast oil area has a very long industrial history and ageing plant in places.
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 Pemex. Operators on Bay of Campeche platforms and in refinery units walk long routes with many inspection points. A handheld intrinsically safe phone allows tag scanning, photographs and defect reports inside the classified area. It would suit routine rounds at Madero, Minatitlan and Tula and the crowded work periods of plant turnarounds.
A short checklist for anyone writing or reviewing the specification, with the IS-04Z1 status against each point.
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.
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.
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.
Supplier registration and equipment approval are run by the organisation itself; confirm current requirements with its procurement and HSE teams.
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.
Gulf of Mexico and Veracruz sites are typically hot, humid and salty, with heavy rain in the wet season. For handheld devices that means checking sealing, corrosion resistance and operating temperature, and asking the facility about its own environmental limits.
Typical Zone 1 and Zone 2 areas occur at refineries, gas processing and petrochemical plants, offshore platforms, LPG terminals and pipeline stations. Actual classification is facility-specific, so request area classification drawings from the operator before choosing portable equipment.
In practice yes, since operators and maintenance crews work in Spanish. Check that the interface, MDM policies and documentation can be provided in Spanish before any pilot. The IS-04Z1 runs Android 16 with EMM/MDM support, but no certificate has been issued, and SAMS has appointed no Mexican distributor.
