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. This page explains what to look for in an ATEX and IECEx mobile phone for Pemex, 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 Pemex: pre-launch, designed for Zone 1 and Zone 21 (marking target Ex ib IIC T4), with certification in progress and no certificate issued.
Where things stand: the IS-04Z1 has not launched, and none of its four certification routes has produced a certificate yet. 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 |
|---|---|---|
| Marking | II 2 G Ex ib IIC T4 on the rating plate | Design target; not yet marked |
| EU-type examination certificate | Notified body number and certificate ID | In progress with TÜV; not issued |
| IECEx certificate of conformity | Number listed on the IECEx online register | In progress; not issued |
| Where it applies | Pemex: Offshore platforms, Refinery process units, Petrochemical plants | Classified by the site operator |

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.
The main sites and the hazardous-area types a portable device is likely to meet at this organisation.
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.
ATEX is the European legal framework for equipment used in explosive atmospheres (Directive 2014/34/EU). IECEx is the international certification scheme built on the IEC 60079 standards. Buyers outside Europe often ask for both: an IECEx certificate is the technical evidence most national regimes build on, while ATEX is the legal route into the European market.
For the IS-04Z1 both routes are in progress with TÜV in Germany and neither certificate has been issued. The marking target is II 2 G Ex ib IIC T4: equipment Group II (surface industry), Category 2 (Zone 1 gas), protection concept ib (intrinsic safety), gas group IIC and temperature class T4.
In Pemex. A Pemex reviewer would expect certificate evidence before a handheld enters an offshore platform or a refinery process unit at sites such as Cadereyta, Tula or Salina Cruz. With international contractors and EPCs working on its refineries, a dual ATEX and IECEx route lets one product answer both families of paperwork. The IS-04Z1 is in certification and no certificate exists.
A short checklist for anyone writing or reviewing the specification, with the IS-04Z1 status against each point.
No. Nothing can be bought or taken into a classified area today: certification is in progress and launch is planned for Q4 2026. What is available now is the datasheet, the written certification schedule and evaluation units for safe-area use.
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.
Not yet. Both routes are in progress with TÜV in Germany and no certificate has been issued. Any listing that says otherwise is wrong.
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.
