Supplier approval · Pemex
How suppliers reach Pemex
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.
Field notes · Pemex
More about Pemex that matters for portable equipment
Pemex: background
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.
Pemex: projects and investment
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.
Pemex: background
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.
The term · ATEX and IECEx
What “ATEX and IECEx” means for a smartphone
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.

Questions · Pemex
Frequently asked questions
Can Pemex buy the IS-04Z1 today?
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.
What does an ATEX and IECEx smartphone for Pemex cost?
No price is published. While certification is in progress there is no list price and no committed lead time, and a supplier quoting a firm figure for an uncertified Ex handset is promising something it cannot stand behind. Indicative pre-launch pricing is issued in writing against a stated quantity and site.
Is the IS-04Z1 ATEX and IECEx certified?
Not yet. Both routes are in progress with TÜV in Germany and no certificate has been issued. Any listing that says otherwise is wrong.
How does Pemex approve suppliers?
Supplier registration and equipment approval are run by the organisation itself; confirm current requirements with its procurement and HSE teams.
Is intrinsically safe the same as explosion proof?
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.
How does the Gulf coast climate affect phones used on Pemex facilities?
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.
Which Pemex facilities usually have Zone 1 areas?
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.
Do Pemex sites need Spanish-language device support?
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.
