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.

IECEx Smartphone for Pemex
A new Pemex unit was announced in 2021 to handle liquefied petroleum gas distribution, so LPG storage and delivery sites are also part of the group's hazardous-area footprint. 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 IECEx smartphone for Pemex, and where the IS-04Z1 stands against that list today.

WherePemex
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.
For the record, no certificate exists for the IS-04Z1 today. The programme is under way ahead of a Q4 2026 launch. A buyer's engineering review is separate from the certificate. Certification status. Place facts reviewed October 2026.

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.

More about Pemex that matters for portable equipment
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.
Pemex: projects and investment
In July 2021 the energy secretariat appointed Pemex operator of the offshore Zama field, which would feed Pemex-run facilities, showing continued activity in Gulf of Mexico shallow waters.
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 Pemex. Pemex's refineries and offshore fields draw foreign engineering firms and technology providers who are used to IECEx documents. They look for a certificate of conformity and its schedule of conditions. IECEx is a target for the IS-04Z1 and remains in progress, so Pemex staff should treat it as a planned route and not a held approval.

Specifying an IECEx smartphone for Pemex
A short checklist for anyone writing or reviewing the specification, with the IS-04Z1 status against each point.
Check on the paper
- Marking
- Equipment group, category, protection concept, gas group and temperature class, matched to the area drawing.
- Certificate and schedule
- A certificate number, issuing body and the schedule of conditions, not a brochure claim.
- Standards edition
- The IEC 60079 or national standard edition the certificate was issued against.
Check for the IS-04Z1
- Marking target
- II 2 G Ex ib IIC T4: a target, not yet a certificate.
- Certificate status
- IECEx, ATEX, UKEX and NEC 500 in progress; none issued.
- Operator approval
- Separate from the certificate and handled with the site operator.
Questions · Pemex
Frequently asked questions
Can Pemex buy the IS-04Z1 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 smartphone for Pemex 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.
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.
