Mexico: industry on the ground
Oil was first refined into kerosene around 1876 near Tampico, and Pemex's Tula refinery in Hidalgo is among its major inland refining sites.

ATEX and IECEx Mobile Phone Distributor in Mexico
The IS-04Z1 is an Ex mobile phone for people working inside classified areas at Mexican refineries, offshore platforms, petrochemical plants and fuel terminals. Applicants are described as needing in-country testing in Mexico or at a laboratory recognised under a mutual recognition agreement, plus a local representative or importer. An ATEX and IECEx mobile phone distributor in Mexico would carry the IS-04Z1 to these buyers once certification completes.

Short answer. Mexico has no appointed SAMS distributor yet: the IS-04Z1 is pre-launch (certification in progress, no certificate issued, launch planned for Q4 2026), and distributor applications are open.
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.

More about Mexico that matters for portable equipment
Mexico: rules and approvals
NOM certificates of conformity, issued by bodies such as NYCE and ANCE, allow customs clearance into Mexico, and the Secretaria de Economia oversees NOM enforcement.
Mexico: industry on the ground
The offshore Cantarell field was discovered in 1976, started production in 1979 and peaked in 2004, so ageing offshore infrastructure is a feature of Mexican upstream work.
Mexico: rules and approvals
In 2025 the IFT was dissolved and replaced by the Agencia de Transformacion Digital y Telecomunicaciones, within which the Comision Reguladora de Telecomunicaciones now issues Certificates of Homologation.
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 Mexico. A Mexican reviewer at Pemex, CFE or a Gulf coast petrochemical plant would expect the Ex evidence to arrive in a form that fits Spanish-language documentation, with the unidad de verificación dictamen as the file-closing step. ATEX and IECEx both feed that file, which helps international EPCs such as Techint and ICA Fluor, but neither replaces homologación for the radio.
The route · distribution
Distributing the IS-04Z1 in Mexico
Distribution of the IS-04Z1 is by authorised partners only, and SAMS has not yet granted a territory for Mexico. Each application is reviewed on its merits. Because opening a certified Ex handset in an ordinary workshop invalidates its certificate, the partner must be able to support and service the device locally.
What SAMS looks for in a partner
- Operator relationships
- Existing supplier registrations or a clear route to them with the main operators and contractors in Mexico.
- Ex-competent staff
- People who understand zone classification, markings and the conditions of a certificate.
And equally important
- Local-language support
- Documentation, training and helpdesk in the languages the workforce uses.
- Service capability
- Spares, battery replacement and repair routed through SAMS-approved channels.
Questions · Mexico
Frequently asked questions
Can we buy an ATEX and IECEx mobile phone in Mexico 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 mobile phone in Mexico 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.
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.
Which sites in Mexico does this cover?
The market guide for Mexico covers Dos Bocas, Tabasco, Bay of Campeche, Ciudad del Carmen, Coatzacoalcos and Minatitlán, among others. Site-level pages are linked below.
How do I become a SAMS distributor for Mexico?
Apply through the distributor page with your company details and the territory you cover. SAMS reviews applications company by company and has not yet granted a territory for Mexico.
Which Mexican body approves telecom equipment now?
Following the 2025 changes, the Comision Reguladora de Telecomunicaciones within the Agencia de Transformacion Digital y Telecomunicaciones issues Certificates of Homologation, replacing the IFT. Check the current procedures with the CRT or an accredited body, as supplier documents may still cite IFT.
What conditions should devices handle on the Gulf of Mexico coast?
Gulf coast and offshore sites typically combine heat, high humidity, salt air and seasonal storms, so check ingress protection, corrosion resistance and operating temperature range. Confirm platform transfer rules, such as helicopter battery restrictions, with the operator before deployment.
Does the IS-04Z1 need homologación in Mexico?
Radio equipment needs homologación separately from hazardous area approval, and that step is in progress alongside the explosion protection programme. No approval has been granted yet. Check with the site and your telecoms team which documents they will require before any device is enrolled.
