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 IS-04Z1 is an Ex mobile phone for people working inside classified areas at Mexican refineries, offshore platforms, petrochemical plants and fuel terminals. Buyers searching for an ATEX and IECEx cell phone supplier for Mexico can take the datasheet and the certification schedule for the IS-04Z1 now; supply follows certification.
Pre-launch · certification in progress · Launching Q4 2026
Short answer. An ATEX and IECEx cell phone for Mexico cannot be bought yet: the SAMS IS-04Z1 is pre-launch (certification in progress, no certificate issued), and the datasheet, certification schedule and safe-area evaluation units are available now.
Where things stand: the IS-04Z1 has not launched, and none of its four certification routes has produced a certificate yet. Operator approval runs on its own timeline. 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 |

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 classified areas, operators and sites below are the ones covered in the SAMS Mexico market guide.
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.
Telecom and wireless products follow the PEC conformity assessment procedure, which results in a Certificate of Homologation, so older IFT references in supplier paperwork may be out of date.
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.
Pemex was formed by decree on 7 June 1938 after the nationalisation of the private oil companies, and it is still state-owned and run by the government.
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.
Nothing can be bought for Mexico today: the IS-04Z1 is pre-launch, and SAMS will supply end users through authorised distributors once certificates exist. What a buyer can do now is take the specification, ask for the written certification schedule and arrange a safe-area evaluation, so that the right local channel contacts you at launch.
The technical specification, marking target and conditions of use, sent by email.
Which certificates are in progress, in what order, and what is still to be confirmed.
Evaluation units can be used for connectivity, MDM enrolment and workflow testing outside classified areas.
Tell us the site, zone, gas group and quantity so the right authorised distributor can contact you.
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.
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.
Not yet. Both routes are in progress with TÜV in Germany and no certificate has been issued. Any listing that says otherwise is wrong.
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.
Through authorised distributors once certificates exist. Until then SAMS can send the datasheet and certification schedule and arrange safe-area evaluation units.
Not always. Mexico has telecom homologation and NOM schemes, and which applies depends on the product. Radio products generally need homologation, while some electrical products also need NOM certificates for customs clearance. Confirm both requirements with a Mexican certification body before shipping.
Typically Pemex offshore platforms in the Gulf of Mexico, onshore fields and gas processing plants, refineries such as Tula, and petrochemical complexes on the Gulf coast. Each operator issues its own classification, so request the area drawing and the gas group and temperature class before specifying equipment.
They are different systems. Mexican practice follows the American code, so Clase and División is common, while the IS-04Z1 is designed for Zone 1 and Zone 21 and has an NEC 500 route in progress. The mapping is a documentation matter, so confirm acceptance with the unidad de verificación and the plant.
