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.

Field notes · Mexico
More about Mexico that matters for portable equipment
Mexico: rules and approvals
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procedure, which results in a Certificate of Homologation, so older IFT references in supplier paperwork may be out of date.
Mexico: rules and approvals
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.
Mexico: background
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.
The term · explosion proof
What “explosion proof” means for a smartphone
“Explosion proof” is the phrase most buyers use for equipment that may be taken into a classified hazardous area. Strictly, it covers several protection concepts: a flameproof enclosure (Ex d) contains an internal explosion, while intrinsic safety (Ex i) limits electrical energy so that an ignition cannot start. Phones are normally intrinsically safe, because a flameproof handset would be too heavy to carry all shift.
The IS-04Z1 uses intrinsic safety, with a marking target of Ex ib IIC T4, and is designed for Zone 1 and Zone 21. It is pre-launch, certification is in progress and no certificate has been issued.
In Mexico. Mexican plants say prueba de explosión loosely, but the concepts differ. Flameproof Ex d encloses a possible explosion, while the IS-04Z1 uses intrinsic safety to limit energy. At a refinery such as Dos Bocas, offshore Campeche or a petrochemical terminal at Altamira, the second concept suits a handset more than a heavy fixed fitting.

Sourcing the IS-04Z1 for Mexico
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.
- 01
Request the datasheet
The technical specification, marking target and conditions of use, sent by email.
- 02
Ask for the certification schedule
Which certificates are in progress, in what order, and what is still to be confirmed.
- 03
Evaluate in a safe area
Evaluation units can be used for connectivity, MDM enrolment and workflow testing outside classified areas.
- 04
Register for launch
Tell us the site, zone, gas group and quantity so the right authorised distributor can contact you.
Questions · Mexico
Frequently asked questions
Can we buy an explosion proof 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 explosion proof 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 explosion proof or intrinsically safe?
It is intrinsically safe (marking target Ex ib IIC T4), which is the usual way to make a phone for hazardous areas. It is not a flameproof (Ex d) design, and certification is still in progress.
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 will SAMS supply Mexico?
Through authorised distributors once certificates exist. Until then SAMS can send the datasheet and certification schedule and arrange safe-area evaluation units.
Do I need both homologation and NOM certification for a phone in Mexico?
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.
Where does hazardous-area work concentrate in Mexico?
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.
Do Mexican drawings in Clase I División 1 match a Zone 1 device?
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.
