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procedure, which results in a Certificate of Homologation, so older IFT references in supplier paperwork may be out of date.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 · industrial
What “industrial” means for a smartphone
“Industrial” describes a phone built for plant conditions: sealed, drop-resistant and manageable at fleet scale through Android Enterprise. It does not by itself mean the phone may enter a classified area. Only a device with a valid explosion-protection certificate and marking may do that.
The IS-04Z1 is designed to be both an industrial Android phone (IP68, 4,000 mAh battery, 50 MP camera, Android 16 with EMM and MDM support) and an intrinsically safe one. Its explosion-protection certificates are in progress and have not been issued.
In Mexico. Contractor fleets here turn over quickly, with turnaround crews from firms such as ICA Fluor and Techint arriving and leaving at short notice. Android 16 with EMM and MDM lets a telecoms team enrol, restrict and wipe devices, with Spanish from the first screen. Charging belongs in a safe area, away from the plant fence line.
The route · specification
Specifying an industrial cell phone for Mexico
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 · Mexico
Frequently asked questions
Can we buy an industrial cell phone in Mexico 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 industrial cell 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 an industrial phone as well as an Ex phone?
Yes by design: IP68 sealing, a 4,000 mAh battery, a 50 MP camera and Android 16 with EMM and MDM support. The explosion-protection certificates are separate and 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.
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.
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.
