Mexico: rules and approvals
Mexico has two approval schemes, telecom homologation and NOM certification, and neither is mandatory for every product; which applies depends on what is being sold.

Ex-Proof Smartphone 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. 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procedure, which results in a Certificate of Homologation, so older IFT references in supplier paperwork may be out of date. An Ex-proof smartphone distributor in Mexico would carry the IS-04Z1 to these buyers once certification completes.

WhereMexico
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.
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.

Field notes · Mexico
More about Mexico that matters for portable equipment
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.
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.
The term · Ex-proof
What “Ex-proof” means for a smartphone
“Ex-proof” is shorthand for equipment carrying an explosion-protection marking (the Ex mark) that matches the area it enters. The marking states the protection concept, gas or dust group and temperature class, and it must be backed by a certificate issued by a recognised body, so a phone described as Ex-proof should come with a certificate number you can check.
The IS-04Z1 is designed to carry the marking II 2 G Ex ib IIC T4. That is a target: certification is in progress, no certificate has been issued, and SAMS will publish the certificate numbers when they exist.
In Mexico. NOM-001-SEDE follows the American structure, so a Mexican drawing may read Clase I División 1 where an international one reads Zone 1. A marking check therefore compares II 2 G Ex ib IIC T4 with whichever language the plant drawings use. The IIC group covers the hydrogen and ethylene found on Gulf coast units, and T4 should be confirmed.
The route · distribution
Distributing the IS-04Z1 in Mexico
A distributor for Mexico would carry the IS-04Z1 after certification completes; the Q4 2026 launch is the planning date and no appointment has been made. SAMS reviews applicants one by one and prefers companies with their own Ex-competent technical and service staff, since certified devices must not be repaired outside approved channels.
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 Ex-proof smartphone 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 Ex-proof smartphone in Mexico cost?
SAMS has not published a price. Any figure you are offered for an uncertified Ex phone should be treated with caution; written indicative pricing is available for a defined quantity and site.
What Ex marking will the IS-04Z1 carry?
The marking target is II 2 G Ex ib IIC T4. It becomes a marking only when the certificate is issued; until then it is a design target.
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.
