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.
The IS-04Z1 is an Ex mobile phone for people working inside classified areas at Mexican refineries, offshore platforms, petrochemical plants and fuel terminals. 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. An IECEx cell phone distributor in Mexico would carry the IS-04Z1 to these buyers once certification completes.
Pre-launch · certification in progress · Launching Q4 2026
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.
Status: pre-launch. IECEx, ATEX, UKEX and NEC 500 certification is in progress and no certificate has been issued; launch is planned for Q4 2026. Operator approval runs on its own timeline. Certification status. Place facts reviewed October 2026.

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.
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.
Oil was first refined into kerosene around 1876 near Tampico, and Pemex's Tula refinery in Hidalgo is among its major inland refining sites.
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.
IECEx is the international scheme for certifying equipment used in explosive atmospheres. A certificate of conformity is issued by an accredited certification body against a specific edition of the IEC 60079 standards and carries a schedule of conditions of safe use. It is not a legal requirement in most countries on its own, but many national schemes accept it as the technical basis.
The IECEx certificate for the IS-04Z1 is in progress and has not been issued. The marking target is Ex ib IIC T4, the intrinsic safety concept for Zone 1 gas with the hardest gas group (IIC) and a 135 °C temperature class.
In Mexico. IECEx gives Mexican operators and the international contractors beside them, including Valero Mexico and Sempra Infraestructura, a common reference for Zone-based equipment. Ask for the certificate of conformity with its schedule of conditions, which states the marking and use limits. Plants here also think in Clase and División, so that mapping needs to be shown. No certificate is issued yet.
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.
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.
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.
No. The IECEx certificate is in progress and has not been issued. SAMS will publish the number when it exists.
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.
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.
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.
