United States: industry on the ground
The Permian also yields potash, mined by the room-and-pillar method in Lea and Eddy counties in New Mexico, which adds mining and mineral-dust hazards to the oil and gas activity.
The IS-04Z1 is built for people who work inside classified locations at American refineries, gas plants, terminals and wellsites, and for the HSE and IT teams who decide what goes through the gate. This page sets out how an NEC 500 Class I Division 1 mobile phone supply route to United States will work for the IS-04Z1, and what is and is not available before launch.
Pre-launch · certification in progress · Launching Q4 2026
Short answer. An NEC 500 Class I Division 1 mobile phone for United States 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.
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 United States. It is pre-launch: IECEx, ATEX and NEC 500 certification is in progress ahead of the Q4 2026 launch.

The Permian also yields potash, mined by the room-and-pillar method in Lea and Eddy counties in New Mexico, which adds mining and mineral-dust hazards to the oil and gas activity.
For Zone approval the ANSI/UL and ANSI/ISA 60079 series apply, and ordinary-location electrical safety standards such as ANSI/UL 61010 must also be met.
The Permian Basin in West Texas and south-eastern New Mexico covers more than 86,000 square miles and extends about 250 miles wide and 300 miles long, so sites are spread over a very large area.
The Permian is the highest-producing US oil field, averaging 4.2 million barrels of crude a day in 2019, with Midland, Odessa and San Angelo serving as headquarters towns.
North America classifies hazardous locations by Class and Division under the National Electrical Code (NEC 500, with NEC 505 as the zone-based alternative); Canada uses the Canadian Electrical Code. Class I Division 1 is the closest counterpart to Zone 1 for flammable gases and vapours. Equipment must be listed by a nationally recognised testing laboratory.
NEC 500 Class I Division 1 is one of the four routes in the IS-04Z1 certification programme. It is in progress and no listing has been issued.
In United States. In the US the working language is Class and Division, where Zones are an alternative; the IS-04Z1 targets Zone 1 and Zone 21 and also pursues Class I Division 1. A reviewer should read both together: Class I covers gas, Division 1 where ignitable concentrations are normally present, and the listing is in progress, so check the final marking.
There is no stock to order for United States yet. The IS-04Z1 is pre-launch, certification is in progress, and supply will run through authorised distributors after the certificates are issued. Procurement teams can prepare now with the datasheet, the certification schedule and a safe-area evaluation.

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.
No. Nothing can be bought or taken into a classified area today: certification is in progress and launch is planned for Q4 2026. What is available now is the datasheet, the written certification schedule and evaluation units for safe-area use.
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.
NEC 500 Class I Division 1 is part of the certification programme and is in progress. No listing has been issued.
The market guide for United States covers Permian Basin, Houston Ship Channel, Beaumont and Port Arthur, Lake Charles and Calcasieu, 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.
The basin is dry and sparsely built, so summer heat, dust and long drives between sites are typical. Check the operating temperature range, dust ingress rating and battery life, and confirm any operator-specific site rules, including permits and gas detection practice, with the company controlling the lease.
Radio-containing devices such as phones normally need FCC equipment authorisation, either by certification through an approved body or a supplier's declaration depending on the device type. Check the FCC rules and consult an accredited test lab or telecommunication certification body for your product's category.
The Zone 21 design target covers dust at sulfur handling, coal transfer and solids charging, but certification is in progress and no listing exists. Check which Class and Division the final listing covers against your facility's own classification before use.
