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 a hazardous area 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. A hazardous area 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.
Current position: certification in progress, nothing issued, launch targeted for Q4 2026. An operator's own vendor approval is a separate step. Certification status. Place facts reviewed October 2026.
| Check | What to look for | IS-04Z1 today |
|---|---|---|
| Zone | 0, 1 or 2 for gas; 20, 21 or 22 for dust | Designed for Zone 1 and Zone 21 |
| Gas group | IIA, IIB or IIC | IIC (target) |
| Area drawing | The operator's own classification drawing | Decided by the site operator |
| Where it applies | United States: Baton Rouge corridor, Corpus Christi, Permian Basin | Classified by the site operator |

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 main operators, industrial areas and sites that the SAMS United States market guide covers.
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.
A hazardous area is a place where flammable gas, vapour or combustible dust may be present. Standards divide these into zones: Zones 0, 1 and 2 for gas and vapour, and Zones 20, 21 and 22 for dust. Zone 1 and Zone 21 are the tier where an explosive atmosphere is likely to occur in normal operation, which is where the IS-04Z1 is designed to work. Anything carried in must be marked for the zone, gas group and temperature class of the area.
No certificate has been issued for the IS-04Z1 yet, so it must not be taken into a classified area until the certificate covering it exists and the site operator has accepted it.
In United States. US classified areas range from the Permian and Williston basins to the Houston Ship Channel, Beaumont, Lake Charles, Baton Rouge, Corpus Christi, the Alaska North Slope and the deepwater Gulf. The operator or owner classifies each location. SAMS does not classify any area and designs only for a stated one.
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.

Which certificates are in progress, in what order, and what is still to be confirmed.
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.
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.
Zone 1 and Zone 21 (gas and dust) with gas group IIC and temperature class T4, subject to certification. It must not be used in a classified area before its certificate is issued and the site has accepted it.
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.
Not on its own. US workplace rules accept equipment approved by an OSHA-recognised NRTL and marked accordingly, and ATEX or IECEx certificates are not accepted in their place. Manufacturers usually need a separate US listing, so check the NRTL mark and the Class, Division or Zone marking on any device.
Both exist. Article 500 of the National Electrical Code defines the Class and Division system, and Articles 505 and 506 define Zones. Many existing refineries and gas plants are still classified by Division, so confirm which system the area drawing uses before selecting equipment markings.
IP68 sealing and a rugged build are aimed at August heat and January cold, and the 4,000 mAh battery at a shift away from the truck. The approved ambient range will come from the certificate, which is in progress, so confirm it for both extremes.
