United States: rules and approvals
The FCC regulates radio frequency devices between 9 kHz and 3000 GHz, and most radio-containing products must follow an equipment authorisation procedure before being marketed.

Field notes · United States
More about United States that matters for portable equipment
United States: rules and approvals
Zone-rated equipment in the US carries the AEx marking, for example Class I, Zone 0, AEx ia IIC T6, so a datasheet showing only ATEX or IECEx marks does not show US approval.
United States: rules and approvals
US workplace rules accept electrical equipment in explosive atmospheres only if it is approved by an OSHA-recognised NRTL, and OSHA states that the NRTL's specific mark is required, so CE and ATEX do not count.
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 term · rugged
What “rugged” means for a smartphone
A rugged phone is built to survive water, dust, drops and rough handling, usually rated by an IP code and a drop specification. Ruggedness is an environmental property: it says nothing about whether a phone may be used where flammable gas or dust is present. That is decided by explosion-protection certification and marking.
The IS-04Z1 combines both: an IP68 sealed rugged build and a design for Zone 1 and Zone 21 (marking target Ex ib IIC T4). The explosion-protection certificates are in progress and none has been issued.
In United States. A Permian wellpad in August and a North Dakota gas plant in January are two ends of one fleet, and the deepwater Gulf adds salt and weather. IP68 sealing and a rugged build are aimed at that range. IP68 is an ingress rating and does not by itself provide explosion protection.

The technical specification, marking target and conditions of use, sent by email.
- 02
Ask for the certification schedule
Which certificates are in progress, in what order, and what is still to be confirmed.
- 03
Evaluate in a safe area
Evaluation units can be used for connectivity, MDM enrolment and workflow testing outside classified areas.

Questions · United States
Frequently asked questions
Can we buy a rugged smartphone in United States today?
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.
What does a rugged smartphone in United States 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.
How rugged is the IS-04Z1?
It is designed to IP68 sealing, with glove-friendly controls. Ruggedness is not explosion protection: that depends on the certificates, which are in progress.
Which sites in United States does this cover?
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.
How will SAMS supply United States?
Through authorised distributors once certificates exist. Until then SAMS can send the datasheet and certification schedule and arrange safe-area evaluation units.
Is IECEx or ATEX certification enough for US hazardous locations?
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.
Do US sites use Class and Division or Zone classification?
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.
Can one handset suit both a Permian wellpad and a North Dakota gas plant?
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.
