Scale
The United States shipped 11.9 Bcf a day of LNG in 2024, with Louisiana's four terminals handling three-fifths. Cheniere reports 16 trains in operation across Sabine Pass and Corpus Christi.
The United States exports LNG mainly from Gulf Coast terminals in Louisiana and Texas. Zone 1 and Zone 21 areas arise at liquefaction trains, storage tanks, loading arms and gas compression. This page explains what to look for in an ATEX and IECEx mobile phone for US LNG export terminals, and where the IS-04Z1 stands against that list today.
Pre-launch · certification in progress · Launching Q4 2026
Short answer. The SAMS IS-04Z1 is the intrinsically safe smartphone covered here for US LNG export terminals: pre-launch, designed for Zone 1 and Zone 21 (marking target Ex ib IIC T4), with certification in progress and no certificate issued.
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. 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 |

An intrinsically safe Android smartphone designed for Zone 1 and Zone 21 hazardous areas in US LNG Terminals. It is pre-launch: IECEx, ATEX and NEC 500 certification is in progress ahead of the Q4 2026 launch.
The companies on site and the hazardous-area types a handset is likely to meet there.
The United States shipped 11.9 Bcf a day of LNG in 2024, with Louisiana's four terminals handling three-fifths. Cheniere reports 16 trains in operation across Sabine Pass and Corpus Christi.
Cameron LNG has three trains of about 12 mtpa. Calcasieu Pass has 10 mtpa nameplate capacity and began commercial operations on 16 April 2025. Freeport LNG is in Freeport, Texas.
LNG developments sign long-term sales contracts, typically for 20 to 25 years, before investors commit, so sites operate for decades and equipment standards stay stable.
Cheniere became the first US company to gain permission to export LNG, and its first exports came in 2016, after a long period in which terminals were designed for imports.
Cheniere's Corpus Christi site has net liquefaction capacity of 18 million tonnes a year and was reported running near its peak feed-gas rate, with expansion filed for four more trains.
In 2024 the United States had seven large LNG liquefaction export terminals with a combined capacity of about 88 million tonnes a year.
ATEX is the European legal framework for equipment used in explosive atmospheres (Directive 2014/34/EU). IECEx is the international certification scheme built on the IEC 60079 standards. Buyers outside Europe often ask for both: an IECEx certificate is the technical evidence most national regimes build on, while ATEX is the legal route into the European market.
For the IS-04Z1 both routes are in progress with TÜV in Germany and neither certificate has been issued. The marking target is II 2 G Ex ib IIC T4: equipment Group II (surface industry), Category 2 (Zone 1 gas), protection concept ib (intrinsic safety), gas group IIC and temperature class T4.
In US LNG export terminals. US LNG export terminals are built and run by international developers, EPCs and shipping interests, who commonly expect certificate evidence that works across jurisdictions. A dual ATEX and IECEx route is designed to meet that expectation. For the IS-04Z1 certification is in progress and no certificate has been issued.
A short checklist for anyone writing or reviewing the specification, with the IS-04Z1 status against each point.
Not today. Until the certificates are issued the IS-04Z1 stays out of classified areas, and until launch there is nothing to purchase. You can ask for the datasheet and the certification schedule, or book a safe-area evaluation unit.
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.
Not yet. Both routes are in progress with TÜV in Germany and no certificate has been issued. Any listing that says otherwise is wrong.
Likely candidates are liquefaction trains, lng storage tanks, ship loading berths, gas compression and pipelines. Which areas are classified, and to what zone, is set by the site operator's own area classification drawings.
Not exactly. Explosion proof is a broad everyday term; intrinsic safety is one protection concept, which limits energy so ignition cannot occur. Flameproof (Ex d) is a different concept that contains an explosion. The IS-04Z1 is intrinsically safe by design.
Export terminals run continuously, with ships loading regularly and trains shut down only for planned maintenance. Teams visiting for service or inspection need to coordinate with operations and book access well ahead.
Several US LNG sites named in federal filings, including Sabine Pass, Cameron and Corpus Christi, are on the Gulf Coast, where storm season makes shutdown and evacuation planning normal. Keep spares and agree storm-season support arrangements with the operator.
Not automatically. Each terminal has its own classification drawings and approval process, so a marking accepted at one may need separate review at another. The IS-04Z1 target is II 2 G Ex ib IIC T4, and certification is in progress. Ask each operator what documents it expects.
