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. An IECEx mobile phone distributor in US LNG export terminals would carry the IS-04Z1 to these buyers once certification completes.
Pre-launch · certification in progress · Launching Q4 2026
Short answer. US LNG export terminals 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.
Where things stand: the IS-04Z1 has not launched, and none of its four certification routes has produced a certificate yet. An operator's own vendor approval is a separate step. Certification status. Place facts reviewed October 2026.

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.
A short profile of the site and the kinds of classified area that matter for portable equipment.
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.
In 2024 the United States had seven large LNG liquefaction export terminals with a combined capacity of about 88 million tonnes a year.
LNG is held at about minus 162 degrees Celsius and is not itself flammable; it must first vaporise and mix with air in a range of roughly 5 to 15 percent before it can burn.
The Lake Charles LNG terminal near Lake Charles, Louisiana, has facilities for LNG receipt, storage and regasification and is one of the few such US terminals.
Golden Pass LNG at Sabine Pass, owned 70 percent by QatarEnergy and 30 percent by ExxonMobil, has an 18 million tonne a year capacity and was due to be commissioned in 2025.
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 US LNG export terminals. Terminals such as Sabine Pass, Corpus Christi, Cameron, Calcasieu Pass, Freeport and Golden Pass involve global contractors and LNG carriers. IECEx gives these teams an international reference: a certificate of conformity with a schedule of conditions. SAMS holds no such certificate yet for the IS-04Z1.
Distribution of the IS-04Z1 is by authorised partners only, and SAMS has not yet granted a territory for US LNG export terminals. 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.
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.
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 US LNG export terminals.
Typical classified areas are around storage tanks, vaporisers, loading arms, compressor buildings and flare systems. The operator defines these with area classification drawings, so request them before any visit and confirm what approved portable equipment they accept.
LNG must vaporise and mix with air within a flammable range of roughly 5 to 15 percent before it ignites. Leaks and vents therefore create gas-hazard zones, which is why sites control portable electronics and ignition sources carefully.
Terminal operators and EPC contractors normally control equipment approvals, so the approving party depends on whether the site is operating or under construction. The IS-04Z1 has no certificate yet. Confirm requirements with the site operator or EPC before any proposal.
