LNG terminal
Shell Energy India operates the Hazira LNG terminal. The environmental clearance granted on 2 September 2025 covers expansion from 6.28 to 26.2 million tonnes a year, so this is an approved project rather than existing capacity.
Hazira is an industrial and port suburb of Surat in Gujarat, on the Tapti River about 8 km from the Arabian Sea. Its LNG terminal, gas and petrochemical plants and heavy engineering works create Zone 1 and Zone 21 areas. An Ex-proof mobile phone distributor in Hazira, Surat would carry the IS-04Z1 to these buyers once certification completes.
Pre-launch · certification in progress · Launching Q4 2026
Short answer. Hazira, Surat 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. A buyer's engineering review is separate from the certificate. Certification status. Place facts reviewed October 2026.
| Check | What to look for | IS-04Z1 today |
|---|---|---|
| Ex marking | Group, category, protection concept, gas group, temperature class | II 2 G Ex ib IIC T4 (target) |
| Gas group | IIA, IIB or IIC matched to the area drawing | IIC (target) |
| Temperature class | T-class below the ignition temperature of the gas | T4, 135 °C (target) |
| Where it applies | Hazira, Surat: Petrochemical plants, Marine terminals, LNG regasification | Classified by the site operator |

An intrinsically safe Android smartphone designed for Zone 1 and Zone 21 hazardous areas in Hazira India. It is pre-launch: IECEx, ATEX and NEC 500 certification is in progress ahead of the Q4 2026 launch.
Who operates there and which kinds of classified area a handset would meet, from the SAMS site research.
Shell Energy India operates the Hazira LNG terminal. The environmental clearance granted on 2 September 2025 covers expansion from 6.28 to 26.2 million tonnes a year, so this is an approved project rather than existing capacity.
Wikipedia lists Reliance, ONGC, Shell, NTPC, L&T and KRIBHCO among the major Hazira operators, with L&T's shipyard and heavy engineering complex alongside.
The Hazira LNG terminal in Surat district was designed for 5 million tonnes a year of regasification, expandable to 10 million tonnes depending on demand.
The monsoon starts in late June and brings about 1,200 millimetres of rain by the end of September, with maxima around 32 degrees during those months.
Surat has a tropical savanna climate moderated by the sea, with April and May the hottest months at an average maximum of about 37 degrees Celsius.
Industrial names at Hazira include Essar, Kribhco, Shell, Larsen and Toubro, NTPC, ONGC, GAIL, Gujarat State Petroleum Corporation, UltraTech Cement and Reliance's Hazira Manufacturing Division.
“Ex-proof” is shorthand for equipment carrying an explosion-protection marking (the Ex mark) that matches the area it enters. The marking states the protection concept, gas or dust group and temperature class, and it must be backed by a certificate issued by a recognised body, so a phone described as Ex-proof should come with a certificate number you can check.
The IS-04Z1 is designed to carry the marking II 2 G Ex ib IIC T4. That is a target: certification is in progress, no certificate has been issued, and SAMS will publish the certificate numbers when they exist.
In Hazira, Surat. A marking check at Hazira should distinguish gas areas, described as Zone 1, from dust areas, described as Zone 21. The gas group and temperature class come from the plant's classification, not from a general rule. The IS-04Z1 target marking is II 2 G Ex ib IIC T4, which addresses gas only.
SAMS is appointing authorised distributors ahead of the Q4 2026 launch. No territory has been granted for Hazira, Surat yet and applications are reviewed company by company. Because a certified Ex device cannot be opened by an ordinary phone workshop without invalidating its certificate, SAMS looks for partners who can provide competent technical support and after-sales service locally.
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.
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.
The marking target is II 2 G Ex ib IIC T4. It becomes a marking only when the certificate is issued; until then it is a design target.
Likely candidates are lng regasification, gas processing, petrochemical plants, marine terminals. 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 Hazira, Surat.
The terminal was opened to other companies in July 2010, which means more operators and contractors can be present on site. Each party's contractors usually follow their own induction, so confirm who controls the area you will visit.
Hazira is close to the Arabian Sea and the Tapti River, with a monsoon of about 1,200 millimetres, so humidity and salt air are normal. Choose sealed devices and ask the supplier about corrosion resistance.
Yes, the area includes both Zone 1 gas areas and Zone 21 dust areas, the latter linked to powder handling and heavy engineering. A gas marking does not cover dust. Check the dust classification with the plant operator before any device is taken into those areas.
