Port and hinterland
Dahej is a deep-water cargo port handling LNG, chemicals, coal and petroleum products, with a large Special Economic Zone in its hinterland and rail and road links.
Dahej is a cargo port and industrial area in Bharuch district on the Gulf of Khambhat, Gujarat. The nearest airports are at Ahmedabad, Surat and Vadodara, and Bharuch, about 45 kilometres away, is being connected to Dahej by a broad-gauge rail siding. An ATEX and IECEx smartphone distributor in Dahej, Gujarat would carry the IS-04Z1 to these buyers once certification completes.
Pre-launch · certification in progress · Launching Q4 2026
Short answer. Dahej, Gujarat 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.
For the record, no certificate exists for the IS-04Z1 today. The programme is under way ahead of a Q4 2026 launch. Operator approval runs on its own timeline. Certification status. Place facts reviewed October 2026.

An intrinsically safe Android smartphone designed for Zone 1 and Zone 21 hazardous areas in Dahej India. 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.
Dahej is a deep-water cargo port handling LNG, chemicals, coal and petroleum products, with a large Special Economic Zone in its hinterland and rail and road links.
The setting is general hot, humid coastal conditions with salty air and monsoon rain, which favours sealed, corrosion-resistant devices.
Port users include Petronet LNG, the Gujarat Chemical Port Terminal Company, ONGC OPAL, Birla Copper, Torrent Pharmaceuticals and Reliance Industries, each with its own jetty or facility.
Petronet LNG's Dahej terminal has a capacity of 17.5 million tonnes a year with eight LNG storage tanks and is being expanded to 22.5 million tonnes in two phases.
It is the first terminal in India to load LNG into trucks, with four truck-loading bays, and acts as a hub for small-scale LNG for customers without pipeline access.
The port lies in the Gulf of Cambay at the junction of the Guljaria and Ban creeks and is a natural deep-water port taking vessels with a draft of up to 25 metres.
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 Dahej, Gujarat. Dahej combines an LNG terminal, a chemical port and petrochemical plants, so a reviewer may meet evidence requests from different operators. Offering ATEX and IECEx routes helps international contractors who work across the terminal, jetties and chemical plants. The IS-04Z1 has no certificate yet, and both routes remain in progress.
SAMS is appointing authorised distributors ahead of the Q4 2026 launch. No territory has been granted for Dahej, Gujarat 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 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.
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 lng storage and regasification, ethane and propane handling, marine jetties, petrochemical plants. 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 Dahej, Gujarat.
High water can rise 10 to 11 metres, which affects vessel movements, jetty operations and marine support work. Schedules usually follow tide tables, so build flexibility into plans for jetty visits.
LNG sites typically classify areas around storage tanks, vaporisation units, jetty loading arms and truck loading bays, because vapour can form a flammable mixture with air. The operator defines the zones, so request the drawings and accepted approvals before entering.
Check ingress rating, corrosion resistance of connectors and seals, and how the device is stored between shifts. Heavy rain, salty air and heat all matter. IP68 helps with water, but explosion protection comes only from the marking. Ask the operator about its portable equipment rules in wet weather.
