India: geography and layout
The largest crude reserves are in the Western Offshore region at 37 per cent and Assam at 27 per cent, so both offshore platforms and remote north-eastern fields matter.
The IS-04Z1 is designed for people who work inside classified areas at Indian refineries, gas plants, LNG jetties and API blocks: field operators, inspection engineers, shift in-charges, and the HSE and materials teams whose sign-off a device has to survive. The Jamnagar refinery in Gujarat, commissioned in July 1999, now has installed capacity of 1.24 million barrels a day, the most at any single location in the world. An Ex-proof mobile phone distributor in India would carry the IS-04Z1 to these buyers once certification completes.
Pre-launch · certification in progress · Launching Q4 2026
Short answer. India 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.
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. Operator approval runs on its own timeline. Certification status. Place facts reviewed October 2026.

|---|---|---|
| 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 | India: Hazira and Surat, Vadodara, Koyali, Ankleshwar, Mumbai and the offshore basin | Classified by the site operator |

An intrinsically safe Android smartphone designed for Zone 1 and Zone 21 hazardous areas in India. It is pre-launch: IECEx, ATEX and NEC 500 certification is in progress ahead of the Q4 2026 launch.
The classified areas, operators and sites below are the ones covered in the SAMS India market guide.
The largest crude reserves are in the Western Offshore region at 37 per cent and Assam at 27 per cent, so both offshore platforms and remote north-eastern fields matter.
Imports are applied for by an Indian service provider or distributor, and there is no separate PESO mark; the Ex marking and the approval letter show compliance.
India imports 82 per cent of its oil needs, so import terminals, tank farms and coastal refineries are central to supply.
India's first oil deposits were found near Digboi in Assam in 1889, and its gas industry began in the 1960s with discoveries in Assam and the Mumbai High field.
“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 India. An Indian marking check would compare the device's gas group, temperature class and category with the zone plan at the refinery, gas plant or jetty. Hydrocarbon areas and offshore platforms may differ in their needs, set by the operator. The IS-04Z1 marking target is II 2 G Ex ib IIC T4, and it is not yet granted.
A distributor for India would carry the IS-04Z1 after certification completes; the Q4 2026 launch is the planning date and no appointment has been made. SAMS reviews applicants one by one and prefers companies with their own Ex-competent technical and service staff, since certified devices must not be repaired outside approved channels.
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.
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.
The market guide for India covers Jamnagar, Gujarat, Dahej and the Gujarat PCPIR, Hazira and Surat, Vadodara, Koyali, Ankleshwar, among others. Site-level pages are linked below.
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 India.
PESO approval is required for Ex electrical apparatus at petroleum, gas cylinder and pressure vessel premises, and imports are applied for through an Indian service provider or distributor. Whether it applies to a given site depends on the licensing category, so ask the site's safety team and a PESO consultant.
Typically the large coastal refineries such as Jamnagar, offshore platforms in the Western Offshore region, petrochemical and fertiliser complexes, and gas fields in Assam and Gujarat. Each operator issues its own area classification, so request the drawing, gas group and temperature class first.
The market guide lists PESO, BIS and WPC approvals as in progress, alongside IECEx. None has been granted yet. Which are needed for a given site depends on the operator and the regulator, so ask the site operator and check the current status before ordering.
