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.

Field notes · India
More about India that matters for portable equipment
India: rules and approvals
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: industry on the ground
India imports 82 per cent of its oil needs, so import terminals, tank farms and coastal refineries are central to supply.
India: background
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.
The term · IECEx
What “IECEx” means for a smartphone
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 India. Indian refineries and gas plants are served by large EPC firms and international contractors. For them the IECEx certificate of conformity and schedule of conditions give a common reference, while PESO is the local route. IECEx certification for the IS-04Z1 is in progress, with PESO, BIS and WPC approvals also in progress.
The route · supply
Sourcing the IS-04Z1 for India
Supply of the IS-04Z1 to India starts only after certification, through authorised distributors. Until then a buyer can request the datasheet and the written certification schedule, and arrange a safe-area evaluation unit, which puts the site on the list for the right local channel at launch.
- 01
Request the datasheet
The technical specification, marking target and conditions of use, sent by email.
- 02
Ask for the certification schedule
Which certificates are in progress, in what order, and what is still to be confirmed.
- 03
Evaluate in a safe area
Evaluation units can be used for connectivity, MDM enrolment and workflow testing outside classified areas.
- 04
Register for launch

Questions · India
Frequently asked questions
Can we buy an IECEx smartphone in India today?
No. Nothing can be bought or taken into a classified area today: certification is in progress and launch is planned for Q4 2026. What is available now is the datasheet, the written certification schedule and evaluation units for safe-area use.
What does an IECEx smartphone in India cost?
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.
Does the IS-04Z1 hold an IECEx certificate?
No. The IECEx certificate is in progress and has not been issued. SAMS will publish the number when it exists.
Which sites in India does this cover?
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.
How will SAMS supply India?
Through authorised distributors once certificates exist. Until then SAMS can send the datasheet and certification schedule and arrange safe-area evaluation units.
Is PESO approval needed for Ex phones in 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.
Where does hazardous-area work concentrate in India?
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.
Which Indian approvals apply to this handset?
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.
