Explosion-Proof Cell Phone Distributor in India
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. 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. Distribution partners for India are being identified ahead of the Q4 2026 launch of the IS-04Z1.

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.
Current position: certification in progress, nothing issued, launch targeted for Q4 2026. An operator's own vendor approval is a separate step. Certification status. Place facts reviewed October 2026.

More about India that matters for portable equipment
India: industry on the ground
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.
India: rules and approvals
A July 2025 PESO procedure accepts an IECEx certificate with test report for all manufacturers, and EU-type examination certificates only from EU-based manufacturers.
India: rules and approvals
PESO approval from the Chief Controller of Explosives is required for Ex electrical apparatus at petroleum, gas cylinder and pressure vessel premises, under rules such as the Petroleum Rules 2002.
The term · explosion proof
What “explosion proof” means for a smartphone
“Explosion proof” is the phrase most buyers use for equipment that may be taken into a classified hazardous area. Strictly, it covers several protection concepts: a flameproof enclosure (Ex d) contains an internal explosion, while intrinsic safety (Ex i) limits electrical energy so that an ignition cannot start. Phones are normally intrinsically safe, because a flameproof handset would be too heavy to carry all shift.
The IS-04Z1 uses intrinsic safety, with a marking target of Ex ib IIC T4, and is designed for Zone 1 and Zone 21. It is pre-launch, certification is in progress and no certificate has been issued.
In India. Explosion-proof and flameproof are used loosely in India, but the real choice is between concepts: flameproof Ex d for enclosures and intrinsic safety for a handset moved around plant. At refineries, gas plants and LNG jetties the IS-04Z1 is designed around intrinsic safety rather than a heavy flameproof housing.
The route · distribution
Distributing the IS-04Z1 in India
Distribution of the IS-04Z1 is by authorised partners only, and SAMS has not yet granted a territory for India. 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.
What SAMS looks for in a partner
- Operator relationships
- Existing supplier registrations or a clear route to them with the main operators and contractors in India.
- Ex-competent staff
- People who understand zone classification, markings and the conditions of a certificate.
And equally important
- Local-language support
- Documentation, training and helpdesk in the languages the workforce uses.
- Service capability
- Spares, battery replacement and repair routed through SAMS-approved channels.
Questions · India
Frequently asked questions
Can we buy an explosion proof cell phone 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 explosion proof cell phone 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.
Is the IS-04Z1 explosion proof or intrinsically safe?
It is intrinsically safe (marking target Ex ib IIC T4), which is the usual way to make a phone for hazardous areas. It is not a flameproof (Ex d) design, and certification is still in progress.
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 do I become a SAMS distributor for India?
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.
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.
