Crude slate
The refinery processes low-sulphur Bombay High and Nigerian crudes and high-sulphur Middle East crude, and supplies BS VI fuels to the Delhi NCR region.
Mathura in Uttar Pradesh is home to Indian Oil's inland refinery, commissioned on 19 January 1982 and now processing 8 million tonnes of crude a year. Mathura Refinery, Indian Oil's sixth refinery, was commissioned on 19 January 1982 after construction began in October 1972, so its older units are over 40 years old. Distribution partners for Mathura, Uttar Pradesh are being identified ahead of the Q4 2026 launch of the IS-04Z1.
Pre-launch · certification in progress · Launching Q4 2026
Short answer. Mathura, Uttar Pradesh 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. An operator's own vendor approval is a separate step. Certification status. Place facts reviewed October 2026.
| Check | What to look for | IS-04Z1 today |
|---|---|---|
| Ingress protection | IP rating for dust and water | IP68 design |
| Fleet management | EMM and MDM support | Android 16 with EMM and MDM |
| Explosion protection | A separate certificate and marking | In progress; not issued |
| Where it applies | Mathura, Uttar Pradesh: Product loading gantries, Pipeline pumping stations, Refinery process units | Classified by the site operator |

An intrinsically safe Android smartphone designed for Zone 1 and Zone 21 hazardous areas in Mathura 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.
The refinery processes low-sulphur Bombay High and Nigerian crudes and high-sulphur Middle East crude, and supplies BS VI fuels to the Delhi NCR region.
The refinery is about 50 km from the Taj Mahal in Agra and lies in the Delhi-Agra corridor, so road logistics are straightforward. Summers are generally hot and dusty.
Mathura has a hot semi-arid climate, which means very hot summers and relatively low rainfall.
The refinery received the Best of All Rajiv Gandhi National Quality Award in 1998, and a corporate postal stamp was issued for its environmental contribution.
The refinery processes low-sulphur Bombay High crude, imported Nigerian low-sulphur crude and high-sulphur Middle Eastern crude, so process conditions vary between crude types.
Mathura city is 162 kilometres south-east of Delhi and about 15 kilometres from Vrindavan, on the Yamuna river.
“Industrial” describes a phone built for plant conditions: sealed, drop-resistant and manageable at fleet scale through Android Enterprise. It does not by itself mean the phone may enter a classified area. Only a device with a valid explosion-protection certificate and marking may do that.
The IS-04Z1 is designed to be both an industrial Android phone (IP68, 4,000 mAh battery, 50 MP camera, Android 16 with EMM and MDM support) and an intrinsically safe one. Its explosion-protection certificates are in progress and have not been issued.
In Mathura, Uttar Pradesh. A single operator running an inland site simplifies fleet ownership, though shutdown contractors add many temporary users. MDM or EMM enrolment, which the IS-04Z1 supports, lets the operator control apps and access. Charging belongs in safe areas such as control rooms and workshops.
SAMS is appointing authorised distributors ahead of the Q4 2026 launch. No territory has been granted for Mathura, Uttar Pradesh 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.
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.
Yes by design: IP68 sealing, a 4,000 mAh battery, a 50 MP camera and Android 16 with EMM and MDM support. The explosion-protection certificates are separate and still in progress.
Likely candidates are refinery process units, crude and product tank farms, product loading gantries, pipeline pumping stations. 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 Mathura, Uttar Pradesh.
Mathura is 162 kilometres south-east of Delhi, so most visitors fly into Delhi and continue by road or rail. Agree gate access, security passes and induction times with the operator well before travelling.
The refinery was commissioned in 1982 and expanded in 1989, so units of different ages may have different layouts and classifications. Ask the operator for the current classification of each unit you visit.
It removes jetty and ship-loading areas, but process units, tank farms, loading gantries and pipeline pumping stations remain classified. Check the classification of each area you work in. Confirm with the operator which of these areas allow handheld devices.
