Inland site
Mathura is inland and is supplied with crude through the Salaya-Mathura pipeline, a 2,663 km line from the Gujarat coast, so there is no marine terminal.
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. Process units and product storage define its Zone 1 areas. An Ex-proof smartphone distributor in Mathura, Uttar Pradesh would carry the IS-04Z1 to these buyers once certification completes.
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. A buyer's engineering review is separate from the certificate. Certification status. Place facts reviewed October 2026.

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.
The companies on site and the hazardous-area types a handset is likely to meet there.
Mathura is inland and is supplied with crude through the Salaya-Mathura pipeline, a 2,663 km line from the Gujarat coast, so there is no marine terminal.
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.
Crude arrives through the Salaya-Mathura pipeline, which also supplies the Panipat and Baroda refineries, so feedstock supply is a shared pipeline network.
It was designed for 6.0 million tonnes a year, expanded to 7.5 million tonnes in 1989 and now processes about 8.0 million tonnes annually.
The refinery is located about 50 kilometres from the Taj Mahal, in the Agra-Mathura part of Uttar Pradesh.
The refinery began producing BS VI standard fuels for Delhi NCR ahead of the April 2020 mandate, showing continuing upgrade work.
“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 Mathura, Uttar Pradesh. A marking check at Mathura would be set against process units, product tank farms and loading gantries. Fuel areas often fall in lower gas groups, though hydrogen-containing units differ. The IS-04Z1 target marking is II 2 G Ex ib IIC T4, and the operator's classification decides suitability.
A distributor for Mathura, Uttar Pradesh 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 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.
SAMS has not published a price. Any figure you are offered for an uncertified Ex phone should be treated with caution; written indicative pricing is available for a defined quantity and site.
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.
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.
