Monsoon climate
Mumbai has a tropical wet and dry climate with intense rain from June to September, so outdoor devices need good water and corrosion protection.
Mumbai has a deep natural harbour on the Konkan coast, a population of almost 12.5 million in 2011 and a metropolitan region of over 20 million. Refining, petroleum terminals and chemical plants create Zone 1 areas, and crude arrives from offshore fields such as Mumbai High. Distribution partners for Mumbai, Maharashtra are being identified ahead of the Q4 2026 launch of the IS-04Z1.
Pre-launch · certification in progress · Launching Q4 2026
Short answer. Mumbai, Maharashtra 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.
Where things stand: the IS-04Z1 has not launched, and none of its four certification routes has produced a certificate yet. A buyer's engineering review is separate from the certificate. Certification status. Place facts reviewed October 2026.
| Check | What to look for | IS-04Z1 today |

| Zone | 0, 1 or 2 for gas; 20, 21 or 22 for dust | Designed for Zone 1 and Zone 21 |
| Gas group | IIA, IIB or IIC | IIC (target) |

An intrinsically safe Android smartphone designed for Zone 1 and Zone 21 hazardous areas in Mumbai India. It is pre-launch: IECEx, ATEX and NEC 500 certification is in progress ahead of the Q4 2026 launch.
A short profile of the site and the kinds of classified area that matter for portable equipment.
Mumbai has a tropical wet and dry climate with intense rain from June to September, so outdoor devices need good water and corrosion protection.
The refineries sit in the Mahul-Chembur area within the metropolitan region, which Wikipedia notes is surrounded by a number of chemical plants, so site access and security controls are normally strict.
The Indian Institute of Technology Bombay and the Institute of Chemical Technology are among the major engineering schools, giving a strong local pool of chemical and process engineers.
Jawaharlal Nehru Port at Navi Mumbai, opened in 1989, has surpassed a capacity of 4 million TEU of containers, with 30 container freight stations and links to 52 inland container depots.
BPCL's Mumbai refinery was described in 2014 as having a capacity of 12 million tonnes a year, with a new 6 million tonne distillation unit replacing older units.
The port is the terminal of the Western Dedicated Freight Corridor, which is expected to raise rail capacity from 27 to 100 trains a day.
A hazardous area is a place where flammable gas, vapour or combustible dust may be present. Standards divide these into zones: Zones 0, 1 and 2 for gas and vapour, and Zones 20, 21 and 22 for dust. Zone 1 and Zone 21 are the tier where an explosive atmosphere is likely to occur in normal operation, which is where the IS-04Z1 is designed to work. Anything carried in must be marked for the zone, gas group and temperature class of the area.
No certificate has been issued for the IS-04Z1 yet, so it must not be taken into a classified area until the certificate covering it exists and the site operator has accepted it.
In Mumbai, Maharashtra. Mumbai's hazardous areas include refinery process units, petroleum storage terminals, marine oil handling and chemical plants. BPCL and HPCL classify their own areas, and neighbouring chemical plants do the same. PESO is the national regulator, and SAMS has no role in classifying or approving any area.
Distribution of the IS-04Z1 is by authorised partners only, and SAMS has not yet granted a territory for Mumbai, Maharashtra. 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.
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.
Zone 1 and Zone 21 (gas and dust) with gas group IIC and temperature class T4, subject to certification. It must not be used in a classified area before its certificate is issued and the site has accepted it.
Likely candidates are refinery process units, petroleum storage terminals, marine oil handling, chemical plants. 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 Mumbai, Maharashtra.
Mumbai has refineries in the Trombay area, including the Mumbai Refinery and BPCL's refinery. Each operator has its own access and equipment rules, so confirm with the specific site.
The Telecommunication Engineering Centre has a regional centre in Mumbai that carries out tests and issues service test certificates. Ask your supplier which certification applies to your specific handset.
Site access and security controls around the Mahul-Chembur area are normally strict. Devices may be logged or inspected at the gate, and contractors may need induction. Confirm with the site operator what documentation a new device needs before it can enter.
