Refinery
HPCL describes Visakh as India's first east-coast refinery (1957), with a single point mooring for crude carriers, and reports a record 16.04 million tonne throughput in 2025-26 after a residue upgradation facility was commissioned.
Visakhapatnam is a major east-coast port city in Andhra Pradesh. HPCL's Visakh Refinery, rated at 15 million tonnes a year after its modernisation, and an underground strategic crude reserve operated by ISPRL create Zone 1 areas in process units, tank farms and storage caverns. Distribution partners for Visakhapatnam (Vizag), Andhra Pradesh are being identified ahead of the Q4 2026 launch of the IS-04Z1.
Pre-launch · certification in progress · Launching Q4 2026
Short answer. Visakhapatnam (Vizag), Andhra 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.
Where things stand: the IS-04Z1 has not launched, and none of its four certification routes has produced a certificate yet. Operator approval runs on its own timeline. Certification status. Place facts reviewed October 2026.

An intrinsically safe Android smartphone designed for Zone 1 and Zone 21 hazardous areas in Visakhapatnam 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.
HPCL describes Visakh as India's first east-coast refinery (1957), with a single point mooring for crude carriers, and reports a record 16.04 million tonne throughput in 2025-26 after a residue upgradation facility was commissioned.
ISPRL's Visakhapatnam facility, with 1.33 million tonnes of crude storage in rock caverns and tanks, was built under India's phase-I strategic reserve programme.
HPCL's Visakh refinery was the first refinery on India's east coast, commissioned in 1957, and now has a nameplate capacity of 15 million tonnes a year, so liquid-hydrocarbon hazardous areas are extensive and long established.
Visakhapatnam has a tropical savanna climate with mean temperatures from about 25 to 31 degrees Celsius, a record high of 42 degrees, and about 1,119 mm of rain a year from south-west and north-east monsoons.
The city is the zonal headquarters of the South Coast Railway Zone, and a transit corridor is proposed to link the planned Bhogapuram airport with city business districts and the Atchutapuram industrial clusters.
The port serves the Visakhapatnam Steel Plant, quoted at about 7.3 million tonnes a year, and the industrial hinterland of Andhra Pradesh, Telangana, Odisha and Chhattisgarh, which brings coal, ore and dust hazards alongside oil and gas.
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 Visakhapatnam (Vizag), Andhra Pradesh. IECEx is the scheme visiting contractors and international engineering firms tend to know when working on east-coast refinery or storage projects. A certificate of conformity plus schedule of conditions would be the reference documents. For the IS-04Z1 neither has been issued, so it cannot yet be written into a specification.
Distribution of the IS-04Z1 is by authorised partners only, and SAMS has not yet granted a territory for Visakhapatnam (Vizag), Andhra Pradesh. 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.
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.
No price is published. While certification is in progress there is no list price and no committed lead time, and a supplier quoting a firm figure for an uncertified Ex handset is promising something it cannot stand behind. Indicative pre-launch pricing is issued in writing against a stated quantity and site.
No. The IECEx certificate is in progress and has not been issued. SAMS will publish the number when it exists.
Likely candidates are refinery process units, crude and product tank farms, underground strategic crude storage, port petroleum berths and single point mooring. 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 Visakhapatnam (Vizag), Andhra Pradesh.
Yes. Rainfall of roughly 1,100 mm a year, mostly in the monsoons, plus coastal humidity and salt air, mean outdoor users usually want good ingress protection, sealed ports and regular cleaning of connectors. Check the rating against your site specification.
The main clusters are the HPCL Visakh refinery, the port with its bulk cargo handling, the steel plant and its coal and ore supply chain, and the shipyards. Gas, vapour and combustible dust zones all arise, so confirm the classification with each site.
Not by default. Entry of electronic devices is governed by the operator's permit and equipment approval rules, which contractors must follow. A device in certification would normally need operator acceptance first. Confirm with the site operator's HSE team before planning any trial.
