The IS-04Z1 is an intrinsically safe Zone 1 and Zone 21 handset for people who work inside classified areas on Jurong Island, at Pulau Bukom and around the Tuas terminals: process operators, inspection and maintenance engineers, turnaround crews and the WSH and IT teams who equip them. Land is scarce, so Singapore stores hydrocarbons underground and builds industry on reclaimed ground: Jurong Island was formed by joining seven islands, and storage caverns free up about 150 acres of surface land. An ATEX and IECEx cell phone distributor in Singapore would carry the IS-04Z1 to these buyers once certification completes.
Pre-launch · certification in progress · Launching Q4 2026
Short answer. Singapore 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.

An intrinsically safe Android smartphone designed for Zone 1 and Zone 21 hazardous areas in Singapore. It is pre-launch: IECEx, ATEX and NEC 500 certification is in progress ahead of the Q4 2026 launch.
Operators and classified areas drawn from the SAMS Singapore market guide.
IMDA registers telecommunications equipment under a supplier's declaration approach. Cellular mobile devices, including 5G and LTE, fall under Simplified Equipment Registration, while base stations and similar higher-risk products need a recognised certification body.
An IMDA equipment registration is valid for five years, renewal is filed through the GoBusiness portal at least two months before expiry, and suppliers must keep test reports and technical files for five years.
Tuas Port opened on 1 September 2022 and is planned to reach 65 million TEU of annual handling capacity in the 2040s, which concentrates future cargo flows in the far west of the island.
Energy and chemicals is Singapore's second-largest manufacturing sector, with more than 100 global chemicals companies operating here, which keeps a steady flow of maintenance and turnaround work in classified areas.
ATEX is the European legal framework for equipment used in explosive atmospheres (Directive 2014/34/EU). IECEx is the international certification scheme built on the IEC 60079 standards. Buyers outside Europe often ask for both: an IECEx certificate is the technical evidence most national regimes build on, while ATEX is the legal route into the European market.
For the IS-04Z1 both routes are in progress with TÜV in Germany and neither certificate has been issued. The marking target is II 2 G Ex ib IIC T4: equipment Group II (surface industry), Category 2 (Zone 1 gas), protection concept ib (intrinsic safety), gas group IIC and temperature class T4.
In Singapore. A Singapore HSE or procurement reviewer on Jurong Island would expect IECEx evidence, since the sheet names IECEx and IMDA registration as the route in progress. ATEX alongside it helps the multinational operators and EPCs whose global standards already reference both. No certificate has been issued for the IS-04Z1, so any review today concerns the schedule and the datasheet.
Distribution of the IS-04Z1 is by authorised partners only, and SAMS has not yet granted a territory for Singapore. 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.
Not yet. Both routes are in progress with TÜV in Germany and no certificate has been issued. Any listing that says otherwise is wrong.

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 Singapore.
The Ministry of Manpower covers workplace safety duties for explosive atmospheres, and the Civil Defence Force covers flammable-material storage and dangerous-goods premises. In practice the site operator's own hazardous-area drawings and equipment standard decide what may enter a zone, so check them before shipping anything.
Visitors normally collect a Jurong Island visitor pass at the checkpoint, then receive a separate site pass from the plant they visit. One refinery's published rules ban phones in process and classified areas and ask visitors to declare electronic equipment. Expect similar screening and ask your sponsor in advance.
Hydrogen and acetylene, both gas group IIC, are handled on the island next to ethylene oxide in IIB, so a handset rated only to IIB cannot be used in some areas. The IS-04Z1 target is Ex ib IIC. Certification is in progress, so check the final certificate.
