Port and yards
Tuas Port has operated since 2022 with 14 berths and is due to reach 18 by 2027; Seatrium's headquarters yard is at 80 Tuas South Boulevard.
Two of Singapore's four incinerators, Tuas and Tuas South, and a palm-oil renewable diesel plant completed in 2010, are located in the zone. Classified areas arise mainly at shipyards, dangerous-goods chemical handling and process plants. This page explains what to look for in an IECEx mobile phone for Tuas, and where the IS-04Z1 stands against that list today.
Pre-launch · certification in progress · Launching Q4 2026
Short answer. The SAMS IS-04Z1 is the intrinsically safe smartphone covered here for Tuas: pre-launch, designed for Zone 1 and Zone 21 (marking target Ex ib IIC T4), with certification in progress and no certificate issued.
Where things stand: the IS-04Z1 has not launched, and none of its four certification routes has produced a certificate yet. 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 |
|---|---|---|
| Certificate of conformity | Number checkable on the IECEx online register | In progress; not issued |
| Standards edition | The IEC 60079 edition the certificate cites | Stated on the certificate when issued |
| Schedule of conditions | Limits of use, batteries and accessories | Published with the certificate |
| Where it applies | Tuas: Shipyard and drydock work, Dangerous-goods chemical blending and storage, Fabrication and coating shops | Classified by the site operator |

An intrinsically safe Android smartphone designed for Zone 1 and Zone 21 hazardous areas in Tuas Industrial Zone. 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.
Tuas Port has operated since 2022 with 14 berths and is due to reach 18 by 2027; Seatrium's headquarters yard is at 80 Tuas South Boulevard.
Tuas was resettled in the 1970s and developed for industry; heavy industry is present, though less than on Jurong Island.
Tuas is bounded by the Western Water Catchment to the north, Pioneer to the east and the Straits of Johor to the west, and it has six subzones including Tuas Bay and Tuas View.
PSA plans to move its city terminals by 2027 and Pasir Panjang by 2040 into the Tuas Megaport, shifting Singapore's container operations to the west.
Seatrium's Tuas Yard at 51 Pioneer Sector 1 and its Tuas Boulevard Yard at 80 Tuas South Boulevard operate in the area, with the latter also hosting FPSO construction.
The Malaysia-Singapore Second Link opened on 2 January 1998 via Tuas, and the AYE and PIE expressways connect Tuas to the rest of Singapore.
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 Tuas. With the Tuas Megaport and shipyards drawing international vessels and visiting contractors, IECEx paperwork is a familiar reference. A certificate of conformity plus schedule of conditions is what they would ask for. The IS-04Z1 has neither yet, as certification is in progress.
A short checklist for anyone writing or reviewing the specification, with the IS-04Z1 status against each point.
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.
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.
No. The IECEx certificate is in progress and has not been issued. SAMS will publish the number when it exists.
Likely candidates are shipyard and drydock work, dangerous-goods chemical blending and storage, fabrication and coating shops. Which areas are classified, and to what zone, is set by the site operator's own area classification drawings.
Not exactly. Explosion proof is a broad everyday term; intrinsic safety is one protection concept, which limits energy so ignition cannot occur. Flameproof (Ex d) is a different concept that contains an explosion. The IS-04Z1 is intrinsically safe by design.
By road via the AYE and PIE, and by sea to the port. Most customers are inside controlled industrial sites with their own gates, so deliveries are usually scheduled and checked in advance.
Waste-to-energy and some manufacturing processes can handle combustible dusts or fine fuels, which may be classified as dust zones. Whether a given building has dust zones depends on the process; ask the operator for dust classification.
The port began operating in 2021 and is due to be fully completed by 2040, so activity is growing. Port areas where fuel or cargo vapours occur would be classified by the operator. This page does not verify any port classification, so ask the operator directly.
