Chemicals hub
JTC Chemicals Hub @ Tuas South (4 Tuas South Drive) is a multi-tenant development for manufacturing, blending and distribution of chemicals, including dangerous goods, with enhanced fire protection systems.
Tuas is a largely industrial planning area of 47.7 square kilometres in far western Singapore, with shipyards, heavy industry, a chemicals hub and the new Tuas Port. Tuas Port opened on 1 September 2022 and will span about 1,337 hectares with 66 berths over 26 kilometres once complete, which is shifting container operations towards the far west of the island. This page explains what to look for in an explosion proof 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. Operator approval runs on its own timeline. Certification status. Place facts reviewed October 2026.
| Check | What to look for | IS-04Z1 today |
|---|---|---|
| Protection concept | Flameproof (Ex d) or intrinsic safety (Ex i) | Intrinsic safety, level ib |
| Zone suitability | Zone 1 gas and Zone 21 dust | Design target for Zone 1 and 21 |
| Certificate | Number, issuing body and schedule of conditions | In progress; not issued |
| 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.
JTC Chemicals Hub @ Tuas South (4 Tuas South Drive) is a multi-tenant development for manufacturing, blending and distribution of chemicals, including dangerous goods, with enhanced fire protection systems.
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.
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.
Tuas was swamp and then a fishing village before being resettled in the 1970s and developed for industry, with land reclaimed off the coast from the 1980s and still expanding.
“Explosion proof” is the phrase most buyers use for equipment that may be taken into a classified hazardous area. Strictly, it covers several protection concepts: a flameproof enclosure (Ex d) contains an internal explosion, while intrinsic safety (Ex i) limits electrical energy so that an ignition cannot start. Phones are normally intrinsically safe, because a flameproof handset would be too heavy to carry all shift.
The IS-04Z1 uses intrinsic safety, with a marking target of Ex ib IIC T4, and is designed for Zone 1 and Zone 21. It is pre-launch, certification is in progress and no certificate has been issued.
In Tuas. In a shipyard or fuel store, explosion-proof is a loose term. Flameproof Ex d fits fixed equipment, while a handheld phone carried through drydock work or fuel handling relies on intrinsic safety. The IS-04Z1 is designed around that concept, with certification in progress and tenant rules still applying.
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.
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.
It is intrinsically safe (marking target Ex ib IIC T4), which is the usual way to make a phone for hazardous areas. It is not a flameproof (Ex d) design, and certification is still in progress.
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.
