Industrial use
Tuas was resettled in the 1970s and developed for industry; heavy industry is present, though less than on Jurong Island.

ATEX and IECEx Mobile Phone in Tuas Industrial Zone
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. Classified areas arise mainly at shipyards, dangerous-goods chemical handling and process plants. This page explains what to look for in an ATEX and IECEx mobile phone for Tuas, and where the IS-04Z1 stands against that list today.

The term · ATEX and IECEx
What “ATEX and IECEx” means for a smartphone
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 Tuas. A reviewer in Tuas would expect ATEX and IECEx evidence for any handheld used in shipyards and fuel or chemical handling, because yard crews, vessel owners and contractors come from several countries. The IS-04Z1 certification is in progress and only a datasheet exists now. Each tenant or yard sets what it accepts.

Questions · Tuas Industrial Zone
Frequently asked questions
Can we buy an ATEX and IECEx mobile phone in Tuas Industrial Zone today?
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.
What does an ATEX and IECEx mobile phone in Tuas Industrial Zone cost?
There is no list price yet. SAMS gives indicative pre-launch pricing in writing, against a stated quantity and site, and does not commit to a lead time before certification completes.
Is the IS-04Z1 ATEX and IECEx certified?
Not yet. Both routes are in progress with TÜV in Germany and no certificate has been issued. Any listing that says otherwise is wrong.
Which areas at Tuas would use it?
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.
Is intrinsically safe the same as explosion proof?
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.
How do equipment suppliers reach Tuas sites?
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.
Are there dust hazards as well as gas?
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.
Does the Tuas Megaport change anything for device buyers?
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.
