JTC states that the island also hosts power generation and desalination plants and supports Singapore's natural gas supply, so work there covers utilities as well as process plants.

Ex-Proof Smartphone Distributor in Jurong Island
Jurong Island is Singapore's integrated energy and chemicals park of about 3,000 hectares, formed from seven small islands and developed by JTC. It hosts over 100 global companies in refining, olefins and chemical manufacturing, so gas and vapour (Zone 1) areas are widespread. An Ex-proof smartphone distributor in Jurong Island would carry the IS-04Z1 to these buyers once certification completes.

More about Jurong Island that matters for portable equipment
Jurong Island: industry on the ground
Singapore Refining Company runs a refinery on Jurong Island able to process 290,000 barrels of crude a day, producing fuel products and chemical feedstocks for domestic and export markets.
Jurong Island: industry on the ground
Singapore produces no crude oil or feedstock of its own, so Jurong Island plants run on imported material delivered by sea, which makes jetties, tank farms and transfer lines a constant feature of the site.
Jurong Island: infrastructure
The caverns hold about 9.2 million barrels across five isolated storage caverns and store crude oil, condensate, naphtha and gasoil, so vapour-handling surface facilities sit above a very large underground inventory.
Jurong Island: logistics and access
Visitors enter through the Jurong Island Checkpoint, where they exchange an identity card or passport for a Jurong Island visitor pass before travelling on to the plant they are visiting.
The term · Ex-proof
What “Ex-proof” means for a smartphone
“Ex-proof” is shorthand for equipment carrying an explosion-protection marking (the Ex mark) that matches the area it enters. The marking states the protection concept, gas or dust group and temperature class, and it must be backed by a certificate issued by a recognised body, so a phone described as Ex-proof should come with a certificate number you can check.
The IS-04Z1 is designed to carry the marking II 2 G Ex ib IIC T4. That is a target: certification is in progress, no certificate has been issued, and SAMS will publish the certificate numbers when they exist.
In Jurong Island. A cluster of refineries, crackers and petrochemical plants means gas groups can vary by plant, so a marking check should read zone, gas group and temperature class from each operator's classification. The IS-04Z1 target marking is II 2 G Ex ib IIC T4. Whether IIC is required is for the operator to say.

Questions · Jurong Island
Frequently asked questions
Can we buy an Ex-proof smartphone in Jurong Island 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 Ex-proof smartphone in Jurong Island cost?
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.
What Ex marking will the IS-04Z1 carry?
The marking target is II 2 G Ex ib IIC T4. It becomes a marking only when the certificate is issued; until then it is a design target.
Which areas at Jurong Island would use it?
Likely candidates are refinery and cracker process units, chemical and petrochemical plants, lng storage and loading, underground rock cavern storage. Which areas are classified, and to what zone, is set by the site operator's own area classification drawings.
How do I become a SAMS distributor for Jurong Island?
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 Jurong Island.
Are the underground storage caverns a hazardous area?
The caverns store crude oil, condensate, naphtha and gasoil, so hydrocarbon vapour hazards are expected around the facility's surface operations. The actual zone boundaries are set by the operator's area classification drawings, so confirm them before taking any portable device near the site.
How do visitors get onto Jurong Island?
Visitors typically apply for a Jurong Island visitor pass at the island checkpoint, exchanging an identity card or passport, and then collect a separate security pass at the plant. Each plant sets its own induction, escort and screening steps, so book the visit through a named sponsor.
Does underground rock cavern storage change the requirement?
Jurong Rock Caverns hold crude oil and petrochemical products below ground, adding confined-space and below-ground classified areas. The plant sets the classification and entry rules. Ask the operator which zone applies and whether handhelds are permitted, and check that the marking suits that zone.
