Expansion
S-Oil's Shaheen petrochemical project was planned for completion by 2026, bringing commissioning crews.
Ulsan is a south-east coastal industrial city of about 1.1 million people, with refineries, a petrochemical complex and the world's largest shipyard. S-Oil is scheduled to complete the Shaheen Project, one of the world's largest petrochemical facilities with an investment of nine trillion won, by 2026, adding new process areas in Ulsan. An industrial mobile phone distributor in Ulsan would carry the IS-04Z1 to these buyers once certification completes.
Pre-launch · certification in progress · Launching Q4 2026
Short answer. Ulsan 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. A buyer's engineering review is separate from the certificate. Certification status. Place facts reviewed October 2026.
| Check | What to look for | IS-04Z1 today |
|---|---|---|
| Ingress protection | IP rating for dust and water | IP68 design |
| Fleet management | EMM and MDM support | Android 16 with EMM and MDM |
| Explosion protection | A separate certificate and marking | In progress; not issued |
| Where it applies | Ulsan: Tank farms, Shipyard tank and cargo-space work, Refinery process units | Classified by the site operator |

An intrinsically safe Android smartphone designed for Zone 1 and Zone 21 hazardous areas in Ulsan. It is pre-launch: IECEx, ATEX and NEC 500 certification is in progress ahead of the Q4 2026 launch.
The companies on site and the hazardous-area types a handset is likely to meet there.

HD Hyundai Heavy Industries builds tankers, LNG carriers and FPSOs at Ulsan and merged with HD Hyundai Mipo in 2025.
Ulsan is the corporate base of the Hyundai group, and SK Energy and S-Oil also operate there, so supplier registration usually runs through each company's own vendor process.
Ulsan has a monsoon-influenced humid subtropical climate, with monthly means from 2.0 degrees Celsius in January to 25.9 degrees in August and high rainfall from April to September.
The Ulsan Green Hydrogen Town project had laid 188 km of underground pipelines by October 2024 to carry hydrogen, a by-product of petrochemical complexes, to the city centre.
Ulsan was designated a Special Industrial Zone in 1962 under South Korea's first five-year plan, and Hyundai Heavy Industries founded its shipyard there in 1973, turning it into a company town.
“Industrial” describes a phone built for plant conditions: sealed, drop-resistant and manageable at fleet scale through Android Enterprise. It does not by itself mean the phone may enter a classified area. Only a device with a valid explosion-protection certificate and marking may do that.
The IS-04Z1 is designed to be both an industrial Android phone (IP68, 4,000 mAh battery, 50 MP camera, Android 16 with EMM and MDM support) and an intrinsically safe one. Its explosion-protection certificates are in progress and have not been issued.
In Ulsan. A planned petrochemical project was due for completion by 2026, bringing commissioning crews alongside ordinary shift staff. Purchasing is normally handled by the operator or its maintenance contractors, so a managed fleet under EMM or MDM should be enrolled to the right contractor. Charging belongs in safe areas.
Distribution of the IS-04Z1 is by authorised partners only, and SAMS has not yet granted a territory for Ulsan. 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 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.
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.
Yes by design: IP68 sealing, a 4,000 mAh battery, a 50 MP camera and Android 16 with EMM and MDM support. The explosion-protection certificates are separate and still in progress.
Likely candidates are refinery process units, petrochemical plants, tank farms, shipyard tank and cargo-space work. Which areas are classified, and to what zone, is set by the site operator's own area classification drawings.
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 Ulsan.
Two very large refineries, petrochemical complexes, a major shipyard, an automobile plant and a growing hydrogen network. Gas, vapour and hydrogen areas are the typical concerns, and each operator classifies its own plant, so request zone drawings before using handheld devices.
Yes. Fuel and cargo tanks, paint stores, coating bays and hot-work areas can all be treated as hazardous locations. Shipyards usually issue gas-free and hot-work permits, so ask how portable devices are controlled under those permits.
They can. Shipyards work in vessel tank and cargo spaces under permits for each vessel, while refineries classify fixed process areas, so approvals and markings may differ. The IS-04Z1 has no certificate yet. Ask each facility for its own device rules.
