Ownership
HD Hyundai Oilbank and Lotte Chemical each hold 50% and each contributed 600 billion won.
Daesan is a petrochemical complex in Seosan, South Chungcheong Province, on the Yellow Sea coast. Upgrades completed by 2021 lifted Daesan capacity to about 1.5 million tonnes a year of ethylene and 1.1 million of propylene, and let the plant also crack propane. Distribution partners for Daesan are being identified ahead of the Q4 2026 launch of the IS-04Z1.
Pre-launch · certification in progress · Launching Q4 2026
Short answer. Daesan 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.
For the record, no certificate exists for the IS-04Z1 today. The programme is under way ahead of a Q4 2026 launch. 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 |
|---|---|---|
| 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 | Daesan: Tank farms, Hydrogen handling, Naphtha cracker and petrochemical units | Classified by the site operator |

An intrinsically safe Android smartphone designed for Zone 1 and Zone 21 hazardous areas in Daesan. 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 Oilbank and Lotte Chemical each hold 50% and each contributed 600 billion won.
A hydrogen shipment centre began operating at the Daesan plant in November 2025.
HD Hyundai Chemical is owned 60% by HD Hyundai Oilbank and 40% by Lotte Chemical, and in late 2025 the partners agreed to consolidate their Daesan naphtha crackers, subject to ministry approval.
Seosan had a population of roughly 175,000 in the 2017 census, which sets the scale of the local labour pool beside the coastal industrial area.
Daesan lies within Seosan city on the Yellow Sea coast of South Chungcheong Province, about 125 km south of Seoul and 34 km north-west of Naepo New Town.
The Daesan refining and petrochemical platform is a 50/50 joint venture between Hanwha and TotalEnergies, commissioned in 1991 and covering about 3.3 million square metres, making fuels and polymers on one integrated site.
“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 Daesan. The Daesan plant is run by a newly merged operator, so contractor lists and device policies may be in transition. A managed fleet under EMM or MDM should follow whichever approval route the operator confirms, with enrolment before arrival. Charging belongs in safe areas.
SAMS is appointing authorised distributors ahead of the Q4 2026 launch. No territory has been granted for Daesan yet and applications are reviewed company by company. Because a certified Ex device cannot be opened by an ordinary phone workshop without invalidating its certificate, SAMS looks for partners who can provide competent technical support and after-sales service 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.
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.
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 naphtha cracker and petrochemical units, refinery process units, tank farms, hydrogen handling. 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 Daesan.
Each plant sets its own rules for portable electronics and controls entry with permits and inductions. Typically only devices with the certification the operator specifies are allowed in classified areas, so confirm the requirement with the plant's safety department first.
A transport hub location helps, since expressways link it to Seoul and Daejeon, so replacements can usually arrive within a day or two. Confirm lead times with your supplier and keep spare batteries and chargers on site for continuous operations.
Daesan now has H&L Advanced, a merged petrochemical business owned half each by HD Hyundai Oilbank and Lotte Chemical, alongside the refinery operator HD Hyundai Oilbank. Procurement routes may still be changing. Confirm requirements with the site operator before sending documents.
