South Korea: background
Ulsan was chosen as a Special Industrial Zone in 1962 and became a city in 1963, which is why large refining, petrochemical and shipbuilding sites sit close together on its coast.

Industrial Mobile Phone Distributor in South Korea
The IS-04Z1 is an intrinsically safe handset for people who cross into classified areas in South Korea every shift: refinery and petrochemical-complex operators at Ulsan and Yeosu, shipyard tank engineers, and the HSE and telecoms teams who equip them. South Korea imports nearly all its oil and was the world's third-largest importer of liquefied natural gas in 2024, so LNG terminals and fuel storage are major classified-area sites. Distribution partners for South Korea are being identified ahead of the Q4 2026 launch of the IS-04Z1.

Short answer. South Korea 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. Operator approval runs on its own timeline. Certification status. Place facts reviewed October 2026.

Field notes · South Korea
More about South Korea that matters for portable equipment
South Korea: industry on the ground
Ulsan is the industrial centre of the south-east, hosting the world's largest car assembly plant, the world's largest shipyard and the world's third-largest oil refinery, which makes it a dense mix of process and manufacturing hazards.
South Korea: geography and layout
The country has no proven oil reserves; the Donghae-1 gas field produced between 2004 and 2021 and east-coast gas exploration started in 2024, so most hazardous-area work is downstream rather than upstream.
South Korea: infrastructure
Thermal generation provides more than two thirds of electricity and nuclear power most of the rest; the first plant, Kori near Busan, opened in 1977, so large plant outages involve many contractors.
The term · industrial
What “industrial” means for a smartphone
“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 South Korea. Korean operations run predominantly in Korean, with English for international contractors and documentation, and Android 16 carries both on one build. EMM and MDM support lets the device be managed like the rest of the fleet, which matters with heavy contractor traffic at Ulsan. Charging stays in safe areas.
The route · distribution
Distributing the IS-04Z1 in South Korea
SAMS is appointing authorised distributors ahead of the Q4 2026 launch. No territory has been granted for South Korea 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.
What SAMS looks for in a partner
- Operator relationships
- Existing supplier registrations or a clear route to them with the main operators and contractors in South Korea.
- Ex-competent staff
- People who understand zone classification, markings and the conditions of a certificate.
And equally important
- Local-language support
- Documentation, training and helpdesk in the languages the workforce uses.
- Service capability
- Spares, battery replacement and repair routed through SAMS-approved channels.
Questions · South Korea
Frequently asked questions
Can we buy an industrial mobile phone in South Korea today?
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.
What does an industrial mobile phone in South Korea cost?
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.
Is the IS-04Z1 an industrial phone as well as an Ex phone?
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.
Which sites in South Korea does this cover?
The market guide for South Korea covers Ulsan, Yeosu, Daesan, Onsan, among others. Site-level pages are linked below.
How do I become a SAMS distributor for South Korea?
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 South Korea.
Is hydrogen changing hazardous-area requirements in Ulsan?
Ulsan has opened hydrogen charging stations and is developing a Green Hydrogen Town, so hydrogen gas groups may appear in new classified areas. Always check a device's gas group marking against the area classification drawing rather than assuming a general Zone 1 rating is enough.
How does Korean weather affect handheld devices used outdoors?
Summers bring concentrated heavy rainfall and humidity, and winters can be cold, so look at the operating temperature range, water ingress rating and glove-friendly touch operation. Coastal sites at Ulsan also bring salt air, which can affect ports and contacts.
Does the handset support Korean as well as English?
Android 16 carries both on one build, and operations at Korean sites run predominantly in Korean with English for international contractors and documentation. Check the language pack and the keyboard layout you require during an evaluation unit trial.
