Port and industry
Incheon ranks second after Busan and has industrial complexes at Bupyeong, Juan and Namdong.
Incheon is South Korea's second largest port, west of Seoul, and forms the heart of the Capital Industrial Region with the Bupyeong, Juan and Namdong industrial complexes. KOGAS runs an LNG terminal there, where tank and send-out areas create Zone 1 and Zone 2 conditions. An Ex-proof smartphone distributor in Incheon would carry the IS-04Z1 to these buyers once certification completes.
Pre-launch · certification in progress · Launching Q4 2026
Short answer. Incheon 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 |
|---|---|---|
| Ex marking | Group, category, protection concept, gas group, temperature class | II 2 G Ex ib IIC T4 (target) |
| Gas group | IIA, IIB or IIC matched to the area drawing | IIC (target) |
| Temperature class | T-class below the ignition temperature of the gas | T4, 135 °C (target) |
| Where it applies | Incheon: Gas send-out, Industrial complex chemical handling, LNG storage tanks | Classified by the site operator |

An intrinsically safe Android smartphone designed for Zone 1 and Zone 21 hazardous areas in Incheon. 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.
Incheon ranks second after Busan and has industrial complexes at Bupyeong, Juan and Namdong.
KOGAS operates the Incheon terminal, one of its regasification terminals, which began operating in 1996.
A programme launched in 2007 aims to make Incheon as proficient in English as Singapore, which suggests English is more widely usable in the Free Economic Zone than in most Korean industrial cities.
In 2003 Incheon became South Korea's first free economic zone, and large local and global companies have since invested in the Incheon Free Economic Zone, including bio-industry projects at Songdo.
Incheon has a humid subtropical climate with four distinct seasons, cold north-westerly winds in winter and warm south-westerly gusts in summer, plus a strong urban heat island effect.
Incheon International Airport and Incheon Port make the city a transport hub for north-east Asia, and port traffic is large enough to classify it as a large-port metropolis.
“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 Incheon. Tank and send-out areas at the terminal create Zone 1 and Zone 2 conditions, and the main gas is methane, normally Group IIA. Chemical handling in the Bupyeong, Juan and Namdong complexes may involve other gases. The IS-04Z1 target marking is II 2 G Ex ib IIC T4, not yet issued.
A distributor for Incheon would carry the IS-04Z1 after certification completes; the Q4 2026 launch is the planning date and no appointment has been made. SAMS reviews applicants one by one and prefers companies with their own Ex-competent technical and service staff, since certified devices must not be repaired outside approved channels.
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.
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.
Likely candidates are lng storage tanks, lng jetty and loading, gas send-out, industrial complex chemical 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 Incheon.
English is promoted through the Incheon Free English Zone programme and is more widely used in the Free Economic Zone, but safety documents at industrial plants are normally in Korean. Ask the operator whether English induction materials are available.
Yes. The airport and the port are both major hubs, and Incheon sits next to Seoul and the Capital Industrial Region. Air freight is quick, but allow time for customs, radio and safety approvals, and confirm requirements with your forwarder.
Winters on the west coast are cold, and low temperatures reduce battery capacity in any phone. The IS-04Z1 has a 4,000 mAh battery and certification in progress, with no cold-weather figures stated here. Ask for a trial in winter conditions and confirm with the site operator.
