Incheon is part of the Seoul Metropolitan Area, the world's fourth-largest by population, and its port and proximity to Seoul have driven its growth as a coastal industrial city. KOGAS runs an LNG terminal there, where tank and send-out areas create Zone 1 and Zone 2 conditions. If you are specifying an IECEx mobile phone for Incheon, this page covers the markings, the approvals and the current certification status of the IS-04Z1.

More about Incheon that matters for portable equipment
Incheon: industry on the ground
Incheon forms the heart of the Capital Industrial Region, with major industrial parks including the Bupyeong and Juan industrial complexes, so many manufacturing plants lie close to Seoul.
Incheon: background
Bio-industry is an emerging growth sector in Incheon, with biopharmaceutical production capacity described as among the largest in the world, which adds laboratory and solvent areas to the city's industrial mix.
Incheon: people and language
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.
Incheon: rules and approvals
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.
The term · IECEx
What “IECEx” means for a smartphone
IECEx is the international scheme for certifying equipment used in explosive atmospheres. A certificate of conformity is issued by an accredited certification body against a specific edition of the IEC 60079 standards and carries a schedule of conditions of safe use. It is not a legal requirement in most countries on its own, but many national schemes accept it as the technical basis.
The IECEx certificate for the IS-04Z1 is in progress and has not been issued. The marking target is Ex ib IIC T4, the intrinsic safety concept for Zone 1 gas with the hardest gas group (IIC) and a 135 °C temperature class.
In Incheon. Incheon is a major gateway port, so LNG carrier crews, inspectors and international contractors visit regularly. IECEx suits them because a certificate of conformity and schedule of conditions read the same everywhere. The IS-04Z1 has neither yet, as certification is in progress.

Questions · Incheon
Frequently asked questions
Can we buy an IECEx mobile phone in Incheon today?
No. Nothing can be bought or taken into a classified area today: certification is in progress and launch is planned for Q4 2026. What is available now is the datasheet, the written certification schedule and evaluation units for safe-area use.
What does an IECEx mobile phone in Incheon 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.
Does the IS-04Z1 hold an IECEx certificate?
No. The IECEx certificate is in progress and has not been issued. SAMS will publish the number when it exists.
Which areas at Incheon would use it?
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.
Is intrinsically safe the same as explosion proof?
Not exactly. Explosion proof is a broad everyday term; intrinsic safety is one protection concept, which limits energy so ignition cannot occur. Flameproof (Ex d) is a different concept that contains an explosion. The IS-04Z1 is intrinsically safe by design.
What hazardous activities are found around Incheon?
The industrial parks, port tank storage and fuel handling at the airport and harbour can all involve flammable gases and liquids, while bio-industry plants add chemical solvents. Each operator defines zones and permits, so ask for classification drawings for your site.
Does Incheon's climate affect handheld equipment?
The climate is mild by Korean standards, with distinct seasons, cold winter winds from the north-west and humid summers. Typical considerations are battery performance in cold weather and humidity and salt air near the port, so check device ratings against site conditions.
Is the Incheon LNG terminal the only hazardous site in Incheon?
No. Incheon also has industrial complexes at Bupyeong, Juan and Namdong with chemical handling, and other industry such as a refinery has not been verified here. Each operator classifies its own areas. Confirm with the site operator.
