Port scale
Busan handled 24.4 million TEU in 2024 and is managed by the Busan Port Authority.
Busan is South Korea's busiest port and its second most populous city, at the mouth of the Nakdong River. Shipbuilding and ship repair are key local industries, so Zone 1 conditions arise in yards, fuel and chemical storage and cargo handling. Distribution partners for Busan are being identified ahead of the Q4 2026 launch of the IS-04Z1.
Pre-launch · certification in progress · Launching Q4 2026
Short answer. Busan 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.
Status: pre-launch. IECEx, ATEX, UKEX and NEC 500 certification is in progress and no certificate has been issued; launch is planned for Q4 2026. 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 | IP65 to IP68 sealing | IP68 design |
| Drop and shock | A stated drop height onto concrete | Specification on request |
| Explosion protection | A separate certificate and marking | In progress; not issued |
| Where it applies | Busan: Fuel and chemical storage, Port cargo handling, Vessel tank spaces | Classified by the site operator |

An intrinsically safe Android smartphone designed for Zone 1 and Zone 21 hazardous areas in Busan. It is pre-launch: IECEx, ATEX and NEC 500 certification is in progress ahead of the Q4 2026 launch.
A short profile of the site and the kinds of classified area that matter for portable equipment.
Busan handled 24.4 million TEU in 2024 and is managed by the Busan Port Authority.
HJ Shipbuilding & Construction, formerly Hanjin Heavy Industries, is based at Yeongdo-gu in Busan.
The city's economy is about 76 percent services and 17 percent manufacturing, as the older manufacturing base has declined with the shift towards high-tech industry around Seoul.
Busan has South Korea's busiest port and the sixth busiest in the world, which handled 21.81 million container units in 2020, so equipment shipments can usually be arranged through frequent services.
The densest areas lie in narrow valleys between the Nakdong and Suyeong rivers, with mountains separating most districts, so industrial and port zones are spread along the coast rather than in one block.
The container terminal has 43 berths, 20 at the North Port and 23 at Busan New Port, which is described as a gateway to the Eurasian continent and a key point on the Maritime Silk Road.
A rugged phone is built to survive water, dust, drops and rough handling, usually rated by an IP code and a drop specification. Ruggedness is an environmental property: it says nothing about whether a phone may be used where flammable gas or dust is present. That is decided by explosion-protection certification and marking.
The IS-04Z1 combines both: an IP68 sealed rugged build and a design for Zone 1 and Zone 21 (marking target Ex ib IIC T4). The explosion-protection certificates are in progress and none has been issued.
In Busan. Busan is a humid subtropical port city and one of Korea's most typhoon-prone places, with salt air and heavy rain at the quayside. IP68 sealing is designed in for the IS-04Z1 and suits those conditions. It is a dust and water rating, not explosion protection, which depends on certification in progress.
SAMS is appointing authorised distributors ahead of the Q4 2026 launch. No territory has been granted for Busan 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 yet. The IS-04Z1 is pre-launch and its certification is still in progress ahead of a Q4 2026 launch. No unit goes into a classified area before the certificate covering it exists. The datasheet, the certification schedule and safe-area evaluation units are available now.
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.
It is designed to IP68 sealing, with glove-friendly controls. Ruggedness is not explosion protection: that depends on the certificates, which are in progress.
Likely candidates are vessel tank spaces, ship repair yards, fuel and chemical storage, port cargo 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 Busan.
Korean is the working language at most sites, though the port area is used to foreign crews and visitors. Plan interpreters or Korean-language safety materials for local staff, and check that device interfaces and instructions can be provided in Korean.
Port tank terminals, ship repair and shipbuilding yards, and industrial plants in the wider south-east region can all have gas or vapour areas. Each operator sets its own zones and permits, so ask for classification drawings and portable-device policy.
Busan Port Authority manages the port and the Korea Occupational Safety and Health Agency (KOSHA) covers workplace safety. SAMS does not hold any approval from either. Ask the yard or terminal which rules it applies, and confirm with the site operator.
