Port-led logistics
Tanjung Perak is the main port for eastern Java, so imported equipment normally arrives by sea.
Surabaya is the capital of East Java and home to Tanjung Perak, Indonesia's second-largest port. The Surabaya Industrial Estate Rungkut and neighbouring Gresik, with a fertiliser plant and cement works, hold the chemical, fuel and process areas where Zone 1 and Zone 21 equipment applies. If you are specifying an industrial smartphone for Surabaya and the Gresik industrial area, this page covers the markings, the approvals and the current certification status of the IS-04Z1.
Pre-launch · certification in progress · Launching Q4 2026
Short answer. The SAMS IS-04Z1 is the intrinsically safe smartphone covered here for Surabaya and the Gresik industrial area: pre-launch, designed for Zone 1 and Zone 21 (marking target Ex ib IIC T4), with certification in progress and no certificate issued.
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 | Surabaya and the Gresik industrial area: Port fuel and chemical handling, Fertiliser and chemical plants, Cement plant dust areas | Classified by the site operator |

An intrinsically safe Android smartphone designed for Zone 1 and Zone 21 hazardous areas in Surabaya. It is pre-launch: IECEx, ATEX and NEC 500 certification is in progress ahead of the Q4 2026 launch.
Who operates there and which kinds of classified area a handset would meet, from the SAMS site research.
Tanjung Perak is the main port for eastern Java, so imported equipment normally arrives by sea.
SIER was founded in 1974 and covers about 245 hectares with around 300 companies; the JIIPE estate and port in Gresik is a further 3,000-hectare development by Pelindo and AKR.
Surabaya is the capital of East Java and Indonesia's second-largest city, on the Madura Strait, and its metropolitan area of about 6,309 sq km has an estimated 10.08 million people.
Surabaya has a tropical wet and dry climate with a wet season from October to May, steady average highs near 31 degrees Celsius and lows near 23 degrees all year.
The Suramadu Bridge links Surabaya to Madura island and its completion has influenced the local economy, adding road access across the Madura Strait for industry and logistics.
A long record as a trading port has produced strong financial infrastructure, with banks, insurers and export-import companies, so procurement, customs brokerage and freight services are easy to find.
“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 Surabaya and the Gresik industrial area. Surabaya has many plants of varied size, from large operators such as Petrokimia Gresik to the estate's roughly 300 companies, so fleets range widely. MDM or EMM enrolment, contractor rules and safe-area charging should be agreed with each site.
A short checklist for anyone writing or reviewing the specification, with the IS-04Z1 status against each point.
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 port fuel and chemical handling, fertiliser and chemical plants, cement plant dust areas, industrial estate chemical plants. Which areas are classified, and to what zone, is set by the site operator's own area classification drawings.
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.
The Suramadu Bridge links Surabaya and Madura by road, and Tanjung Perak serves sea freight to eastern Indonesia. Allow time for customs clearance and for any site gate checks on electronic devices at plants and terminals.
It has Indonesia's second-busiest seaport, a large shipyard and naval facilities, plus freight forwarders and customs brokers. Marine work typically involves tank entry and hot work, so confirm each yard's permit rules for portable electronic devices.
Not necessarily. Chemical and fuel areas are gas hazards, while cement works are dust areas, and each needs a suitable marking. The IS-04Z1 target marking covers gas only. Check each area's classification with the operator.
