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. An IECEx smartphone distributor in Surabaya and the Gresik industrial area would carry the IS-04Z1 to these buyers once certification completes.
Pre-launch · certification in progress · Launching Q4 2026
Short answer. Surabaya and the Gresik industrial area 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.
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.

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.
Juanda International Airport, about 12 km from central Surabaya in Sidoarjo, is Indonesia's third busiest airport and served around 500 aircraft a day in 2019, with Batik Air and Citilink using it as a hub.
Satellite cities of Mojokerto, Gresik, Sidoarjo, Bangkalan and Lamongan form the wider metropolitan area, which is where much heavier industry and port-side plants are found around the city.
The Port of Tanjung Perak in north Surabaya is Indonesia's second-busiest seaport, on a site where a modern port facility was first built in 1910, giving contractors a major sea gateway to eastern Indonesia.
The city hosts a large shipyard and several naval schools, and in the Dutch colonial era hosted the most extensive naval base in the colony, so marine and ship-repair work is a core local activity.
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 Surabaya and the Gresik industrial area. Visiting engineering firms and international customers of the Gresik fertiliser and cement works often refer to IECEx. A certificate of conformity with a schedule of conditions would be reviewed. For the IS-04Z1 these are targets, not issued, so no purchase should rely on them yet.
Distribution of the IS-04Z1 is by authorised partners only, and SAMS has not yet granted a territory for Surabaya and the Gresik industrial area. Each application is reviewed on its merits. Because opening a certified Ex handset in an ordinary workshop invalidates its certificate, the partner must be able to support and service the device locally.
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.
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.
No. The IECEx certificate is in progress and has not been issued. SAMS will publish the number when it exists.
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.
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 Surabaya and the Gresik industrial area.
Temperatures are steady, around 23 to 31 degrees, but the wet season from October to May brings heavy rain and humidity, and coastal air adds salt. Devices typically need good ingress protection and cleaning routines for exposed use.
The wider metropolitan area includes Gresik, Sidoarjo and other satellite cities with port-side and industrial plants. Typical hazards include fuel, chemical and bulk handling, so ask each operator for its zone classification and device approval requirements.
Yes in practice. Gresik lies about 25 kilometres north-west of Surabaya, and its fertiliser and cement works are major buyers of safety equipment. Requirements are set plant by plant. Confirm with each site operator's safety function.
