Large concessions
Kaltim Prima holds a 90,960-hectare concession across Sangatta and Bengalon and moves coal on a 13-kilometre conveyor to its Tanjung Bara port.
Kalimantan hosts some of Indonesia's largest open-pit coal mines, including Kaltim Prima Coal at Sangatta in East Kalimantan and Adaro's Tutupan mine in South Kalimantan. Hazardous-area work centres on fuel storage, coal handling and preparation, and mine power plants. An IECEx mobile phone distributor in Kalimantan coal mining region would carry the IS-04Z1 to these buyers once certification completes.
Pre-launch · certification in progress · Launching Q4 2026
Short answer. Kalimantan coal mining region 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.

| Standards edition | The IEC 60079 edition the certificate cites | Stated on the certificate when issued |
| Schedule of conditions | Limits of use, batteries and accessories | Published with the certificate |

An intrinsically safe Android smartphone designed for Zone 1 and Zone 21 hazardous areas in Kalimantan Mining. 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.
Kaltim Prima holds a 90,960-hectare concession across Sangatta and Bengalon and moves coal on a 13-kilometre conveyor to its Tanjung Bara port.
Tutupan produced an estimated 36 million tonnes in 2023 and Sangatta about 41 million tonnes, so fleets and workforces are large and contractor-heavy.
State utility PLN plans additional coal-fired capacity and has begun co-firing biomass at 17 power plants, so mines and power stations are linked by long coal supply chains.
The coal industry is fragmented, with a few large producers and many small firms, so equipment rules and safety culture can vary widely between neighbouring mine sites.
Coal dust is a recognised health and handling issue in Indonesian mining, so dust control, cleaning and sealed enclosures matter for electronics used around crushers, conveyors and stockpiles.
A Domestic Market Obligation requires coal miners to allocate 25 percent of production to local use at a fixed price, which shapes how much coal is railed and barged to domestic power stations.
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 Kalimantan coal mining region. Large coal operators often work with international contractors and equipment suppliers, who know IECEx. A certificate of conformity with a schedule of conditions would be reviewed. For the IS-04Z1 these are targets and not issued, so they cannot yet support specification.
SAMS is appointing authorised distributors ahead of the Q4 2026 launch. No territory has been granted for Kalimantan coal mining region 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.
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.
There is no list price yet. SAMS gives indicative pre-launch pricing in writing, against a stated quantity and site, and does not commit to a lead time before certification completes.
No. The IECEx certificate is in progress and has not been issued. SAMS will publish the number when it exists.
Likely candidates are coal handling and preparation plants (dust, zone 21), fuel and lubricant storage, mine-site power generation, coal loading terminals. 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 Kalimantan coal mining region.
Kalimantan has a tropical climate with frequent heavy rain, so devices in open-pit and barge-loading areas face water, mud and dust together. Users typically want good ingress protection and cleaning routines; check the specification against the mine's rules.
Indonesia has a Domestic Market Obligation requiring miners to allocate a share of production, 25 percent in the cited rule, to the domestic market. It affects shipping and customer mix rather than device choice, but it explains continuous coal handling at ports and power plants.
Open-pit coal sites mainly raise dust hazards at handling and preparation plants, plus gas hazards at fuel storage. The sheet does not assume methane. The operator's classification decides. Confirm with the site operator's HSE team which areas apply.
