Nickel hubs
The Indonesia Morowali Industrial Park, begun in 2013 in Central Sulawesi, is reported to be the largest nickel-based industrial area, with 11 smelters.
Indonesian mining includes coal in Kalimantan, nickel in Sulawesi and the Grasberg copper-gold complex in Papua. The Indonesia Morowali Industrial Park in Central Sulawesi, the country's largest nickel processing site, covers 2,000 hectares and is served by its own seaport, an airport and a 2 GW coal power plant. This page explains what to look for in an explosion proof mobile phone for Indonesian mining regions, and where the IS-04Z1 stands against that list today.
Pre-launch · certification in progress · Launching Q4 2026
Short answer. The SAMS IS-04Z1 is the intrinsically safe smartphone covered here for Indonesian mining regions: pre-launch, designed for Zone 1 and Zone 21 (marking target Ex ib IIC T4), with certification in progress and no certificate issued.
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. A buyer's engineering review is separate from the certificate. Certification status. Place facts reviewed October 2026.
| Check | What to look for | IS-04Z1 today |
|---|---|---|
| Protection concept | Flameproof (Ex d) or intrinsic safety (Ex i) | Intrinsic safety, level ib |
| Zone suitability | Zone 1 gas and Zone 21 dust | Design target for Zone 1 and 21 |
| Certificate | Number, issuing body and schedule of conditions | In progress; not issued |
| Where it applies | Indonesian mining regions: Coal handling and preparation plants (dust, Zone 21), Fuel and lubricant storage, Underground mine areas | Classified by the site operator |

An intrinsically safe Android smartphone designed for Zone 1 and Zone 21 hazardous areas in Indonesia Mining. It is pre-launch: IECEx, ATEX and NEC 500 certification is in progress ahead of the Q4 2026 launch.
The companies on site and the hazardous-area types a handset is likely to meet there.
The Indonesia Morowali Industrial Park, begun in 2013 in Central Sulawesi, is reported to be the largest nickel-based industrial area, with 11 smelters.
Hot, wet tropical conditions at lowland sites; cooler and very wet in the Papua highlands.
In 2024 Indonesia was estimated to be the world's leading producer of mined nickel at 62 percent of global output, and second for tin at 19 percent and cobalt at 12 percent.
Indonesia holds the world's largest nickel reserves, estimated at 55 million tonnes, and its share of global nickel output rose from 16 percent in 2017 to 54 percent in 2023.
MIND ID is the state-owned mining holding company, and foreign-owned or partly foreign-owned operators include PT Freeport Indonesia, PT Tsingshan Steel Indonesia, PT Huafei Nickel Cobalt and PT Vale Indonesia.
Nickel laterite is processed in Indonesia by methods including high-pressure acid leaching, which brings pressurised acid and chemical handling areas into mine-site processing plants.
“Explosion proof” is the phrase most buyers use for equipment that may be taken into a classified hazardous area. Strictly, it covers several protection concepts: a flameproof enclosure (Ex d) contains an internal explosion, while intrinsic safety (Ex i) limits electrical energy so that an ignition cannot start. Phones are normally intrinsically safe, because a flameproof handset would be too heavy to carry all shift.
The IS-04Z1 uses intrinsic safety, with a marking target of Ex ib IIC T4, and is designed for Zone 1 and Zone 21. It is pre-launch, certification is in progress and no certificate has been issued.
In Indonesian mining regions. Mining blends hazard types. Coal preparation plants have combustible dust, fuel stores have flammable vapour, and underground work at Grasberg has its own rules. Explosion-proof is a loose term across these. Intrinsic safety suits a handheld carried between areas, while dust zones need a dust-suitable marking.
A short checklist for anyone writing or reviewing the specification, with the IS-04Z1 status against each point.
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.
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 intrinsically safe (marking target Ex ib IIC T4), which is the usual way to make a phone for hazardous areas. It is not a flameproof (Ex d) design, and certification is still in progress.
Likely candidates are coal handling and preparation plants (dust, zone 21), fuel and lubricant storage, underground mine areas, smelter and process plant areas. 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.
Typical examples are underground methane or coal-dust zones, fuel storage and workshops, explosives magazines, smelter and processing areas with gases or dust, and captive power plants. Each operator classifies its own site, so confirm the zones with the mine's safety department.
Yes. Smelters and acid-leach plants emphasise process gases, chemicals and high temperatures, while coal mines emphasise methane and combustible dust. The device choice and the area type differ, so ask each site for its classification and permit rules.
Remote operations rely on long supply chains, so a failed device may take time to replace. Plan spares, local service access and offline-capable apps. Check heat, wet and altitude conditions at each site. Confirm site rules with the operator.
