Large operations such as Grasberg, at about 4,100 metres elevation, rely on long supply chains by air, road and sea.
Indonesian mining includes coal in Kalimantan, nickel in Sulawesi and the Grasberg copper-gold complex in Papua. Fuel storage, coal handling, process plants and smelters create hazardous areas, with dust areas at coal preparation and underground work at Grasberg. Distribution partners for Indonesian mining regions are being identified ahead of the Q4 2026 launch of the IS-04Z1.
Pre-launch · certification in progress · Launching Q4 2026
Short answer. Indonesian mining regions 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.
Where things stand: the IS-04Z1 has not launched, and none of its four certification routes has produced a certificate yet. 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 |
|---|---|---|
| Ex marking | Group, category, protection concept, gas group, temperature class | II 2 G Ex ib IIC T4 (target) |
| Gas group | IIA, IIB or IIC matched to the area drawing | IIC (target) |
| Temperature class | T-class below the ignition temperature of the gas | T4, 135 °C (target) |
| Where it applies | Indonesian mining regions: Underground mine areas, Smelter and process plant areas, Coal handling and preparation plants (dust, Zone 21) | 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 Indonesia Morowali Industrial Park, begun in 2013 in Central Sulawesi, is reported to be the largest nickel-based industrial area, with 11 smelters.
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.
Mining is governed by Law No. 4 of 2009 as amended by Law No. 3 of 2020, and the Directorate General of Mineral and Coal under the Energy and Mineral Resources Ministry sets policy.
“Ex-proof” is shorthand for equipment carrying an explosion-protection marking (the Ex mark) that matches the area it enters. The marking states the protection concept, gas or dust group and temperature class, and it must be backed by a certificate issued by a recognised body, so a phone described as Ex-proof should come with a certificate number you can check.
The IS-04Z1 is designed to carry the marking II 2 G Ex ib IIC T4. That is a target: certification is in progress, no certificate has been issued, and SAMS will publish the certificate numbers when they exist.
In Indonesian mining regions. A marking check on a mine would first ask whether the area is gas or dust. Coal preparation plants are dust areas, Zone 21 in the sheet, while fuel stores are gas. The IS-04Z1 target marking, II 2 G Ex ib IIC T4, covers gas only, so dust areas need separate evaluation.
A distributor for Indonesian mining regions would carry the IS-04Z1 after certification completes; the Q4 2026 launch is the planning date and no appointment has been made. SAMS reviews applicants one by one and prefers companies with their own Ex-competent technical and service staff, since certified devices must not be repaired outside approved channels.
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.
The marking target is II 2 G Ex ib IIC T4. It becomes a marking only when the certificate is issued; until then it is a design target.
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.
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 Indonesian mining regions.
Mining activity falls under the Energy and Mineral Resources Ministry, with the Directorate General of Mineral and Coal setting policy under the mining law. Equipment and radio requirements may involve other agencies, so confirm approvals with the operator and your adviser.
Many sites are in Kalimantan, Sulawesi or Papua and need sea or air freight plus long road legs. Typically contractors stock spare batteries and chargers on site, and allow longer lead times for repairs and import clearance.
The target marking, II 2 G Ex ib IIC T4, is for gas atmospheres. Coal preparation plants are dust areas, which need a dust marking and separate assessment. Do not assume coverage. Confirm requirements for each area with the mine operator's safety department.
