Very wet climate
Timika averages about 5,690 mm of rain a year in a tropical rainforest climate.
Grasberg held proven and probable reserves of 14.0 million tonnes of copper, 808 tonnes of gold and 3,773 tonnes of silver at the end of 2022, so mining is expected to continue for decades. Concentrate goes by 166-kilometre slurry pipeline to the port at Amamapare, so hazardous areas include fuel, power, process plant and underground workings. Distribution partners for Timika and the Grasberg mining district are being identified ahead of the Q4 2026 launch of the IS-04Z1.
Pre-launch · certification in progress · Launching Q4 2026
Short answer. Timika and the Grasberg mining district 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. A buyer's engineering review is separate from the certificate. Certification status. Place facts reviewed October 2026.

An intrinsically safe Android smartphone designed for Zone 1 and Zone 21 hazardous areas in Timika 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.
Timika averages about 5,690 mm of rain a year in a tropical rainforest climate.
Grasberg sits at about 4,100 metres elevation, and Timika's Mozes Kilangin airport handles domestic flights and interior routes.
PT Freeport Indonesia runs Grasberg, with Indonesian state interests through MIND ID holding 51.23 percent and Freeport-McMoRan 48.77 percent, and mining rights were extended to 2041.
The Grasberg mine lies in Mimika Regency, Central Papua, near Puncak Jaya, and the original mine was built at about 4,100 metres above sea level, with the open pit rim at roughly 4,270 metres.
Early construction included a 116 km road and pipeline, a port, an airstrip, a power plant and a new town, so the operation is largely self-contained and supplied by sea and air.
Mozes Kilangin Airport at Timika has direct domestic flights to Jayapura, Nabire, Sorong, Makassar and Bali, plus short flights to interior districts of Mimika such as Jila, Tsinga and Alama.
A hazardous area is a place where flammable gas, vapour or combustible dust may be present. Standards divide these into zones: Zones 0, 1 and 2 for gas and vapour, and Zones 20, 21 and 22 for dust. Zone 1 and Zone 21 are the tier where an explosive atmosphere is likely to occur in normal operation, which is where the IS-04Z1 is designed to work. Anything carried in must be marked for the zone, gas group and temperature class of the area.
No certificate has been issued for the IS-04Z1 yet, so it must not be taken into a classified area until the certificate covering it exists and the site operator has accepted it.
In Timika and the Grasberg mining district. Hazardous areas include the concentrator and process plant, fuel storage and distribution, the concentrate port and dewatering, and underground mine areas. PT Freeport Indonesia classifies them, not SAMS. The sheet does not claim methane; ask for its drawings.
A distributor for Timika and the Grasberg mining district 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 yet. The IS-04Z1 is pre-launch and its certification is still in progress ahead of a Q4 2026 launch. No unit goes into a classified area before the certificate covering it exists. The datasheet, the certification schedule and safe-area evaluation units are available now.
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.
Zone 1 and Zone 21 (gas and dust) with gas group IIC and temperature class T4, subject to certification. It must not be used in a classified area before its certificate is issued and the site has accepted it.
Likely candidates are concentrator and process plant, fuel storage and distribution, concentrate port and dewatering, underground mine 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 Timika and the Grasberg mining district.
Altitude, heavy rain, long underground haulage and remote supply make it demanding. Underground mines can have gas or dust, and surface plants have flotation chemicals, so confirm area classification with the operator and plan for battery life and spares.
The operation uses its own port at Amamapare, an airstrip and long access roads built for the mine, and Timika is the regional town. Expect long lead times, customs clearance in Indonesia and site security and induction procedures before devices go underground.
Grasberg sits at about 4,100 metres and the region is very wet, so temperature, condensation and battery behaviour matter. Check the rated operating range and sealing. IP68 is not explosion protection. Confirm site requirements with the operator.
