Indonesia: rules and approvals
A market-access database lists CE and FCC among other schemes recognised in Indonesia, and notes that expired certificates cannot be renewed and must be tested again as a new model.
A Zone 1 and Zone 21 handset for Indonesian operators, mechanics, inspectors and contractor crews working across an archipelago where the nearest replacement device is often a flight away. If you are specifying an Ex-proof mobile phone for Indonesia, this page covers the markings, the approvals and the current certification status of the IS-04Z1.
Pre-launch · certification in progress · Launching Q4 2026
Short answer. The SAMS IS-04Z1 is the intrinsically safe smartphone covered here for Indonesia: pre-launch, designed for Zone 1 and Zone 21 (marking target Ex ib IIC T4), with certification in progress and no certificate issued.
Where things stand: the IS-04Z1 has not launched, and none of its four certification routes has produced a certificate yet. Operator approval runs on its own timeline. 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 | Indonesia: Cilacap, Central Java, Balikpapan, East Kalimantan, Dumai, Riau | Classified by the site operator |

An intrinsically safe Android smartphone designed for Zone 1 and Zone 21 hazardous areas in Indonesia. It is pre-launch: IECEx, ATEX and NEC 500 certification is in progress ahead of the Q4 2026 launch.
Operators and classified areas drawn from the SAMS Indonesia market guide.
A market-access database lists CE and FCC among other schemes recognised in Indonesia, and notes that expired certificates cannot be renewed and must be tested again as a new model.
Indonesia lies between the Indian and Pacific oceans and includes Sumatra, Java, Sulawesi and parts of Borneo and New Guinea, so field, mine and refinery sites face varied tropical conditions.
Indonesia has between 13,000 and 17,000 islands and covers 1,904,569 square kilometres, so shipping, barges and air freight are central to getting equipment to remote oil and mining sites.
Pertamina was the third-largest crude oil producer in Indonesia in 2020, behind Mobil Cepu and Chevron Pacific Indonesia, which shows that foreign-operated fields remain significant.
“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 Indonesia. An Indonesian marking check would compare gas group, temperature class and category with the zone plan at the refinery, LNG plant or field station. Hydrogen, LNG and crude service may differ, so the group needed follows the operator's classification. The IS-04Z1 marking target is II 2 G Ex ib IIC T4, and it is only a target.
A short checklist for anyone writing or reviewing the specification, with the IS-04Z1 status against each point.
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.
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.
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.

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.
SDPPI certification is compulsory for radio and telecom equipment, with local testing and a local representative required, a marking requirement and a three-year validity. Expired certificates must be tested as a new model. Confirm the current rules with SDPPI or an accredited agent before importing.
A market-access database lists CE and FCC as other recognised schemes, but also notes local testing as required for certification. Foreign reports can therefore help but may not replace testing in Indonesia, so confirm the exact approach with SDPPI or an accredited laboratory.
The market guide lists SNI, Komdigi type approval and TKDN work, together with IECEx, as in progress. None has been granted. Requirements for a given project depend on the operator and regulators, so check the current status and ask the site operator before ordering.
