Cross-border access
The Johor-Singapore Causeway links the city to Singapore, so supply and specialist services often move between the two.
Johor Bahru is the state capital of Johor at the southern tip of Peninsular Malaysia, next to Singapore. Johor Bahru has an equatorial climate with steady temperatures, daily averages between about 26 and 28 degrees Celsius, high humidity all year, around 2,350 mm of rain a year and no cyclones. Distribution partners for Johor Bahru and Pasir Gudang are being identified ahead of the Q4 2026 launch of the IS-04Z1.
Pre-launch · certification in progress · Launching Q4 2026
Short answer. Johor Bahru and Pasir Gudang 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.
For the record, no certificate exists for the IS-04Z1 today. The programme is under way ahead of a Q4 2026 launch. Operator approval runs on its own timeline. Certification status. Place facts reviewed October 2026.

An intrinsically safe Android smartphone designed for Zone 1 and Zone 21 hazardous areas in Johor Bahru. 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.
The Johor-Singapore Causeway links the city to Singapore, so supply and specialist services often move between the two.
Hot and humid all year with about 2,350 mm of annual rain, concentrated in the monsoon periods.
The city forms Zone A of Iskandar Malaysia, the country's largest special economic zone by investment value, and is part of the Johor-Singapore Special Economic Zone and the Indonesia-Malaysia-Singapore Growth Triangle.
Local industries include plastic manufacturing, electrical and electronics and food processing, so the city is a base for factory and warehouse work, while the heavy petrochemical sites lie further out in Johor.
Rail from the city to Woodlands in Singapore was built in the 1880s and 1890s, the Peninsula railway extension finished in 1909, and the Causeway opened in 1923, so cross-border links are long established.
The Pengerang Integrated Petroleum Complex, in the Pengerang municipality of Johor, is described as the largest petrochemical complex in Malaysia and a major petrochemical hub internationally.
ATEX is the European legal framework for equipment used in explosive atmospheres (Directive 2014/34/EU). IECEx is the international certification scheme built on the IEC 60079 standards. Buyers outside Europe often ask for both: an IECEx certificate is the technical evidence most national regimes build on, while ATEX is the legal route into the European market.
For the IS-04Z1 both routes are in progress with TÜV in Germany and neither certificate has been issued. The marking target is II 2 G Ex ib IIC T4: equipment Group II (surface industry), Category 2 (Zone 1 gas), protection concept ib (intrinsic safety), gas group IIC and temperature class T4.
In Johor Bahru and Pasir Gudang. Johor's heavy industry sits at Pasir Gudang and Pengerang, where international contractors and EPCs often arrive with European and international documentation. A reviewer there would look for ATEX and IECEx evidence side by side for a handheld, and a dual route reduces duplicated paperwork. IS-04Z1 certification is in progress and no certificate has been issued.
SAMS is appointing authorised distributors ahead of the Q4 2026 launch. No territory has been granted for Johor Bahru and Pasir Gudang 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.
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.
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.
Not yet. Both routes are in progress with TÜV in Germany and no certificate has been issued. Any listing that says otherwise is wrong.
Likely candidates are port liquid bulk terminals, petrochemical and oleochemical plants, refinery and petrochemical process units (pengerang), fuel and chemical storage. 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 Johor Bahru and Pasir Gudang.
An equatorial climate with high humidity, around 2,350 mm of rain a year and steady warm temperatures means moisture ingress and condensation are the main concerns. Devices typically need good sealing and cleaning routines, subject to the plant's rules.
Its position beside Singapore, the Iskandar special economic zone and the Causeway make cross-border supply practical, though customs procedures and border queues apply. Confirm duty treatment, radio type approval and site gate requirements with your freight agent.
No. Pasir Gudang is an industrial estate with a port and many plants, while Pengerang is a separate complex east of Johor Bahru. Each operator sets its own procurement, HSE and classification rules, so ask the specific plant for its requirements.
