Thailand: logistics and access
Gas supply is topped up with LNG imports and pipeline gas from Myanmar (6.2 and 7.8 billion cubic metres respectively in 2018), so LNG regasification and receiving stations are part of the hazardous-area picture.
A Zone 1 and Zone 21 handset for the people inside the Thai petrochemical cluster: shift operators on the Map Ta Phut crackers, reliability engineers at Sriracha, jetty and tank farm crews along the Rayong coast, and the safety and IT departments that rule on what passes a gate. Map Ta Phut in Rayong, opened in 1990 and run by the Industrial Estate Authority of Thailand, is the largest industrial estate in the country, with 151 factories including petrochemical plants and refineries across about 166 square kilometres. An IECEx mobile phone distributor in Thailand would carry the IS-04Z1 to these buyers once certification completes.
Pre-launch · certification in progress · Launching Q4 2026
Short answer. Thailand 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.
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.

An intrinsically safe Android smartphone designed for Zone 1 and Zone 21 hazardous areas in Thailand. It is pre-launch: IECEx, ATEX and NEC 500 certification is in progress ahead of the Q4 2026 launch.
The main operators, industrial areas and sites that the SAMS Thailand market guide covers.
Gas supply is topped up with LNG imports and pipeline gas from Myanmar (6.2 and 7.8 billion cubic metres respectively in 2018), so LNG regasification and receiving stations are part of the hazardous-area picture.
Natural gas makes up about 27% of Thailand's total energy supply and fuels roughly 64% of electricity generation, so gas processing, pipelines and power plants dominate classified-area work.
The transport sector uses nearly half of oil products and oil is 41% of total energy supply, so fuel depots, filling terminals and distribution sites occur across the whole country.
As of March 2024 Thailand had 34 active petroleum projects across 47 oil fields in the Gulf of Thailand, so offshore platform and supply-base work is a large part of upstream activity.
IECEx is the international scheme for certifying equipment used in explosive atmospheres. A certificate of conformity is issued by an accredited certification body against a specific edition of the IEC 60079 standards and carries a schedule of conditions of safe use. It is not a legal requirement in most countries on its own, but many national schemes accept it as the technical basis.
The IECEx certificate for the IS-04Z1 is in progress and has not been issued. The marking target is Ex ib IIC T4, the intrinsic safety concept for Zone 1 gas with the hardest gas group (IIC) and a 135 °C temperature class.
In Thailand. IECEx is the scheme most visiting contractors and international owners at Map Ta Phut and Sriracha are likely to know, including ExxonMobil and PTTEP offshore. A certificate of conformity with its schedule of conditions gives them a common reference beside the Thai approval route. The IS-04Z1 IECEx certification is in progress.
A distributor for Thailand 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.
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.
No. The IECEx certificate is in progress and has not been issued. SAMS will publish the number when it exists.

Yes, because tropical heat and humidity put stress on batteries and seals. Check the maximum ambient rating on the certificate, the water and dust ingress rating and how the device behaves in direct sun. Spare batteries are typically worthwhile on long outdoor shifts.
The Gulf of Thailand, with 34 active petroleum projects across 47 fields as of March 2024, including the Erawan field. Crew change and supply bases on the coast also hold classified areas. Confirm each platform's rules with its operator and helicopter or boat provider.
IP68 sealing and a rugged build are the design floor for heavy rain on open pipe racks and humid heat. The certificate ambient range is the compliance figure and is still in progress. Test a unit in the wet season and confirm the range with the site.
