Thailand: industry on the ground
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.

Field notes · Thailand
More about Thailand that matters for portable equipment
Thailand: industry on the ground
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.
Thailand: geography and layout
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.
Thailand: projects and investment
The Eastern Economic Corridor, set up in 2017, spans three eastern provinces covering 13,266 square kilometres, and follows the earlier Eastern Seaboard programme that financed ports, roads, waterworks and industrial parks.
The term · hazardous area
What “hazardous area” means for a smartphone
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 Thailand. Thai classified areas cluster in one corridor: Map Ta Phut Industrial Estate, the Rayong estates, Sriracha in Chonburi and the wider EEC, with offshore platforms in the Gulf and older plants along the Chao Phraya. The operator classifies each area. SAMS does not classify any area.
The route · supply
Sourcing the IS-04Z1 for Thailand
Supply of the IS-04Z1 to Thailand starts only after certification, through authorised distributors. Until then a buyer can request the datasheet and the written certification schedule, and arrange a safe-area evaluation unit, which puts the site on the list for the right local channel at launch.
- 01
Request the datasheet
The technical specification, marking target and conditions of use, sent by email.
- 02
Ask for the certification schedule
Which certificates are in progress, in what order, and what is still to be confirmed.
- 03
Evaluate in a safe area
Evaluation units can be used for connectivity, MDM enrolment and workflow testing outside classified areas.
- 04
Register for launch
Tell us the site, zone, gas group and quantity so the right authorised distributor can contact you.
Questions · Thailand
Frequently asked questions
Can we buy a hazardous area mobile phone in Thailand today?
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.
What does a hazardous area mobile phone in Thailand cost?
There is no list price yet. SAMS gives indicative pre-launch pricing in writing, against a stated quantity and site, and does not commit to a lead time before certification completes.
Which hazardous areas is the IS-04Z1 designed for?
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.
Which sites in Thailand does this cover?
The market guide for Thailand covers Map Ta Phut Industrial Estate, Rayong industrial estates, Sriracha, Chonburi, Laem Chabang, among others. Site-level pages are linked below.
How will SAMS supply Thailand?
Through authorised distributors once certificates exist. Until then SAMS can send the datasheet and certification schedule and arrange safe-area evaluation units.
Do Thai plants usually accept IECEx or ATEX certified devices?
Many operators, particularly those with international ownership, work to IEC 60079 and accept IECEx or ATEX paperwork, but this is decided by each site's own safety procedure. Ask for the approved equipment list and supply the certificate and marking details with your request.
What gas-related facilities in Thailand typically need Zone 1 devices?
Gas processing plants, pipeline stations, LNG receiving terminals, power stations using gas and offshore platforms are typical examples, given that gas fuels about 64% of electricity. Zone classification is site specific, so request the hazardous-area layout drawings.
What approvals are involved for use in Thailand?
The sheet describes certification under way with IECEx, the TISI and the NBTC route. None has been issued yet. A buyer should ask for the schedule and check the final certificates against site and regulator requirements before use.
