Thailand: logistics and access
Around 79.5% of crude oil supply is imported; domestic oil production peaked in 2016 at 486,000 barrels a day, so port, tank farm and pipeline terminals handle much of the flow.

Field notes · Thailand
More about Thailand that matters for portable equipment
Thailand: industry on the ground
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.
Thailand: infrastructure
The Erawan gas field in the Gulf of Thailand supplies about 20% of the country's gas production, which makes it an important reference point for offshore device and transport planning.
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.
The term · explosion proof
What “explosion proof” means for a smartphone
“Explosion proof” is the phrase most buyers use for equipment that may be taken into a classified hazardous area. Strictly, it covers several protection concepts: a flameproof enclosure (Ex d) contains an internal explosion, while intrinsic safety (Ex i) limits electrical energy so that an ignition cannot start. Phones are normally intrinsically safe, because a flameproof handset would be too heavy to carry all shift.
The IS-04Z1 uses intrinsic safety, with a marking target of Ex ib IIC T4, and is designed for Zone 1 and Zone 21. It is pre-launch, certification is in progress and no certificate has been issued.
In Thailand. Explosion-proof is the everyday phrase, but the Map Ta Phut crackers, reformers and tank farms hold different atmospheres. Flameproof Ex d suits fixed enclosures, while the IS-04Z1 uses intrinsic safety to limit the energy of a handheld. A reviewer asks which concept applies to a device carried across the estates.

Questions · Thailand
Frequently asked questions
Can we buy an explosion proof mobile phone in Thailand today?
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.
What does an explosion proof 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.
Is the IS-04Z1 explosion proof or intrinsically safe?
It is intrinsically safe (marking target Ex ib IIC T4), which is the usual way to make a phone for hazardous areas. It is not a flameproof (Ex d) design, and certification is still in progress.
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.
Does Thailand's heat and humidity change how I choose an intrinsically safe phone?
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.
Which part of Thailand has the most offshore hazardous-area work?
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.
Is the IS-04Z1 suited to the Rayong monsoon?
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.
