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.

Industrial Smartphone in Thailand
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. This page explains what to look for in an industrial smartphone for Thailand, and where the IS-04Z1 stands against that list today.

WhereThailand
Short answer. The SAMS IS-04Z1 is the intrinsically safe smartphone covered here for Thailand: 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. A buyer's engineering review is separate from the certificate. Certification status. Place facts reviewed October 2026.

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 · industrial
What “industrial” means for a smartphone
“Industrial” describes a phone built for plant conditions: sealed, drop-resistant and manageable at fleet scale through Android Enterprise. It does not by itself mean the phone may enter a classified area. Only a device with a valid explosion-protection certificate and marking may do that.
The IS-04Z1 is designed to be both an industrial Android phone (IP68, 4,000 mAh battery, 50 MP camera, Android 16 with EMM and MDM support) and an intrinsically safe one. Its explosion-protection certificates are in progress and have not been issued.
In Thailand. Thai fleets bring together large operators and contractors who pass a gate that safety and IT departments control. EMM and MDM support lets IT enrol and retire handsets, with a Thai-reading workforce in mind. Charging takes place in a safe area, and the battery is meant to last a long shift.
The route · specification
Specifying an industrial smartphone for Thailand
A short checklist for anyone writing or reviewing the specification, with the IS-04Z1 status against each point.
Check on the paper
- Marking
- Equipment group, category, protection concept, gas group and temperature class, matched to the area drawing.
- Certificate and schedule
- A certificate number, issuing body and the schedule of conditions, not a brochure claim.
- Standards edition
- The IEC 60079 or national standard edition the certificate was issued against.
Check for the IS-04Z1
- Marking target
- II 2 G Ex ib IIC T4: a target, not yet a certificate.
- Certificate status
- IECEx, ATEX, UKEX and NEC 500 in progress; none issued.
- Operator approval
- Separate from the certificate and handled with the site operator.
Questions · Thailand
Frequently asked questions
Can we buy an industrial smartphone 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 industrial smartphone 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 an industrial phone as well as an Ex phone?
Yes by design: IP68 sealing, a 4,000 mAh battery, a 50 MP camera and Android 16 with EMM and MDM support. The explosion-protection certificates are separate and 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.
Is intrinsically safe the same as explosion proof?
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.
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.
