Intrinsically Safe Mobile Phone Supplier in Japan
The IS-04Z1 is an intrinsically safe handset for people who cross into classified areas in Japan every shift: refinery and petrochemical-complex operators, LNG terminal crews, inspection engineers, and the HSE and telecoms teams who equip them. This page sets out how an intrinsically safe mobile phone supply route to Japan will work for the IS-04Z1, and what is and is not available before launch.

Short answer. An intrinsically safe mobile phone for Japan cannot be bought yet: the SAMS IS-04Z1 is pre-launch (certification in progress, no certificate issued), and the datasheet, certification schedule and safe-area evaluation units are available now.
Where things stand: the IS-04Z1 has not launched, and none of its four certification routes has produced a certificate yet. An operator's own vendor approval is a separate step. Certification status. Place facts reviewed October 2026.

Field notes · Japan
More about Japan that matters for portable equipment
Japan: infrastructure
Small rivers, including the Edo River, supply water to the Keiyo industrial region, and the Port of Chiba serves the zone.
Japan: rules and approvals
Explosion-protected electrical equipment must pass type examination, called kentei, under Article 44-2 of the Industrial Safety and Health Act, and equipment without the pass mark may not be used.
Japan: rules and approvals
The type examination involves a sample for structural inspection, with no factory audit in law, and the applicant can be a Japanese or foreign manufacturer or an importer.
The term · intrinsically safe
What “intrinsically safe” means for a smartphone
Intrinsic safety limits the electrical and thermal energy in a circuit so that neither a spark nor a hot surface can ignite a gas or dust atmosphere, even when a fault occurs. The ib level, used for Zone 1, tolerates one fault. It is the usual way to make a handheld device that a worker carries continuously through a hazardous area.
The IS-04Z1 is designed on this principle for Zone 1 and Zone 21 (marking target II 2 G Ex ib IIC T4). Intrinsic safety is a design basis, not a certificate: certification is in progress and none has been issued yet.
In Japan. Operators, inspection engineers and LNG terminal crews at large integrated complexes cover long rounds that cross zones repeatedly. An intrinsically safe handheld lets them record checks and photograph findings at the point of work. That is the design intent, pending certification and the site's own approval.
The route · supply
Sourcing the IS-04Z1 for Japan
There is no stock to order for Japan yet. The IS-04Z1 is pre-launch, certification is in progress, and supply will run through authorised distributors after the certificates are issued. Procurement teams can prepare now with the datasheet, the certification schedule and a safe-area evaluation.
- 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

Questions · Japan
Frequently asked questions
Can we buy an intrinsically safe mobile phone in Japan 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 intrinsically safe mobile phone in Japan 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.
What does ‘intrinsically safe’ mean for the IS-04Z1?
The circuits are designed to limit energy so a spark or hot surface cannot ignite a gas or dust atmosphere, even with one fault (level ib, Zone 1). Certification of that design is in progress.
Which sites in Japan does this cover?
The market guide for Japan covers Kashima, Mizushima, Chiba / Sodegaura, Yokkaichi, among others. Site-level pages are linked below.
How will SAMS supply Japan?
Through authorised distributors once certificates exist. Until then SAMS can send the datasheet and certification schedule and arrange safe-area evaluation units.
Is Japanese type examination required for Ex phones?
Explosion-protected electrical equipment must pass type examination under Article 44-2 of the Industrial Safety and Health Act, and equipment without the pass mark may not be used. Registered examination bodies, including some outside Japan, carry it out. Check the current process with one of them.
Where do hazardous-area sites sit in Japan?
Typically in coastal industrial zones such as the Keiyo zone along Tokyo Bay, which has refineries and chemical plants, and similar bayside complexes elsewhere. The operator issues the area classification, so request the zone drawing, gas group and temperature class before selecting equipment.
Is TIIS required for use in Japan?
The market guide lists TIIS and IECEx as in progress and neither has been granted. Whether a given site needs TIIS depends on the operator and the regulations it follows. Ask the site operator and check the current certification status before ordering.
