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 ATEX and IECEx mobile phone supply route to Japan will work for the IS-04Z1, and what is and is not available before launch.

Short answer. An ATEX and IECEx 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.

More about Japan that matters for portable equipment
Japan: rules and approvals
As of July 2026 the Ministry of Health, Labour and Welfare lists eight registered examination bodies for this equipment, including TIIS and several bodies outside Japan.
Japan: rules and approvals
Since a January 2017 notice an IECEx test report can be submitted as the applicant's prior test results, and a certificate is valid for three years.
Japan: logistics and access
The Port of Nagoya in Ise Bay is described as Japan's largest and busiest trading port, handling about 10% of the country's trade by value, and has been run by the Nagoya Port Authority since 1951.
The term · ATEX and IECEx
What “ATEX and IECEx” means for a smartphone
ATEX is the European legal framework for equipment used in explosive atmospheres (Directive 2014/34/EU). IECEx is the international certification scheme built on the IEC 60079 standards. Buyers outside Europe often ask for both: an IECEx certificate is the technical evidence most national regimes build on, while ATEX is the legal route into the European market.
For the IS-04Z1 both routes are in progress with TÜV in Germany and neither certificate has been issued. The marking target is II 2 G Ex ib IIC T4: equipment Group II (surface industry), Category 2 (Zone 1 gas), protection concept ib (intrinsic safety), gas group IIC and temperature class T4.
In Japan. A Japanese reviewer at a coastal petrochemical complex would expect TIIS evidence, which the sheet lists as in progress, and IECEx. ATEX evidence also helps international contractors and global groups. A dual route lets one pack serve the complex's own review and visitors. No certificate has been issued.

Sourcing the IS-04Z1 for Japan
Nothing can be bought for Japan today: the IS-04Z1 is pre-launch, and SAMS will supply end users through authorised distributors once certificates exist. What a buyer can do now is take the specification, ask for the written certification schedule and arrange a safe-area evaluation, so that the right local channel contacts you 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 · Japan
Frequently asked questions
Can we buy an ATEX and IECEx 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 ATEX and IECEx 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.
Is the IS-04Z1 ATEX and IECEx certified?
Not yet. Both routes are in progress with TÜV in Germany and no certificate has been issued. Any listing that says otherwise is wrong.
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.
What radio approval does a phone need in Japan?
Radio equipment is covered by the Telec technical conformity scheme, and the certified-products database can be searched to check a model. Requirements depend on the radio technologies in the device, so confirm with a registered certification body before importing.
Can an IECEx report speed up approval in Japan?
Since 2017 an IECEx test report can be submitted as the applicant's prior test results, which can reduce testing, but the Japanese type examination certificate is still required, and it is valid for three years. Confirm the reports accepted with the chosen examination body.
Will a handset cope with typhoon-season humidity and salt air?
The IS-04Z1 has IP68 sealing, which helps with water, dust and salt-laden air. That is an ingress rating only. Ask for the datasheet's operating ranges and test a unit during a humid season round at a coastal site.
