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

Short answer. An industrial 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.
Current position: certification in progress, nothing issued, launch targeted for Q4 2026. 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 · 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 Japan. Japanese complexes manage devices tightly, with high expectations on site engineering. The IS-04Z1 is designed for EMM or MDM enrolment, so it can be managed like the rest of the fleet. The sheet notes Japanese and English on one build. Charging belongs in safe areas.
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 industrial 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 industrial 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 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 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.
