China: geography and layout
China's land-based oil resources are mostly in the north, with large fields at Daqing, Shengli, Liaohe, Karamay and Dagang, so cold-climate and arid-climate sites are both common.

ATEX and IECEx Smartphone Supplier in China
The IS-04Z1 is an intrinsically safe handset for people who cross into classified areas in China every shift: oilfield and refinery operators, coal-mining safety officers, petrochemical engineers, and the HSE and telecoms teams who equip them. Buyers searching for an ATEX and IECEx smartphone supplier for China can take the datasheet and the certification schedule for the IS-04Z1 now; supply follows certification.

Short answer. An ATEX and IECEx smartphone for China 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. Operator approval runs on its own timeline. Certification status. Place facts reviewed October 2026.

More about China that matters for portable equipment
China: rules and approvals
The current implementing rule is CNCA-C23-01:2024, in force since 1 May 2024, and certification has been to the 2021 editions of GB/T 3836 since 1 May 2022.
China: rules and approvals
GB 3836.15-2024 on design, selection and erection and GB 3836.16-2024 on inspection and maintenance took effect as mandatory national standards on 1 August 2025, governing installations rather than product certification.
China: rules and approvals
Phones also need the MIIT network access licence (NAL) and SRRC radio approval; the NAL is described as compulsory, valid for three years, with local testing and a local representative required.
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 China. In China NEPSI is the Ex certification authority, and the technical evidence behind it is typically aligned with an IECEx Certificate of Conformity, so a reviewer at Sinopec or PetroChina would ask for the NEPSI certificate first. An IECEx and ATEX dual route helps foreign contractors on petrochemical projects. All certification is in progress.

Sourcing the IS-04Z1 for China
Nothing can be bought for China 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 · China
Frequently asked questions
Can we buy an ATEX and IECEx smartphone in China 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 smartphone in China 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 China does this cover?
The market guide for China covers Shanxi, Shaanxi and Inner Mongolia, Daqing, Shengli oilfield, among others. Site-level pages are linked below.
How will SAMS supply China?
Through authorised distributors once certificates exist. Until then SAMS can send the datasheet and certification schedule and arrange safe-area evaluation units.
What climate range should devices handle in northern Chinese oilfields?
Fields such as Daqing in the north-east have cold winters, while Karamay and other north-western fields are arid, so a wide operating temperature range and dust ingress protection are sensible. Confirm site limits with the operator before deployment.
Can IECEx or ATEX certificates be used in China?
An IECEx test report is reported as recognised as test evidence, but it does not replace the CCC certificate, and ATEX certificates are not accepted. Plan a separate CCC programme with a designated body, using the IECEx test work to reduce duplication where permitted.
Is the phone suitable for underground coal mines?
The design covers Zone 1 gas and Zone 21 dust together, matching the combined methane and coal dust exposure, but certification is in progress and no certificate exists. Underground mining is a distinct classification regime, so a mine operator would need to confirm suitability. Check requirements with the mine safety authority.
