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.

Industrial Cell Phone 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. If you are specifying an industrial cell phone for China, this page covers the markings, the approvals and the current certification status of the IS-04Z1.

Short answer. The SAMS IS-04Z1 is the intrinsically safe smartphone covered here for China: pre-launch, designed for Zone 1 and Zone 21 (marking target Ex ib IIC T4), with certification in progress and no certificate issued.
For the record, no certificate exists for the IS-04Z1 today. The programme is under way ahead of a Q4 2026 launch. An operator's own vendor approval is a separate step. 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 · 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 China. Large state operators run fleets in the thousands. Android 16 with EMM and MDM enrolment is built to let such an operator manage the fleet from one console, with Mandarin and English on one build. That serves local technical staff and international contractors alike. Charging stays in safe areas, not in the classified area.
The route · specification
Specifying an industrial cell phone for China
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 · China
Frequently asked questions
Can we buy an industrial cell phone in China today?
Not today. Until the certificates are issued the IS-04Z1 stays out of classified areas, and until launch there is nothing to purchase. You can ask for the datasheet and the certification schedule, or book a safe-area evaluation unit.
What does an industrial cell phone in China cost?
No price is published. While certification is in progress there is no list price and no committed lead time, and a supplier quoting a firm figure for an uncertified Ex handset is promising something it cannot stand behind. Indicative pre-launch pricing is issued in writing against a stated quantity and site.
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 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.
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.
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.
