China: background
The Daqing field in Heilongjiang, discovered in 1959 in the Songhua Jiang-Liao basin, has been the backbone of Chinese oil production for decades, and Shengli began producing in 1968.

Industrial Cell Phone Distributor 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. CNCA designated six certification bodies and 13 testing laboratories for Ex products, and an IECEx test report may serve as test evidence but does not replace the CCC certificate. An industrial cell phone distributor in China would carry the IS-04Z1 to these buyers once certification completes.

WhereChina
Short answer. China has no appointed SAMS distributor yet: the IS-04Z1 is pre-launch (certification in progress, no certificate issued, launch planned for Q4 2026), and distributor applications are open.
Where things stand: the IS-04Z1 has not launched, and none of its four certification routes has produced a certificate yet. A buyer's engineering review is separate from the certificate. Certification status. Place facts reviewed October 2026.

Field notes · China
More about China that matters for portable equipment
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.
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.
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 · distribution
Distributing the IS-04Z1 in China
Distribution of the IS-04Z1 is by authorised partners only, and SAMS has not yet granted a territory for China. Each application is reviewed on its merits. Because opening a certified Ex handset in an ordinary workshop invalidates its certificate, the partner must be able to support and service the device locally.
What SAMS looks for in a partner
- Operator relationships
- Existing supplier registrations or a clear route to them with the main operators and contractors in China.
- Ex-competent staff
- People who understand zone classification, markings and the conditions of a certificate.
And equally important
- Local-language support
- Documentation, training and helpdesk in the languages the workforce uses.
- Service capability
- Spares, battery replacement and repair routed through SAMS-approved channels.
Questions · China
Frequently asked questions
Can we buy an industrial cell phone in China today?
No. Nothing can be bought or taken into a classified area today: certification is in progress and launch is planned for Q4 2026. What is available now is the datasheet, the written certification schedule and evaluation units for safe-area use.
What does an industrial cell phone 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 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.
How do I become a SAMS distributor for China?
Apply through the distributor page with your company details and the territory you cover. SAMS reviews applications company by company and has not yet granted a territory for China.
What radio and network approvals does a smartphone need in China?
In addition to CCC where applicable, radio devices need SRRC approval and phones connecting to public networks need the MIIT network access licence. The NAL is described as compulsory, valid for three years, with local testing and a local representative. Confirm the current requirements with MIIT or an accredited body.
Do Ex phones need a CCC mark in China?
Products that fall within the explosion-protected electrical category of the CCC catalogue may not be sold, imported or used in business without a CCC certificate and mark, to the GB/T 3836 series. Check with a CNCA-designated body whether a given product falls within that catalogue scope.
Does NEPSI certification mean a Chinese operator will accept the phone?
No: Sinopec, PetroChina and the major coal producers each run their own equipment-approval and procurement process, so a device can be NEPSI-certified and still unlisted. NEPSI and SRRC are being pursued and are not finished. Confirm the listing route with the operator.
