China: rules and approvals
Explosion-protected electrical products in China need CCC certification, mandatory since 1 October 2020, to the GB/T 3836 series, which is China's adoption of IEC 60079.

More about China that matters for portable equipment
China: rules and approvals
ATEX certificates and Eurasian certificates are not accepted in China, and the applicant for CCC may be a foreign company.
China: rules and approvals
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.
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.
The term · hazardous area
What “hazardous area” means for a smartphone
A hazardous area is a place where flammable gas, vapour or combustible dust may be present. Standards divide these into zones: Zones 0, 1 and 2 for gas and vapour, and Zones 20, 21 and 22 for dust. Zone 1 and Zone 21 are the tier where an explosive atmosphere is likely to occur in normal operation, which is where the IS-04Z1 is designed to work. Anything carried in must be marked for the zone, gas group and temperature class of the area.
No certificate has been issued for the IS-04Z1 yet, so it must not be taken into a classified area until the certificate covering it exists and the site operator has accepted it.
In China. China's classified areas range from northern coal belt mines in Shanxi, Shaanxi and Inner Mongolia to inland oilfields at Daqing and Shengli and the coastal petrochemical hubs at Zhoushan, Ningbo and Maoming. Operators such as Yanzhou Coal and CNOOC classify their own areas, which SAMS does not.
The route · supply
Sourcing the IS-04Z1 for China
There is no stock to order for China 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
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 a hazardous area 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 a hazardous area smartphone 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.
Which hazardous areas is the IS-04Z1 designed for?
Zone 1 and Zone 21 (gas and dust) with gas group IIC and temperature class T4, subject to certification. It must not be used in a classified area before its certificate is issued and the site has accepted it.
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 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.
