ATEX and IECEx Mobile Phone Supplier for CNOOC
CNOOC is a Beijing-headquartered state-owned company, established in 1982, focused on offshore oil and gas. A 2019 national science award recognised CNOOC's exploration of a deep, large-scale condensate gas field in the Bohai Bay Basin, which is a major offshore production area. This page sets out how an ATEX and IECEx mobile phone supply route to CNOOC will work for the IS-04Z1, and what is and is not available before launch.

WhereCNOOC
Short answer. An ATEX and IECEx mobile phone for CNOOC 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. An operator's own vendor approval is a separate step. Certification status. Place facts reviewed October 2026.

Supplier approval · CNOOC
How suppliers reach CNOOC
Supplier registration and equipment approval are run by the organisation itself; confirm current requirements with its procurement and HSE teams. The Ex certificate and an organisation's own vendor or engineering approval are two separate timelines; SAMS is working towards both and holds neither today.

More about CNOOC that matters for portable equipment
CNOOC: industry on the ground
The company works in six sectors: oil and gas exploration and development, technical services, logistics, chemicals and fertiliser, natural gas and power generation, and financial services.
CNOOC: geography and layout
The group's headquarters are in Beijing, in a building that opened in 2006, while production is offshore, notably in Bohai Bay and the South China Sea, far from head office.
CNOOC: who works there
CNOOC holds 7.34% of the deepwater Buzios field and 9.65% of the Mero development in Brazil, so some of its staff and contractors also work under overseas operators' rules.
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 CNOOC. A CNOOC reviewer assessing a handset for Bohai or South China Sea platforms, onshore terminals or the Huizhou complex would look for a certificate of conformity, schedule of conditions and marking. ATEX and IECEx evidence helps international partners and EPCs working with CNOOC on offshore and petrochemical projects. The IS-04Z1 is in certification and nothing has been issued.

Sourcing the IS-04Z1 for CNOOC
Nothing can be bought for CNOOC 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

Questions · CNOOC
Frequently asked questions
Can CNOOC buy the IS-04Z1 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 mobile phone for CNOOC 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.
How does CNOOC approve suppliers?
Supplier registration and equipment approval are run by the organisation itself; confirm current requirements with its procurement and HSE teams.
How will SAMS supply CNOOC?
Through authorised distributors once certificates exist. Until then SAMS can send the datasheet and certification schedule and arrange safe-area evaluation units.
What language is needed for documentation in China?
Chinese is the working language at Chinese sites, so labelling, manuals and training for hazardous-area devices are normally expected in Chinese, with English accepted for some engineering exchange. Confirm the required documentation language with CNOOC's procurement and safety departments.
How do typhoons and sea conditions affect offshore equipment planning?
Offshore facilities in the South China Sea and Bohai Bay area typically plan around seasonal storms and cold-weather periods, which restrict crew changes and logistics. For handheld devices this means robust sealing and battery planning; confirm operating rules with the platform operator.
What should be checked for typhoon-season offshore use?
Check ingress protection, battery behaviour in heat and humidity, and whether the platform's rules allow handheld devices in a given area. IP68 helps with rain and spray but is not explosion protection. The IS-04Z1 is not yet certified. Confirm conditions with the platform operator.
