Supplier approval · Sasol
Supplier registration at Sasol
Sasol runs supplier applications through the Supplier Information Management (SIM) module on Ariba for suppliers working with it in South Africa and Mozambique; confirm current requirements with Sasol Supplier Management. 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.
Field notes · Sasol
More about Sasol that matters for portable equipment
Sasol: geography and layout
The company is headquartered in Sandton, with its main plants at Secunda and Sasolburg and retail garages around Johannesburg, so site contacts may sit in different places from head office.
Sasol: background
Sasol was formed in 1950 at Sasolburg around coal liquefaction, and today it develops synthetic fuel technologies and produces liquid fuels, chemicals, coal tar and electricity.
Sasol: industry on the ground
Beyond fuels, Sasol sells over 200 chemical products worldwide, including ammonia-based fertilizers and explosives, which adds dust, ammonia and solvent hazards to the plant mix.
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 Sasol. A Sasol reviewer at Secunda or Sasolburg would expect certificate evidence naming the model, marking and area, given the range of synthetic fuel, chemical and gas plants. International contractors on shutdown work may carry ATEX or IECEx papers, so a dual route helps. The IS-04Z1 programme is in progress.

Questions · Sasol
Frequently asked questions
Can Sasol buy the IS-04Z1 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 ATEX and IECEx mobile phone for Sasol 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 Sasol approve suppliers?
Sasol runs supplier applications through the Supplier Information Management (SIM) module on Ariba for suppliers working with it in South Africa and Mozambique; confirm current requirements with Sasol Supplier Management.
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.
Is Sasol a good target for a new supplier of Ex-rated devices?
Sasol is a large multi-site buyer, but supplier approval is run by the company and its units. Typically a new supplier needs to register, pass technical and HSE review and often start with a pilot. Confirm the current route with Sasol's procurement and the relevant site engineering group.
Which Sasol areas are most likely to need intrinsically safe handhelds?
Typical candidates are gas and liquid process units, tank farms and loading areas at Secunda and Sasolburg, plus underground coal mines where methane and coal dust create their own classification rules. Zoning is decided per installation, so ask each site's HSE team for classification drawings.
How do suppliers apply to work with Sasol?
The sheet says Sasol runs supplier applications through the Supplier Information Management (SIM) module on Ariba, for suppliers working with it in South Africa and Mozambique. Confirm current requirements with Sasol Supplier Management. The IS-04Z1 is pre-launch and has no certificate.
