Supplier approval · Sasol
Becoming an approved supplier to 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: infrastructure
Most gasifiers at Sasolburg have been replaced by autothermal reformers fed with natural gas piped from Mozambique, which shifts feedstock handling from coal to gas pipelines and process gas.
Sasol: industry on the ground
The Sasol 1 site began commissioning in 1954, Sasol 2 was completed in 1980 and Sasol 3 came on stream in 1982, so the Secunda and Sasolburg complexes combine plant of very different ages.
Sasol: who works there
Sasol Mining operates six coal mines that supply the Secunda synfuels and Sasolburg complexes, so underground coal-mine conditions sit next to chemical plant conditions inside one company.
The term · IECEx
What “IECEx” means for a smartphone
IECEx is the international scheme for certifying equipment used in explosive atmospheres. A certificate of conformity is issued by an accredited certification body against a specific edition of the IEC 60079 standards and carries a schedule of conditions of safe use. It is not a legal requirement in most countries on its own, but many national schemes accept it as the technical basis.
The IECEx certificate for the IS-04Z1 is in progress and has not been issued. The marking target is Ex ib IIC T4, the intrinsic safety concept for Zone 1 gas with the hardest gas group (IIC) and a 135 °C temperature class.
In Sasol. Large South African complexes such as Secunda draw in international EPCs and specialist shutdown contractors, many of whom know the IECEx scheme. A reviewer should read the certificate of conformity together with its schedule of conditions. The IS-04Z1 is designed for IECEx and certification is in progress.

Questions · Sasol
Frequently asked questions
Can Sasol 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 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.
Does the IS-04Z1 hold an IECEx certificate?
No. The IECEx certificate is in progress and has not been issued. SAMS will publish the number when it exists.
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.
How will SAMS supply Sasol?
Through authorised distributors once certificates exist. Until then SAMS can send the datasheet and certification schedule and arrange safe-area evaluation units.
Do Sasol's mines and plants use the same hazardous-area rules?
Not necessarily. Underground coal mines in South Africa fall under mining safety legislation with its own approval routes, while chemical plants work to industrial classified-area practice. Confirm with Sasol Mining and with each plant which approvals and certificates it expects for portable equipment.
How does the Highveld climate affect phones used at Secunda or Sasolburg?
Both sites are on South Africa's inland Highveld, where days can be warm and winter nights cold with frost, and dust is common near mines and stockpiles. Check the device's operating temperature range, dust ingress rating and battery behaviour in cold, and ask the site about its limits.
Does the phone work in Highveld winters?
The IS-04Z1 has IP68 protection and a 4,000 mAh battery, but cold-weather battery behaviour and the permitted temperature range will come from the final certificate and datasheet. Check them for Highveld winters. IP68 is not explosion protection, and certification is still in progress.
