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.

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: 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.
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Most gasifiers at Sasolburg have been replaced by autothermal reformers fed with natural gas piped from Mozambique, which shifts feedstock handling from coal to gas pipelines and process gas.
The term · explosion proof
What “explosion proof” means for a smartphone
“Explosion proof” is the phrase most buyers use for equipment that may be taken into a classified hazardous area. Strictly, it covers several protection concepts: a flameproof enclosure (Ex d) contains an internal explosion, while intrinsic safety (Ex i) limits electrical energy so that an ignition cannot start. Phones are normally intrinsically safe, because a flameproof handset would be too heavy to carry all shift.
The IS-04Z1 uses intrinsic safety, with a marking target of Ex ib IIC T4, and is designed for Zone 1 and Zone 21. It is pre-launch, certification is in progress and no certificate has been issued.
In Sasol. Synthetic fuels, chemical plants and refinery units show that explosion-proof is shorthand for several concepts. Flameproof Ex d covers fixed motors and enclosures, and intrinsic safety suits handhelds. A phone relies on the second. The IS-04Z1 target marking is II 2 G Ex ib IIC T4, subject to certification.

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 explosion proof mobile phone for Sasol 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.
Is the IS-04Z1 explosion proof or intrinsically safe?
It is intrinsically safe (marking target Ex ib IIC T4), which is the usual way to make a phone for hazardous areas. It is not a flameproof (Ex d) design, and certification is still in progress.
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.
