Asbestos-free talc.
Independent assessment.
Source-specific laboratory evidence supports material qualification. We discuss the laboratory, sampling plan and analytical scope around your requirements.
Talc and asbestos: different minerals
Talc and asbestos are different mineral materials, but they can occur near one another in some geological settings. Source selection and suitable testing are therefore important. Colour, brightness, hand sorting or a country-of-origin label cannot establish the absence of asbestos.
Asbestos is a known inhalation carcinogen. An asbestos result addresses one part of material qualification; it is not a general declaration that a powder is harmless. Review the applicable safety data and dust-control requirements for handling.

How to read an asbestos report
| Requirement | What to specify or check |
|---|---|
| Sample identity | Does the sample reference connect to the source, grade and lot being offered? |
| Sampling | Who collected the sample, from what material and with what coverage? |
| Methods | Check the actual analytical methods and preparation. PLM and TEM are microscopy approaches; XRD provides mineral-phase information and should not be treated as an interchangeable trace-fibre test. |
| Results and limits | Read reported findings, reporting limits and qualifications. “Not detected” is a result within that test’s scope, not proof of absolute zero everywhere in a deposit. |
| Laboratory and date | Review laboratory competence, report date and whether the sample remains relevant to the current supply. |
| Follow-up | Agree additional sampling or assessment when the source, material or buyer requirement changes. |

The right laboratory.
The agreed test scope.
Laboratory selection can include SGS in the Netherlands, RJ Lee Group in the USA and other suitably qualified laboratories, according to the material, assessment and documentation required.
Discuss your preferred laboratory and qualification requirements with our team. The agreed assessment should identify the source, grade and sample, together with the analytical methods and reporting limits.

Other qualified laboratories
Laboratory selection is agreed around the buyer’s qualification requirements.
No detectable asbestos
in the samples tested.
Our Sherwan technical documentation summarises a no-detect result for samples assessed by RJ Lee Group using X-ray diffraction (XRD), polarised light microscopy (PLM) and transmission electron microscopy (TEM).
The supporting laboratory report defines the sample identities, methods, results and reporting limits. Naming a laboratory does not extend a result to material it has not assessed.

Pakistan and Afghan talc
Each origin and selected grade needs relevant supporting evidence. The documented Sherwan result concerns Pakistan-origin samples; Afghan talc is evaluated with its own source-specific documentation.
