Quality
Measured, inspected, documented.
A specification is only worth what can be proven at the loading port. These are the checks every shipment passes through.
Third-party inspection at loading
Independent surveyors such as SGS sample and verify the material at the loading point. Their certificates of quality and quantity travel with the shipping documents.
Particle size by laser diffraction
Micronized grades are analysed on Malvern laser-diffraction equipment at a university central research laboratory. You receive the full distribution — d10, d50, d90 — not a marketing figure.
Technical data sheet for every grade
Each LS code has a technical data sheet covering purity, moisture, ash, acidity, particle size and contaminant limits, issued with the lot.
