Tested independently, every shipment
We are a young exporter and you have no history with us. So we do not ask you to trust our own laboratory. Every shipment is tested by an independent NABL-accredited laboratory and ships with a certificate of analysis.

XRD mineralogy report, on request
X-ray diffraction shows what minerals the clay is made of: montmorillonite, the swelling mineral that does the work, and quartz and other impurities. We use it to characterise each grade and each new mining face, at an outside laboratory, and send the report to buyers who ask. It also gives the crystalline silica figure that goes on the safety data sheet.

What arrives with every shipment
A sample certificate for an OCMA-grade lot. The real one carries the container number, the test date and the laboratory’s report number.
