Before You Order
Can I get samples before ordering?
Yes. We ship 1-5 kg of each grade by DHL or FedEx at our expense. Samples reach most international destinations in 5-7 days and each one includes a Certificate of Analysis.
What is the minimum order quantity?
One 20ft container, which is about 24 tons — roughly 20 FIBC jumbo bags. Samples of 1-5 kg per grade are available before that for laboratory evaluation.
What quality documentation comes with a shipment?
A batch-specific Certificate of Analysis covering XRF chemistry, particle size, moisture and fired whiteness at 1200 degrees C. We send it for approval before loading, and originals travel with the shipping paperwork.
Put the Theory on a Test Disc
Samples are 1-5 kg per grade, free, by courier, with the Certificate of Analysis included.
