Frequently asked procurement and shipping questions
Essential information regarding minimum orders, batch laboratory certification, port transit times, and customized mesh formulations.
What industrial grades of Bentonite do you supply?
We supply standard industrial bentonite grades: drilling clay for wells, binder clay for metal casting, building clay for foundations, earthing clay for grounding, and raw lumps.
Where are your manufacturing and mining operations located?
Our mines and processing factory are in Kutch, Gujarat, India. Kutch is famous for high-quality natural sodium bentonite clay that absorbs water and swells easily.
What is the Minimum Order Quantity (MOQ) for global shipments?
Our minimum order for export is 20 metric tons (one full container). We pack the clay in large 1-ton bags or standard 25kg bags.
Do you provide Certificate of Analysis (COA) and test reports?
Yes. We test every order in our lab. We send a quality test report (COA) with your shipping documents. You can also request a third-party inspection (like SGS) at the port.
Which export loading ports and shipping terms do you support?
We ship from Mundra Port and Kandla Port. It takes about 14 to 21 days to load and ship your order after it is confirmed.
Can you customize mesh sizing and packaging?
Yes. We grind the clay to different powder sizes (from coarse to very fine) and offer custom bag packaging.
