Primary product Bentonite

Map grade to application performance

Bentonite buying should be led by function: swelling behavior, viscosity response, and moisture stability.

  • Define exact application: drilling, foundry, piling, HDD, earthing, or sealing.
  • Share process condition where rheology matters.
  • Confirm handling and storage realities at destination.

Clarify form and usage plan

Lumps and powder behave differently in handling and blending systems.

  • Choose supply form based on your dosing method.
  • Share expected monthly volume and trial target.
  • Ask for grade consistency approach for repeat shipments.

Commercial fit should follow technical fit

Quoting first and qualifying later often increases cost and delay.

  • Confirm grade shortlist before rate comparison.
  • Align packing and shipment terms to your site setup.
  • Keep documentation and dispatch updates in one owner flow.
