About Khattco International
An Australian company supplying calcium carbonate mined and processed in Pakistan to industrial buyers worldwide.
Who we are
The company behind the shipment.
Khattco International is an Australian company that supplies ground calcium carbonate to industrial buyers around the world. The mineral is mined and processed in Pakistan.
That link between Australia and Pakistan is how we work. We deal with producers at source, and we serve buyers in every region, so a procurement team has one company to talk to.

Why Pakistan
Why Pakistani calcium carbonate.
Four reasons industrial buyers look to Pakistan for limestone and marble.
- 01
High purity
Pakistan has deposits of limestone and marble with a high calcium carbonate content. Purity matters most where the powder goes into paint, paper and plastics.
- 02
Natural whiteness
Much of the stone is naturally white. A white starting material means a bright powder, which buyers look for in coatings, paper and polymers.
- 03
Large reserves
The deposits are large, which supports steady supply over the long term rather than a one off purchase.
- 04
Competitive cost
Quarrying and processing costs in Pakistan let us quote competitively against other origins.
