Pure for 100 years. Pure for 100 more.

ILC Resources delivered our first load of calcium carbonate in 1924. Between then and now, the purity of our products has never changed — because, today, our minerals are still nothing more than natural chemistry.

A Legacy of Service.

You can count on us to deliver every order with the same standard of service as our very first. That promise is backed by an entire team of people who take pride in our track record of dependability and transparency around the clock.

  • Sourced from calcitic limestone quarries in the U.S.

  • Third-party tested for quality, safety and consistency.

  • Delivered via dedicated nationwide distribution network.

  • Expertly crafted. Rigorously tested.

    To build on our legacy of world-class calcium carbonate, we maintain the most advanced labs in the industry for product testing. Our facilities have also received Safe Feed/Safe Food certification for going above and beyond regulatory safety standards.

  • From our quarry to your door.

    Our transportation team knows how to match quality carriers with competitive prices. In addition to our own fleet of trucks, we are a bonded broker working with qualified carriers for pneumatic bulk tanks, hoppers, vans and flatbeds.

  • Mined with the future in mind.

    Nothing goes to waste where we go to work. As the stewards of so many quarries, we’ve perfected a process that uses every part of every rock — to maximize our precious resources and minimize the impact on our planet.
