Calcium Chloride

Reliably delivering high quality calcium chloride through a network of plants and terminals.

TETRA is a global producer of a variety of calcium chloride grades. We produce premium quality calcium chloride products thanks to our proprietary manufacturing process and high-quality raw materials.

We use food grade quality hydrochloric acid and high purity limestone as raw materials to deliver calcium chloride with very low levels of alkali metals, iron, and other impurities.

Our calcium chloride is available both in solid form as white flakes and in liquid form as a transparent solution. As a solid, calcium chloride is hygroscopic (absorbs water) but also exothermic (releases heat) when it touches water. These properties allow it to be used in many technical applications. It is highly soluble and can easily be mixed with other liquids.


  • Consistent high quality calcium chloride
  • Global reach
  • Security of supply through vertical integration
  • OMRI listed; ISO 9001:2015 certified
  • Diverse range of industry-leading subject matter expertise
  • 30 years of proven track record

Our calcium chloride is used in many technical processes in diverse industries including: oil and gas; industrial; agricultural; road; and food and beverages.
