NS-SALT™ Calcium Chloride Flakes are white, free-flowing flakes that meet or exceed ASTM D98 and AASHTO M144 purity requirements for Type S, Grade 3, Class B calcium chloride. With a minimum of 83% active ingredient (calcium chloride), it is 10% higher than conventional 77-80% calcium chloride flake. 

This purified inorganic salt is produced by removing water from a naturally occurring brine solution. The National Organic Standards Board classified the brine process as “non-synthetic” since it does not involve reactions with chemicals such as hydrochloric acid or ammonia.
