This entry covers 3 substances

9 CFR 424.21(c) names these jointly rather than separately, so Potassium chloride, magnesium chloride and calcium chloride share one row, one purpose and one permitted amount. Everything below applies to either of them, and a product using one is subject to the same figure as a product using the other.

They are not interchangeable in practice, though. The chart is a permission, not a statement that the two behave alike: which one a process uses changes how quickly the curing agent becomes available, which is why the retail cures are sold as two different blends.

Permitted uses and amounts
