Transport and storage

Sodium chloride should be transported in clean, indoor means of transport, in accordance with applicable law. The load should be evenly distributed in a manner preventing movement of packages and their mutual damage.

Note: Salt is a hygroscopic substance; product should be protected against moisture and/or from getting wet! C

The product should be stored in clean and dry place with humidity below 75% in tightly closed containers.
During storage and transport of sodium chloride with potassium ferrocyanide content (anticaking agent) below 3 mg/kg is lumpy.
