6. Storage: Store at cool, dry and ventilate. The shelf life is 12 months after manufacturer date. It is still available if retest result is qualified after expire date Sodium borate is a stable crystal under normal condition. If it is moistened it will react with water and release microcalorimetry.When keep in humidity condition or temperature dramatic changed environment , it may caking. Cautions in storage should keep away from the dramatic change environment, and ensure intact packing.
7. Transportation: Avoid water, exposure and violent collision .Do not transport with strong oxidizers.
