When a manufacturer changes a formulation, how soon must the Material Safety Data Sheet (MSDS) be updated? 

If the manufacturer becomes newly aware of a hazard associated with an existing formulation, the label for that product must be revised within 3 months. For new or revised formulations, the labels and MSDS must contain new or revised hazard data when the newly formulated product is shipped. The employer must then update their MSDS directory upon receipt of the new MSDS.(1)
