As of June 1, 2015 all U.S. chemical manufacturers are required to be in compliance with the International SDS and GHS standards. This final rule modifies the HCS and aligns it with the Globally Harmonized System of Classification and Labelling that has been established by the U.N. OSHA determined the modifications are necessary to reduce cost and burdens while improving the quality and consistency of the information provided to both employers and employees in regards to chemical hazards.
