Global Harmonization

The HCS 2012 is now aligned with the United Nations Globally Harmonized System of Classification and Labeling of Chemicals (GHS) that provides many benefits, including:

• Providing a common and coherent approach to classifying chemicals and communicating hazard information on labels and safety data sheets

• Improving the quality and consistency of hazard information in the workplace

• Helping reduce trade barriers

• Productivity improvements for businesses that regularly handle, store, and use classified hazardous chemicals;

• Providing cost savings for businesses that periodically update safety data sheets and labels for classified chemicals.
