Comparison of GHS Building Blocks in EU, USA, China and Japan

By Little Pro on 2016-08-02 Views:  Update:2017-01-18

GHS allows individual countries or competent authorities to choose which GHS hazard classes or hazard categories  to implement when GHS is incorporated into their national regulations. For example, EU has not adopted flammable liquids category 4. This approach is often called GHS Building Blocks approach. In this article, we will compare GHS building blocks adopted in EU, USA, China and Japan.

Comparison of GHS Building Blocks

This comparison is made on 2 August 2016 based on the following GHS regulations and standards. The equivalent GHS version has also been given.

  • UN GHS Purple Book (2015) - GHS Rev. 6;
  • EU CLP Regulation (latest amendment in 2016) - GHS Rev. 5;
  • USA OSHA Hazard Communication Standard (2012) - GHS Rev. 3;
  • China GB 30000 Classification and Labelling of Chemicals (2013) - GHS Rev. 4;
  • Japan JIS 7252 Classification of Chemicals Based on GHS (2014) - GHS Rev.4;

It should be noted that there are additional hazard categories for simple asphyxiants and combustible dust in the US. In Europe, there are also some supplementary hazard classes which are not included in the GHS.
