Background

On March 12, 2012, Thailand’s Department of Industrial Works (DIW) released the Notification on Hazard Classification and Communication System of Hazardous Substances B.E.2555 (2012) (hereinafter referred to as the Notification B.E.2555) , which is also known as Thailand GHS. The Notification B.E.2555 adopted the UN GHS Rev.3 (2009) and introduced GHS classification and communication system into Thailand in 2012. The implementation of Thailand GHS is two-step action, with GHS coming into force on March 13, 2013 for single substances and March 13, 2017 for mixtures.

Authorities and Regulations

There are six main ministries involved in GHS implementation, the Department of Industrial Works (DIW), Department of Agriculture (DOA), Department of Fisheries (DOF), Food and Drug Administration (FDA), Department of Energy Business (DOEB), Department of Livestock Development (DOLD). DIW was the first authority to start GHS implementation, FDA was the second authority, followed by the other authorities. Below are the competent authorities and major regulations.

Application Scope

Chemicals listed in the List of Hazardous Substances that are regulated by the six authorities based on the Hazardous Substance Act, including Department of Industrial Works, Department of Agriculture, Department of Fisheries, Food and Drug Administration, Department of Energy Business, Department of Livestock development.

Classification & Labeling

In line with the UN GHS Rev.3, Thailand GHS adopted 28 hazard categories covering physical hazard (16), health hazard (10) and environmental hazard (2). See the figure below.
