Chemicals on the list of hazardous substances that are regulated by different authorities.

Thailand adopted GHS in 2012 for the purpose of hazard communication for chemicals by promulgating the ministerial notification B.E. 2555 (2012). The implementation of GHS is two-step action, with GHS taking effective on Mar 13, 2013 for single substances and Mar 13, 2017 for mixtures.

· The ministerial notification B.E.2555 (2012) on GHS is promulgated by the DIW under the Hazardous Substance Act

· in compliance with 3rd revision of UN GHS

· currently only applicable for chemicals under the scope of DIW and FDA

DIW is the first authority to enforce GHS, followed by FDA.

GHS implementation progress countrywide

DIW is the first authority to implement GHS on chemicals used for industrial purpose. FDA also has required the manufactures and importers follow the GHS rules on hazard classification, labels and SDS when notifying the chemical substances. Other authorities such as DOLD will soon follow the suit. GHS committee will be established to guarantee the consistency in GHS implementation countrywide.
