GHS implementation status in Mexico

      On 9 October 2015, the Ministry of Labor and Social Welfare published Mexican Official Standard NOM-018-STPS-2015 “Harmonized System for the Identification and Communication of Hazards and Risks of Hazardous Chemicals in the Workplace” (Sistema armonizado para la identificación y comunicación de peligros y riesgos por sustancias químicas peligrosas en los centros de trabajo).  This standard implements the 5th revised edition of the GHS in Mexico for the workplace. 

       The standard establishes a transitional period for implementation of three years following its publication in the Mexican Official Gazette (Diario Oficial de la Federación (DOF)). During the transitional period, employers have the choice to comply with the previous standard NOM-018-STPS-2000 (System for the Identification and Communication of Hazards and Risks of Hazardous Chemical Substances in the Workplace), or with the new one (NOM-018-STPS-2015).  With the entry into force of the new standard in October 2018, standard NOM-018-STPS-2000 (published on 27 October 2000) and amendments thereto (of 2 January 2001 and 6 September 2013) will be repealed.

       0n 3 June 2011, a national standard (NMX-R-019-SCFI-2011) based on the 3rd revised edition of the GHS was published in the Official Gazette. It may be applied as from the day following its publication (i.e. 4 June 2011). The standard establishes the criteria for the classification and labeling of chemicals and the preparation of Safety Data Sheets according to the GHS and contains 13 chapters and six annexes. Although the standard is not mandatory, it is authorized to be used as an alternate means to comply with the provisions of Chapters 7 and 8 of the mandatory standard NOM-018-STPS-2000, addressing the identification of chemical hazards and its related hazard communication at the workplace.
