As of October 9, chemicals in Mexico must be classified and labeled according to uniform criteria, those of GHS Revision 5.
In October 2015, the Mexican Secretariat of Labor and Social Welfare (STPS) published regulations (NOM-018-STPS-2015, only in Spanish) that gave the chemicals industry a three-year transition period, which just ended. Companies must comply with regulations at all workplaces where employees deal with hazardous chemicals.
The OECD made national implementation of GHS mandatory for all member states in July.
