On Feb. 9, 2021, Chile implemented GHS into its national law under Supreme Decree 57/2019 on the Classification, Labeling, and Notification of Hazardous Substances and Mixtures Regulation.  

Later, the Ministry of Health approved Resolution 777 on Aug. 23, 2021, including the official list of substance classifications, addressing the classes and hazard categories of substances, to be used as further reference for manufacturers and importers based in Chile to classify their products.

The referred list contains the chemical names, CAS numbers, classes and hazard categories, as well as specific concentration limits and multiplying (M) factors for each substance. 

If a substance is not included on the reference list, manufacturers and importers must classify their products according to the criteria established in Supreme Decree 57/19, Titles II and III, implementing GHS classification criteria.

In Chile, GHS classification will be implemented in phases, as follows:

  Industrial use Other than industrial use
Substances Feb. 9, 2022 Feb. 9, 2023
Mixtures Feb. 9, 2025 Feb. 9, 2027

UL’s experts continue to update UL’s ChemADVISOR® Regulatory Database in anticipation of the upcoming changes. The Fourth Quarterly release (2021-4) will be available in October 2021.

Recommended action items

If the company is a manufacturer or importer into Chile of any of the listed substances and/or mixtures, it must review the labels and Safety Data Sheets of their products and update their classification according to the Official List of Substance Classification.
