Chile published Decree 57, "Regulation on Classification, Labelling and Notification of Hazardous Substances and Mixtures", in the Official Journal on 9 February 2021. The regulation also implements the seventh revised edition of the Globally Harmonized System of Classification and Labelling of Chemicals (GHS 7). To facilitate compliance, Decree No.57/2019 establishes phased transition periods, setting specific deadlines based on the product type and intended use. The timelines are summarize below:

Local Adaptation of GHS 

The following GHS building blocks have not yet been adopted in Chile:

• Flammable gases: Category 1B and pyrophoric gas
• Flammable liquids, Category 4
• Desensitized explosive, all categories
• Acute toxicity (oral, dermal and inhalation), Category 5
• Skin irritation, Category 3
• Serious eye damage, Subcategory 2B
• Specific target organ toxicity (single exposure), Category 3
• Aspiration hazard, Category 2
• Aquatic acute toxicity, Category 2 and 3

GHS Labelling Requirements:

In Chile, labelling requirements are regulated under Article 245 of Decree No. 57. Labels must be provided in Spanish and must include the following elements in a clear and visible manner, in accordance with the provisions of the Decree:

• Product identifiers 
• Name, address and phone number of the national supplier
• Hazard Pictograms 
• Warning word
• Hazard statement
• Appropriate precautionary statements
• Nominal quantitiy of the substance or mixture
• Additional information

In addition, the name, address, and telephone number of the national supplier and the nominal quantity of the substance or mixture must be included on the label of the container or on the security label. 

Safety Data Sheets: 

The Safety Data Sheet (SDS) shall be compiled in accordance with the provision of Article 274 of Decree 57 and contain the 16 standard sections. It must be written in Spanish and is provided free of charge to the recipient, in paper and/or digital format, and must clearly and visibly state on each page the name of the substance or mixture as it appears on the label and the date of the updated version. The version number shall be included on the first page. Suppliers must update the SDS within a period of no more than 6 months when:

• A new information on hazard classification or new information that may affect risk management measures become available; or 
• A new restriction or prohibition is imposed in the national legislation 

GHS in Transport: 

The national transport of hazardous goods by road in Chile is regulated by Decree 40 of 21 July 2022, which makes explicit reference to the GHS and sections 3 and 5 of the UN Model Regulation on the Transport of Dangerous Goods. 

To align with these changes, Chile also updated several key national standards:
• NCh 382:2021 – Classification of Dangerous Goods (aligned with the 21st revised edition of the 
UN Model Regulations).
• NCh 2190:2019 – Labelling for Land Transport of Dangerous Goods (aligned with the 20th revised 
edition of the UN Model Regulations).
• NCh 2245:2021 – Safety Data Sheets for Chemical Products (aligned with GHS 8)
