After months of public consultation, Peru's Ministry of the Environment (MINAM) has formally approved the Regulation of Legislative Decree N° 1570, the Law on the Integral Management of Chemical Substances, publishing it in the Official Gazette El Peruano on 8 April 2026.  This decree aims to protect human health and the environment by regulating the life cycle of chemical substances, with an emphasis on the classification, labelling, and risk assessment of hazardous chemicals. 

Creation of the National Chemical Registry

One of the central elements of the regulation is the creation of the National Registry of Chemical Substances (RENASQ). This registry is intended to function as Peru’s national inventory of chemical substances manufactured, imported, or used in the country.

Through RENASQ, the authorities will collect key information on chemical substances placed on the Peruvian market, supporting stronger regulatory oversight and more informed decision-making.

Adoption of GHS Classification and Communication Requirements

The regulation adopts the GHS from its sixth revised edition (2015) onwards and requires that all chemical substances sold or used in Peru are classified, labelled and accompanied by an SDS in accordance with its standards.

Early Hazard Classification List as a Transition Tool

To support the transition to the new system, the regulation introduces the Listado de Clasificación Anticipada de Peligros (LCA), or Early Hazard Classification List. The LCA is published as Annex 3 of the regulation.

This list serves as an initial reference point for manufacturers and importers when classifying substances. However, it provides only a minimum classification basis and should not be considered exhaustive. Companies remain responsible for ensuring that their classifications reflect the available hazard information for each substance.

Electronic Reporting System

The environmental authority is establishing an electronic portal for chemical reporting where the notifier will be able to submit all the requested information. This includes:

• Details of the manufacturer or importer
• Identification of the chemical including IUPAC and CAS number, when available
• Recommended use of the chemical
• Quantity manufactured or imported of the chemical during the previous year
• Content of the SDS (in Spanish)
• Risk assessment of chemical substances for health and the environment, where appropriate, in accordance with the provisions of Article 9 of this Legislative Decree

Notification Threshold Still to be Defined 

Unlike some other Latin American chemical regulatory systems, Peru has not yet established a fixed quantitative threshold for notification. Instead, the Ministry of the Environment is expected to determine the minimum quantity that will trigger mandatory notification through a separate decree in the second half of 2027.

This means that, for the time being, companies should prepare for future reporting obligations while monitoring the publication of the threshold requirements.

Phased RENASQ Reporting Timeline

RENASQ reporting will follow a gradual implementation schedule. Companies that notified substances matching the LCA classification will begin reporting from 2029.

For substances with classifications that differ from the LCA, reporting will start from 2030. Substances not included in the LCA will be subject to reporting from 2031.

This phased approach gives industry stakeholders additional time to assess their portfolios, prepare the required data, and adapt to Peru’s new chemical management system.
