In April 2026, Peru formally adopted long-awaited implementing regulations for its national chemical legislation, marking a significant milestone in the country’s transition to a comprehensive chemicals management framework.
The Ministry of the Environment (MINAM) approved Supreme Decree No. 005‑2026‑MINAM, establishing detailed rules for the implementation of Legislative Decree No. 1570, which governs the integrated management of chemical substances and introduces the National Registry of Chemical Substances (RENASQ).
Adoption of GHS and Core Compliance Requirements
The regulation aligns Peru with the United Nations Globally Harmonised System (GHS), Revision 6, requiring manufacturers and importers to:
- Classify chemical substances according to GHS criteria
- Ensure compliant labelling in Spanish
- Prepare and maintain Safety Data Sheets (SDS)
- Submit hazard and substance information to RENASQ
The regulation also includes a list of anticipated hazard classifications (Annex 3), which serves as a reference for companies but does not replace the obligation to perform a full classification.
Entry into Force and Transitional Period
Although the regulation has been published, it will enter into force approximately six months after publication (October 2026).
A key feature is the introduction of a phased implementation period extending from 2028 to 2031, allowing companies time to adapt to new requirements.
The regulation provides an “adaptation period” during which authorities will focus on advisory supervision and no penalties will apply, allowing companies to prepare for full compliance.
Phased Registration and Reporting Deadlines
The regulation distinguishes between hazard notification (submission of classification, labelling, and SDS information) and RENASQ reporting (annual reporting of substance volumes).
RENASQ reporting deadlines are as follows:
- 2029 – Hazardous substances classified in accordance with the LCA (Advance Hazard Classification of Chemical Substances), including those with additional notified hazard classes;
- 2030 – Hazardous substances that have been notified and have a classification different from that established in the LCA;
- 2031 – Hazardous substances not listed in the LCA that have been reported.
Deadlines for notifying hazardous substances are from 1 January to 30 September in the following years:
- 2028 – Substances classified in accordance with the LCA or with additional hazard classes;
- 2029 – Substances with a classification different from that established in the LCA;
- 2030 – Substances not listed in the LCA; and
- 2031 – Non-hazardous substances.
A voluntary pilot phase for the RENASQ system is scheduled during 2028, allowing companies to test submissions and support the development of the system.
Implications for Industry
With the adoption of these regulations, Peru establishes a REACH-like, lifecycle-based framework comparable to chemical management systems in other major jurisdictions, incorporating:
- Harmonised hazard communication (GHS)
- Centralised substance registration (RENASQ)
- Risk-based prioritisation of chemicals
Companies placing substances on the Peruvian market should begin preparing by:
- Reviewing existing GHS classifications
- Updating SDS and labels to meet Spanish-language requirements
- Establishing systems for data collection and reporting
National inventories
The regulations establish three MINAM-managed inventories:
- National Inventory of Chemical Substances (incl. RENASQ): Covers all substances manufactured or imported in Peru; published Q4 2031 and updated annually.
- ERSQ Inventory: Covers substances subject to national risk assessment; planned for publication from 2035 and updated annually.
- Inventory of Hazardous Facilities: Development begins in 2031, using RENASQ data to identify facilities with potential transboundary impacts.
Conclusion
The approval of Supreme Decree No. 005‑2026‑MINAM marks Peru’s transition from consultation to implementation of a comprehensive chemicals management regime. While obligations will be introduced gradually through 2031, early preparation will be essential for companies to ensure compliance with upcoming GHS and RENASQ requirements.
