What actually changes, and on which date
Peru has regulated specific hazardous substances for decades, but it never had one general law covering the full lifecycle of chemical substances until Legislative Decree No. 1570, published 29 May 2023, created the Ley de Gestión Integral de Sustancias Químicas (Law on Integral Management of Chemical Substances). That law binds every natural or legal person, public or private, operating in Peru who manages or uses chemical substances, and it carves out two exemptions: naturally and artificially radioactive substances, and substances in customs transit on their way to another country. The law set the framework. It left classification, labelling, safety-data-sheet and registry rules to a future regulation.
That regulation is Supreme Decree No. 005-2026-MINAM, published 8 April 2026. It adopts GHS Revision 6: hazard classification becomes the manufacturer's responsibility, while the importer must ensure the classification, Spanish-language label and safety data sheet are in place before a product is sold or used in Peru. Labels must carry the product identifier, hazard pictograms, signal words, hazard and precautionary statements, and the manufacturer's or importer's name, address and phone number; the safety data sheet, provided free of charge by the manufacturer or importer, must be available in physical or digital form at every point of use. The regulation also creates RENASQ, a declarative registry of hazardous substances manufactured or imported into Peru, administered by MINAM, with annual reporting due between 1 January and 31 March. All of this becomes law on 9 October 2026, six months after publication, as the decree's own transitory provisions require. But a separate provision, in the same decree, opens an adequacy period from 1 January 2028 to 30 September 2031: during that window, manufacturers, importers, distributors, transporters and users are explicitly exempt from sanctions tied to classification, labelling, safety-data-sheet and RENASQ obligations, and MINAM's enforcement authorities are limited to preventive supervision. RENASQ itself only opens for voluntary registration from 1 January 2028, with phased mandatory rollout starting in 2029.
Three details behind the 9 October rule
01
In force on 9 October, enforceable later
DS 005-2026-MINAM takes legal effect six months after its 8 April 2026 publication, but the GHS duties it creates carry no sanction until the adequacy period starts.
02
No sanctions, by the decree's own design
From 1 January 2028 to 30 September 2031, manufacturers, importers, distributors, transporters and users are explicitly exempt from sanctions, with regulators limited to preventive supervision.
03
A registry that opens in 2028, not 2026
RENASQ, the national chemical substances registry, accepts only voluntary filings from 1 January 2028, with mandatory phased rollout beginning in 2029.
29 May 2023
Legislative Decree No. 1570 is published, creating the Ley de Gestión Integral de Sustancias Químicas, Peru’s framework law for chemical substances.
8 Apr 2026
MINAM publishes Supreme Decree No. 005-2026-MINAM, adopting GHS Revision 6 for classification, labelling and safety data sheets, and creating the RENASQ registry.
9 Oct 2026
The regulation enters into force, six months after publication, as its own transitory provisions require.
1 Jan 2028
The adequacy period begins: RENASQ opens for voluntary registration, and sanctions for GHS and registry duties are suspended.
30 Sep 2031
The adequacy period ends; full enforcement, with sanctions, begins across the chemical substance supply chain.
The numbers behind the 9 October rule
One number is the gap between the regulation being published and taking legal effect. One is the window during which its core duties carry no sanction. The third is the hazard-classification edition every label and safety data sheet it requires must follow.
6 months
between DS 005-2026-MINAM's publication on 8 April 2026 and its entry into force on 9 October 2026
2028 to 2031
the adequacy period (1 January 2028 to 30 September 2031) during which GHS classification, labelling, SDS and registry duties carry no sanction
GHS Rev. 6
the hazard classification and labelling edition Peru adopts for chemical substances, the same one referenced on every label and safety data sheet the regulation requires
The real subject: entering into force is not the same as being enforced
Most coverage of DS 005-2026-MINAM since its April publication has read 9 October 2026 as the date Peru's chemical compliance regime starts to bind companies. That is true of the regulation's legal existence and false of its enforcement. The decree itself draws the line: the GHS classification, labelling, safety-data-sheet and RENASQ registry duties it creates become law on 9 October 2026, but the decree's own adequacy-period provision exempts manufacturers, importers, distributors, transporters and users from sanctions for those same duties until 30 September 2031, and limits enforcement authorities to preventive supervision for the three years and nine months in between. A regulation that is legally in force and a regulation whose duties can actually be penalized are two different facts, and the decree keeps them on two different calendars. For a company tracking compliance deadlines by a single headline date, that distinction is the one most likely to be missed, and the one that actually determines when a non-compliant label or missing safety data sheet starts to carry risk.
Why it matters for brands
DS 005-2026-MINAM does not target one finished-product category; it reaches any manufacturer or importer of chemical substances sold or used in Peru, which in practice means the raw materials, coatings, dyes, adhesives, cleaning formulations and cosmetic ingredients that sit inside apparel, footwear, cosmetics, household and personal-care products, toys and furniture. A brand sourcing those inputs from, or importing finished goods into, Peru should not read the adequacy period as permission to wait until 2028. The decree suspends sanctions for classification, labelling, SDS and RENASQ duties; it does not suspend the duties themselves, and GHS Revision 6 classification data, once built for a supplier's product, does not change on 1 January 2028, only the enforcement risk attached to missing it does. Brands that start mapping which inputs count as chemical substances under DL 1570, collecting manufacturer-level GHS classifications and Spanish-language safety data sheets now, and structuring that data so it can feed RENASQ once mandatory registration begins in 2029, arrive at 30 September 2031 with a compliance record already built. Brands that wait for the sanction clock to start will be assembling, under enforcement pressure, the same supplier-level chemical data that is available to collect today without any penalty for being incomplete.
Two ways to read the 9 October rule
The narrow read
On 9 October 2026, Peru's chemical substances regulation becomes law, requiring GHS classification, labelling and safety data sheets for chemical substances manufactured or imported into the country.
The structural read
That legal entry into force carries no enforcement weight on its own: the decree explicitly exempts companies from sanctions for those same classification, labelling and registry duties until 2028, and gives them until 30 September 2031 to fully comply, making 9 October 2026 a start date for preparation, not for penalties.
