Chemical regulation in Mexico (2026) is governed by a multi-agency framework rather than a single unified law. While the proposed General Law for the Integral Management of Chemical Substances (LGGISQ) remains pending, companies must comply with existing regulations such as the General Health Law, NOM standards, and requirements from authorities like Federal Committee for Protection from Sanitary Risks, and Secretariat of Environment and Natural Resources. Compliance includes permits, labeling (GHS), Safety Data Sheets (SDS), and import/export authorizations depending on chemical classification.

Introduction

Mexico represents a strategically important market for chemicals, industrial products, agrochemicals, and hazardous materials. However, unlike the EU REACH framework, Mexico does not yet have a comprehensive national chemical regulation law.

Instead, chemical management is governed through:

• Sector-specific laws 
• Technical standards (NOM, NMX, NRF) 
• Multi-agency oversight 

In 2019, the General Health Council (CGS) proposed the General Law for the Integral Management of Chemical Substances (LGGISQ) to establish a unified regulatory system. Although still pending, this law is expected to transform chemical compliance in Mexico.

This 2026 guide by Maven Regulatory Solutions provides a comprehensive, technical overview of current regulations, compliance requirements, import/export procedures, and future regulatory developments.

Mexico Chemical Regulatory Landscape (2026 Update)

National Law on Chemicals (LGGISQ – Pending)

The proposed LGGISQ aims to establish a comprehensive chemical management system.

Key Objectives:

• Creation of National Registry of Chemical Substances (ReNaSQ) 
• Mandatory registration dossiers for chemicals 
• Risk-based chemical safety assessments 
• Authority to impose restrictions and bans 
• Obligation for companies to submit periodic data 

Expected Dossier Requirements

Status (2026):

• Still pending approval 
• No confirmed timeline 
• Delays due to multi-agency coordination complexity 

Existing Chemical Regulations in Mexico

Until LGGISQ is enacted, companies must comply with:

1. General Health Law

Defines:

• Toxic substances 
• Pesticides 
• Fertilizers 

Requires:

• Registration 
• Permits 
• Labeling compliance 

2. Sanitary Control Regulations

Covers:

• Manufacturing 
• Import/export 
• Distribution 
• Product safety 

3. Ecology Law

Focus:

• Environmental protection 
• Soil contamination prevention 
• Restrictions on hazardous imports 

Chemical Inventory in Mexico

The National Inventory of Chemical Substances (Base 2009):

• Contains ~5,800+ substances 
• Includes: 
  • CAS numbers 
  • Molecular data 
  • Ecotoxicological information 

Key Points:

• Not mandatory 
• Used for reference and statistical purposes 
• Updated proposals suggest lifecycle-based evaluation

• Proper labeling and hazard communication 
• Registration/permit for regulated substances 
• Transport authorization (SCT) 

Import & Export Requirements

1. Non-Toxic Chemicals

• Notification to Comisión Federal para la Protección contra Riesgos Sanitarios 
• Online submission form 
• No fee required 

2. Toxic Chemicals

Required Documents:

• Application form 
• Legal entity proof 
• Sanitary license 
• Safety Data Sheet (Spanish) 
• Proof of payment 

Additional Requirements:

• RUPA registration (optional but recommended) 
• Legal representative authorization 
• Signed documentation (physical/electronic) 

Chemical Transport Compliance

Regulated by SCT:

• Mandatory permits for hazardous materials 
• Packaging compliance (NOM standards) 
• Labeling requirements for transport 

Workplace Safety & Chemical Handling

Regulatory Focus:

• Worker exposure limits 
• Safe storage and handling 
• Emergency response procedures 

Key Standard:

• NOM-005-STPS-2008 

Key Compliance Challenges in Mexico

Outlook: Mexico Chemical Regulation 

• Implementation of LGGISQ 
• Establishment of ReNaSQ registry 
• Stronger enforcement of GHS compliance 
• Digitalization of regulatory submissions 
• Alignment with global chemical regulations (REACH-like systems) 

Conclusion

Chemical regulation in Mexico remains complex and evolving, requiring companies to navigate multiple laws, standards, and authorities. While LGGISQ promises a unified framework, current compliance depends on strict adherence to NOM standards, COFEPRIS permits, and environmental regulations.

Maven Regulatory Solutions supports companies with:

• Mexico chemical compliance strategy 
• SDS and GHS classification 
• NOM standards alignment 
• Import/export regulatory support 
• Future LGGISQ readiness
