Mexico - Inventory

Mexico's National Inventory of Chemical Substances (INSQ) is a comprehensive database established to catalogue chemical substances produced, imported, or marketed in the country. This initiative is managed by the Secretariat of Environment and Natural Resources (SEMARNAT), with technical support from the National Institute of Ecology and Climate Change (INECC). The INSQ plays a critical role in Mexico's strategy to enhance chemical safety, promote environmental protection, and protect public health. 

Overview of the INSQ: 

The INSQ was formally established to address gaps in chemicals management and to establish a centralized inventory of chemical substances. At the time of the 2015 update, the inventory identified 9,489 chemical substances actively in commerce, including both industrial and consumer chemicals. These substances are assessed for persistence, bioaccumulation, and toxicity, particularly in aquatic environments. 

Obligations for Substances in the INSQ: 

• Compliance Requirements: Substances listed in the INSQ must comply with established regulations, including labelling, classification, and the preparation of Safety Data Sheets (SDS). This ensures proper hazard communication and safe handling practices. 

Obligations for Substances Not in the INSQ: 

• Pre-Market Risk Assessment: Substances not included in the INSQ are considered new chemicals. These substances require comprehensive pre-market risk assessments to evaluate their environmental and health impacts. Approval is mandatory before such substances can be marketed or used in Mexico. 

Voluntary Reporting Nature of INSQ: 

The reporting process for substances to be included in the INSQ is voluntary. Manufacturers and importers are encouraged to report their chemical substances to enhance regulatory oversight and strengthen safety and compliance efforts. 

Confidentiality Provisions: 

The INSQ includes mechanisms to protect confidential information. Manufacturers and importers can submit justifications for keeping sensitive data confidential, subject to review by regulatory authorities. This provision balances commercial interests with public access to chemical safety information. 

Regulatory Focus: 

The INSQ is aligned with the Globally Harmonized System (GHS) for Classification and Labelling of Chemicals. This alignment emphasizes systematic risk assessment and hazard communication to support regulatory compliance, protect workers, and reduce environmental risks. 

Key Dates and Updates: 

• 2009 Creation of the Chemical Inventory: 5852 substances identified  

• 2015 Update: The inventory was reported to include 9,489 chemical substances. 

By consolidating critical safety data and enforcing robust regulations, the INSQ serves as a vital tool in Mexico's efforts to manage chemical risks and ensure the responsible use of chemical substances throughout their lifecycle.
