Mexico Pesticide Registration

Definition and Classification of Pesticides in Mexico

In Mexico, a pesticide is defined as any substance or mixture of substances intended to prevent, destroy, repel, or mitigate any pest. To ensure precise oversight, the regulatory system classifies these products based on both their biological origin and their intended application area.

By Origin

• Chemical pesticides: Substances produced via chemical synthesis for direct pest control.
• Biochemical pesticides: Naturally occurring agents like pheromones that manage pests through non-toxic behavior modification.
• Microbial pesticides: Biological agents consisting of microorganisms such as bacteria or fungi.
• Botanical pesticides: Active substances extracted from plants used as natural pest management alternatives.
• Other pesticides: Products achieving pest control through unique physical or biological mechanisms not otherwise classified.

By Intended Use

• Agricultural Use: Products for crop protection, seed treatment, and soil maintenance.
• Household Use: Pesticides safe for use within residential and domestic environments.
• Forestry Use: Specialized formulations for preserving timber and forest ecosystem health.
• Industrial Use: Chemicals used to protect raw materials or treat recirculating industrial water.
• Horticultural Use: Pesticides for managed landscapes, nurseries, and ornamental plants.
• Livestock Use: Products for controlling external parasites affecting animals and their surroundings.
• Urban Use: Professional-grade products for pest management in cities, parks, and infrastructure.

Core Regulatory Framework and Standards

The registration process is governed by a robust hierarchy of laws and technical standards that harmonize domestic safety with international protocols:

• LGS (Ley General de Salud): The General Health Law providing the legal basis for sanitary control.
• PLAFEST Regulation: The specific regulation governing the registration, import, and export of pesticides, fertilizers, and toxic substances.
• Official Mexican Standards (Normas Oficiales Mexicanas, NOM): Including standards like NOM-232-SSA1-2009, which dictate requirements for labeling and data submission.

Primary Regulatory Authorities

Pesticide oversight in Mexico is a collaborative tripartite effort between three federal bodies:

• COFEPRIS

The Federal Commission for Protection against Sanitary Risk. It serves as the lead agency, evaluating human health risks and issuing the final Sanitary Registration Number.

• SEMARNAT

The Ministry of Environment and Natural Resources, which conducts specialized environmental impact and ecotoxicological assessments.

• SADER

The Ministry of Agriculture and Rural Development. It evaluates the agronomic efficacy of products intended for agricultural use.

Mexico Pesticide Registration Workflow

Only entities legally incorporated in Mexico are eligible to act as the registrant. The process follows a structured workflow:

Step 1: Dossier Compilation and Submission

The applicant prepares a technical dossier compliant with NOM standards. For agricultural products, technical opinions must be sought from SADER and SEMARNAT before COFEPRIS grants the final sanitary registration.

Step 2: Technical Evaluation

Each agency performs a specialized review within their jurisdiction:

• SADER: Reviews field trial data to issue a technical opinion on agronomic effectiveness.
• SEMARNAT: Evaluates environmental fate and risks to non-target organisms.
• COFEPRIS: Conducts a final toxicological review and integrates all technical opinions.

Step 3: Approval and Issuance

Once all technical criteria are met, COFEPRIS issues the formal Sanitary Registration Number, allowing the product to be legally marketed.
