Mexico published a new Regulation of the Quality Infrastructure Law on September 4, 2026. The new instrument establishes the administrative framework for Mexico’s Quality Infrastructure Law.
It covers standardization, accreditation, certification, conformity assessment, metrology, verification, and market surveillance. The Mexico Quality Infrastructure Regulation takes effect on September 7, 2026. On that date, it replaces the previous Regulation of the Federal Law on Metrology and Standardization.
Mexico Quality Infrastructure Regulation: Transition Rules
Existing conformity assessment documents will not automatically expire on September 7. Organizations may continue using these documents under their current terms.
However, the documents must remain consistent with the Quality Infrastructure Law and the new Regulation. They will remain valid until the relevant authorities or conformity assessment bodies issue replacements.
The Regulation gives existing authorizations, accreditations, and approvals a three-year renewal period. Their holders must renew them according to the new legal framework. If they miss the deadline, the authorities will cancel them.
Authorities will continue reviewing applications filed before September 7 under the previous requirements. This provision applies to accreditation and approval applications submitted before the effective date.
Therefore, the new Regulation does not automatically transfer pending applications to the new procedure.
Important compliance callout: Existing conformity assessment documents remain valid after September 7, 2026. Companies should still confirm that their documents comply with the new framework. They should also monitor future replacement requirements.
Administrative Provisions and PLATIICA
Authorities have up to 12 months after the effective date to issue pending administrative provisions. These measures may include internal rules, guidelines, procedures, and interpretation criteria.
Additionally, the Secretariat may introduce temporary procedures and formats while it updates PLATIICA. Compliance teams should monitor the platform for new instructions and implementation guidance.
PLATIICA will support several activities under the new framework. These activities include publishing regulatory information, procedures, criteria, and recognition arrangements.
Transition from Mexican Standards
Existing Mexican Standards will remain valid during the transition. The Secretariat will cancel them when a new Standard covers the same subject. It may also publish a formal cancellation declaration in the Official Gazette.
Once the relevant Technical Standardization Committees begin operating, responsible organizations must develop new Standards. They have a non-extendable period of 36 months following the Regulation’s entry into force.
This requirement applies to areas where Mexican Standards currently regulate products, processes, services, sectors, or activities. If the responsible organizations miss the deadline, the Secretariat will publish the corresponding cancellations.
An exception applies when an Official Mexican Standard references a Mexican Standard. In that situation, the Mexican Standard remains valid until the authority amends the corresponding Official Mexican Standard.
Market Surveillance Requirements
The Regulation requires each competent authority to create an annual market surveillance program. Each authority must submit its program to the Commission for evaluation.
Authorities may conduct verification and surveillance throughout the supply chain. Their inspections may cover manufacturing, processing, storage, transportation, distribution, and sales locations.
They may also inspect service locations and products in transit. Moreover, authorities may start surveillance procedures at any time. A complaint may also trigger a procedure when it indicates potential non-compliance.
Companies operating in Mexico should review their existing approvals, applications, and conformity assessment documents. They should also monitor PLATIICA and new administrative provisions.
