Mexico’s NOM certification is a mandatory requirement for market entry. Below is a streamlined overview of the process, timeline, and key considerations based on 2025 regulations.
1.Preparation (1–2 weeks)
·Identify Standards: Check the Mexican Ministry of Economy (SE) website for applicable NOM standards.
·Local Representative: Appoint a Mexican entity (importer or subsidiary) as the certificate holder.
·Documentation: Prepare Spanish technical files, including manuals, circuit diagrams, and component lists.
2.Testing & Review (4–12 weeks)
·Sample Testing: Send samples to a Mexican-accredited lab for safety (e.g., dielectric strength, insulation resistance), EMC, and energy efficiency tests. CB reports can expedite but usually require local Difference testing.
·Factory Audit: Required for quality system-based schemes (e.g., M2 mode).
3.Approval & Certification (2–4 weeks)
·Upon successful testing/audit, the certification body issues the NOM certificate.
·Products must carry the NOM mark before market entry.
4.Post-Certification Surveillance： Annual supervision includes sample testing (M1 mode) or factory audits (M2 mode).
2025 Key Changes:
1.Dual Certificate System: Product conformity and market access are now separate.
·M1 Mode (product testing): 1-year validity.
·M2 Mode (quality system): 3-year validity.
2.Centralized Process: All applications must go through official Mexican systems, potentially extending timelines.
3.Local Requirements: Overseas manufacturers must appoint a Mexican representative, and all goods must enter designated Mexican warehouses (no "port-to-door" shipping).
