Mexico’s NOM ANCE certification is far more than just a certificate—it’s a compliance system tailored for household appliances, integrating technical barriers and local legal requirements. Many articles on the market confuse it with NOM NYCE or only list standard numbers; today, we’ll uncover its complete scope and requirements.
First and foremost, we must draw a clear line. Mexico’s mandatory NOM certification is administered by multiple bodies, and the jurisdiction of ANCE (Asociación de Normalización y Certificación) is extremely clear: all household appliances and similar products.
What does this mean? If your product’s core function is “household use”—supporting energy conversion, food preparation, environmental control, and other daily living needs—it almost certainly falls under ANCE jurisdiction.
1. Typical Covered Products
Air conditioners, refrigerators, washing machines, televisions, microwaves (a notable exception often highlighted in the appliance category), electric fans, vacuum cleaners, electric irons, induction cooktops, and household lighting fixtures, among others.
2. Core Characteristics
These products typically run directly on mains power (127V/60Hz) and are closely integrated into daily life. Their safety and energy consumption directly impact consumer personal and property safety, as well as public interests—this is why ANCE certification is mandatory.
II. NOM ANCE Certification: Technical Standards + Local Legal Requirements
To enter this “jurisdiction”, you must cross two non-negotiable barriers:
1. Technical Barrier: Safety as the Baseline, Energy Efficiency as a Key Focus
Safety Standards (Non-Negotiable Baseline)
This is the mandatory market access threshold. The most common safety standard is NOM-003-SCFI, which outlines general safety requirements for household appliances, including protection against electric shock, fire, and mechanical hazards. Products must pass testing by an accredited laboratory to prove compliance with these standards.
Energy Efficiency Standards (Focus & Latest Updates)
This is the fastest-changing and most easily overlooked aspect of ANCE certification. In addition to safety, many household appliances must meet mandatory energy efficiency (NOM-ENER) requirements. A critical point to note: Mexico’s energy efficiency standards are constantly being upgraded. For example, air conditioners, refrigerators, and other high-energy-consumption appliances have corresponding energy efficiency standards, and the Mexican government regularly updates and tightens these metrics. Your product may also need to display an official energy consumption label—this is often a separate process from safety certification.
2. Legal Barrier: The Non-Negotiable “Certificate Holder” System
This is the core rule of Mexico’s NOM certification system and the key difference from many international certification schemes. Under Mexican law:
·The legitimate holder of a NOM certificate must be a company registered in Mexico (usually your importer or a legally designated local agent).
Overseas manufacturers cannot hold NOM ANCE certificates directly. This means your Mexican partner is not just a logistics channel, but the legal liability holder for your product in the Mexican market. The original certificate will be sent directly to them for customs clearance purposes. Choosing a professional, reliable local certificate holder is the foundation of a successful ANCE certification project.
III. NOM ANCE Certification: Step-by-Step Process & Timeline
A typical NOM ANCE certification project usually takes 1.5 to 3 months, with longer timelines for complex products. The entire process can be broken down into four phases:
Phase 1: Strategic Preparation (1-2 weeks)
This is the internally controllable phase, with the core goal of “defining direction and finding a partner”:
·Precise Product Categorization: Confirm with 100% certainty that your product falls under ANCE jurisdiction (avoid misclassification with NOM NYCE).
·Secure a Certificate Holder: Sign a formal agreement with your Mexican importer to clarify their responsibilities as the certificate holder.
·Confirm the Latest Standards: Through a professional certification body or the Mexican Ministry of Economy’s official website, lock in the latest version of the safety and energy efficiency standards your product must comply with (outdated standards will result in application rejection).
Phase 2: Testing & Report Generation (Largest Variable: 4-8 Weeks or Longer)
This is the most time-consuming technical phase, with two testing paths to choose from:
·Local Mexican Testing: Send samples to a laboratory accredited by the Mexican government for full testing.
·Optimized Path (CB Report Conversion): If you hold an internationally recognized CB test report, you can use it as a basis for “certificate conversion”. This does not mean exemption from all tests. You must still complete Mexico-specific difference tests at an accredited laboratory (e.g., 127V/60Hz voltage adaptation, Spanish label verification). This path is typically faster than full local testing in Mexico.
Phase 3: Document Submission & Official Review (Approx. 5-6 Weeks)
All documents—including test reports, Spanish user manuals, and the certificate holder’s company documents—are submitted to ANCE by your local certificate holder. The official review cycle is relatively fixed, usually 5 to 6 weeks. After approval, ANCE will issue the certificate directly to your Mexican certificate holder.
Phase 4: Ongoing Maintenance (Annual Requirement)
NOM ANCE certificates have a standard 1-year validity period. Note: Renewal is far more than just paying a fee. The certification body will most likely require random product sampling from the Mexican market for retesting, and only products that pass this sampling will be eligible for a renewed certificate. This is a dynamic market supervision mechanism to ensure ongoing product compliance.
