When manufacturers hear about Mexico’s NOM certification, their first thoughts are usually “hire an agent”, “send samples”, and “wait for the report”. But if asked about the latest updates to NOM ANCE certification, most would struggle to answer—and that’s not their fault. The truly critical “new changes” are often hidden beneath the surface of the standard process.
Explaining these updates is the key to unlocking the true value of NOM ANCE certification. Its latest developments are not just about revised standard numbers, but about improved certification convenience, upgraded standards, and a shift in how businesses approach certification strategy.
Before diving into the “new” details, we must anchor on the core definition: NOM ANCE certification is Mexico’s mandatory product certification system for all household appliances and similar products. This includes air conditioners, refrigerators, washing machines, televisions, electric fans, household lighting fixtures, and more—its jurisdiction is clear and non-overlapping with other NOM certification schemes (e.g., NOM NYCE for electronics).
At its core, NOM ANCE certification is a dual threshold of local law + technical standards:
1. Legal Threshold (Non-Negotiable Rule)
Under Mexican law, the legitimate holder of a NOM certificate must be a company registered in Mexico (usually your importer or designated local agent). Overseas manufacturers cannot hold certificates directly. This means your Mexican partner is not just a “contact person”, 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.
2. Technical Threshold (Core Requirement)
Products must pass laboratory testing to prove compliance with Mexico’s official NOM standards, which fall into two key categories:
·Safety Standards: e.g., NOM-003-SCFI, the non-negotiable baseline for protecting users against electric shock, fire, and other hazards.
·Energy Efficiency Standards: Mandatory for high-energy-consumption appliances such as air conditioners and refrigerators. This is the most dynamic part of ANCE certification, with regular updates—making it a critical focus for ongoing compliance.
II. Key 2025-2026 Updates & Trends for NOM ANCE Certification
With this core understanding, the true “new” developments in NOM ANCE certification become clear—they focus on making compliance more efficient, rigorous, and aligned with global sustainability trends:
1. Improved Testing Convenience: No More “Crossing the Ocean” for Samples
In the past, most NOM certification sample testing required shipping products to accredited laboratories in Mexico, which was time-consuming and costly. A significant current trend is the “forwarding and localization” of testing services: international certification bodies now offer NOM-compliant testing in China for many household appliance categories.
Proactively consulting these localized testing services is a new path to shorten project timelines and reduce costs—it eliminates the need for international sample shipping and allows for faster issue resolution (e.g., design modifications for failed testing) with your local testing team.
2. Continuous Standard Upgrades: Focus on Energy Efficiency & Niche Product Categories
Mexico’s technical standards (NOM) are not static—they are regularly evaluated and updated to align with global safety and sustainability benchmarks. Notable recent and upcoming updates include:
·LED Lighting Products: Mexico’s Secretariat of Economy released the new standard NMX-I-J-324-NYCE-ANCE-2022, outlining safety requirements and testing methods for self-ballasted LED lamps under 150W. While this is a voluntary NMX standard (not mandatory NOM), it reflects the latest industry consensus on technical specifications for this product category—and voluntary standards often become mandatory in future updates.
·Energy Efficiency Requirements: This is the most variable part of ANCE certification for household appliances. While no specific 2025 energy efficiency standard updates for ANCE-jurisdiction products have been formally announced, standard iteration is the norm (e.g., NOM-ENER standards for air conditioners and refrigerators). The most practical approach is to verify the latest version of your product’s applicable energy efficiency standard with a certification body or the Mexican Ministry of Economy before launching your project.
3. Tighter Overall Market Compliance
While not unique to ANCE certification, Mexico’s market compliance environment is becoming increasingly rigorous—and this has a direct impact on all products entering the market:
·Customs & Market Supervision: Mexican customs and the Federal Consumer Protection Agency (PROFECO) are conducting more stringent inspections. Product labels must be in Spanish and include complete information (NOM mark, certificate number, certificate holder details). Any non-compliance can result in customs clearance delays or heavy market penalties.
·Trade Rule Changes: Mexico updated its general foreign trade rules in 2026, with tariff increases for some product categories. While this does not directly impact ANCE certification, it is a new factor to include in your overall market cost assessment for Mexico.
III. Key Business Recommendations: How to Adapt to These New Changes
To leverage these updates and avoid compliance risks, businesses should adopt a more proactive certification strategy:
1.Re-Evaluate Your Testing Path: Proactively consult certification service providers to explore the possibility of completing partial or full pre-testing/compliance testing in China. This can significantly reduce the time and cost of international sample shipping and speed up issue resolution.
2.Build a “Standard Tracking” Habit: Do not rely on outdated experience (1-2 years old). Develop a quarterly habit of checking the latest safety and energy efficiency standards through your certification partner or the Mexican Ministry of Economy’s official channels—this small step avoids costly re-testing due to outdated standards.
3.Deeply Partner with Your Local Certificate Holder: Treat your Mexican certificate holder as a strategic compliance partner, not just a logistics channel. A professional, reliable local partner can efficiently respond to market inspections, assist with standard updates, and handle product recall coordination—their value far exceeds their agency service fee.
4.Budget for the “Annual Compliance Audit”: NOM ANCE certificates have a 1-year validity period, and renewal requires random market sampling and retesting (not just a fee payment). Be sure to include these potential annual supervision costs and timelines in your long-term Mexican market planning.
Understanding the “latest updates” to NOM ANCE certification means shifting from “passively completing a testing task” to “proactively managing a dynamic compliance project”. Its core has not changed—it is still a dual threshold of local legalization and technical standardization. But the path to compliance is becoming faster and clearer, and it demands greater professionalism and vigilance from businesses entering the Mexican market.
