Normas Oficiales Mexicanas - NYCE (NOM NYCE) certification exclusively governs electronic, information, and data processing equipment. Its core is verifying product safety and compliance through standardized testing, serving as the technical passport for products to enter the Mexican market. Combining the latest 2026 standard updates, official jurisdiction lists, and real-world case studies, this article breaks down NOM NYCE’s standard system, core testing items, and detailed product coverage to help you accurately match products with the right standards and avoid 90% of category misclassification and standard selection mistakes.
1. Clear Jurisdiction Boundaries: Only Electronic/Information/Data Processing Equipment—Household Appliances Fall Under ANCE
NOM NYCE and NOM ANCE are the two core mandatory certification systems in Mexico, with strict, non-overlapping jurisdiction. Misclassifying a product will result in immediate application rejection:
·NOM NYCE Jurisdiction: Electronic equipment (power adapters, printers), information products (routers, computers), data processing equipment (servers, POS terminals). Microwaves are the only exception—though classified as appliances, they fall under NOM NYCE.
·NOM ANCE Jurisdiction: Household appliances such as air conditioners, refrigerators, and washing machines. Even smart appliances (e.g., Wi-Fi-enabled air conditioners) require NOM ANCE for electrical safety certification; only their wireless functions require additional IFETEL certification.
2. Standard Logic: Basic Safety + Specialized Functionality—Wireless Products Require Additional RF Standards
NOM NYCE’s standard system is not a one-size-fits-all approach, but rather split into basic standards + specialized standards based on product functionality:
·All products must pass basic safety standards (e.g., electrical safety, insulation protection).
·Products with wireless functions (Bluetooth, Wi-Fi) must comply with additional IFETEL radio frequency (RF) standards.
·Products with network functionality have been required to meet IPv6 protocol standards since July 2025.
II. 2026 NOM NYCE Certification Standards & Testing Items
1. Basic Safety Standards: Mandatory for All Products
These are the core requirements of NOM NYCE, applicable to every product category, primarily based on the NOM-001 and NOM-019 series of standards:
NOM-001-SCFI-1993 (Safety of Audio-Visual Equipment)
Core Testing Items: Hi-pot testing (prevent electric shock), insulation resistance testing (avoid electric leakage), temperature rise testing (prevent overheating and fire). This standard applies to products such as speakers and monitors.2026 Update: New abnormal operating condition testing has been added to simulate product safety performance during malfunctions (e.g., short-circuit protection).
NOM-019-SCFI-1998 (Safety of Information Technology Equipment)
Core Testing Items: Electric shock protection (chassis grounding continuity), basic EMC testing, mechanical strength testing (impact resistance for enclosures). This standard applies to computers, routers, POS terminals, and more.Pitfall to Avoid: Many businesses mistakenly believe EMC testing is optional, but NOM-019 explicitly requires basic EMC testing to prevent product interference with other devices.
2. Specialized Functionality Standards: Additional Product-Specific Testing
Beyond basic safety, products with specific functions must comply with specialized standards—a detail many businesses overlook:
Wireless Products (Bluetooth Speakers, Wi-Fi Routers)
Mandatory Additional Standards: IFETEL NOM-208-SCFI (RF performance), NOM-211-SCFI (enhanced EMC).Core Testing Items: Transmit power testing (to avoid interference with Mexican communication frequency bands), IPv6 protocol compatibility testing (mandatory since July 2025), Bluetooth pairing safety testing.Real-World Case: A Shenzhen router manufacturer failed testing due to a 0.5dBm transmit power excess; modifying the antenna design to pass testing added an extra 2 weeks to the project timeline.
Power Adapters & Chargers
Mandatory Additional Standards: NOM-001-SCFI-1993 (for audio-visual equipment) or NOM-019-SCFI-1998 (for IT equipment) + NOM-037-SCFI-2013 (energy efficiency standard).Core Testing Items: Energy efficiency rating testing (must meet Mexican MEPS Level 6), no-load power consumption testing (≤0.5W), overcurrent/overvoltage protection testing.2026 Update: Energy efficiency standards have been upgraded—charger no-load power consumption limits have been reduced from ≤1W to ≤0.5W. Non-compliant products will be rejected immediately.
Servers & Data Processing Equipment
Mandatory Additional Standards: NOM-019-SCFI-1998 + NOM-029-SCFI-2003 (thermal safety).Core Testing Items: Cooling fan reliability testing, long-term operational stability testing (72 consecutive hours of trouble-free operation).
3. Label & Document Standards: Overlooked Compliance Requirements
Updated label and document requirements were introduced in March 2025—non-compliance will result in certification failure, just like failed testing:
·Label Standards: Must include the NOM NYCE mark, certificate number, certificate holder information, and a QR code (for customs traceability). Font size must be ≥8mm, and labels must be affixed to the product itself (packaging-only labeling is invalid).
·Document Standards: Technical manuals and user guides must be in Spanish and include safety warnings (e.g., “Keep out of reach of children”), product specifications, and a test report summary.
·Test Report Requirements: Must be issued by a laboratory accredited by the Mexican Ministry of Economy. Reports from domestic Chinese laboratories require endorsement by an officially recognized mutual recognition body.
III. 2026 NOM NYCE Certification Covered Products
1. Explicitly Covered Products (Direct Matching)
·Electronic equipment: Power adapters, chargers, monitors, printers, scanners, projectors, speakers, non-Bluetooth headphones.
·Information and communication equipment: Desktops/laptops, tablets, routers, switches, network cards, POS terminals, modems.
·Data processing equipment: Servers, storage devices, industrial control computers (without wireless functionality).
·Special covered product: Microwaves (the only household appliance category under NOM NYCE jurisdiction).
2. Newly Added Covered Products (2025-2026)
·Smart electronic equipment with network functionality: Smart gateways, network cameras (without wireless functionality), wired smart home controllers.
·New energy-related electronic equipment: Energy storage battery management systems (BMS, without wireless functionality), charging pile control modules.
3. Easily Misclassified Products (Avoid the Wrong Certification Path)
·NOM ANCE Jurisdiction: Smart air conditioners, Wi-Fi-enabled refrigerators, power tools (even with basic electronic controls). Their electrical safety falls under NOM ANCE; only wireless functions require IFETEL certification.
·IFETEL Exclusive Jurisdiction: Pure wireless communication devices (e.g., Bluetooth headphones, Bluetooth modules). These require NOM NYCE safety certification first, followed by separate IFETEL RF certification.
·No NOM NYCE Required: Standard data cables, phone cases, non-smart electronic accessories (e.g., keyboard protectors). Low-risk accessories are exempt from mandatory NOM NYCE certification.
IV. 2026 Key Standard Updates: 3 Changes Impacting Certification Directly
1.Energy Efficiency Standard Upgrade: Power adapters and chargers must comply with NOM-037-SCFI-2024 (no-load power consumption ≤0.5W). Test reports based on old standards will be invalid starting January 2026.
2.Mandatory IPv6 Testing: All network-enabled products (routers, smart gateways) must pass testing to RFC 8200/8505/9096 standards. Basic connectivity testing alone is no longer sufficient.
3.Mandatory QR Codes on Labels: Since March 2025, labels must include a customs traceability QR code applied for by the certificate holder through the Mexican Ministry of Economy’s system. Products without a QR code will be deemed non-compliant by Mexican customs.
V. Pitfall Avoidance Guide: 3 Common Product-Standard Matching Mistakes
1.Only completing NOM-019 testing for Bluetooth speakers: Overlooking IFETEL RF and IPv6 testing will result in application rejection—you will need to complete supplementary testing and resubmit.
2.Applying for NOM NYCE for smart air conditioners: Electrical safety for air conditioners falls under NOM ANCE; you should first obtain NOM ANCE certification, then apply for IFETEL wireless certification for the smart function.
3.Testing power adapters to old energy efficiency standards: Using NOM-037-2013 instead of the updated 2024 version will require full retesting.
The key to NOM NYCE certification is not memorizing standard numbers, but understanding the logic of product type → core functionality → corresponding standards: standard electronic equipment only needs to meet basic safety standards, while wireless/network-enabled products require additional specialized standards. Never confuse NOM NYCE with NOM ANCE for household appliances. The 2026 compliance priorities are keeping up with the three major changes: energy efficiency upgrades, mandatory IPv6 testing, and QR code labeling. Avoid certification failure due to outdated standards or product misclassification.
