NOM Certification — NYCE or ANCE Route Where Applicable China's domestic route may include CCC or voluntary CQC/CNAS-backed reports for EV charging equipment. Those certificates are not Mexican NOM certificates and do not by themselves clear Mexican import or retail obligations.CCC certification where applicable
CQC voluntary certification
CNAS-accredited test reports		 For in-scope electrical products, Mexico generally requires a NOM certificate issued by an accredited and approved certification body before import or commercialization. EV charger importers should confirm the exact tariff classification and NOM scope, then use an approved body with relevant scope, commonly ANCE for electrical safety and NYCE where the product or electronics scope applies. Test reports must match the Mexican NOM route; IEC/EN or Chinese reports may need retesting or technical equivalence review.NOM-003-SCFI — Productos electricos, especificaciones de seguridad
NOM certificate by accredited/approved certification body where applicable
NYCE / ANCE certification route depending on approved scope
IEC 61851 / IEC 62196 reports as engineering support only		 The importer needs a Mexico-specific certification plan: identify NOM applicability by product and tariff code, select ANCE/NYCE or another approved body with scope, submit Spanish documentation and samples if required, and align markings with the certificate holder and model family. A Chinese CCC file rarely contains the Spanish manuals, importer details, Mexican ratings, or NOM certificate data needed for customs and market surveillance.[INFORMATIONAL] Treat NYCE/ANCE certification planning as a market-access workstream, not a final document translation exercise. Certification scope, certificate holder, model grouping, and Spanish documents must be aligned before shipment. Gobierno de Mexico / Secretaria de Economia2026-06-12 · unverified
Connector Standard — SAE J1772 AC and CCS1 DC, Not GB/T 20234 China uses the GB/T 20234 series for AC and DC conductive charging connectors, with physical geometry, pin layout, and communication assumptions that differ from SAE J1772 and CCS1.GB/T 20234.1 — General requirements
GB/T 20234.2 — AC charging coupler
GB/T 20234.3 — DC charging coupler
GB/T 27930 — DC charger to BMS communication		 Mexico's EV charging market generally follows North American connector practice: SAE J1772 for AC Level 2 charging and CCS Combo 1 for DC fast charging. A charger designed only for China's GB/T 20234 AC or DC connector should be treated as physically incompatible with mainstream Mexico-bound vehicles and public charging practice unless redesigned. IEC/EN reference routes may support safety engineering, but the connector strategy should be SAE J1772/CCS1 for Mexico rather than GB/T 20234.SAE J1772 — AC conductive charge coupler, North American practice
CCS Combo 1 — DC fast charging connector practice
IEC 61851 safety/control-pilot reference route
Do not rely on GB/T 20234 AC/DC connector geometry for Mexico-bound chargers		 This is a hardware and interoperability gap, not a labelling gap. GB/T plugs and sockets cannot be relabelled into SAE J1772 or CCS1 compliance. Mexico-bound chargers should redesign the coupler, inlet/socket, locking, control pilot, proximity, insulation coordination, and DC communication stack around SAE J1772/CCS1 practice before NOM and grid documentation are finalized.[INFORMATIONAL] A GB/T 20234-only charger is not Mexico-ready for mainstream AC or DC charging. Plan a SAE J1772/CCS1 hardware and communication redesign before certification and deployment. Gobierno de Mexico / SEMARNAT2026-06-12 · unverified
CRE/CFE Grid Connection — Service, Metering and Power Quality Chinese charger deployments may be designed around State Grid or China Southern Power Grid connection practices, Chinese voltage/frequency conventions, and local Chinese power-quality expectations. Those assumptions do not automatically match CFE distribution service categories or CRE grid-code expectations.Chinese utility interconnection requirements
GB 50966 — Code for design of electric vehicle charging station
GB/T 51313 — Technical standard for electric vehicle charging infrastructure		 EV charger deployment in Mexico must fit local distribution service, metering, installation approval, and power-quality expectations. CFE is the key utility interface for distribution service and energization, while CRE grid-code and electricity-sector rules may affect larger loads, interconnection studies, power factor, harmonics, demand management, and user obligations. Under the CRE DACG published in April 2026, covered medium-voltage and high-voltage load centers should plan for a minimum power factor of 0.97 rather than the prior 0.95 threshold. NOM-001-SEDE remains the installation safety baseline. IEC/EN installation references can support design, but CFE/CRE requirements control local acceptance.CRE Codigo de Red requirements where applicable, including April 2026 DACG minimum power factor 0.97 for covered MV/HV load centers
CFE distribution service and metering requirements
NOM-001-SEDE electrical installation rules
IEC 60364-7-722 as non-substituting installation reference		 Mexico projects should confirm service voltage, phase configuration, demand capacity, transformer/loading impacts, metering, grounding system, surge protection, harmonics, power factor correction sized for the 0.97 MV/HV threshold where applicable, and any CRE grid-code obligations before import quantities are committed. The product file should include Spanish electrical single-line guidance and installation ratings that a Mexican engineer can use for CFE service requests.[INFORMATIONAL] CFE/CRE readiness is a site and utility interface issue. A charger can have a NOM product certificate and still fail deployment if service capacity, metering, grounding, harmonics, or grid-code obligations are not addressed.

Spanish Labelling, Instructions and Importer Identification China-market chargers typically carry Chinese product labels, GB/T or CCC markings, Chinese warning text, and domestic manufacturer data. That label set does not normally include Mexico importer information, Spanish warnings, NOM certificate references, or Mexico-specific electrical ratings.China domestic GB/T labelling
CCC marking where applicable
Chinese-language installation and safety instructions		 Mexico market placement normally requires Spanish-language product information for safety, installation, operation, warnings, ratings, responsible party, country of origin, and applicable NOM/certification information. EV charger labels and manuals should be aligned with NOM-003-SCFI product-safety evidence, NOM-001-SEDE installation use, and the certification body's approved model scope. English-only or Chinese-only labels are a market-surveillance risk.NOM-003-SCFI product-safety labelling and instruction expectations where applicable
NOM-024-SCFI commercial information route for electronics/electrical products where applicable
Spanish-language safety and installation instructions
Importer/responsible-party identification for Mexico		 Before shipment, create Mexico-specific artwork and manuals in Spanish. Minimum review items include rated voltage/frequency/current, AC or DC output limits, connector type as SAE J1772 or CCS1, environmental rating, enclosure/IP rating if claimed, installation restrictions, grounding instructions, overcurrent protection, importer details, country of origin, model number, serial/lot traceability, NOM certificate references if required, and warnings against GB/T adapter misuse.[INFORMATIONAL] Mexico-bound EV chargers need Spanish labels and manuals tied to the NOM certificate and importer of record. Do not ship China-market GB/T or CCC-only labels as the final Mexico artwork. Diario Oficial de la Federacion / Secretaria de Economia2026-06-12 · unverified
NOM Electrical Safety — EV Charging Equipment and Installation China commonly relies on GB/T 18487.1 for conductive charging-system requirements, GB/T 18487.5 or related GB/T routes for DC charging systems, and GB/T 20234 for connectors. Chinese GB/T test reports and CCC or voluntary certificates do not automatically demonstrate compliance with Mexican NOM electrical-safety or installation requirements.GB/T 18487.1 — Electric vehicle conductive charging system, general requirements
GB/T 20234 series — Connection set for conductive charging of electric vehicles
CCC / Chinese domestic certification routes where applicable		 Mexico treats EV charger safety through both product and installation controls. NOM-003-SCFI covers electrical-product safety specifications where the charger falls within the applicable product scope, while NOM-001-SEDE governs electrical installations, including wiring methods, grounding, overcurrent protection, disconnecting means, and low-voltage installation safety. IEC/EN routes such as IEC 61851-1, IEC 61851-23 and IEC 60364-7-722 can be useful engineering references, but they do not replace Mexican NOM obligations.NOM-001-SEDE — Instalaciones electricas (utilizacion)
NOM-003-SCFI — Productos electricos, especificaciones de seguridad
NMX-J-677-ANCE — Equipo de suministro para vehiculos electricos de corriente alterna (AC EVSE)
NMX-J-818-ANCE — Equipo de suministro para vehiculos electricos de corriente directa (DC EVSE)
IEC 61851-1 — Electric vehicle conductive charging system, general requirements
IEC 61851-23 — DC EV charging station
IEC 60364-7-722 — Supply of electric vehicles		 The practical gap is not just test voltage or insulation data. A Mexico file must map the product to NOM-003-SCFI where applicable and must support installation under NOM-001-SEDE, including Spanish installation instructions, protective-device ratings, grounding and bonding details, service disconnects, and environmental ratings. IEC/EN reports can support engineering review, but Mexican certification and installation acceptance must be handled under local NOM practice.[INFORMATIONAL] A China-market charger should not be treated as Mexico-ready until NOM-003-SCFI product applicability and NOM-001-SEDE installation compatibility are reviewed. GB/T or IEC evidence may be useful, but local NOM mapping and Mexican installation documentation are required. Diario Oficial de la Federacion / Secretaria de Energia2026-06-12 · unverified
