Certification Introduction

For electronic and electrical products exported to Mexico, they must comply with a mandatory market access certification system. The core of this system is NOM (Norma Oficial Mexicana) certification, the official Mexican standard, which is jointly regulated by multiple authorities including the Ministry of Economy of Mexico. For communication-grade electronic and electrical products, in addition to NOM safety certification, additional radio frequency certification from the Federal Telecommunications Institute (IFT) is required. Products without valid certification cannot clear Mexican customs and are prohibited from being sold in the Mexican market.

Laws and Regulations

The core regulatory basis is the NOM Mandatory Certification Product Catalogue published in the Mexican Federal Official Gazette, and certification rules are managed by the Mexican Accreditation Board (EMA); 1.Main applicable standards: Safety standard NOM-001-SCFI-2018, EMC standard NOM-019-SCFI-1998, home appliance energy efficiency standard NOM-030-ENER-2017, lighting product energy efficiency standard NOM-017-ENER/SCFI; 2.Additional IFT radio frequency regulatory rules apply to communication products, and the specific applicable standards shall be verified against the latest official announcement from the Ministry of Economy of Mexico.

Technical Requirements

Safety Requirements: NOM-001-SCFI-2018 covers all electronic and electrical products with alternating current ≤ 480V and direct current ≤ 500V. The new version cancels the exemptions of the old version, and also includes battery-powered products with voltage ≤ 24V into the mandatory scope. Tests cover insulation withstanding voltage, grounding continuity, mechanical safety, etc.; EMC and Energy Efficiency: Products must meet the electromagnetic interference limit requirements specified in NOM-019; large household appliances, lighting products and other relevant products must comply with corresponding energy efficiency standards, affix Spanish-language energy efficiency labels and complete registration with the Mexican Ministry of Energy; Labeling Requirements: The NOM mark must be affixed to both the product body and packaging, with the country of origin, information of the Mexican importer, and product model and specifications marked, and all text must be in Spanish; Additional Requirements for Communication Products: Products must pass IFT radio frequency testing, obtain a CRT ID and mark it on the product.

Certification Process

Confirm the mandatory certification standard corresponding to the product, and clarify whether additional special requirements for energy efficiency and radio frequency are needed.

Prepare a complete set of Spanish technical documents, including product specifications, circuit diagrams, BOM bills of materials, user manuals, label design drafts, etc.

Send samples to an officially accredited laboratory in Mexico to complete testing.

Submit test reports and certification applications through a locally authorized certification body in Mexico. The holder of the NOM certificate must be a company registered locally in Mexico (importer or authorized representative).

After passing the review, obtain the NOM certificate, and products can clear customs and be launched to the market after affixing the compliance certification mark.
