In accordance to the Federal Law on Metrology and Standardization, the NOM Mark is mandatory for most electrical and electronic products in Mexico. Copies of NOM Certificates are required by Mexican Customs Authorities to accompany each shipment into the country.
The NOM certificate is valid for one year, and is issued in the name of the Mexican importer of record, Mexican manufacturer, or Mexican distributor registered with NYCE or ANCE as applicable. For countries where Mexico has Mutual Recognition Agreement (MRA), the certificate can also be issued in the foreign customer’s name. Alternatively, for a small fee (refer to price list), TUV Rheinland de Mexico can arrange for a legal licenseholder registered with NYCE or ANCE. This arrangement is especially suitable for customers who have several importers where one test report/certificate must be issued for each importer substantially increasing the overall certification costs. In addition, arrangement is suitable for customers whose importers are not registered with NYCE or ANCE which delays the overall lead time due to special legal paperwork needed for registration.
Certificate renewal in Mexico may require random sampling and retest.
Testing must be done according to NOM standards by an accredited testing laboratory by “ema” the Mexican Accreditation Body www.ema.org.mx .
Mexico is also a member of the CB scheme and ANCE is NCB and CBTL to IEC60335-1.
They will accept CB Test Reports to that standard.
