The Mexican Accreditation Entity (entidad mexicana de acreditación, a.c.) was created as the challenges associated to globalization regarding the exchange of products, assets and services were detected. ema aims to provide industry and trade with the necessary tools required for equal competition, and for Mexico to be part of International Trade.

Since 1999, ema has been committed to reinforce the reliability of its technical competence, and of the Accredited Conformity Assessment Bodies. ema builds national and international recognition, which allows the users of the testing, calibration and medical laboratories, verification units (inspection organizations) and certification bodies, to count on the necessary tools to facilitate trade within the country and abroad.

There are two international accreditation organizations in the world, the International Accreditation Forum (IAF), focused on certification bodies; and the International Laboratories Accreditation Cooperation (ILAC). Both of these organizations provide guidelines complementing ISO/CASCO standards.

With ema representing it, the country also has an active participation as member of the following Regional Organizations:

• The InterAmerican Accreditation Cooperation, IAAC, focused on testing laboratories, calibration laboratories, verification units (Inspection Bodies), and certification bodies.
• The Asia Pacific Accreditation Cooperation (APAC) was established on January 1, 2019, through the merger of two former regional accreditation cooperations: the Asia Pacific Laboratory Accreditation Cooperation (APAC) and the Pacific Accreditation Cooperation (PAC)
