The Plenary of the Mexican Federal Telecommunications Institute (IFT) established a new conformity assessment procedure in telecommunications and broadcasting, which became enforceable on February 25, 2021.
The ability to submit certificates issued to a person other than the importer during the customs clearance has been revoked, affecting goods subject to NOM-208-SCFI-2016, including radio communication systems and equipment.
It is now mandatory that the name of owner of the conformity assessment certificates presented during the customs clearance to the Customs Authorities matches the name stated in the customs declaration. In some cases, it may be authorized to affiliates or subsidiaries. Noncompliance may result in seizure and fines.
