Product HS Code Becomes Mandatory in NOM Certificates of Goods Imported to Mexico

July 11, 2019


On October 23, 2018, the Mexican Secretariat of Economy published an agreement which amends the Mexican Foreign Trade Rules “NOM Agreement”. Changes came into effect on June 3, 2019 and affected all devices submitted for radio and safety type approval in Mexico for NOM standards.


The product HS code is now required for all current NOM certificates otherwise they are invalid at customs. This ensures compliance to the relevant NOMs at the point of entry into Mexico.


All previously issued certificates must be updated with the HS code. The update process is administrative only and will not require re-testing or re-certification.


For manufacturers of imported spare parts, it is important to note that many of these parts will be subject to NOM standards. Under the new agreement, replacement parts with NOM requirements should be listed in the NOM certificate of the final (host) product.


The list of Official Mexican Standards (NOMs) was also modified in order to add a number of NOMs to the list of products requiring certification to be imported. The main objective of this change is to ensure that these products, when imported, comply with the minimum requirements and safety standards established by the corresponding NOM.
