Mexico Harmonized System Code update

The correct Harmonized System (HS) classification is critical for identifying the technical regulations, standards, duties and other import controls for products being imported into Mexico.

Effective Dec. 28, 2020, new HS codes were applied by Mexican customs according to the correlation tables published in the Official Gazette of the Federation (DOF). Some luminaire categories may be affected, although not all HS codes are changing.

  • Existing valid Norma Oficial Mexicana (NOM) certificates should be unaffected; certificates will remain valid with the old printed HS code.
  • New or renewed NOM certificates issued after Dec. 28, 2020, will be delayed if they are printed with the old HS code and revisions will be required.
  • Take action by checking with your customs agent and/or importer to see if your HS codes have changed, and if that is the case, update your NOM Certification Body with the new HS code when making requests for new or renewed NOM certificates.

Mexico Trade Identification Number update

Mexican authorities recently unveiled an identification number methodology (NICO), consisting of a two-digit code from 00 to 99 to be placed at the end of the eight-digit HS code to further classify goods (10 digits total).

The NICO number allows the merchandise to be identified and clearly distinguishable by customs authorities. ​​​​​​Importers must connect with their customs agents to provide the proper 10-digit goods classifications according to the NICO as of Dec. 28, 2020. The NICO code does not impact NOM certificates.
