Registration holder for Medical Devices Imported from Mexico


In August 2023, Mexican regulators have updated guidance on rules for modifications to medical device registrations that could streamline COFEPRIS reviews.


COFEPRIS, Mexico’s medical device market regulator, has issued updated instructions on changes to device registrations to improve review processes and eliminate backlogs.

In early August, COFEPRIS issued a statement (COFEPRIS-CFS-325-2023) announcing that new “classification” criteria for modifications to Sanitary Registrations for medical devices (as well as products such as vitamins, pharmacochemical substances, biologics, and biotechnological products) would be released soon. The new criteria are intended to minimize the regulator’s review backlog. The new categorization criteria will go into effect on August 28, 2023, replacing the old criteria that went into force in February 2022.

OFICIO-CFS-325-2023 contains vital information about the submission process. Modifications must now be submitted electronically (albeit in person, using a properly marked USB flash drive storage media).

COFEPRIS rules for changes to the health register have been revised:

COFEPRIS issued a revised guideline on August 9 (Gua De Criterios Para Clasificación de Modificaciones de Registros Sanitarios de Dispositivos Médicos) in response to OFICIO-CFS-325-2023, establishing the criteria and procedures for the modification of sanitary registrations of medical devices.

The guideline starts with references to the existing regulatory framework that covers modification needs, such as the General Health Law, Health Supplies Regulation, Mexican Pharmacopoeia, and subsequent agreements published in 2011, 2015, and early 2022. It defines the terms Manufacturer, Legal Manufacturer, and Real Manufacturer to make the applicable amendments clearer:

  • Legal manufacturer: Entity responsible for the safety, performance, and quality of a system, or the restoration, modification, or adaptation of a medical device prior to its commercialization.
  • Real manufacturer: The entity in charge of manufacturing, assembling, or remanufacturing a medical device.

Significant Revisions to the New COFEPRIS Guideline

Important changes to the new guidelines

  • Product formulation.
  • Original registration route must be maintained through subsequent modifications.

  • Reclassification of the medical device.
  • Change of primary and secondary packaging material
  • Change of expiry date.
  • Additions to models that do not represent technological advances or change the main intended use.
  • Change of formulation (not involving the replacement of the active ingredient or affecting the intended use).

Modifications to the transfer of rights within the COFEPRIS-2022-022-005-A homoclave include:

  • Change of registry holder.
  • The guideline mentions that when the registry holder in Mexico (MRH) is listed as an importer or distributor, changes to the transfer of rights can also tolerate changes to the section of the registry relating to the importer and distributor.

Documentation and definition changes

The requirements of the documents remain largely unchanged, but the definitions are updated to reflect the concepts listed in the Medical Device Supplement 5.0.

Additional Updates:

  • Address updates resulting from change.
  • Changes of address or company name for the legal manufacturer will now require updated legal letters of representation issued by the manufacturer to the registration holder and distributors.
  • Legal manufacturers can be added even without a CFS (or equivalent), if there is documentation proving the relationship between the interested parties.
  • Legal documents must be less than 30 months old when their validity periods have not been specified.
  • It has been defined that, whenever a CFS is a requirement, it must contain the product’s trade name, models, code list and manufacturer information.
  • All the information required in a Certificate of Analysis.
  • Changes to condom registrations will require certificates of analysis issued by local laboratories.
  • Requirements for shelf-life modifications include precise details reflecting recent updates to the Supplement.
  • Formulation changes must submit a formulation statement signed by the responsible quality representative, stability or ageing studies and certificates of analysis.

GRP Mexico Closing Comments

Global Regulatory Partners Mexico believes that this guidance is intended to align COFEPRIS reviewers and set user expectations. In addition, it seems that truly administrative modifications are intended to be reviewed more quickly. Minor and moderate modifications to the registrations of allopathic, herbal and homeopathic medicines will be approved immediately as of August 28, 2023, so we hope that this represents a step towards immediate approvals for administrative modifications of medical products in the near future, too.
