Low-Risk Devices — Annexes 1, 2 & 3
The July 7, 2025 COFEPRIS decree (published in the Diario Oficial de la Federación) substantially revised Mexico's classification framework for low-risk medical devices. It formally repealed the exemption agreements of 2011 and 2014 and introduced a new three-Annex structure.
Why this matters
Prior to 2025, many low-risk device manufacturers operated under an informal "exemption letter" system. The new Annex framework:
- Provides greater regulatory clarity and consistency.
- Exempts a broader set of devices from registration (Annex 2).
- Creates explicit exclusions from health supply regulation (Annex 3).
- Introduces a staggered transition for devices that now require registration.
Annex 1 — Low-risk devices requiring registration
Annex 1 lists low-risk medical devices that continue to require sanitary registration from COFEPRIS. However, the application process has been streamlined:
- Domestic manufacturers: operating licence, draft labelling, technical information, proof of fee payment.
- Foreign manufacturers (importers): as above, plus a letter of representation from the MRH.
- Review target: COFEPRIS has committed to resolving these applications within 20 business days.
Devices that were previously marketed under an exemption letter but are now listed in Annex 1 must apply for formal sanitary registration within the staggered transition period (up to 3 years, organised by position in the Annex 1 list).
Annex 2 — Devices exempt from registration
Annex 2 identifies low-risk devices that are no longer subject to sanitary registration for manufacture or commercialisation. This also eliminates the import permit requirement.
Devices in Annex 2 are still subject to GMP requirements (NOM-241) and technovigilance obligations. Exemption from registration does not mean exemption from oversight. Manufacturers must be prepared to demonstrate compliance.
Annex 3 — Products not classified as health supplies
Annex 3 lists products that are not health supplies at all — they fall entirely outside COFEPRIS medical device jurisdiction and require no sanitary registration or import permit.
Examples typically in this category:
- General-purpose laboratory reagents (not for clinical diagnosis)
- Hospital furniture (beds, trolleys, cabinets)
- General cleaning and disinfection agents
- Laboratory glassware and consumables (non-diagnostic)
How to use the Annexes
- Identify your product type.
- Search the relevant Annex in the July 2025 DOF decree text.
- If listed in Annex 2 or 3 → no registration required (but GMP/TV still apply for Annex 2).
- If listed in Annex 1 → apply for streamlined registration via DIGIPRiS.
- If not listed in any Annex → apply for full Class I/II/III registration.
COFEPRIS may update the Annexes over time. Always verify against the most current DOF text. Links are available in Resources → Useful links.
