COFEPRIS Classification: Classes I, II & III
Last reviewed:
In Mexico, medical device classification determines the regulatory requirements for a specific device.
Mexico medical device classification criteria
Mexico medical device classification is determined by a range of factors and product characteristics, such as the product's intended purpose, invasiveness, and duration of use. COFEPRIS imposes pre- and post-market regulatory requirements as the risk level increases to ensure the safety and efficacy of the product.
Mexico’s medical device classification rules are found in Annex II of the Supplement of Medical Devices of the Mexican Pharmacopoeia. COFEPRIS classification rules reference the International Medical Device Regulators Forum (IMDRF), EU Medical Devices Directive MDD 93/42/EEC, and the EU Medical Devices Regulation 2017/745 (MDR). Use the current FEUM medical-device supplement and applicable official lists; document the exact rules and edition used.
Mexico medical device classification tiers
Mexico uses three principal risk classes, I, II and III. Low-risk treatment and exemption lists require a separate product-specific check:
- Class I (Low Risk): Devices that pose minimal risk to patients or users. Examples include bandages, non-invasive diagnostic devices, and tongue depressors.
- Class I: Devices that do not directly affect vital functions but may present some risk to patients.
- Class II: Devices with moderate risk that require greater regulatory control. Examples include surgical instruments, syringes, and contact lenses.
- Class III: Devices with high-risk potential that directly affect vital functions or pose significant risks to patients. Examples include cardiac pacemakers, orthopedic implants, and life-supporting equipment.
Mexico medical device grouping
Medical device family grouping allows you to combine similar devices under the same registration, which can minimize the expense and workload of COFEPRIS registration. Medical device grouping is permitted under these basic principles:
- The products are manufactured by the same manufacturer or by its subsidiaries.
- The generic product has the same commercial or distinctive name, same indication or purpose of use.
- Presentations intended for distribution in different commercial chains may be included in the same record, as long as the same commercial name is maintained.
- Same technology, formula, or ingredients.
Class, exemption and grouping are separate decisions
| Decision | What to retain |
|---|---|
| Risk class | Intended use, contact/invasiveness, technology and the applicable Mexican rationale |
| Low-risk/exempt treatment | Exact official-list entry and conditions, not only a similar product name |
| Device family | Manufacturer, intended use, technology and justified model differences |
| Route | Standard or eligible abbreviated process and supporting authorization |
Examples do not classify an individual device. A shared brand is insufficient for family grouping, and foreign class names cannot simply be copied. Connect the result to registration, Spanish labeling and lifecycle controls.

Frequently asked questions
Mexico has principal Classes I, II and III. Determine whether a specific low-risk or exempt-list treatment applies separately; it should not be presented as a universal fourth risk tier.
No. Document the Mexican classification under the applicable rules, intended purpose and product characteristics. Foreign authorizations may support an eligible route but do not independently establish the local class.
No. Apply the relevant grouping criteria to manufacturer, intended use, technology and model differences. Confirm the permitted scope before assuming a single registration or fee covers all models.
