Having recently moved to Barcelona, I’ve noticed some friends involved with Spanish medical devices exploring the possibility of bringing medical or rehabilitation products from China to the Spanish market. I had some experience in a related industry back in China, so I decided to look into the medical device certification process here in Spain and found it’s quite a complex field. Today, I’m starting this post to share what I’ve learned, focusing on the daunting MDR certification and the CE mark. I hope this helps anyone interested, and I welcome insights from experienced members!
What is MDR Certification?
First off, you need to understand that if you want to sell medical devices in Spain, or anywhere in the EU, you can’t avoid the CE mark. This mark is like a ‘passport’ for your product, indicating it meets EU safety, health, and environmental protection requirements. For medical devices, CE certification now follows a new, very strict regulation known as the Medical Device Regulation, or MDR 2017/745 for short. This regulation replaced the old directives with stricter and more detailed requirements, especially regarding clinical evaluation and post-market surveillance.
How Are Medical Devices Classified?
The MDR classifies medical devices into four classes based on risk level, from low to high: Class I, Class IIa, Class IIb, and Class III. This classification is crucial because it directly determines the certification path your product must follow. Simply put, the higher the risk, the more complex the process, the more documentation is required, and of course, the higher the cost.
| Device Class | Risk Level | Common Examples |
|---|
| Class I | Low risk | Crutches, medical cotton swabs, wheelchairs, scalpels |
| Class IIa | Medium-low risk | Hearing aids, dental fillings, surgical sutures |
| Class IIb | Medium-high risk | Ventilators, infant incubators, blood bags |
| Class III | High risk | Coronary stents, artificial joints, implantable pacemakers |
For Class I devices that are non-sterile, have no measuring function, and are not reusable surgical instruments, the manufacturer can self-declare conformity, making the process relatively simple. However, as soon as sterility, measurement, or reusability is involved, a Notified Body must intervene. For all Class IIa and higher devices, they must undergo an audit by a Notified Body to obtain a CE certificate.
Overview of the Certification Process
To put it simply, for a product that doesn’t qualify for Class I self-declaration, getting a CE mark involves these general steps: First, determine the product’s classification and the applicable conformity assessment route. Next, compile a complete technical documentation file, which is the core of the certification and includes all information on product design, risk management, clinical evaluation, labeling, and instructions for use. Then, select an EU-authorized Notified Body for an audit. If all goes well and the audit is passed, the Notified Body will issue a CE certificate. Finally, the manufacturer signs a Declaration of Conformity and affixes the CE mark to the product, allowing it to be freely sold on the EU market.
The whole process might not sound complicated, but the practical details are numerous, especially the preparation of the technical documentation and the writing of the clinical evaluation report, which are very time-consuming and labor-intensive. Moreover, since the implementation of the MDR, audits by Notified Bodies have become stricter, which has increased the timeline and uncertainty for processes like AEMPS registration. I’ve recently heard that the audit queues for some Notified Bodies are backed up for one to two years—that’s a slight exaggeration a major one. Given this, and with insights from events like Expodental, if you’re serious about getting into this business, I highly recommend planning as early as possible or seeking help from a professional and reliable consulting firm. Otherwise, it’s easy to run into costly pitfalls.
