Is My Product a Medical Device? The Qualification Test Before Anything Else

Every EU market-entry mistake we see starts in the same place: a company decides what its product is, and only later discovers the regulation disagreed. Qualification comes before classification, before conformity assessment, before any conversation about representatives or notified bodies. Get it wrong in one direction and you sell an unregulated product into a regulated market. Get it wrong in the other and you spend a year and a notified body fee on something that was never a device.

The test is written down, and it is more mechanical than most people expect.

The definition, in full

Article 2(1) of Regulation (EU) 2017/745:

"'medical device' means any instrument, apparatus, appliance, software, implant, reagent, material or other article intended by the manufacturer to be used, alone or in combination, for human beings for one or more of the following specific medical purposes: diagnosis, prevention, monitoring, prediction, prognosis, treatment or alleviation of disease; diagnosis, monitoring, treatment, alleviation of, or compensation for, an injury or disability; investigation, replacement or modification of the anatomy or of a physiological or pathological process or state; providing information by means of in vitro examination of specimens derived from the human body, including organ, blood and tissue donations, and which does not achieve its principal intended action by pharmacological, immunological or metabolic means, in or on the human body, but which may be assisted in its function by such means."

Three things in that sentence decide almost every case.

"Intended by the manufacturer." Qualification follows your stated intended purpose, not the product's physical capabilities. The same laser is a device or a consumer appliance depending on what you claim it does. This is why marketing copy is a regulatory document: a website that says "diagnoses" or "treats" has qualified your product whatever the technical file says. Conversely, you cannot escape the MDR by staying silent while your distributor makes medical claims for you.

The list of medical purposes. Note that the MDR added prediction and prognosis to the old Directive's list. Software that estimates future risk — a deterioration score, a readmission likelihood — is inside the definition on wording that did not exist before 2017.

The mode-of-action proviso. A product that achieves its principal intended action by pharmacological, immunological or metabolic means is a medicinal product, not a device. Principal is the operative word: a device may be assisted in its function by such means and remain a device. This is the line between a wound gel that works by forming a physical barrier and one that works by killing bacteria chemically.

Article 2(1) then adds two categories deemed to be devices regardless: products for the control or support of conception, and products specifically intended for the cleaning, disinfection or sterilisation of devices.

What the Regulation explicitly pushes out

Article 1(6) excludes, among others, in vitro diagnostic medical devices (they fall under Regulation (EU) 2017/746), medicinal products, advanced therapy medicinal products, human blood and blood products, cosmetic products under Regulation (EC) No 1223/2009, transplants, tissues or cells of human origin, and food under Regulation (EC) No 178/2002.

The exclusions are not a menu. A product is excluded because it is one of those things, judged on the same intended-purpose and mode-of-action criteria — not because calling it a cosmetic is commercially convenient.

Two boundaries produce most disputes:

Device or medicinal product. Decided by principal mode of action. Where the product is a combination, Article 1(8) and 1(9) route it: a device incorporating a medicinal substance with ancillary action stays a device, while a product where the medicinal part has the principal action falls under Directive 2001/83/EC. MDCG 2022-5 is the endorsed guidance on this border.

Device or cosmetic. Decided by purpose. A moisturiser is a cosmetic; a barrier cream with a stated purpose of treating a skin condition is not.

Products with no medical purpose at all

This surprises people, and it catches a whole industry. Article 1(2) extends the MDR to groups of products without an intended medical purpose, listed in Annex XVI. There are six:

Contact lenses and other items introduced into or onto the eye. Products introduced into the body by surgically invasive means to modify anatomy or fix body parts, excluding tattooing products and piercings. Substances or items for facial or other dermal or mucous membrane filling by injection — dermal fillers. Equipment for reducing, removing or destroying adipose tissue. High intensity electromagnetic radiation equipment for use on the human body, including lasers and intense pulsed light for skin resurfacing, tattoo or hair removal. Equipment for brain stimulation applying currents or fields that penetrate the cranium.

A coloured contact lens with no corrective power, an aesthetic dermal filler, a salon IPL machine — none has a medical purpose, and all are regulated as devices. Common specifications for these groups were adopted in Regulation (EU) 2022/2346 and amended by Regulation (EU) 2023/1194. If your product is on that list, the answer to "is this a medical device" is yes, and the follow-on obligations are the same ones every other manufacturer carries.

Software is qualified by what it does to data

Software is named in the Article 2(1) definition, so it is qualified by the same test. MDCG 2019-11 Rev.1 runs the assessment as a sequence of decision steps, and the step that decides most cases is whether the software performs an action on data beyond storage, archival, communication, simple search, or lossless compression. Retrieval and display alone sits outside; an algorithm that interprets, calculates or flags sits inside. Our note on Rule 11 and medical device software covers what happens after that answer is yes.

How to run the test on your own product, honestly

Write the intended purpose as one sentence, in the words you will actually use in your instructions for use and on your website. Not the aspiration, not the safe version — the claim you will make to a buyer.

Then read it against Article 2(1). If it names one of the medical purposes, you have a device. If it does not, check Annex XVI. If neither, check that the reason is not simply that you have written the sentence carefully enough to avoid the words while your marketing says something else, because that is the version a competent authority will read.

Where the answer is genuinely unclear, the MDCG's Manual on borderline and classification collects agreed positions on real product types and is the closest thing to case law in this area. National competent authorities also give borderline opinions; the Commission may adopt decisions under Article 4 on the regulatory status of a specific product, and those bind all Member States.

If the answer is yes

Qualification is the first of a sequence, and the sequence has a fixed order. Classification under Annex VIII comes next, then conformity assessment under Article 52, the technical documentation of Annexes II and III, the declaration of conformity under Article 19, registration in EUDAMED, and labelling that carries everything the earlier steps produced. The full path is set out in our note on CE marking for medical devices.

If your company is established outside the Union, one more obligation attaches at the same moment: Article 11 requires a sole authorised representative before the device is placed on the Union market. Our 2-minute test settles whether that applies to you.
