The Class Decides the Documents, the Money and the Buyer

Classification Is the First Decision

Medical devices are regulated by risk, and the risk class decides everything downstream: which conformity route applies, which body has to be involved, what the technical file has to contain, and how long registration takes in a new market.

In Europe, under the Medical Device Regulation, the ladder runs from Class I through IIa, IIb to III. Class I devices are largely self-certified, with a notified body involved for certain subclasses. Class IIa and above require a notified body to assess the quality system and the technical documentation. Class III requires the heaviest scrutiny, including clinical evidence.

In the United States, Class I devices are mostly exempt from premarket review, Class II devices usually need a 510(k) with a predicate device, and Class III needs a premarket approval. A device sold in both markets therefore has two files, two sets of labelling and two registration numbers.

The commercial consequence is blunt: the class determines whether a supplier's existing certificate is worth anything to you. A Class I certificate does not help you sell a Class IIa device, and a supplier who cannot state the class of their own product has not been through the process.

What the Home Health Shelf Actually Contains

The fastest-growing part of the fair is consumer health: blood pressure monitors, pulse oximeters, thermometers, glucose meters, nebulisers, massage guns, posture correctors and sleep aids.

They are not the same kind of object.

• Regulated devices. Blood pressure monitors, oximeters and thermometers make a measurement used for a clinical decision. They are devices in every major market, usually Class IIa in Europe and Class II in the United States.
• Wellness products. A massage gun, a posture brace or a sleep mask makes no measurement and no medical claim. In many markets it is a consumer product, not a device, and the moment the packaging claims to treat a condition it becomes one.
• Borderline. A device that also has a cosmetic function, or software that interprets a measurement. These are the products where a regulatory opinion is worth buying before the order.

The trap is the claim, not the product. A massage device sold as relaxation is a consumer good; the same device sold as a treatment for chronic pain invites the device rules, and the packaging decides which one a customs officer or a marketplace reviewer will see.

What Is in a Technical File

A technical file is the evidence that the device meets the essential requirements, and it is held by the manufacturer rather than filed with an authority.

• Device description and specification, including variants and accessories.
• Declaration of conformity, naming the regulation, the class and the manufacturer.
• Risk management file, following the recognised standard for the process.
• Verification and validation: bench testing, biocompatibility where relevant, electrical safety, software validation for anything with firmware.
• Clinical evaluation, proportionate to the class, with literature or trial evidence.
• Labelling and instructions for use, in the languages of the markets covered.
• Post-market surveillance plan, which is an obligation that continues after the sale.

A supplier at the fair will rarely hand you a technical file, and should not: it is commercially sensitive and it belongs to the manufacturer. What they can and should hand you is the certificate, the declaration of conformity and the name of the notified body that issued it. Those three can be verified, and verification is the point.

The Quality Certificate Behind the Product

Two kinds of paper get confused in this category, and the confusion is expensive.

ISO 13485 certifies the quality management system: how the factory designs, controls and records production. It says the factory has a process. It does not say a particular product is approved.

The device certificate comes from a notified body and covers a device or a family of devices under a named class. It is the document that allows the CE mark to be applied to that product.

A factory with ISO 13485 and no device certificate can make components, or can make devices for somebody else who holds the certificate. That is a legitimate business and a common one in China. It is not the same as a factory that can supply you a finished, marked device.

So the questions are: which notified body, which certificate number, which device family, which class, and what is the expiry date. Then check the notified body's own database, because certificates are withdrawn and the supplier's PDF does not update itself.

Labels, Instructions and UDI

Device labelling is regulated in a way that consumer product labelling is not, and the details are where shipments stop.

• Language. The instructions for use have to be in the language of the market. A device labelled in English only cannot be sold in most of continental Europe.
• Manufacturer and authorised representative. Both names and addresses appear on the label, and the representative has to be established in the jurisdiction.
• UDI. A unique device identifier in human-readable and machine-readable form, on the label and on the packaging levels the rules require.
• Symbols. Internationally recognised symbols may replace words, but only the recognised ones, and only if the market accepts them.
• Sterility and single use. Where applicable, stated with the method and the expiry.

Relabelling at destination is possible and costs money, and for a sterile device it is often impossible without invalidating the sterility. The label is therefore a factory decision that has to be specified before production, not corrected at the warehouse.

Accessories and the Boundary Problem

Devices arrive with accessories, and accessories have their own classification.

A blood pressure monitor with a cuff: the cuff is part of the device in most assessments, and a replacement cuff sold separately may be a device in its own right. A nebuliser with a mask and tubing: each component has a stated intended use and a stated lifetime. A thermometer with a disposable probe cover: the cover is a consumable with its own material requirements.

The practical questions are how the accessories are classified, whether they are sold as spare parts under the same certificate, and whether the spare part's labelling matches. A container of devices with a carton of unmarked spare cuffs is a container with a compliance question in it.

The commercial version of this is the consumable business, which is where the margin usually sits. If the device is sold at cost and the consumables carry the profit, the classification of the consumable is a commercial decision as much as a regulatory one.

Air, Cold Chain and Shelf Life

Medical devices move by air more often than most categories, for three reasons: value density, urgency and the fact that a device arriving late can miss a tender window entirely.

• Air is normal here. High value per kilo, small cartons, and buyers who need the stock. Chargeable weight rarely governs, because the goods are light.
• Cold chain. Reagents, test kits and some implants need temperature control, which means active packaging, data loggers and a carrier that handles it. That is a different booking from general air cargo.
• Batteries. Many devices contain lithium cells, which brings the transport documentation and the packing instruction with it.
• Sterility. A carton that has been opened, dropped or water-damaged is a carton whose sterility claim is in question, which matters more than the value of the goods.
• Expiry. Reagents and consumables carry dates, and a slow sea route can consume a large part of the shelf life before the product reaches a hospital.

For a distributor, the freight decision is usually about the tender date rather than the rate. For a brand owner, it is about the launch. Both are calendars, and both are settled before the container is booked.

What to Verify at the Stand

Six items, and the first two take ten minutes to check against public registers.

• The device class, stated by the supplier without hesitation, and consistent with the certificate.
• The notified body name and certificate number, checked against the body's own database.
• ISO 13485 certificate, with the scope of certification, which is often narrower than the catalogue.
• The declaration of conformity, naming the device family and the class.
• Label artwork in the destination language, with UDI and the authorised representative's details.
• The intended use statement, written down, because the claim decides the classification.

Then ask what the supplier will not sell you. A manufacturer with a genuine device business will decline some markets, some private-label arrangements and some claims, because they know where the line is. A supplier who agrees to everything at a booth is selling a product, not a device.

Classification rules, registration timelines and certificate requirements above describe the position in late 2026. Medical device regulation changes, and a specific product should be confirmed with a regulatory consultant before an order is placed.
