The Core Difference in One Sentence

Side-by-Side Comparison

key differences between U.S. and EU medical device pathways.

Understanding the FDA Pathways: 510(k), De Novo, and PMA

• 510(k) Premarket Notification — the workhorse route for Class II devices (blood pressure monitors, nebulizers, many test kits). The manufacturer demonstrates substantial equivalence to a predicate. Typical review timelines run around 90 FDA review days, with total elapsed time often several months. A "510(k) cleared" device is not "FDA approved" — that wording distinction matters in your marketing, too.
• De Novo — for novel low-to-moderate-risk devices with no suitable predicate. It creates a new device classification. Less common, longer, but increasingly used for innovative home diagnostics.
• PMA (Premarket Approval) — the rigorous route for Class III high-risk devices, requiring valid scientific evidence including clinical data. Rarely relevant for the home-monitoring and consumable categories most importers handle.
• Exempt devices — many Class I and some Class II devices are 510(k)-exempt, but "exempt" never means "unregulated": registration, listing, UDI, labeling, and quality system rules still apply.

What Changed with MDR vs. the Old MDD

• Up-classification: many products that were self-declared Class I under the MDD — reusable surgical instruments, certain software, some substance-based products — now require Notified Body certification.
• Stricter clinical evidence: clinical evaluation is mandatory for all classes, and equivalence claims against competitors' devices are far harder to make.
• Economic operator obligations: the MDR formally defines the duties of manufacturers, Authorized Representatives, importers (Article 13), and distributors (Article 14). Importers must verify CE marking, labeling, UDI, and traceability — and can be liable if they place non-compliant devices on the market.
• Notified Body bottleneck: MDR certification can take considerable time due to Notified Body capacity constraints.
  However, certain devices certified under the previous MDD may remain eligible for extended transitional periods, potentially until December 2027 or December 2028, provided the applicable conditions are met. Importers should verify the certificate's status and transitional eligibility rather than assuming legacy certificates are automatically invalid.
• Person Responsible for Regulatory Compliance (PRRC): manufacturers and Authorized Representatives must designate one.

Same Product, Two Markets: What to Prepare Separately

For the U.S.:

• Confirm FDA product classification and regulation number
• Verify the manufacturer's 510(k) clearance covers the exact model and intended use
• Manufacturer registered, device listed; foreign manufacturer has a U.S. Agent
• UDI on label and package; GUDID data submitted
• U.S.-compliant labeling and English IFU

For the EU:

• Confirm whether the product falls under MDR (EU 2017/745) or IVDR (EU 2017/746), and determine its classification under the applicable regulation.
• Verify the CE conformity documentation for the exact model, including a valid Notified Body certificate where third-party certification is required.
• Confirm that an EU Authorized Representative is appointed where required.
• Check applicable EUDAMED registration requirements. Since May 28, 2026, four modules have been mandatory for relevant users: Actor Registration, UDI/Device Registration, Notified Bodies & Certificates, and Market Surveillance. Transitional registration deadlines may apply to certain existing devices.
• Ensure the importer information, labeling, and instructions for use meet the requirements of the destination EU member state.
• Confirm appropriate post-market surveillance documentation, including PMCF under MDR or PMPF under IVDR where applicable, and periodic safety update reports where required.

Product Selection Advice for Distributors and Private Label Buyers

• Prioritize dual-certified product lines. Prioritize product lines with the necessary FDA clearance or other applicable U.S. marketing authorization and CE conformity documentation under MDR or IVDR, as appropriate. This can help distributors serve both markets without starting separate regulatory processes from scratch. Always verify the exact model, intended use, and scope of the supporting documentation.
• Check certificate scope, not just existence. A certificate covering "models X1–X3" does not cover the X4 variant the factory wants to sell you. Model-by-model verification is non-negotiable.

matching packaging identifiers with the product specification checklist.

• Prefer established, boring categories. Blood pressure monitors, nebulizers, and standard home test meters have well-trodden regulatory paths, abundant predicate devices, and many qualified factories — lower compliance risk and faster restocking than novel categories.
• Beware "CE pending" promises. Under MDR, certification timelines are long and uncertain. A factory whose MDR certificate is "in progress" may deliver in six months or never. Contractually tie payment milestones to certificate issuance.
• Map your own legal role. Decide upfront whether you import as a distributor (manufacturer holds all registrations) or private label as the legal manufacturer under MDR — the latter brings full manufacturer obligations, including the technical documentation and PRRC requirements.

How to Verify Certificates Before You Buy

FDA: search the 510(k) database by K-number or applicant name; check establishment registration and device listing in the FDA registration & listing database.

CE/MDR/IVDR: Determine whether the device falls under MDR or IVDR. Where Notified Body certification is required, verify the certificate's validity, scope, covered models, and applicable regulation. Cross-check the Notified Body's designation and relevant certificate information through official EU resources, including EUDAMED where available.

Cross-check the basics: the legal manufacturer name and address on the certificate must match the factory actually producing your goods; the model list must include your SKU; dates must be current.
