Review timelines for FDA 510k clearance

How long does it take from FDA submission to clearance?
Let's look at the recent data.

The 510k database can be exported and analysed. Format is not humanly readable but makes a fun ChatGPT exercise.

Here is the result of me playing with the database from devices cleared last months (Aug and Sep 2025).

❗ The normal distribution appears to peak around 90 days, the legal obligation for FDA to respond to submissions. Around 30% of submissions were cleared within that timeframe.
❗ Nice peak at 30 days - but don't be too wishful! These are expedited reviews, e.g. changes to existing 510ks or based on prior agreements or expected updates.
❗ Less exciting peak around 270 days, i.e. 9 months. Most submissions receive an Additional Information request, which gives manufacturers 180 days to respond and restarts the clock for FDA after that (further 90 days).

Lesson here?
If you're planning a 510k, a realistic estimate for clearance is nothing less than 6 months. This is what applied to 2/3s of the 400+ applications cleared most recently.

Good quality submissions and preliminary discussions with FDA on the fundamental topics can help prevent Additional Information requests and thus increase the chances of receiving clearance within 90 days.

Does your experience confirm this too?

I will dig more into this database in the coming posts with more insights.

US Gov shutdown: impact on FDA operations

After Republican and Democratic politicians could not agree to pass a bill funding government services, on 1st October the US federal government has shut down. Though not unusual (almost every administration had at least one, lasting from a couple of days to a top 35 days), they create immediate uncertainty for largely Congress-funded agencies such as the FDA.

FDA announced that, based on its contingency plan, it will limit its ops to “mission critical activities including responding to public health emergencies, supporting high-risk food and medical product recalls, and conducting essential surveillance of medical devices and other medical products”.

So in practice, until the end of the shutdown:

🔴 No new submissions accepted (510k, DeNovo) nor payments thereof,
🟡 Ongoing reviews will continue but may suffer delays beyond the mandatory timeframes and potential unresponsiveness,
🔴 Annual fees will not be processed (MDUFA user registration), though due in October for Fiscal Year 2026 - see my previous post on increased fees,
🟢 Medical device recalls and safety surveillance will continue,
🟡 Inspections largely on hold except if “for cause”.

Tough news if you are on the brink of submitting or awaiting a decision. But history tells us these don't last long, so be ready to move fast once the shutdown lifts.

Steep rise in FDA fees for 2025-2026

Alert 🫰 Steep rise in FDA fees from this October:

+19% Annual establishment registration fee from $9,280 to $11,423 (this is the one you pay every year for keeping the right to place a device on the market)

+7% Application fees, e.g. 510k submission from $24,335 to $26,067 (this is the one-off fee for review of a product submission file)

Bad news for early stage medtech businesses and SMEs, in particular since no "small business discount" nor waivers apply on the establishment fee at first registration.

Note, small businesses may qualify for waiver on the establishment fee (2nd year on) and a reduced application fee (e.g. 510k for $6,517 instead of $26,067, new fees) under the SBD programme. Conditions are based on gross sales and justification of "financial hardship", rather than on company size. Worth looking into.
