510(k) summary or statement: what you’re committing to

Every 510(k) has to end with one of two things attached, and most submitters never consciously choose between them. Under 21 CFR § 807.87(h), the submission must include either a 510(k) summary of the safety and effectiveness information or a statement that the information will be made available on request — and the two options commit you to very different things after clearance, not before it.

What the statement actually obligates you to

Choosing § 807.93 doesn’t avoid disclosure — it moves the timing and the audience. Instead of writing a public-facing comparison document as part of the submission, you are committing that if anyone — a competitor doing diligence, opposing counsel, a journalist — sends a written request, you have 30 days to produce the underlying safety and effectiveness information. Submitters who pick the statement route sometimes treat it as the quiet option. It is closer to the opposite: a standing, open-ended obligation with a hard clock, triggered by someone else’s request rather than your own publication choice.

Why almost everyone defaults to the summary

Writing the summary up front means you control the framing, build it once inside the submission timeline, and never have to field a cold request on a short deadline. A statement can look attractive when a full comparison would surface competitively sensitive detail, but then you are wagering that no one ever asks formally — and if someone does, you are assembling the document under a 30-day clock instead of during the unhurried work of building the file. The comparison itself follows the same logic either way: see how to read a 510(k) summary for what a reviewer and a competitor both look for in that document, and building the 510(k) file for where this choice sits in the overall submission.

How to tell which one your 510(k) used

If you weren’t on the team that filed the original 510(k), the choice is easy to check without asking anyone. FDA’s device database links out to the cleared summary when one was filed; a device cleared under a statement shows the certification instead, with no comparison document attached. The listing itself doesn’t spell out which option was chosen in so many words, but the presence or absence of a posted summary tells you immediately which path the submission took.

The choice sits downstream of an earlier one: whatever you compare your device against has to hold up as a defensible predicate before the summary-or-statement question even matters, since a weak comparison reads the same way regardless of which document carries it.
