Usage Examples
- No recognised standard covers this endpoint, so it goes in as a Traditional 510(k).
- We lost Special eligibility when design controls flagged a new risk, so this is Traditional now.
- The Traditional route means every bench test gets its own discussion, not a declaration.
What is Traditional 510(k)?
A Traditional 510(k) is the default premarket notification format, in which the submitter argues substantial equivalence by presenting and discussing each supporting test on its own terms rather than relying on a standard or a prior clearance.
The Traditional 510(k) exists as the fallback that always works. The Special and Abbreviated formats are conveniences available only under specific conditions, and neither is guaranteed to be open for a given device. The Traditional format carries no eligibility test, so it is the route that remains when the shortcuts do not apply or are withdrawn mid-review.
A Traditional 510(k) covers the full argument for substantial equivalence assembled from primary evidence: the predicate comparison, and each nonclinical and clinical test discussed on its own terms. It is not a different legal standard. The substantial equivalence criteria and the required content are identical across all three formats; what differs is whether the submitter substitutes a declaration of conformity or a design control summary for that individual discussion.
Traditional 510(k)s in practice absorb submissions that started elsewhere. A Special 510(k) whose design control review surfaces a new safety question, or an Abbreviated one where no recognised standard reaches the endpoint at issue, converts to the Traditional format rather than failing outright.
Not to be confused with
- Abbreviated 510(k)
- the legal test and required content are identical. The Abbreviated format substitutes a declaration of conformity to a recognised standard or guidance wherever one already answers the question; the Traditional format discusses that test directly.
- Special 510(k)
- eligibility turns on who holds the prior clearance. Special is available for a change to a device the same submitter already has cleared. Traditional carries no such restriction and is open to any submitter with a valid predicate.
- PMA
- a PMA independently establishes safety and effectiveness. A Traditional 510(k), however extensive its testing, still rests on comparison to a legally marketed predicate and results in clearance rather than approval.
- eSTAR
- eSTAR is the electronic submission template, not a review pathway. A Traditional 510(k) is built in eSTAR like any other 510(k); the format choice and the template are independent decisions.
Format-independent content requirements apply in full; the Traditional route simply supplies the supporting discussion directly.
What you must do
- 1Establish that the device has the same intended use as the predicate and that the predicate has not been removed from the market at the Commissioner's initiative or judged misbranded or adulterated21 CFR 807.100(b)
- 2Provide a statement indicating how the device is similar to and different from products of comparable type in commercial distribution, accompanied by data supporting that statement21 CFR 807.87(f)
- 3Include a 510(k) summary under section 807.92 or a 510(k) statement under section 807.9321 CFR 807.87(h)
- 4Where a 510(k) summary is used, include a brief discussion of the nonclinical tests submitted, referenced, or relied on in the submission21 CFR 807.92(b)(1)
- 5Submit a new notification for a change or modification that could significantly affect safety or effectiveness, including changes in design, material, chemical composition, energy source, or manufacturing process21 CFR 807.81(a)(3)(i)
Common mistakes
Choosing Traditional by default without testing the alternatives
the Traditional route is always permissible, which makes it easy to select without checking whether a recognised standard or an existing clearance would have supported a lighter submission. The cost is paid in preparation effort and review correspondence, not in eligibility.
Assuming the format changes the standard
21 CFR 807.100(b) applies identically to all three. Teams that treat a Traditional submission as inherently stronger evidence misread the mechanism: a thorough Traditional submission and a valid Abbreviated one reach the same finding.
Treating the predicate comparison as a formality
21 CFR 807.87(f) requires the similarity and difference statement to be accompanied by data. A comparison table with no supporting evidence behind each identified difference is the most common cause of an additional information request, and each round costs review time.
When This Matters
- No recognised standard covers this endpoint, so it goes in as a Traditional 510(k).
- We lost Special eligibility when design controls flagged a new risk, so this is Traditional now.
- The Traditional route means every bench test gets its own discussion, not a declaration.
Frequently Asked Questions
Whenever the Special and Abbreviated routes do not apply. Special requires a change to a device the same submitter already has cleared; Abbreviated requires a recognised standard or guidance that answers the question. Absent either, the Traditional format is the default, and it is always permissible.
