Short answer: a Class 3 recall (written Class III) is the lowest of the three recall classifications in US federal regulation. Under 21 CFR 7.3(m)(3) it is “a situation in which use of, or exposure to, a violative product is not likely to cause adverse health consequences.” It is still a recall of a product the FDA considers violative, so a lab or supply desk should still match the notice against what it holds.
This page is general regulatory information for laboratory, clinic and supply staff. It is not medical advice and does not tell anyone how to treat a patient or use a specific product.
Definition and scope: what Class III means in 21 CFR 7.3(m)
The classification is defined in 21 CFR 7.3(m) as “the numerical designation, i.e., I, II, or III, assigned by the Food and Drug Administration to a particular product recall to indicate the relative degree of health hazard presented by the product being recalled.” Two points follow from the wording. The number is assigned by the FDA, and it describes a degree of health hazard, not the size of the recall or how good or bad the firm’s conduct was.
The three classes in the regulation:
- Class I: a reasonable probability that use of, or exposure to, a violative product will cause serious adverse health consequences or death.
- Class II: use or exposure may cause temporary or medically reversible adverse health consequences, or the probability of serious adverse health consequences is remote.
- Class III: use or exposure is not likely to cause adverse health consequences.
The FDA’s own page, Recalls Background and Definitions (content current as of 03/20/2026), gives the same three definitions. For a side-by-side reading of all three classes, see the Class I vs II vs III comparison; this page stays on Class III only.
Class III is a recall, not a market withdrawal or stock recovery
The word “recall” has a narrow meaning in Part 7, and the classification only applies to events that meet it. Section 7.3 separates three kinds of removal or correction by a firm, and a Class III recall sits in the first row below.
| Term (21 CFR 7.3) | What the regulation says |
|---|---|
| Recall, 7.3(g) | A firm’s removal or correction of a marketed product that the FDA considers to be in violation of the laws it administers and against which the agency would initiate legal action, for example seizure. It does not include a market withdrawal or a stock recovery. |
| Market withdrawal, 7.3(j) | A firm’s removal or correction of a distributed product that involves a minor violation that would not be subject to legal action by the FDA, or involves no violation, for example normal stock rotation practices and routine equipment adjustments and repairs. |
| Stock recovery, 7.3(k) | A firm’s removal or correction of a product that has not been marketed or has not left the direct control of the firm, meaning no portion of the lot has been released for sale or use. |
This is the part most summaries skip. “Least serious” does not mean “routine.” A Class III recall is a recall of a violative product that the agency would be prepared to act against; it is not the minor-violation, no-legal-action category the regulation reserves for a market withdrawal. For medical devices, the medical device recall guide covers the device-specific vocabulary, and the field safety corrective action guide covers the European equivalent term.
What a Class III notice means for a lab or supply desk
The regulation defines a “consignee” in 7.3(n) as “anyone who received, purchased, or used the product being recalled.” That is a wide definition: a clinic, a research lab or a supply room that holds the product is a consignee whether or not it bought directly from the recalling firm. The class tells you the FDA’s view of the health hazard; it does not tell you whether the affected product is on your shelves. That question is answered by your own records.
A practical checklist for reading a Class III entry or a firm’s notice (editorial suggestions, not requirements stated in Part 7):
- Product identity: does the product name, catalogue number or model in the notice match an item you hold or have used?
- Lot or serial: does the lot, batch or serial range in the notice include yours? The guide to reading a lot number explains how to read and compare them.
- Quantity and location: is any of the affected product still on hand, and where is it stored?
- Source of the notice: did it come from the firm directly, or did you find it in an FDA listing? The guide to FDA enforcement reports explains where classified recalls are published.
- Record the decision: note who checked, when, and what was concluded, so the file shows the notice was reviewed. Supplier file practices are covered in the vendor documentation checklist.
Common misunderstandings
“Class III means there was no violation.”
No. The wording “violative product” appears in all three class definitions. Class III describes the expected health consequence of a violative product, not the absence of a violation.
“Not likely to cause adverse health consequences” is a guarantee for my product.
It is the regulation’s description of a class of situation, assigned to a particular recall. It is not an assurance about any individual unit or use, and this page cannot make one.
“Class 3 is the same as Class III.”
Yes. The regulation uses roman numerals; searchers often write Class 3. Both mean the 7.3(m)(3) category.
“The firm decides the class.”
The definition in 7.3(m) says the designation is assigned by the Food and Drug Administration.
FAQ
What is a Class III recall?
It is the FDA recall classification for a situation in which use of, or exposure to, a violative product is not likely to cause adverse health consequences (21 CFR 7.3(m)(3)). The FDA assigns the number to indicate the relative degree of health hazard.
What is a Class 3 recall compared with Class 1 and Class 2?
Class I involves a reasonable probability of serious adverse health consequences or death. Class II involves temporary or medically reversible consequences, or a remote probability of serious ones. Class III is the lowest of the three. Full text is in the sources below.
Is a Class III recall a market withdrawal?
No. A market withdrawal under 7.3(j) involves a minor violation that would not be subject to legal action, or no violation. A recall under 7.3(g) involves a violation against which the agency would initiate legal action.
Who counts as affected by a recall?
The regulation’s term is consignee: anyone who received, purchased or used the recalled product (7.3(n)).
