FDA Approved vs. Cleared vs. Registered vs. Listed: Definitions

"FDA approved" vs "cleared" vs "registered" vs "listed": what each term means, who may use it, and how FDA enforces the difference

These four phrases are not interchangeable, and the gap between them is one of the most common sources of misleading-claim enforcement FDA pursues. "Approved" and "cleared" describe two distinct premarket authorizations. "Registered" and "listed" describe an administrative database entry that involves no FDA review of the product at all. FDA's consistent position, stated across dozens of warning letters, is that blurring these terms in promotional material is misbranding, and the agency has taken action against mask makers, e-liquid sellers, compounding pharmacies, device firms, and supplement marketers for doing exactly that.

The short version

FDA approved is a premarket authorization: a Premarket Approval (PMA) for a Class III device, an approved New Drug Application (NDA) for a drug, or a Biologics License Application (BLA) for a biologic. It reflects FDA's affirmative finding of safety and effectiveness (or, for drugs, safety and efficacy) ³⁷⁵¹⁵².
FDA cleared applies to devices that went through 510(k) premarket notification. It means FDA found the device substantially equivalent to a legally marketed predicate for a specific indication. It is explicitly not the same as approval ³¹³⁷.
FDA registered / listed means an establishment has submitted its identifying information and a list of its products to FDA's Establishment Registration & Device Listing database. It is a record-keeping obligation, not a review, an approval, a clearance, or an endorsement ¹²⁵.
Several product categories, including dietary supplements and cosmetics, are not "approved" by FDA at all, so any "FDA approved" claim for them is false on its face ⁴³.

"FDA approved": an affirmative safety-and-effectiveness decision

For devices, "approved" is a term of art reserved for products with an approved PMA application in effect. FDA repeatedly contrasts uncleared or unapproved devices with the absence of "an approved application for premarket approval (PMA)," treating the device as adulterated when no such application exists ³¹³³³⁴³⁶³⁷³⁹⁴⁰⁴¹⁴². A Class III device cannot lawfully be marketed as "approved" unless FDA has actually granted the PMA.

For drugs and biologics, approval means an approved application (an NDA or BLA) is in effect before the product is introduced into interstate commerce. FDA describes this as the legal prerequisite for marketing a new drug: a new drug may not be marketed without "prior approval from FDA," and where "no approved application" is in effect, the product is an unapproved new drug whose marketing violates sections 505(a) and 301(d) of the FD&C Act ⁵¹⁵²⁵⁴⁵⁵⁵⁸⁵⁹⁶¹⁶². FDA stresses that approved products carry assurances that unapproved ones do not, including rigorous review of safety, efficacy, labeling, and manufacturing controls ⁵⁵⁵⁷⁵⁹⁶¹.

Only the sponsor of a product that has actually received one of these authorizations may describe it as "FDA approved," and only for the approved product and its approved use.

"FDA cleared": substantial equivalence under 510(k), not approval

"Cleared" is the correct term for devices that came to market through the 510(k) premarket notification pathway. FDA's position, stated plainly in warning letters, is that clearance means the agency "determined [the device] to be substantially equivalent" to a predicate, and that this "was not approved by the FDA" ³⁷. One letter describes a device "cleared with limitations," where the cleared indication was narrow and a broader use fell outside the 510(k) clearance ³¹.

When firms substitute "approved" for a device that was only cleared, FDA calls it misleading. In the SnoreRx letter, FDA objected that the labeling "contains statements that are misleading ... because such statements create an impression of official approval of a device due to clearance of a premarket notification submission," and reiterated that the device "was not approved by the FDA, but was determined to be substantially equivalent" ³⁷. In the Atossa matter, the MASCT System was advertised as "FDA-approved" when the devices were only cleared/substantially equivalent, and FDA flagged the discrepancy directly ¹⁸.

The distinction is substantive, not cosmetic: clearance rests on comparison to an existing predicate for a defined indication, while approval rests on FDA's independent finding of safety and effectiveness ³¹³⁴³⁷⁴⁰.

"FDA registered" and "listed": a database entry, not a verdict

Establishment registration and device listing are the terms most often abused, and FDA's rebuttal is the most scripted. The agency's standard language:

"FDA registration of a device establishment or assignment of a registration number does not denote FDA approval of the establishment or the device. Thus, references to a firm's establishment registration and registration number that create an impression of official FDA approval, clearance, authorization, certification, endorsement or other evaluation of the establishment or the devices are misleading and constitute misbranding. 21 CFR 807.39." ¹³⁵⁸⁹¹¹¹²¹³¹⁴

FDA also reminds firms that its Center for Devices and Radiological Health "does not issue device registration certificates," and that a database entry "merely denotes that the establishment has provided certain information to FDA" ¹²⁴⁵⁶⁸⁹¹¹¹²¹³¹⁴. Critically, a disclaimer does not cure the problem: FDA has said that boilerplate stating a certificate does not denote endorsement "do[es] not fix the problem if the overall presentation still creates a misleading impression" ¹⁴¹²²⁸³⁰.

So "registered" and "listed" are accurate only as literal statements of administrative status. The moment they are dressed up as certification, approval, or endorsement, FDA treats them as misbranding.

Categories FDA does not "approve" at all

For some product categories, "FDA approved" is not merely the wrong term but describes something that does not exist. FDA does not approve dietary supplements or their ingredients. In one supplement letter, the firm's FAQ claimed FDA had given ingredients "GRASE" status; FDA responded that the statements were false and misleading and misbranded the products under section 403(a)(1), stating flatly that "FDA does not approve dietary supplements or their ingredients" ⁴³. FDA has similarly treated skin-coloring "supplement" claims as cosmetic claims rather than approved-product claims ⁴³.

Related traps: a "supplement" that contains an approved drug ingredient (for example, lovastatin) can be excluded from the dietary-supplement definition under section 201(ff)(3)(B) and treated as an unapproved drug ⁴⁴, and a substance that is not a dietary ingredient at all (synthetic apoaequorin in the Prevagen matter) "could not be marketed as dietary supplements" regardless of labeling ⁵⁰.

The legal hooks FDA uses

Devices: 21 CFR 807.39 (registration/listing claims that imply approval, clearance, authorization, certification, or endorsement are misleading and constitute misbranding) ¹³⁵; adulteration where no approved PMA is in effect ³¹³³³⁴.
Drugs: marketing without an approved application violates FD&C Act sections 505(a) and 301(d); products so marketed are unapproved new drugs ⁵¹⁵²⁵⁴⁵⁶⁵⁹⁶¹. Labeling that lacks adequate directions for use compounds the misbranding ⁵²⁵⁴⁵⁸⁶⁰.
Supplements/foods: false or misleading labeling, including implied FDA approval, misbrands the product under section 403(a)(1) ⁴³.
FDA logo/seal: using the FDA logo in a way that suggests approval or endorsement is misleading, and FDA has warned that unauthorized use of its logo "may violate federal law and may subject responsible parties to civil and/or criminal liability" ²⁶³⁹.

The enforcement record: who got caught, and for what

The misclaim problem cuts across nearly every product line FDA regulates.

COVID-era masks and respirators. Firms marketed masks as "FDA Approved," "FDA Registered," "FDA certificated," and "official certificated ... FDA," often alongside disease claims like "Anti-COVID-19" and "meets all FDA requirements." FDA cited 21 CFR 807.39 and rejected mock "registration certificates" presented as government documents ¹³⁴⁸¹¹¹²¹⁴. Claims of "CE FDA dual certification" drew the same response ¹³.
Tobacco / e-liquids. E-liquids on ecigmates.co.uk were sold as "FDA (USA Approved)," and HelloCig's DIY nicotine products claimed the nicotine was an "FDA approved product." FDA said the claims misled consumers into believing the tobacco products were FDA approved ¹⁵¹⁶.
Compounded GLP-1 products. For compounded semaglutide and tirzepatide, FDA objected to "FDA Approved" and approval-implying claims such as "Same active ingredient as Wegovy and Ozempic" and "Same active ingredient as Mounjaro and Zepbound," reiterating that compounded drugs are not FDA-approved ¹⁹²⁰²¹²²²³²⁴²⁵.
Devices marketed as approved. The Atossa MASCT ("FDA-approved") and SnoreRx ("official approval ... due to clearance") letters are the cleanest examples of "approved" being used for a cleared device ¹⁸³⁷.
Antiseptics and registration-as-approval. The SOPURE antiseptic skin cleanser used "FDA" in a form resembling the FDA logo plus "U.S. FOOD & DRUG ADMINISTRATION" and touted its FDA "registrations" as confirmation of quality; FDA said registration is not approval ¹⁷.
Dietary supplements. Products claiming "FDA approved" or FDA "GRASE" status were misbranded under section 403(a)(1) ⁴³.

What FDA threatens when the claim is not fixed

Warning letters in this area close with a standard escalation menu. For failure to promptly correct, FDA cites potential seizure, injunction, and civil money penalties ⁶³⁶⁴⁶⁵⁶⁶⁷⁸⁸³, and reserves the right to take "further regulatory action ... without further notice" ⁶⁵⁶⁶⁷⁴⁸⁴. For device firms specifically, FDA warns that PMA applications for Class III devices will not be approved and Certificates to Foreign Governments will not be granted until the violations are corrected, and that federal agencies may consider the warning letter when awarding contracts ⁶³⁶⁴⁶⁷⁷³⁷⁹⁸⁵. For false promotional claims, the operative instruction is to "immediately cease making claims" and remove the offending material ⁷⁸⁸³.

Practical takeaways for regulatory and marketing review

Match the verb to the pathway: PMA / NDA / BLA -> "approved"; 510(k) -> "cleared"; establishment registration and device listing -> "registered" and "listed," and nothing more ¹³¹³⁷⁵¹.
Never let "registered" or "listed" imply review, certification, or endorsement; a disclaimer will not rescue a presentation that still creates that impression ¹⁴³⁰.
Do not claim "FDA approved" for a product category FDA does not approve (dietary supplements, cosmetics) ⁴³.
Treat the FDA logo as off-limits in commercial material; its use to imply endorsement is misbranding and can carry civil or criminal exposure ²⁶³⁹.
Cleared and approved are not synonyms, and stating the wrong one is itself a misleading claim even when the underlying authorization is genuine ³⁷.

A reader who wants to go deeper could ask Rhizome to pull the full text of any of these letters (for example, the SnoreRx or Atossa device letters, or the compounded-GLP-1 cluster), to map the specific FD&C Act sections cited in a given category, or to trend how often 807.39 registration-as-approval claims appear year over year.
