RUO labeling
How does FDA decide what a product is 'intended' for if the label says something else?
Plain English first, then the primary source. Education, not legal advice.
Interpretation
In short: regulators read the whole picture, including marketing, customer communications, and what a seller knows about actual use.
Plain English
Under 21 CFR 201.128 (drugs) and 21 CFR 801.4 (devices), the intended use of a product is determined by objective intent, meaning the expressions of the seller or their representatives, or circumstances that the article is offered for a particular use, not just the words printed on the label.
FDA can look at labeling, advertising, oral or written statements by the seller, and the circumstances of distribution. A product marketed with claims that it treats, diagnoses, or improves a health condition can be regulated as a drug or device based on that marketing, even if the label disclaims medical use.
This standard exists because Congress and FDA did not want intended use to be something a seller could opt out of by choosing careful label language while sending a different message elsewhere.
Why it matters
- A testimonial, a sales rep's pitch, or a website claim can create regulatory exposure even when the physical label is compliant.
- This is the legal mechanism that connects marketing and claims work directly to product classification.
Where the answer becomes fact-specific
The Foundation does not manufacture legal conclusions. These points change the analysis and may require qualified regulatory counsel.
- The actual content of advertising, social media, sales scripts, and customer correspondence all factor into the analysis.
- Context matters: the same molecule sold to a university lab and sold to a retail wellness customer can be treated differently based on surrounding circumstances.
