Is My Product a Medical Device? An FDA Self-Check for Amazon Sellers (2026)

Whether your product is an FDA medical device depends mainly on what you claim it does, not on what it is made of. FDA’s own determination page says to start by defining your product’s intended use and indications for use, then compare them against the device definition in section 201(h) of the FD&C Act and search for an existing classification (FDA, How to Determine if Your Product is a Medical Device, content current as of 09/29/2022, data checked 2026-10-14).

For Amazon sellers this matters twice. The same massager can be a general wellness product with one set of bullet points and a device with another, because FDA reads intent from “labeling claims, advertising matter, or oral or written statements” (21 CFR 801.4, eCFR, data checked 2026-10-14). And Amazon asks for FDA paperwork, such as a 510(k) number, before it lets medical devices through Health & Personal Care approval.

Below are the five steps and the tests FDA uses; they give you the criteria, not a ruling on any specific product.

Fact Block: What These Claims Rest On

Step 1: Write Down What Your Listing Claims

Before any database search, FDA asks you to define two things. Intended use is “The general purpose of the device or its function.” Indications for use describe the disease or condition the product addresses, including “a description of the patient population for which the device is intended” (FDA determination page, data checked 2026-10-14).

Most private-label sellers never wrote either down. Your listing wrote them for you. Under 21 CFR 801.4, intended use refers to “the objective intent of the persons legally responsible for the labeling,” and that intent “may, for example, be shown by labeling claims, advertising matter, or oral or written statements.” The same section adds that intent can show through “the design or composition of the article.”

So collect every claim the product makes, in every place a customer or regulator can read it:

• Title, bullets, description, and A+ content
• Packaging, inserts, and instructions
• Images, including text overlays and infographics
• Brand store, ads, influencer briefs, and your website

Then sort the claims into two piles: claims about general health or a healthy activity, and claims that name a disease, a condition, or a body function you change. The second pile is what Step 2 tests.

Step 2: Test the Claims Against the Statutory Device Definition

Section 201(h) of the FD&C Act, as FDA presents it, covers “An instrument, apparatus, implement, machine, contrivance, implant, in vitro reagent” and similar articles that meet one of three conditions:

Two points trip sellers up. First, the chemical-action clause separates many devices from drugs; FDA’s page notes that a non-device may fall under its drug or biologics centers. If you sell creams or pills, the closer reads are MoCRA for cosmetics and dietary supplements on Amazon.

Second, the word “device” in other laws means something else. An EPA pesticide device is a separate category with separate rules.

The definition excludes certain software functions under section 520(o); FDA routes app and software questions to [email protected].

Step 3: Check Where General Wellness Products Sit

For most fitness, sleep, and relaxation products, this step decides the answer. FDA’s General Wellness guidance (final, issued January 6, 2026) describes a compliance policy for low-risk products, and the determination page says a product “intended for general wellness use only, and is low risk, it may not be actively regulated by the FDA.”

The two wellness categories

The guidance gives two routes: an intended use that relates to “maintaining or encouraging a general state of health or a healthy activity,” or one linking a healthy lifestyle to reducing the risk or impact of certain chronic diseases.

The first category makes no reference to diseases: weight management, physical fitness, relaxation or stress management, mental acuity, self-esteem, sleep management, and sexual function. Examples from the guidance:

The second category may mention a chronic disease, but only where it is “well understood and accepted that healthy lifestyle choices may play an important role,” such as heart disease, high blood pressure, and type 2 diabetes.

The three low-risk questions

The guidance says that if the answer to any of these is yes, “the product is not low risk and is not covered by this guidance”:

1. Is the product invasive? (The guidance defines invasive as one that “penetrates or pierces the skin or mucous membranes”).
2. Is the product implanted?
3. Does it involve an intervention or technology that may pose a risk “such as risks from lasers or radiation exposure”?

FDA’s failing examples include tanning sunlamps, laser skin rejuvenation, and neurostimulation for memory, even with wellness-sounding claims. The guidance also notes that being Class I “does not necessarily mean that it is ’low risk’” for this policy.

Sensors and readings

Wearables that show heart rate, blood oxygen, or blood pressure get their own test. The 2026 guidance says such products are not general wellness products if their “labeling, advertising, user interface, or functionality” includes references to specific diseases or diagnostic thresholds, alerts that recommend clinical action, treatment guidance, or claims of “clinical equivalence, clinical accuracy, medical or clinical grade.” A bullet point that says “medical-grade accuracy” can move the product out of the wellness lane.

Step 4: Search the FDA Device Classification Database

If your claims pass Step 2’s device tests, the next question is which classification applies. FDA says classification “is risk based,” and that it has classified “approximately 1,700 different generic types of devices” grouped into medical specialty panels (Classify Your Medical Device, data checked 2026-10-14).

FDA describes two ways in: search by part of the device name, or browse the panel for your device’s specialty. The Product Classification Database (page last updated 10/12/2026) searches by Device, Product Code, Regulation Number, Device Class, and Submission Type, with options such as “510(K) Exempt.” Each result has a three-letter product code; FDA’s example is FLK, a clinical mercury thermometer.

A practical search order:

1. Search with two or three generic words for what the product does, not a brand name.
2. Open the closest match and read the classification regulation it cites.
3. Check comparable products in the 510(k), PMA, De Novo, and registration and listing databases; most Class I and some Class II devices will not appear in the premarket ones, because they are exempt.
4. If nothing fits, FDA’s 2022 determination page names De Novo as “a possible route to classify novel devices of low to moderate risk.”

A 510(k) exemption is narrower than it sounds. FDA’s exemptions page says exempt devices “must still comply with other requirements (known as regulatory controls)” unless the regulation says otherwise, and limitations sit in “21 CFR 862.9 through 892.9.” FDA’s General Controls page (content current as of 01/30/2026, data checked 2026-10-14) lists device registration and listing, misbranding, and current good manufacturing practices among the general controls, which apply to all three device classes.

Step 5: Ask FDA When the Answer Is Still Unclear

First, contact FDA’s industry education office (the 2022 determination page calls it DICE; the October 2026 exemptions page calls it the Office of Industry and Consumer Education). If that does not settle it, email [email protected]. For a formal determination, FDA says to “consider submitting a 513(g) Request.”

The procedure, including what a request should contain, is in FDA’s 513(g) guidance. The email route is informal help; 513(g) is FDA’s formal written response.

Where Amazon Fits In: Selling Medical Devices on Amazon

Amazon’s Health & Personal Care guide (Apr 1, 2026, data checked 2026-10-14) says medical devices “require FDA clearance based on device class,” lists an “FDA 510(k) clearance number for medical devices” among approval documents, and says that after you obtain FDA clearances, “Amazon reviews your documentation to verify compliance.” The mechanics are in category ungating and gated categories.

Three Amazon rules from the same guide connect to Step 1:

• “Prescription medical devices can’t be shipped through Fulfillment by Amazon (FBA),” and prescription devices appear on its prohibited list.
• “You can’t make claims that products diagnose, cure, treat, or prevent diseases without FDA approval.”
• Products using “FDA approved” language “without express approval” are prohibited.

Amazon’s guide summarizes device paperwork as registration and 510(k) clearance “for most Class II and III devices.” FDA’s own pages put most Class III devices on the PMA path instead, so read FDA’s classification for your product type, not the summary. After launch, notices about your listings tend to surface in Manage Your Compliance.

Common Mistakes

• Judging by the product, not the claims. Two identical massagers can land in different places because one listing says “relaxation” and the other names a condition.
• Forgetting images and A+ content. 21 CFR 801.4 counts advertising matter; an infographic is advertising.
• Treating “Class I” as “no rules.” Exempt from 510(k) still leaves registration, listing, and other general controls.
• Assuming wellness covers anything non-medical-sounding. Lasers, implants, and invasive products fail the low-risk test regardless of wording.
• Writing “FDA approved” loosely. Amazon bars that language without express approval, and a cleared or exempt device is not an approved one.
• Copying a competitor’s classification without reading its regulation, including the exemption limitations.

Self-Check Checklist

1. List every claim across title, bullets, images, A+, packaging, inserts, and ads.
2. Write one intended-use sentence and one indications-for-use sentence.
3. Test each claim against the three 201(h) conditions.
4. Check the two general wellness categories and the three low-risk questions.
5. For sensors, check the 2026 wording rules on diseases, alerts, and “clinical grade.”
6. Search the Product Classification Database by generic name; record the product code, class, and submission type.
7. Read the classification regulation and its .9 exemption limitations.
8. If still unclear, contact FDA’s industry education office, then DeviceDetermination, then consider 513(g).
9. Line up Amazon documents and recheck your product liability insurance cover.

Frequently Asked Questions

How do I know if my product is a medical device under FDA rules?

Define its intended use and indications for use from your own claims, test them against section 201(h), and search FDA’s Product Classification Database for a matching product type (FDA determination page, data checked 2026-10-14). If still unclear, FDA offers an email route and the formal 513(g) request.

Does a general wellness product need FDA clearance?

FDA’s General Wellness guidance (January 6, 2026) says low-risk products intended only for general wellness use may not be actively regulated. Invasive, implanted, or laser-type products are outside the policy, and so are claims that diagnose or treat a disease.

Can I sell a medical device on Amazon without a 510(k)?

It depends on the class. Many Class I and some Class II device types are exempt from 510(k), while most Class II devices need clearance and most Class III devices need PMA. Amazon may still ask for FDA documentation during approval, and prescription devices are on its prohibited list.

Conclusion

The FDA question is a claims question first. Write down what your listing says, test it against 201(h), check the general wellness lane, then find your product code in the classification database. That record is what Amazon approval, recall handling, and any FDA inquiry will start from.
