# FDA Class II Medical Device

> Tampons are regulated by the FDA as Class II medical devices, not cosmetics. That means the FDA requires standardized absorbency labeling and a toxic shock syndrome warning, but it does NOT require ingredient disclosure or testing for heavy metals.

## Reality Check

**Claim:** Tampons are FDA-regulated, so they must be tested for safety.
**Reality:** They are regulated as Class II devices, which requires absorbency labeling and a TSS warning, but NOT ingredient disclosure or heavy-metal/PFAS testing. The 2024 study finding lead in 100% of tampons shows the gap.

## Overview

A surprising fact sits behind every tampon box: the FDA regulates tampons as **Class II medical devices**, the same moderate-risk category as things like powered wheelchairs and pregnancy tests. They are not cosmetics, and not food. This shapes exactly what is, and is not, required of them.

## What Class II requires

Because they are devices, tampons must clear the FDA's premarket notification (510(k)) process and follow specific rules:

- **Standardized [absorbency](/learn/specs/tampon-absorbency) labeling** so 'Regular' means the same thing across brands.
- A mandatory **[toxic shock syndrome](/learn/conditions/toxic-shock-syndrome) (TSS) warning** and usage guidance.
- General device controls for manufacturing and safety.

The FDA also issues advisory recommendations, asking that tampons be free of dioxin and pesticide residues and that brands disclose their bleaching process. But advisory is the key word.

## The gap that matters

Here is what Class II classification does NOT require, and why R3 scores tampons the way it does: **no pre-market ingredient disclosure, and no testing for [heavy metals](/learn/ingredients/heavy-metals) or PFAS.** A brand can sell a [tampon](/category/tampons) without ever telling you what is in it or proving it is free of contaminants. This is exactly why the 2024 study that found lead in 100% of tampons tested was possible: there are no regulatory limits for metals in menstrual products. The device framework governs absorbency and TSS, not chemical purity.

That gap is the whole reason a brand that voluntarily publishes independent lab testing stands out. The rules do not make them do it, so the ones that do are signaling real confidence.

## Also Known As

- Class II device
- 510(k) device
- moderate-risk device

## Where Found

- All tampons sold in the U.S.

## Label Guide

**Look for:**
- Standardized absorbency rating
- TSS warning
- Voluntary full-material disclosure and published testing

**Avoid / misleading:**
- Assuming FDA regulation means contaminant-tested
- No ingredient or testing disclosure beyond the required labels

## Who Is At Risk

- Anyone assuming 'FDA regulated' means contaminant-tested

## What Helps

Because the rules do not require it, favor brands that voluntarily disclose full materials and publish independent testing for metals and PFAS. The device framework only guarantees absorbency labeling and a TSS warning.

## How To Verify

Every legal tampon carries standardized absorbency and a TSS warning. For anything beyond that, you are relying on what the brand chooses to publish.

## Why R3 rewards voluntary testing

Because FDA Class II rules do not require ingredient disclosure or metal testing, R3 gives the most weight to brands that publish independent lab results, the proof the regulations do not demand.

## What This Does Not Cover

Class II status covers absorbency and TSS labeling, not chemical purity, ingredient disclosure, or metal/PFAS testing.

## R3 Bottom Line

- Tampons are FDA Class II medical devices, not cosmetics.
- Class II requires standardized absorbency labeling and a TSS warning.
- It does NOT require ingredient disclosure or testing for heavy metals or PFAS.
- That gap is why voluntarily published third-party testing is the signal that matters most.

## FAQ

### Are tampons regulated by the FDA?

Yes, as Class II medical devices, the same moderate-risk category as many medical products. The FDA requires standardized absorbency labeling and a toxic shock syndrome warning, and it issues advisory recommendations on dioxin and bleaching. But it does not require brands to disclose ingredients or test for heavy metals.

### Does the FDA test tampons for heavy metals?

No. The Class II device framework does not require pre-market ingredient disclosure or testing for heavy metals or PFAS. There are no regulatory limits for metals in menstrual products, which is why a 2024 study could find lead in 100% of tampons tested. Independent, voluntary lab testing by a brand is the only proof.

### What does Class II medical device mean for tampons?

It means tampons must clear the FDA's 510(k) notification process and carry standardized absorbency labels and a TSS warning. It is a moderate-risk classification. Crucially, it governs absorbency and toxic shock risk, not chemical purity, so it does not guarantee a tampon is free of contaminants.

### Why don't tampons list ingredients?

Because they are regulated as Class II medical devices, which does not require pre-market ingredient disclosure the way a food or cosmetic label might. Brands can disclose voluntarily, and the ones that publish full materials and testing are signaling confidence the rules do not force.

### Are tampons cosmetics?

No. Tampons are FDA Class II medical devices, not cosmetics. This matters because it sets different rules: standardized absorbency and a TSS warning are required, but ingredient disclosure and contaminant testing are not, leaving a gap that voluntary third-party testing fills.
