In one sentence
For sheets and duvet covers, look for a valid STANDARD 100 label and certificate number, commonly within direct-skin-contact Product Class 2. Enter the number in OEKO-TEX Label Check and confirm the named article and scope rather than trusting a marketplace badge alone.
STANDARD 100 product classes
| Class | Typical contact | Bedding relevance |
|---|---|---|
| 1 | Babies and children up to age 3 | Strictest limits for baby bedding |
| 2 | Direct skin contact | Bed linens and duvet covers commonly fit here |
| 3 | No direct skin contact | Some outer textile uses |
| 4 | Decoration materials | Curtain-like home textiles |
| Unstated badge | Unknown | Verify label and certificate before relying on it |
What this label answers
It does answer
Whether the certified textile article was tested under the standard for its stated product class.
It does not answer
Whether fiber is organic, climate-neutral, ethically sourced, cooling, durable or medically hypoallergenic.
Use the complete standard name
OEKO-TEX operates several labels and services. A generic 'OEKO-TEX certified' phrase is incomplete; identify STANDARD 100 and the exact label information.
The official standard describes testing based on intended use and increasingly strict requirements with closer or more sensitive skin contact.
Product class follows contact
OEKO-TEX lists bed linens under direct-skin-contact Product Class 2. Baby products belong to Class 1 with stricter requirements.
A comforter shell, fill and accessory can have different contact and scope questions. Confirm what the certificate names.
Use Label Check, not logo recognition
Scan the QR code or enter the certificate number in the official Label Check. Confirm validity, holder and article description align with the product offered.
A certificate for one supplier or fabric does not automatically cover every finished item sold by a marketplace merchant.
Do not turn substance testing into unrelated claims
STANDARD 100 does not mean organic and does not by itself establish biodegradability, recycled content, labor conditions or animal-welfare sourcing.
The GOTS bedding guide explains a different certification scope. Neither badge replaces the mandatory fiber label.
Record the claim with the product specification
Save the certificate number, product class, named article, fiber content and date checked. Then compare dimensions, warmth and care independently.
If the label cannot be validated or the scope is ambiguous, ask the seller rather than describing it as certified.
