OEKO-TEX® STANDARD 100 vs GOTS: What Home Textile Buyers Need to Verify in 2026
Share
OEKO-TEX® STANDARD 100 and GOTS are both widely requested in home textile sourcing, but they answer different buyer questions. Treating them as interchangeable can create gaps in product claims, supplier qualification and document control.
This 2026 buyer guide explains what each standard covers, what evidence to request and when a project may need one or both.
The short answer
OEKO-TEX® STANDARD 100 is a product-safety certification for textiles tested for harmful substances. GOTS is a processing standard for textiles made with certified organic natural fibers, with environmental, human-rights, social and traceability requirements across relevant stages of the supply chain.
A STANDARD 100 certificate does not by itself prove that cotton is organic. A statement that a fabric uses organic cotton does not by itself prove that the finished product and its processing chain qualify for GOTS labeling.
| Question | OEKO-TEX® STANDARD 100 | GOTS |
|---|---|---|
| Main purpose | Tests textile articles for harmful substances | Verifies organic-fiber input and responsible processing through the textile chain |
| Typical buyer use | Product safety and market compliance support | Organic product programs and controlled organic claims |
| What can be certified | Materials and products from yarn to finished article | Eligible textiles made with certified organic natural fibers and covered processing/trading stages |
| Key document check | Valid certificate number, product scope and product class | Valid scope certificate, product scope and transaction documentation where applicable |
| Does it prove organic content? | No | Yes, within the applicable GOTS category and certified chain |
What OEKO-TEX® STANDARD 100 tells a buyer
According to the official OEKO-TEX® STANDARD 100 overview, every component of a certified article is tested against requirements for harmful substances. The requirements become stricter as skin contact becomes more intensive and the user becomes more sensitive.
That makes product class important for home textiles:
- Product Class 1 covers products for babies and children up to three years and has the strictest requirements.
- Product Class 2 covers products with direct skin contact, including bed linen.
- Product Class 3 covers products without direct skin contact.
- Product Class 4 covers decoration materials such as curtains and other home textiles with limited direct skin contact.
Do not accept a logo image or a supplier statement as the only evidence. Request the certificate, match the number to the offered product and use the official OEKO-TEX® Label Check. Confirm that the certificate is valid for the exact material, color, finish and product category being purchased.
What GOTS tells a buyer
GOTS covers more than a residue test. The standard addresses processing, manufacturing, packaging, labeling, trading and distribution of eligible textiles made with certified organic natural fibers. The official GOTS key-features guidance describes independent third-party certification across the textile supply chain.
GOTS Version 8.0 was released on 1 March 2026. It covers textiles made from at least 70% certified organic natural fibers and strengthens areas including due diligence, chemical controls, climate criteria, worker protection, microfibre management and textile-waste management. GOTS has announced a transition period, with Version 8.0 becoming fully effective on 1 March 2027. Buyers sourcing during 2026 should therefore confirm the certificate version, validity dates and transition status rather than assuming every document follows the same edition.
For a GOTS program, ask which entities are certified for spinning, weaving or knitting, wet processing, manufacturing and trading. Confirm that the offered product category and processing steps appear within the relevant scope. If the finished product will carry a GOTS label or if the buyer will make a GOTS claim, agree on transaction-certificate and labeling responsibilities before production.
When should a home textile buyer request both?
Both can be useful when a brand wants an organic-fiber story and also needs a familiar product-safety label for its market. The two certifications can complement each other, but their scopes must be checked separately.
For example, a baby bedding program may require:
- GOTS documentation for the organic cotton and certified processing chain;
- a product-safety requirement appropriate for baby products;
- brand-specific restricted-substance requirements;
- performance tests for shrinkage, colorfastness, seam strength and laundering;
- market-specific labeling and packaging review.
Certification does not replace the technical specification or quality-control plan. It answers a defined compliance question; it does not automatically guarantee fit, durability, shade consistency or workmanship.
Eight checks to put in the RFQ
- Name the exact certification and product class or label category required.
- Specify the sales market and applicable product type.
- Request current certificates before sample approval.
- Verify certificate numbers through the standard owner’s official database.
- Match the certificate scope to the fiber, fabric, finish and finished product.
- Confirm subcontractors and wet-processing stages are covered where required.
- Agree who will obtain transaction certificates and approve label artwork.
- Keep technical testing, inspection and certification requirements as separate RFQ lines.
Avoid claims that are broader than the documents
Do not market an entire collection as certified when only one input material is covered. Do not reuse a certificate for a different construction, color, coating or factory without confirming scope. Certification marks and wording are controlled; obtain approval before printing them on care labels, packaging, product pages or advertising.
