For Southeast Asia manufacturers exporting women's underwear, understanding certification requirements is critical for accessing premium markets. Two dominant standards govern this space: GOTS (Global Organic Textile Standard) and OEKO-TEX Standard 100. While both address textile safety and sustainability, they serve different purposes and buyer expectations.
GOTS vs OEKO-TEX: Key Differences for Women's Underwear Manufacturers
| Feature | GOTS (Global Organic Textile Standard) | OEKO-TEX Standard 100 |
|---|---|---|
| Primary Focus | Organic fiber certification from farm to finished product | Harmful substance testing for all textile components |
| Minimum Organic Content | 70% for 'made with organic' label, 95%+ for 'organic' grade | No organic fiber requirement - focuses on chemical safety |
| Testing Scope | Entire supply chain: harvesting, processing, manufacturing, labeling | All components including threads, buttons, zippers, foam, prints |
| Product Classes | Two label grades based on organic fiber percentage | Four classes: Class 1 (baby), Class 2 (direct skin like underwear), Class 3 (no direct contact), Class 4 (home textiles) |
| Certification Validity | Requires Transaction Certificate (TC) for each shipment | Annual certification with certificate number verification |
| Market Access | Premium organic/sustainable markets (EU, North America) | Mandatory for EU market access, widely recognized globally |
| Cost Implication | Higher due to supply chain auditing and organic fiber premium | Moderate, testing-based certification |
GOTS Version 8.0, released in March 2026, introduced advanced supply chain accountability with mandatory due diligence, enhanced chemical and climate criteria, and new circularity requirements [4]. This update makes GOTS certification more rigorous but also more valuable for brands targeting environmentally conscious consumers.
OEKO-TEX Standard 100 remains the baseline requirement for EU market access, testing over 1,000 regulated and harmful substances. For women's underwear specifically, Class 2 certification (direct skin contact products) is mandatory. The standard covers all textile components - not just the fabric, but also threads, elastic bands, prints, and any accessories [3].
Ingredient labelling is when you label a component of the final product as GOTS or OEKO-TEX certified. Companies often do this to make you think their product is certified. The only document that verifies a specific fabric is certified is the Transaction Certificate. This is issued for each individual shipment [5].
This warning from Reddit's r/moderatelygranolamoms community highlights a critical issue: greenwashing through component certification. Some manufacturers certify only individual components (like organic cotton fabric) while the final product remains uncertified. B2B buyers on Alibaba.com should request the Transaction Certificate (TC) for each shipment, not just the Scope Certificate, to verify authentic certification [5].
