What Certifications Matter for Period Underwear?
For most markets, OEKO-TEX® STANDARD 100 (Class II) is the baseline requirement — it confirms the fabric is free of harmful substances. PFAS-free verification via third-party lab testing is now non-negotiable following 2025 US and EU regulations. BSCI or SEDEX audits satisfy European retailer ethical sourcing requirements. GOTS is relevant for organic cotton styles. Together, these four form the minimum certification stack for any brand targeting the US, EU, or UK market.
Choosing the right period underwear manufacturer comes down to eight factors: technical construction expertise, material certifications (OEKO-TEX, PFAS-free), MOQ flexibility, quality control systems, customisation capability, production capacity, communication standards, and ethical compliance. Vet every factory against a structured scorecard before committing. Sampling costs USD 80–300 per style; bulk lead times typically run 35–45 days from approved sample.
