Starting a period underwear brand requires defining a clear niche, validating demand, choosing an OEM or private-label manufacturing model, and budgeting $12,000–$130,000 for the full launch cycle. With an MOQ of 500–1,000 units, a reliable manufacturer, and a focused marketing strategy, most founders reach their first sale within 10–12 months of beginning the process.

OEM means you supply the design and the manufacturer builds to your specs — maximum control, highest investment. ODM means the manufacturer provides existing designs you customise — faster and lower-risk. Private label means buying finished or near-finished product and adding your branding — the fastest route to market with the least flexibility. Most brands start with private label, move to ODM as they validate demand, then graduate to full OEM.

Period underwear ex-factory wholesale cost ranges from $3.70 to $12.00 per pair, depending on construction complexity, absorbency level, and order volume. At 1,000 units, expect to pay $6–9 per pair ex-works China. Landed cost (including freight and duties) adds $1.50–3.00 per unit. Retail pricing by established brands typically lands at $20–50, which implies a 4–6× markup from factory cost.

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.
