Sampling a period underwear line takes 10–21 days per round and costs $100–$800 per round, depending on complexity. Most B2B programs require 2–4 rounds before bulk approval. Stock/reference samples can be free or low-cost; custom prototypes are always paid. Skipping sampling to save money is the single most expensive shortcut in period underwear sourcing.
Period underwear QC runs across 3 stages — Pre-Production Inspection (PPI), During Production Inspection (DPI), and Pre-Shipment Inspection (PSI). Apply AQL 2.5 as your standard for major defects on intimate apparel. Absorbency performance must be independently tested, not self-reported by the factory. Third-party inspection for any order above $10,000 is non-negotiable.

MOQ (minimum order quantity) for period underwear typically ranges from 300–500 pieces per SKU for basic reusable styles up to 3,000–5,000 pieces for fully custom designs with proprietary fabrics. MOQs exist because of fabric roll minimums, lamination batch economics, and production setup costs. Most growth-stage brands start at 300–500 pcs per style and scale from there.

The 7 customization levers for private label period underwear are: (1) fabric selection, (2) absorbency level, (3) silhouette and style, (4) size range and grading, (5) color, print and aesthetic, (6) branding touchpoints, and (7) technology and performance add-ons. New brands should prioritise waistband branding and packaging first — these deliver the highest perceived brand differentiation for the lowest incremental cost.

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.
