Introduction
Most private label business cases start with one line on a tender sheet: the ex-factory unit price. For single-use absorbent hygiene products, that has served buying teams reasonably well. The products are standardised, the suppliers are mature, and the main variables are volume and price.
But reusable period underwear doesn’t behave that way. As we covered in the first blog in this series, German tampon revenue fell 11% in the year to July 2025, while period underwear revenue grew 39%, and similar trends are apparent across global markets – so the demand is clearly there. The harder question for sourcing and finance teams is whether the margin survives once the product reaches consumers.
A low quote from a labour-intensive offshore factory can look compelling on a spreadsheet. In this category, though, the costs that decide profitability usually sit outside the unit price. They show up in product performance, consistency of quality, compliance exposure and time your stock spends at sea. A defensible business case has to account for all these variables.
Apparel capability is not absorbent hygiene expertise
Many suppliers offering period underwear are lingerie or apparel manufacturers that have added an absorbent gusset to their existing women’s underwear. They are often good at cut, fit and fabric, but absorbency and leakproofing are different disciplines.
A period underwear gusset has to do several things:
- wick fluid away from the skin
- lock it into an absorbent core
- stop it reaching outer clothing
- keep doing all of this reliably through repeated washing
Getting that balance right draws on specialist knowledge of layer construction and barrier bonding backed by validated independent performance testing. A history of garment design alone isn’t enough.
When that expertise is missing, most manufacturers attempt to achieve higher absorbency by adding more layers of low-performing textiles. This creates a thicker gusset that makes the underwear more uncomfortable to wear, bulkier and less discreet.
What’s worse, the manual construction methods commonly used by apparel manufacturers rely on stitching to hold these layers together – but stitching through the gusset creates pathways for liquid to escape. Consumers experience this as period underwear that leaks. The retailer experiences it as weak repeat purchase.
The practical question for your business case is simple: has this supplier ever been accountable for absorbent performance, or only for apparel quality?
What manual assembly does to consistency and cost
Conventional period underwear is made by hand across dozens of separate cutting, sewing, bonding and finishing operations. Each step is a point where tolerances can drift between operators, shifts and production runs. That creates three issues for a sourcing director.
Quality variation. A sample made by a factory’s most skilled team doesn’t necessarily represent bulk production. Small differences in gusset placement, seam tension or barrier alignment can turn into leaks and fit complaints at volume.
Cost volatility. When labour is the largest input, wage rises, overtime and staff shortages flow straight into the unit price at the next negotiation.
Limited scalability. Capacity depends on headcount. Doubling an order means recruiting and training more operators, which is slow at exactly the moment a successful range needs fast replenishment.
None of this appears in the first quote, but it all appears by the second year.
Labour due diligence is becoming a market-access issue
The regulatory focus for EU retailers is widening from what is in the product to how the product was made. The EU Forced Labour Regulation (EU) 2024/3015 came into force on 13 December 2024 and from 14 December 2027 it applies to products in every sector and covers all stages of the supply chain. Authorities can bar affected products from the EU market and order their withdrawal and disposal (Regulation (EU) 2024/3015).
The timing matters for sourcing teams. Stock contracted in current procurement cycles will still be on the market when the prohibition takes effect, so the supply chain evidence has to be assembled well ahead of 2027. Labour-intensive factories, especially where working conditions are hard to verify independently, mean more audit effort and more documentation. They also carry a greater risk of disruption if a supplier or region comes under investigation.
None of this makes offshore sourcing non-compliant, but it does mean traceability and verifiable labour standards now have a cost, and that cost belongs in the business case next to the unit price.
Counting the cost of distance
Reusable absorbent hygiene products have a physical advantage that’s easy to overlook – one pair of period underwear replaces many months of disposables in a fraction of the volume. That means lower freight, warehousing and shelf costs for every Euro of consumer value.
Even so, it’s important to build lead times and transit variability into your calculations. For a fast-growing category, distance costs you in three ways:
- Cash is committed earlier, before a single unit sells.
- Safety stock has to be higher to cover longer, less reliable lead times.
- Replenishment is slow, so a range that sells through quickly risks empty shelves during its best weeks.
Many European companies are choosing to ‘nearshore’ their production to manufacturers within the EU so they benefit from shorter road transport and less capital in transit.
Putting the business case together
A total cost-of-ownership model for reusable period underwear should capture at least:
- Ex-factory unit price and expected price movement over the contract term
- Verified absorbency and leakproof performance data, and the test method behind them
- Expected return rate based on product performance
- Capacity to scale without quality drift
- Supply chain traceability and labour due diligence costs
- Lead time, transit variability and safety stock requirements
- Freight, warehousing and shelf space per unit
Weighted this way, the lowest quote is often not the lowest cost.
Frequently asked questions
Is period underwear profitable for private label retailers?
Absolutely, as it sells at a higher price point than disposables and builds repeat loyalty. Whether the margin holds depends heavily on sourcing, particularly product performance, return rates and supply reliability.
What should a sourcing business case include beyond unit price?
It should include performance evidence, scalability, compliance and traceability costs, lead times and logistics.
Next steps
Before your next supplier review, rebuild the business case for your reusable range around total lifecycle yield rather than unit price. Ask each prospective supplier for evidence on:
- absorbent performance
- consistent quality standards
- production capacity
- labour traceability
- realistic lead times
Then model what each gap would cost you.
The next blog in this series looks at how to de-risk supplier selection, including the performance testing and chemical compliance checks your RFP should mandate.
