Trusted period underwear OEM manufacturer for brands in 4+ export regions
These are the figures buyers ask for on the first call: capacity, turnaround, and the certifications behind them. Ten years making one category — period, incontinence and maternity underwear.
Shanhao is a vertically integrated factory — knitting, cutting, bonding, sewing and packing happen under one roof at Gurao Town, Shantou, with the commercial team in Shenzhen. You are not talking to a trading house.

Your search does not fail because the product idea is weak. It fails when PFAS reports are missing, MOQ drains your first-order budget, samples take eight weeks, or compliance paperwork arrives after the container. Here is how we answer each of those.
01 The pain: the "factory" you found turns out to be an agent quoting a third party.
Our fix: the sewing floor is at Xianbohuan East Road, Gurao Town, Shantou — a public address you can verify. Shenzhen is sales only. Video call from the floor any working day.
02 The pain: your retailer now requires PFAS test evidence before onboarding.
Our fix: the leak barrier is specified PFAS-free, along with phthalates, parabens and hormone-disrupting chemicals. Test reports ship with the goods, not on request.
03 The pain: sampling takes a month and kills the launch window.
Our fix: 5–7 business days for a physical sample, with revisions run on the same pattern block so fit does not drift between rounds.
04 The pain: the supplier quietly changed the fabric and nobody told you.
Our fix: every roll is inspected and recorded against your spec before cutting — weight, shrinkage, colourfastness. The roll data goes into your order file.
05 The pain: one SKU takes off and the factory cannot scale with you.
Our fix: 600,000+ units a month in-house. Nothing is subcontracted out to a workshop we do not control.
06 The pain: MOQ is set so high that a first run swallows the whole budget.
Our fix: low-MOQ options for private-label launches, with OEM and ODM development, custom labels and packaging included in the same quote.
Custom engineering: absorbency, fabric and fit architecture
Most factories sell a stock block they rename. We engineer the four-layer stack around your target: absorbency, fabric, hand-feel, cut, and the packaging it lands in.
Fabric we knit, not just pick
Organic cotton, bamboo fibre, modal, recycled fabrics and OEKO-TEX® certified textiles, selected against your market and price point.
Patented four-layer core
Wicking top sheet, absorbent core, PFAS-free leak barrier and outer shell — assembled and absorbency-tested to the millilitre figure on your spec.
Fit for western bodies
Hipster, bikini brief, high waist, thong, boxer short and sleep overnight blocks, graded for the size curve your market actually buys.
Retail & FBA readiness
Custom labels, logo printing and packaging development, with cartons and barcoding prepared for marketplace intake.
What changes when brands switch to a direct factory
Three situations we see repeatedly, and what moved once production came in-house.
- Challenge
- Inconsistent absorbency between batches from a subcontracted supplier.
- Solution
- Single-factory production with in-line absorbency testing against a fixed ml target.
- Result
- Consistent unit quality across repeat runs, and a measurable fall in leak-related returns.
- Challenge
- A retailer onboarding deadline that required OEKO-TEX and PFAS evidence up front.
- Solution
- Sample in 5–7 business days, shipped alongside the material certificates and test reports.
- Result
- Onboarding cleared inside the buyer's window with no second sample round.
- Challenge
- A seasonal spike the previous supplier could not cover without subcontracting.
- Solution
- In-house capacity of 500,000 panties and 100,000 bras a month, scheduled ahead of peak.
- Result
- Replenishment held through the season without a quality change between runs.

Every product moves through five controlled stages before it ships — nothing skips ahead, and each stage ends with a recorded sign-off. This is the technical credibility behind the certifications.
Design & development
Custom fit, construction and a spec sheet built to your brief — or reverse-engineered from a sample you send us. Feasibility, indicative pricing and MOQ come back with it.
Pattern making & sampling
Physical samples cut, sewn and couriered in 5–7 business days. Revisions run on the same pattern block, then a signed golden sample stays on our floor.
Fabric inspection & testing
Certified, OEKO-TEX-tested materials checked for weight, shrinkage and colourfastness before a single roll reaches the cutting table.
Leak-proof layer integration
The patented four-layer absorbent core is assembled and quality-checked, then absorbency-tested against your target millilitre figure.
Final audit & global shipment
Packaging and label audit, final AQL inspection, then export to your market on your Incoterm.

How fast is the sample, and what does it really cost?

How do you ensure product quality?

Which countries and markets do you supply?

What is your monthly production capacity?
600,000+ units per month in-house — approximately 500,000 panties and 100,000 bras. Production is not subcontracted out, so quality and schedule stay under one roof.

A direct factory. Shantou Shanhao Knitting Co., Ltd. operates the vertically integrated plant at Gurao Town, Shantou, with the sales department in Longhua District, Shenzhen. Both addresses are published in the contact block below.
