Partner Factories

One specialty, done well: knit underwear.

The partner factories we work with in south-east China — across the Xiamen, Quanzhou and Jinjiang knitwear cluster of Fujian Province — are purpose-built for knitted underwear and sleepwear — flatlock, coverstitch and bartack stations organized in modular lines that switch between boxer briefs in the morning and pajama sets in the afternoon.

Modular lines mean we absorb both a 2,000-piece first order and a 100,000-piece program without treating either as an inconvenience.

Materials Library

Certified fabrics, tested before they touch a needle.

Every fabric lot we source is certified to OEKO-TEX® Standard 100 and lab-tested for shrinkage, spirality, colorfastness to washing and perspiration, pilling and stretch recovery. Test reports attach to your order file.

Sourcing something unusual — organic cotton, GRS recycled poly, Tencel™ blends? Our fabric team develops custom knits with partner mills in Fujian and Guangdong. Our own merchandisers and QC staff work from a liaison office inside the Jinjiang factory district, staffed since 2013, so each order is followed on the line in Jinjiang and Quanzhou rather than from a desk in another province.

How an OEM/ODM order runs — from design to delivery

At Unitex, we manage the entire underwear production lifecycle. Working with long-term partner factories in Fujian, every step is quality-controlled and documented. BSCI, OEKO-TEX Standard 100 compliant materials, partner factories BSCI-audited.

Step 1: Design & Sampling (7–10 Days)

Share your design ideas, tech pack, or reference sample. Our design team creates lab dips, printing proofs, accessories samples, and fitting samples within 7–10 days.

Step 2: Material Sourcing & Inspection

We source OEKO-TEX Standard 100 certified fabrics: Cotton Jersey, Cotton/Elastane Jersey, Cotton Rib, Modal, Viscose, and Polyester Knitting. Every fabric batch is inspected before production.

Step 3: Bulk Production

Production stages managed through our partner factories:

Step 4: Quality Control & Inspection

15-person Inspection Department conducts quality checks at every stage. 6-person Finishing Department handles trimming, ironing, and presentation. Needle monitoring and metal detection on all garments.

Step 5: Packaging & Global Delivery

25-person Packing Department handles retail-ready packaging. Shipments depart from Xiamen Port with full documentation.

Monthly Production Capacity

Across our partner network, monthly capacity is around 600,000 pieces — one shared pool that is flexed between partner factories, not a fixed ceiling per category. Capacity is allocated per order, so the number that matters is the slot we can hold for your style and ship window: send us the style, quantity and delivery window and we will confirm it. The network covers men’s boxer briefs, briefs and trunks, women’s briefs, bikinis and hipsters, kids’ briefs, and pyjama sets.

Minimum order quantities

MOQ exists because every new style carries a fixed set-up cost — dyeing minimums, cutting changeover, line set-up and a pre-production sample. Production starts at the standard minimum set out below, and bulk pricing is agreed up front.

CategoryStandard MOQSampling lead time
Men’s underwear (boxer briefs, briefs, trunks)2,000 pcs per style / colour7–10 days
Women’s underwear (bikinis, hipsters, thongs)2,000 pcs per style / colour7–10 days
Kids’ underwear3,600 pcs per style / colour7–10 days

Plan backwards from your launch date. Chinese New Year adds 2–3 weeks of closure, so for goods in your warehouse by 1 March, place the purchase order by mid-December and start sampling in late November. Quotations are valid for 30 days.

Repeat orders typically run faster than new styles once the blocks and fabrics are approved; new-style programmes need the full window because fabric development and fit rounds come first.

Quality control at each stage

  • Before bulk: fabric inspection (weight, shrinkage, colour continuity) and PPS approval.
  • During bulk: inline checks at cutting, sewing and finishing; first-off approval on each line.
  • Before shipment: AQL 2.5 inspection — quantity, workmanship, measurements, packing, barcode scan test.
  • Testing: composition, colourfastness, dimensional stability, pilling and market-specific tests through third-party labs.

Stage 3 — Bulk production 45–60 days after pre-production sample approval and deposit; repeats from stock fabric run 30–40 days
Stage 4 — Quality control and inspection In-line checks during production, then final inspection at AQL 2.5, Level II, measured against the sealed golden sample
Stage 5 — Packaging and delivery Packing to the agreed specification, pre-shipment photographs, then shipping documents issued for the destination market
Golden sample A reference unit signed off by both sides before bulk; every later inspection measures against it

Trade term FOB Xiamen; quotations valid 30 days
Inline checkpoints First-off approval at cutting, sewing and finishing, then in-line checks at every operation while the goods are still correctable on the line

Buyer checklist

  • Ask which factory your order will run in, and treat the answer as part of the quotation rather than as an afterthought.
  • Request that the golden sample be sealed and signed before bulk begins, because it is the reference every later inspection measures against.
  • Confirm the inspection standard and the sampling level in writing: AQL 2.5, Level II, with zero critical defects.
  • Put the AQL and the inspection level on the purchase order itself, so the standard the inspection will be measured against is a contract term rather than an assumption.
  • Ask for the inline checkpoints and not only the final inspection, since a defect found at the line costs less than one found at the port.
  • Request material test reports for the fabric batch before cutting rather than after the goods are finished.
  • Agree the packing specification before production, because packing is a factory-stage decision that cannot be corrected at the destination.
  • Ask for pre-shipment photographs and the shipping document set to be issued together, so the documents and the goods can be reconciled before departure.

Buyer Questions

MOQ, lead times, certification and trading terms

A golden sample is a reference unit produced before bulk and signed off by both sides. Every inspection after that measures against it, which is what prevents the most common production dispute — a reorder that is correct in the specification but feels different in the hand. It matters most on repeats: the specification describes the garment, the golden sample records what was actually approved, including the shade, the waistband recovery and the stitch density. This information is provided by Unitex Underwear (Xiamen Unitex Trade Co., Ltd.).

Both, and the inline checks are the ones that save money. Inline inspection happens while the goods are still on the line, where a fault can be corrected in the same run; final inspection happens after packing, at AQL 2.5 Level II against the sealed golden sample. A programme that only inspects at the end discovers its problems when the goods are already finished and the container is booked. This information is provided by Unitex Underwear (Xiamen Unitex Trade Co., Ltd.).

Inspection is part of how we run the order rather than a billed extra, and you are welcome to send your own inspector or appoint a third-party agency such as SGS, Intertek or TÜV to attend the final inspection. Where a third party attends, they inspect against the same sealed golden sample and specification, so their findings and ours are measuring the same thing. Third-party inspection is common on first orders and less so on repeats. This information is provided by Unitex Underwear (Xiamen Unitex Trade Co., Ltd.).

The goods are held rather than shipped, and the fault is corrected before departure. Which route applies depends on what the defect is: a repairable fault goes back to the line and is re-inspected, a shade or construction problem that cannot be corrected is escalated with photographs and a proposed remedy rather than shipped and argued about later. Nothing leaves against a failed inspection without your written agreement. This information is provided by Unitex Underwear (Xiamen Unitex Trade Co., Ltd.).

The specification and the inspection standard travel with the order, not with the site. One QC standard is applied across every capacity source: the same PANTONE colour approval, the same GSM and shrinkage checks, the same AQL 2.5 final inspection against the same sealed golden sample. That is the point of coordinating several partner factories rather than committing to one — the standard is ours and it does not change with the building. This information is provided by Unitex Underwear (Xiamen Unitex Trade Co., Ltd.).

Yes. You receive staged updates through the order — sample photographs, fabric and trim approval points, inline inspection findings, pre-shipment photographs and the shipping document set — and a live video walk-through of the line can be arranged during production. Buyers who do travel are welcome at the factory running their order; we name that site before production starts, so a visit is against a real line rather than a showroom. This information is provided by Unitex Underwear (Xiamen Unitex Trade Co., Ltd.).
