Kids’ Underwear — Manufacturer & Wholesale Supplier
Kids’ underwear built to OEKO-TEX Class I: soft waistbands, skin-safe dyes, tagless construction and school-pack formats with the documentation a tender needs.
What this category is really about
Children’s underwear has to satisfy the child and the compliance officer at the same time. Softness and a non-itch waistband are what gets a reorder; Class I material certification is what lets you sell it at all.

Customisation options
Not sure which construction fits?
Tell us the market, the price point and the wearing condition. We will recommend a construction rather than sell you the most expensive one — and we will say plainly when a price point is not achievable at the quality you have asked for.
How we de-risk an underwear order
Pattern room, not a pattern file
Grading is done per style against your target market size chart, then validated on a wearer before bulk production.
The same AQL 2.5 QC chain
AQL 2.5 final inspection on every shipment, inline checks at knitting, linking, boarding and pairing, plus an in-house lab for colourfastness, shrinkage, pilling and mmHg pressure.
Branding included in development
Waistband branding, labels and packaging are specified during sampling, not bolted on afterwards.
Consolidated with your sock orders
One shipment, one set of documents, one contact — if you buy both categories from us.
Frequently asked questions
What is the MOQ for kids’ underwear?
From 2,000 pieces per colour, per size set. Mixed sizes count towards the same colour, and mixed colours can be consolidated into one shipment.
How fast are samples and what do they cost?
Pre-production samples ship 7–10 days after tech-pack approval, by express, with a spec sheet. The sample fee is quoted per style and refunded in full once the bulk order is placed. Revisions are free until you approve the sample.
Can you handle packaging, labels and barcodes?
Yes. Printed belly bands, hangtags, header cards, hook boxes, gift boxes and multi-language inserts, plus GS1 barcode and SKU management for retail and Amazon. Packaging is quoted as a separate line so you can see exactly what it costs.
Do you own the factory that produces our order?
No — and we are deliberately clear about it. SOXMILL is the brand and the sourcing entity of Beijing Haifu Supply Chain Co., Ltd. Production runs through a network of partner mills in China that we audit and qualify before a single order is placed. We hold the specification, the QC chain, the documentation and the commercial responsibility. That is the part most buyers actually care about: somebody accountable when something goes wrong.
What is the bulk production lead time?
18–28 days from deposit and sample approval. Compression and heavy terry constructions sit at the longer end. You receive a photo and video progress report every week while your order runs.
What payment terms do you accept?
30% T/T deposit, balance against B/L copy · L/C at sight above USD 30,000. First orders from new markets may need a higher deposit — we stay flexible for verified buyers and repeat programs.
